11 # NOTE:
12 # MaskedEdit controls are based on a suggestion made on [wxPython-Users] by
13 # Jason Hihn, and borrows liberally from Will Sadkin's original masked edit
14 # control for time entry, TimeCtrl (which is now rewritten using this
15 # control!).
16 #
17 # MaskedEdit controls do not normally use validators, because they do
18 # careful manipulation of the cursor in the text window on each keystroke,
19 # and validation is cursor-position specific, so the control intercepts the
20 # key codes before the validator would fire. However, validators can be
21 # provided to do data transfer to the controls.

56 ====================
57 Masked Edit Overview
58 ====================
59
60 masked.TextCtrl:
61 is a sublassed text control that can carefully control the user's input
62 based on a mask string you provide.
63
64 General usage example::
65
66 control = masked.TextCtrl( win, -1, '', mask = '(###) ###-####')
67
68 The example above will create a text control that allows only numbers to be
69 entered and then only in the positions indicated in the mask by the # sign.
70
71 masked.ComboBox:
72 is a similar subclass of wxComboBox that allows the same sort of masking,
73 but also can do auto-complete of values, and can require the value typed
74 to be in the list of choices to be colored appropriately.
75
76 masked.Ctrl:
77 is actually a factory function for several types of masked edit controls:
78
79 ================= ==================================================
80 masked.TextCtrl standard masked edit text box
81 masked.ComboBox adds combobox capabilities
82 masked.IpAddrCtrl adds special semantics for IP address entry
83 masked.TimeCtrl special subclass handling lots of types as values
84 masked.NumCtrl special subclass handling numeric values
85 ================= ==================================================
86
87 It works by looking for a *controlType* parameter in the keyword
88 arguments of the control, to determine what kind of instance to return.
89 If not specified as a keyword argument, the default control type returned
90 will be masked.TextCtrl.
91
92 Each of the above classes has its own set of arguments, but masked.Ctrl
93 provides a single "unified" interface for masked controls.
94
95 What follows is a description of how to configure the generic masked.TextCtrl
96 and masked.ComboBox; masked.NumCtrl and masked.TimeCtrl have their own demo
97 pages and interface descriptions.
98
99 =========================
100
101 Initialization Parameters
102 -------------------------
103 mask
104 Allowed mask characters and function:
105
106 ========= ==========================================================
107 Character Function
108 ========= ==========================================================
109 # Allow numeric only (0-9)
110 N Allow letters and numbers (0-9)
111 A Allow uppercase letters only
112 a Allow lowercase letters only
113 C Allow any letter, upper or lower
114 X Allow string.letters, string.punctuation, string.digits
115 & Allow string.punctuation only (doesn't include all unicode symbols)
116 \* Allow any visible character
117 | explicit field boundary (takes no space in the control; allows mix
118 of adjacent mask characters to be treated as separate fields,
119 eg: '&|###' means "field 0 = '&', field 1 = '###'", but there's
120 no fixed characters in between.
121 ========= ==========================================================
122
123
124 These controls define these sets of characters using string.letters,
125 string.uppercase, etc. These sets are affected by the system locale
126 setting, so in order to have the masked controls accept characters
127 that are specific to your users' language, your application should
128 set the locale.
129 For example, to allow international characters to be used in the
130 above masks, you can place the following in your code as part of
131 your application's initialization code::
132
133 import locale
134 locale.setlocale(locale.LC_ALL, '')
135
136 The controls now also support (by popular demand) all "visible" characters,
137 by use of the * mask character, including unicode characters above
138 the standard ANSI keycode range.
139 Note: As string.punctuation doesn't typically include all unicode
140 symbols, you will have to use includechars to get some of these into
141 otherwise restricted positions in your control, such as those specified
142 with &.
143
144 Using these mask characters, a variety of template masks can be built. See
145 the demo for some other common examples include date+time, social security
146 number, etc. If any of these characters are needed as template rather
147 than mask characters, they can be escaped with \, ie. \N means "literal N".
148 (use \\ for literal backslash, as in: r'CCC\\NNN'.)
149
150
151 *Note:*
152 Masks containing only # characters and one optional decimal point
153 character are handled specially, as "numeric" controls. Such
154 controls have special handling for typing the '-' key, handling
155 the "decimal point" character as truncating the integer portion,
156 optionally allowing grouping characters and so forth.
157 There are several parameters and format codes that only make sense
158 when combined with such masks, eg. groupChar, decimalChar, and so
159 forth (see below). These allow you to construct reasonable
160 numeric entry controls.
161
162 *Note:*
163 Changing the mask for a control deletes any previous field classes
164 (and any associated validation or formatting constraints) for them.
165
166 useFixedWidthFont
167 By default, masked edit controls use a fixed width font, so that
168 the mask characters are fixed within the control, regardless of
169 subsequent modifications to the value. Set to False if having
170 the control font be the same as other controls is required. (This is
171 a control-level parameter.)
172
173 defaultEncoding
174 (Applies to unicode systems only) By default, the default unicode encoding
175 used is latin1, or iso-8859-1. If necessary, you can set this control-level
176 parameter to govern the codec used to decode your keyboard inputs.
177 (This is a control-level parameter.)
178
179 formatcodes
180 These other properties can be passed to the class when instantiating it:
181 Formatcodes are specified as a string of single character formatting
182 codes that modify behavior of the control::
183
184 _ Allow spaces
185 ! Force upper
186 ^ Force lower
187 R Right-align field(s)
188 r Right-insert in field(s) (implies R)
189 < Stay in field until explicit navigation out of it
190
191 > Allow insert/delete within partially filled fields (as
192 opposed to the default "overwrite" mode for fixed-width
193 masked edit controls.) This allows single-field controls
194 or each field within a multi-field control to optionally
195 behave more like standard text controls.
196 (See EMAIL or phone number autoformat examples.)
197
198 *Note: This also governs whether backspace/delete operations
199 shift contents of field to right of cursor, or just blank the
200 erased section.
201
202 Also, when combined with 'r', this indicates that the field
203 or control allows right insert anywhere within the current
204 non-empty value in the field. (Otherwise right-insert behavior
205 is only performed to when the entire right-insertable field is
206 selected or the cursor is at the right edge of the field.*
207
208
209 , Allow grouping character in integer fields of numeric controls
210 and auto-group/regroup digits (if the result fits) when leaving
211 such a field. (If specified, .SetValue() will attempt to
212 auto-group as well.)
213 ',' is also the default grouping character. To change the
214 grouping character and/or decimal character, use the groupChar
215 and decimalChar parameters, respectively.
216 Note: typing the "decimal point" character in such fields will
217 clip the value to that left of the cursor for integer
218 fields of controls with "integer" or "floating point" masks.
219 If the ',' format code is specified, this will also cause the
220 resulting digits to be regrouped properly, using the current
221 grouping character.
222 - Prepend and reserve leading space for sign to mask and allow
223 signed values (negative #s shown in red by default.) Can be
224 used with argument useParensForNegatives (see below.)
225 0 integer fields get leading zeros
226 D Date[/time] field
227 T Time field
228 F Auto-Fit: the control calulates its size from
229 the length of the template mask
230 V validate entered chars against validRegex before allowing them
231 to be entered vs. being allowed by basic mask and then having
232 the resulting value just colored as invalid.
233 (See USSTATE autoformat demo for how this can be used.)
234 S select entire field when navigating to new field
235
236 fillChar
237
238 defaultValue
239 These controls have two options for the initial state of the control.
240 If a blank control with just the non-editable characters showing
241 is desired, simply leave the constructor variable fillChar as its
242 default (' '). If you want some other character there, simply
243 change the fillChar to that value. Note: changing the control's fillChar
244 will implicitly reset all of the fields' fillChars to this value.
245
246 If you need different default characters in each mask position,
247 you can specify a defaultValue parameter in the constructor, or
248 set them for each field individually.
249 This value must satisfy the non-editable characters of the mask,
250 but need not conform to the replaceable characters.
251
252 groupChar
253
254 decimalChar
255 These parameters govern what character is used to group numbers
256 and is used to indicate the decimal point for numeric format controls.
257 The default groupChar is ',', the default decimalChar is '.'
258 By changing these, you can customize the presentation of numbers
259 for your location.
260
261 Eg::
262
263 formatcodes = ',', groupChar='\'' allows 12'345.34
264 formatcodes = ',', groupChar='.', decimalChar=',' allows 12.345,34
265
266 (These are control-level parameters.)
267
268 shiftDecimalChar
269 The default "shiftDecimalChar" (used for "backwards-tabbing" until
270 shift-tab is fixed in wxPython) is '>' (for QUERTY keyboards.) for
271 other keyboards, you may want to customize this, eg '?' for shift ',' on
272 AZERTY keyboards, ':' or ';' for other European keyboards, etc.
273 (This is a control-level parameter.)
274
275 useParensForNegatives=False
276 This option can be used with signed numeric format controls to
277 indicate signs via () rather than '-'.
278 (This is a control-level parameter.)
279
280 autoSelect=False
281 This option can be used to have a field or the control try to
282 auto-complete on each keystroke if choices have been specified.
283
284 autoCompleteKeycodes=[]
285 By default, DownArrow, PageUp and PageDown will auto-complete a
286 partially entered field. Shift-DownArrow, Shift-UpArrow, PageUp
287 and PageDown will also auto-complete, but if the field already
288 contains a matched value, these keys will cycle through the list
289 of choices forward or backward as appropriate. Shift-Up and
290 Shift-Down also take you to the next/previous field after any
291 auto-complete action.
292
293 Additional auto-complete keys can be specified via this parameter.
294 Any keys so specified will act like PageDown.
295 (This is a control-level parameter.)
296
297
298
299 Validating User Input
300 =====================
301 There are a variety of initialization parameters that are used to validate
302 user input. These parameters can apply to the control as a whole, and/or
303 to individual fields:
304
305 ===================== ==================================================================
306 excludeChars A string of characters to exclude even if otherwise allowed
307 includeChars A string of characters to allow even if otherwise disallowed
308 validRegex Use a regular expression to validate the contents of the text box
309 validRange Pass a rangeas list (low,high) to limit numeric fields/values
310 choices A list of strings that are allowed choices for the control.
311 choiceRequired value must be member of choices list
312 compareNoCase Perform case-insensitive matching when validating against list
313 *Note: for masked.ComboBox, this defaults to True.*
314 emptyInvalid Boolean indicating whether an empty value should be considered
315 invalid
316
317 validFunc A function to call of the form: bool = func(candidate_value)
318 which will return True if the candidate_value satisfies some
319 external criteria for the control in addition to the the
320 other validation, or False if not. (This validation is
321 applied last in the chain of validations.)
322
323 validRequired Boolean indicating whether or not keys that are allowed by the
324 mask, but result in an invalid value are allowed to be entered
325 into the control. Setting this to True implies that a valid
326 default value is set for the control.
327
328 retainFieldValidation False by default; if True, this allows individual fields to
329 retain their own validation constraints independently of any
330 subsequent changes to the control's overall parameters.
331 (This is a control-level parameter.)
332
333 validator Validators are not normally needed for masked controls, because
334 of the nature of the validation and control of input. However,
335 you can supply one to provide data transfer routines for the
336 controls.
337 raiseOnInvalidPaste False by default; normally a bad paste simply is ignored with a bell;
338 if True, this will cause a ValueError exception to be thrown,
339 with the .value attribute of the exception containing the bad value.
340 ===================== ==================================================================
341
342
343 Coloring Behavior
344 =================
345 The following parameters have been provided to allow you to change the default
346 coloring behavior of the control. These can be set at construction, or via
347 the .SetCtrlParameters() function. Pass a color as string e.g. 'Yellow':
348
349 ======================== =======================================================================
350 emptyBackgroundColour Control Background color when identified as empty. Default=White
351 invalidBackgroundColour Control Background color when identified as Not valid. Default=Yellow
352 validBackgroundColour Control Background color when identified as Valid. Default=white
353 ======================== =======================================================================
354
355
356 The following parameters control the default foreground color coloring behavior of the
357 control. Pass a color as string e.g. 'Yellow':
358
359 ======================== ======================================================================
360 foregroundColour Control foreground color when value is not negative. Default=Black
361 signedForegroundColour Control foreground color when value is negative. Default=Red
362 ======================== ======================================================================
363
364
365 Fields
366 ======
367 Each part of the mask that allows user input is considered a field. The fields
368 are represented by their own class instances. You can specify field-specific
369 constraints by constructing or accessing the field instances for the control
370 and then specifying those constraints via parameters.
371
372 fields
373 This parameter allows you to specify Field instances containing
374 constraints for the individual fields of a control, eg: local
375 choice lists, validation rules, functions, regexps, etc.
376 It can be either an ordered list or a dictionary. If a list,
377 the fields will be applied as fields 0, 1, 2, etc.
378 If a dictionary, it should be keyed by field index.
379 the values should be a instances of maskededit.Field.
380
381 Any field not represented by the list or dictionary will be
382 implicitly created by the control.
383
384 Eg::
385
386 fields = [ Field(formatcodes='_r'), Field('choices=['a', 'b', 'c']) ]
387
388 Or::
389
390 fields = {
391 1: ( Field(formatcodes='_R', choices=['a', 'b', 'c']),
392 3: ( Field(choices=['01', '02', '03'], choiceRequired=True)
393 }
394
395 The following parameters are available for individual fields, with the
396 same semantics as for the whole control but applied to the field in question:
397
398 ============== =============================================================================
399 fillChar if set for a field, it will override the control's fillChar for that field
400 groupChar if set for a field, it will override the control's default
401 defaultValue sets field-specific default value; overrides any default from control
402 compareNoCase overrides control's settings
403 emptyInvalid determines whether field is required to be filled at all times
404 validRequired if set, requires field to contain valid value
405 ============== =============================================================================
406
407 If any of the above parameters are subsequently specified for the control as a
408 whole, that new value will be propagated to each field, unless the
409 retainFieldValidation control-level parameter is set.
410
411 ============== ==============================
412 formatcodes Augments control's settings
413 excludeChars ' ' '
414 includeChars ' ' '
415 validRegex ' ' '
416 validRange ' ' '
417 choices ' ' '
418 choiceRequired ' ' '
419 validFunc ' ' '
420 ============== ==============================
421
422
423
424 Control Class Functions
425 =======================
426 .GetPlainValue(value=None)
427 Returns the value specified (or the control's text value
428 not specified) without the formatting text.
429 In the example above, might return phone no='3522640075',
430 whereas control.GetValue() would return '(352) 264-0075'
431 .ClearValue()
432 Returns the control's value to its default, and places the
433 cursor at the beginning of the control.
434 .SetValue()
435 Does "smart replacement" of passed value into the control, as does
436 the .Paste() method. As with other text entry controls, the
437 .SetValue() text replacement begins at left-edge of the control,
438 with missing mask characters inserted as appropriate.
439 .SetValue will also adjust integer, float or date mask entry values,
440 adding commas, auto-completing years, etc. as appropriate.
441 For "right-aligned" numeric controls, it will also now automatically
442 right-adjust any value whose length is less than the width of the
443 control before attempting to set the value.
444 If a value does not follow the format of the control's mask, or will
445 not fit into the control, a ValueError exception will be raised.
446
447 Eg::
448
449 mask = '(###) ###-####'
450 .SetValue('1234567890') => '(123) 456-7890'
451 .SetValue('(123)4567890') => '(123) 456-7890'
452 .SetValue('(123)456-7890') => '(123) 456-7890'
453 .SetValue('123/4567-890') => illegal paste; ValueError
454
455 mask = '#{6}.#{2}', formatcodes = '_,-',
456 .SetValue('111') => ' 111 . '
457 .SetValue(' %9.2f' % -111.12345 ) => ' -111.12'
458 .SetValue(' %9.2f' % 1234.00 ) => ' 1,234.00'
459 .SetValue(' %9.2f' % -1234567.12345 ) => insufficient room; ValueError
460
461 mask = '#{6}.#{2}', formatcodes = '_,-R' # will right-adjust value for right-aligned control
462 .SetValue('111') => padded value misalignment ValueError: " 111" will not fit
463 .SetValue('%.2f' % 111 ) => ' 111.00'
464 .SetValue('%.2f' % -111.12345 ) => ' -111.12'
465
466
467 .IsValid(value=None)
468 Returns True if the value specified (or the value of the control
469 if not specified) passes validation tests
470 .IsEmpty(value=None)
471 Returns True if the value specified (or the value of the control
472 if not specified) is equal to an "empty value," ie. all
473 editable characters == the fillChar for their respective fields.
474 .IsDefault(value=None)
475 Returns True if the value specified (or the value of the control
476 if not specified) is equal to the initial value of the control.
477
478 .Refresh()
479 Recolors the control as appropriate to its current settings.
480
481 .SetCtrlParameters(\*\*kwargs)
482 This function allows you to set up and/or change the control parameters
483 after construction; it takes a list of key/value pairs as arguments,
484 where the keys can be any of the mask-specific parameters in the constructor.
485
486 Eg::
487
488 ctl = masked.TextCtrl( self, -1 )
489 ctl.SetCtrlParameters( mask='###-####',
490 defaultValue='555-1212',
491 formatcodes='F')
492
493 .GetCtrlParameter(parametername)
494 This function allows you to retrieve the current value of a parameter
495 from the control.
496
497 *Note:* Each of the control parameters can also be set using its
498 own Set and Get function. These functions follow a regular form:
499 All of the parameter names start with lower case; for their
500 corresponding Set/Get function, the parameter name is capitalized.
501
502 Eg::
503
504 ctl.SetMask('###-####')
505 ctl.SetDefaultValue('555-1212')
506 ctl.GetChoiceRequired()
507 ctl.GetFormatcodes()
508
509 *Note:* After any change in parameters, the choices for the
510 control are reevaluated to ensure that they are still legal. If you
511 have large choice lists, it is therefore more efficient to set parameters
512 before setting the choices available.
513
514 .SetFieldParameters(field_index, \*\*kwargs)
515 This function allows you to specify change individual field
516 parameters after construction. (Indices are 0-based.)
517
518 .GetFieldParameter(field_index, parametername)
519 Allows the retrieval of field parameters after construction
520
521
522 The control detects certain common constructions. In order to use the signed feature
523 (negative numbers and coloring), the mask has to be all numbers with optionally one
524 decimal point. Without a decimal (e.g. '######', the control will treat it as an integer
525 value. With a decimal (e.g. '###.##'), the control will act as a floating point control
526 (i.e. press decimal to 'tab' to the decimal position). Pressing decimal in the
527 integer control truncates the value. However, for a true numeric control,
528 masked.NumCtrl provides all this, and true numeric input/output support as well.
529
530
531 Check your controls by calling each control's .IsValid() function and the
532 .IsEmpty() function to determine which controls have been a) filled in and
533 b) filled in properly.
534
535
536 Regular expression validations can be used flexibly and creatively.
537 Take a look at the demo; the zip-code validation succeeds as long as the
538 first five numerals are entered. the last four are optional, but if
539 any are entered, there must be 4 to be valid.
540
541 masked.Ctrl Configuration
542 =========================
543 masked.Ctrl works by looking for a special *controlType*
544 parameter in the variable arguments of the control, to determine
545 what kind of instance to return.
546 controlType can be one of::
547
548 controlTypes.TEXT
549 controlTypes.COMBO
550 controlTypes.IPADDR
551 controlTypes.TIME

567 DEVELOPER COMMENTS:
568
569 Naming Conventions
570 ------------------
571 All methods of the Mixin that are not meant to be exposed to the external
572 interface are prefaced with '_'. Those functions that are primarily
573 intended to be internal subroutines subsequently start with a lower-case
574 letter; those that are primarily intended to be used and/or overridden
575 by derived subclasses start with a capital letter.
576
577 The following methods must be used and/or defined when deriving a control
578 from MaskedEditMixin. NOTE: if deriving from a *masked edit* control
579 (eg. class IpAddrCtrl(masked.TextCtrl) ), then this is NOT necessary,
580 as it's already been done for you in the base class.
581
582 ._SetInitialValue()
583 This function must be called after the associated base
584 control has been initialized in the subclass __init__
585 function. It sets the initial value of the control,
586 either to the value specified if non-empty, the
587 default value if specified, or the "template" for
588 the empty control as necessary. It will also set/reset
589 the font if necessary and apply formatting to the
590 control at this time.
591
592 ._GetSelection()
593 REQUIRED
594 Each class derived from MaskedEditMixin must define
595 the function for getting the start and end of the
596 current text selection. The reason for this is
597 that not all controls have the same function name for
598 doing this; eg. wx.TextCtrl uses .GetSelection(),
599 whereas we had to write a .GetMark() function for
600 wxComboBox, because .GetSelection() for the control
601 gets the currently selected list item from the combo
602 box, and the control doesn't (yet) natively provide
603 a means of determining the text selection.
604 ._SetSelection()
605 REQUIRED
606 Similarly to _GetSelection, each class derived from
607 MaskedEditMixin must define the function for setting
608 the start and end of the current text selection.
609 (eg. .SetSelection() for masked.TextCtrl, and .SetMark() for
610 masked.ComboBox.
611
612 ._GetInsertionPoint()
613 ._SetInsertionPoint()
614 REQUIRED
615 For consistency, and because the mixin shouldn't rely
616 on fixed names for any manipulations it does of any of
617 the base controls, we require each class derived from
618 MaskedEditMixin to define these functions as well.
619
620 ._GetValue()
621 ._SetValue() REQUIRED
622 Each class derived from MaskedEditMixin must define
623 the functions used to get and set the raw value of the
624 control.
625 This is necessary so that recursion doesn't take place
626 when setting the value, and so that the mixin can
627 call the appropriate function after doing all its
628 validation and manipulation without knowing what kind
629 of base control it was mixed in with. To handle undo
630 functionality, the ._SetValue() must record the current
631 selection prior to setting the value.
632
633 .Cut()
634 .Paste()
635 .Undo()
636 .SetValue() REQUIRED
637 Each class derived from MaskedEditMixin must redefine
638 these functions to call the _Cut(), _Paste(), _Undo()
639 and _SetValue() methods, respectively for the control,
640 so as to prevent programmatic corruption of the control's
641 value. This must be done in each derivation, as the
642 mixin cannot itself override a member of a sibling class.
643
644 ._Refresh() REQUIRED
645 Each class derived from MaskedEditMixin must define
646 the function used to refresh the base control.
647
648 .Refresh() REQUIRED
649 Each class derived from MaskedEditMixin must redefine
650 this function so that it checks the validity of the
651 control (via self._CheckValid) and then refreshes
652 control using the base class method.
653
654 ._IsEditable() REQUIRED
655 Each class derived from MaskedEditMixin must define
656 the function used to determine if the base control is
657 editable or not. (For masked.ComboBox, this has to
658 be done with code, rather than specifying the proper
659 function in the base control, as there isn't one...)
660 ._CalcSize() REQUIRED
661 Each class derived from MaskedEditMixin must define
662 the function used to determine how wide the control
663 should be given the mask. (The mixin function
664 ._calcSize() provides a baseline estimate.)
665
666
667 Event Handling
668 --------------
669 Event handlers are "chained", and MaskedEditMixin usually
670 swallows most of the events it sees, thereby preventing any other
671 handlers from firing in the chain. It is therefore required that
672 each class derivation using the mixin to have an option to hook up
673 the event handlers itself or forego this operation and let a
674 subclass of the masked control do so. For this reason, each
675 subclass should probably include the following code:
676
677 if setupEventHandling:
678 ## Setup event handlers
679 EVT_SET_FOCUS( self, self._OnFocus ) ## defeat automatic full selection
680 EVT_KILL_FOCUS( self, self._OnKillFocus ) ## run internal validator
681 EVT_LEFT_DCLICK(self, self._OnDoubleClick) ## select field under cursor on dclick
682 EVT_RIGHT_UP(self, self._OnContextMenu ) ## bring up an appropriate context menu
683 EVT_KEY_DOWN( self, self._OnKeyDown ) ## capture control events not normally seen, eg ctrl-tab.
684 EVT_CHAR( self, self._OnChar ) ## handle each keypress
685 EVT_TEXT( self, self.GetId(), self._OnTextChange ) ## color control appropriately & keep
686 ## track of previous value for undo
687
688 where setupEventHandling is an argument to its constructor.
689
690 These 5 handlers must be "wired up" for the masked edit
691 controls to provide default behavior. (The setupEventHandling
692 is an argument to masked.TextCtrl and masked.ComboBox, so
693 that controls derived from *them* may replace one of these
694 handlers if they so choose.)
695
696 If your derived control wants to preprocess events before
697 taking action, it should then set up the event handling itself,
698 so it can be first in the event handler chain.
699
700
701 The following routines are available to facilitate changing
702 the default behavior of masked edit controls:
703
704 ._SetKeycodeHandler(keycode, func)
705 ._SetKeyHandler(char, func)
706 Use to replace default handling for any given keycode.
707 func should take the key event as argument and return
708 False if no further action is required to handle the
709 key. Eg:
710 self._SetKeycodeHandler(WXK_UP, self.IncrementValue)
711 self._SetKeyHandler('-', self._OnChangeSign)
712
713 (Setting a func of None removes any keyhandler for the given key.)
714
715 "Navigation" keys are assumed to change the cursor position, and
716 therefore don't cause automatic motion of the cursor as insertable
717 characters do.
718
719 ._AddNavKeycode(keycode, handler=None)
720 ._AddNavKey(char, handler=None)
721 Allows controls to specify other keys (and optional handlers)
722 to be treated as navigational characters. (eg. '.' in IpAddrCtrl)
723
724 ._GetNavKeycodes() Returns the current list of navigational keycodes.
725
726 ._SetNavKeycodes(key_func_tuples)
727 Allows replacement of the current list of keycode
728 processed as navigation keys, and bind associated
729 optional keyhandlers. argument is a list of key/handler
730 tuples. Passing a value of None for the handler in a
731 given tuple indicates that default processing for the key
732 is desired.
733
734 ._FindField(pos) Returns the Field object associated with this position
735 in the control.
736
737 ._FindFieldExtent(pos, getslice=False, value=None)
738 Returns edit_start, edit_end of the field corresponding
739 to the specified position within the control, and
740 optionally also returns the current contents of that field.
741 If value is specified, it will retrieve the slice the corresponding
742 slice from that value, rather than the current value of the
743 control.
744
745 ._AdjustField(pos)
746 This is, the function that gets called for a given position
747 whenever the cursor is adjusted to leave a given field.
748 By default, it adjusts the year in date fields if mask is a date,
749 It can be overridden by a derived class to
750 adjust the value of the control at that time.
751 (eg. IpAddrCtrl reformats the address in this way.)
752
753 ._Change() Called by internal EVT_TEXT handler. Return False to force
754 skip of the normal class change event.
755 ._Keypress(key) Called by internal EVT_CHAR handler. Return False to force
756 skip of the normal class keypress event.
757 ._LostFocus() Called by internal EVT_KILL_FOCUS handler
758
759 ._OnKeyDown(event)
760 This is the default EVT_KEY_DOWN routine; it just checks for
761 "navigation keys", and if event.ControlDown(), it fires the
762 mixin's _OnChar() routine, as such events are not always seen
763 by the "cooked" EVT_CHAR routine.
764
765 ._OnChar(event) This is the main EVT_CHAR handler for the
766 MaskedEditMixin.
767
768 The following routines are used to handle standard actions
769 for control keys:
770 _OnArrow(event) used for arrow navigation events
771 _OnCtrl_A(event) 'select all'
772 _OnCtrl_C(event) 'copy' (uses base control function, as copy is non-destructive)
773 _OnCtrl_S(event) 'save' (does nothing)
774 _OnCtrl_V(event) 'paste' - calls _Paste() method, to do smart paste
775 _OnCtrl_X(event) 'cut' - calls _Cut() method, to "erase" selection
776 _OnCtrl_Z(event) 'undo' - resets value to previous value (if any)
777
778 _OnChangeField(event) primarily used for tab events, but can be
779 used for other keys (eg. '.' in IpAddrCtrl)
780
781 _OnErase(event) used for backspace and delete
782 _OnHome(event)
783 _OnEnd(event)
784
785 The following routine provides a hook back to any class derivations, so that
786 they can react to parameter changes before any value is set/reset as a result of
787 those changes. (eg. masked.ComboBox needs to detect when the choices list is
788 modified, either implicitly or explicitly, so it can reset the base control
789 to have the appropriate choice list *before* the initial value is reset to match.)
790
791 _OnCtrlParametersChanged()
792
793 Accessor Functions
794 ------------------
795 For convenience, each class derived from MaskedEditMixin should
796 define an accessors mixin, so that it exposes only those parameters
797 that make sense for the derivation. This is done with an intermediate
798 level of inheritance, ie:
799
800 class BaseMaskedTextCtrl( TextCtrl, MaskedEditMixin ):
801
802 class TextCtrl( BaseMaskedTextCtrl, MaskedEditAccessorsMixin ):
803 class ComboBox( BaseMaskedComboBox, MaskedEditAccessorsMixin ):
804 class NumCtrl( BaseMaskedTextCtrl, MaskedNumCtrlAccessorsMixin ):
805 class IpAddrCtrl( BaseMaskedTextCtrl, IpAddrCtrlAccessorsMixin ):
806 class TimeCtrl( BaseMaskedTextCtrl, TimeCtrlAccessorsMixin ):
807
808 etc.
809
810 Each accessors mixin defines Get/Set functions for the base class parameters
811 that are appropriate for that derivation.
812 This allows the base classes to be "more generic," exposing the widest
813 set of options, while not requiring derived classes to be so general.

6669 ## Current Issues:
6670 ## ===================================
6671 ##
6672 ## 1. WS: For some reason I don't understand, the control is generating two (2)
6673 ## EVT_TEXT events for every one (1) .SetValue() of the underlying control.
6674 ## I've been unsuccessful in determining why or in my efforts to make just one
6675 ## occur. So, I've added a hack to save the last seen value from the
6676 ## control in the EVT_TEXT handler, and if *different*, call event.Skip()
6677 ## to propagate it down the event chain, and let the application see it.
6678 ##
6679 ## 2. WS: MaskedComboBox is deficient in several areas, all having to do with the
6680 ## behavior of the underlying control that I can't fix. The problems are:
6681 ## a) The background coloring doesn't work in the text field of the control;
6682 ## instead, there's a only border around it that assumes the correct color.
6683 ## b) The control will not pass WXK_TAB to the event handler, no matter what
6684 ## I do, and there's no style wxCB_PROCESS_TAB like wxTE_PROCESS_TAB to
6685 ## indicate that we want these events. As a result, MaskedComboBox
6686 ## doesn't do the nice field-tabbing that MaskedTextCtrl does.
6687 ## c) Auto-complete had to be reimplemented for the control because programmatic
6688 ## setting of the value of the text field does not set up the auto complete
6689 ## the way that the control processing keystrokes does. (But I think I've
6690 ## implemented a fairly decent approximation.) Because of this the control
6691 ## also won't auto-complete on dropdown, and there's no event I can catch
6692 ## to work around this problem.
6693 ## d) There is no method provided for getting the selection; the hack I've
6694 ## implemented has its flaws, not the least of which is that due to the
6695 ## strategy that I'm using, the paste buffer is always replaced by the
6696 ## contents of the control's selection when in focus, on each keystroke;
6697 ## this makes it impossible to paste anything into a MaskedComboBox
6698 ## at the moment... :-(
6699 ## e) The other deficient behavior, likely induced by the workaround for (d),
6700 ## is that you can can't shift-left to select more than one character
6701 ## at a time.
6702 ##
6703 ##
6704 ## 3. WS: Controls on wxPanels don't seem to pass Shift-WXK_TAB to their
6705 ## EVT_KEY_DOWN or EVT_CHAR event handlers. Until this is fixed in
6706 ## wxWindows, shift-tab won't take you backwards through the fields of
6707 ## a MaskedTextCtrl like it should. Until then Shifted arrow keys will
6708 ## work like shift-tab and tab ought to.
6709 ##
6710
6711 ## To-Do's:
6712 ## =============================##
6713 ## 1. Add Popup list for auto-completable fields that simulates combobox on individual
6714 ## fields. Example: City validates against list of cities, or zip vs zip code list.
6715 ## 2. Allow optional monetary symbols (eg. $, pounds, etc.) at front of a "decimal"
6716 ## control.
6717 ## 3. Fix shift-left selection for MaskedComboBox.
6718 ## 5. Transform notion of "decimal control" to be less "entire control"-centric,
6719 ## so that monetary symbols can be included and still have the appropriate
6720 ## semantics. (Big job, as currently written, but would make control even
6721 ## more useful for business applications.)
6722
6723
6724 ## CHANGELOG:
6725 ## ====================
6726 ## Version 1.12
6727 ## 1. Added proper support for NUMPAD keypad keycodes for navigation and control.
6728 ##
6729 ## Version 1.11
6730 ## 1. Added value member to ValueError exceptions, so that people can catch them
6731 ## and then display their own errors, and added attribute raiseOnInvalidPaste,
6732 ## so one doesn't have to subclass the controls simply to force generation of
6733 ## a ValueError on a bad paste operation.
6734 ## 2. Fixed handling of unicode charsets by converting to explicit control char
6735 ## set testing for passing those keystrokes to the base control, and then
6736 ## changing the semantics of the * maskchar to indicate any visible char.
6737 ## 3. Added '|' mask specification character, which allows splitting of contiguous
6738 ## mask characters into separate fields, allowing finer control of behavior
6739 ## of a control.
6740 ##
6741 ##
6742 ## Version 1.10
6743 ## 1. Added handling for WXK_DELETE and WXK_INSERT, such that shift-delete
6744 ## cuts, shift-insert pastes, and ctrl-insert copies.
6745 ##
6746 ## Version 1.9
6747 ## 1. Now ignores kill focus events when being destroyed.
6748 ## 2. Added missing call to set insertion point on changing fields.
6749 ## 3. Modified SetKeyHandler() to accept None as means of removing one.
6750 ## 4. Fixed keyhandler processing for group and decimal character changes.
6751 ## 5. Fixed a problem that prevented input into the integer digit of a
6752 ## integerwidth=1 numctrl, if the current value was 0.
6753 ## 6. Fixed logic involving processing of "_signOk" flag, to remove default
6754 ## sign key handlers if false, so that SetAllowNegative(False) in the
6755 ## NumCtrl works properly.
6756 ## 7. Fixed selection logic for numeric controls so that if selectOnFieldEntry
6757 ## is true, and the integer portion of an integer format control is selected
6758 ## and the sign position is selected, the sign keys will always result in a
6759 ## negative value, rather than toggling the previous sign.
6760 ##
6761 ##
6762 ## Version 1.8
6763 ## 1. Fixed bug involving incorrect variable name, causing combobox autocomplete to fail.
6764 ## 2. Added proper support for unicode version of wxPython
6765 ## 3. Added * as mask char meaning "all ansi chars" (ordinals 32-255).
6766 ## 4. Converted doc strings to use reST format, for ePyDoc documentation.
6767 ## 5. Renamed helper functions, classes, etc. not intended to be visible in public
6768 ## interface to code.
6769 ##
6770 ## Version 1.7
6771 ## 1. Fixed intra-right-insert-field erase, such that it doesn't leave a hole, but instead
6772 ## shifts the text to the left accordingly.
6773 ## 2. Fixed _SetValue() to place cursor after last character inserted, rather than end of
6774 ## mask.
6775 ## 3. Fixed some incorrect undo behavior for right-insert fields, and allowed derived classes
6776 ## (eg. numctrl) to pass modified values for undo processing (to handle/ignore grouping
6777 ## chars properly.)
6778 ## 4. Fixed autoselect behavior to work similarly to (2) above, so that combobox
6779 ## selection will only select the non-empty text, as per request.
6780 ## 5. Fixed tabbing to work with 2.5.2 semantics.
6781 ## 6. Fixed size calculation to handle changing fonts
6782 ##
6783 ## Version 1.6
6784 ## 1. Reorganized masked controls into separate package, renamed things accordingly
6785 ## 2. Split actual controls out of this file into their own files.
6786 ## Version 1.5
6787 ## (Reported) bugs fixed:
6788 ## 1. Crash ensues if you attempt to change the mask of a read-only
6789 ## MaskedComboBox after initial construction.
6790 ## 2. Changed strategy of defining Get/Set property functions so that
6791 ## these are now generated dynamically at runtime, rather than as
6792 ## part of the class definition. (This makes it possible to have
6793 ## more general base classes that have many more options for configuration
6794 ## without requiring that derivations support the same options.)
6795 ## 3. Fixed IsModified for _Paste() and _OnErase().
6796 ##
6797 ## Enhancements:
6798 ## 1. Fixed "attribute function inheritance," since base control is more
6799 ## generic than subsequent derivations, not all property functions of a
6800 ## generic control should be exposed in those derivations. New strategy
6801 ## uses base control classes (eg. BaseMaskedTextCtrl) that should be
6802 ## used to derive new class types, and mixed with their own mixins to
6803 ## only expose those attributes from the generic masked controls that
6804 ## make sense for the derivation. (This makes Boa happier.)
6805 ## 2. Renamed (with b-c) MILTIME autoformats to 24HRTIME, so as to be less
6806 ## "parochial."
6807 ##
6808 ## Version 1.4
6809 ## (Reported) bugs fixed:
6810 ## 1. Right-click menu allowed "cut" operation that destroyed mask
6811 ## (was implemented by base control)
6812 ## 2. MaskedComboBox didn't allow .Append() of mixed-case values; all
6813 ## got converted to lower case.
6814 ## 3. MaskedComboBox selection didn't deal with spaces in values
6815 ## properly when autocompleting, and didn't have a concept of "next"
6816 ## match for handling choice list duplicates.
6817 ## 4. Size of MaskedComboBox was always default.
6818 ## 5. Email address regexp allowed some "non-standard" things, and wasn't
6819 ## general enough.
6820 ## 6. Couldn't easily reset MaskedComboBox contents programmatically.
6821 ## 7. Couldn't set emptyInvalid during construction.
6822 ## 8. Under some versions of wxPython, readonly comboboxes can apparently
6823 ## return a GetInsertionPoint() result (655535), causing masked control
6824 ## to fail.
6825 ## 9. Specifying an empty mask caused the controls to traceback.
6826 ## 10. Can't specify float ranges for validRange.
6827 ## 11. '.' from within a the static portion of a restricted IP address
6828 ## destroyed the mask from that point rightward; tab when cursor is
6829 ## before 1st field takes cursor past that field.
6830 ##
6831 ## Enhancements:
6832 ## 12. Added Ctrl-Z/Undo handling, (and implemented context-menu properly.)
6833 ## 13. Added auto-select option on char input for masked controls with
6834 ## choice lists.
6835 ## 14. Added '>' formatcode, allowing insert within a given or each field
6836 ## as appropriate, rather than requiring "overwrite". This makes single
6837 ## field controls that just have validation rules (eg. EMAIL) much more
6838 ## friendly. The same flag controls left shift when deleting vs just
6839 ## blanking the value, and for right-insert fields, allows right-insert
6840 ## at any non-blank (non-sign) position in the field.
6841 ## 15. Added option to use to indicate negative values for numeric controls.
6842 ## 16. Improved OnFocus handling of numeric controls.
6843 ## 17. Enhanced Home/End processing to allow operation on a field level,
6844 ## using ctrl key.
6845 ## 18. Added individual Get/Set functions for control parameters, for
6846 ## simplified integration with Boa Constructor.
6847 ## 19. Standardized "Colour" parameter names to match wxPython, with
6848 ## non-british spellings still supported for backward-compatibility.
6849 ## 20. Added '&' mask specification character for punctuation only (no letters
6850 ## or digits).
6851 ## 21. Added (in a separate file) wx.MaskedCtrl() factory function to provide
6852 ## unified interface to the masked edit subclasses.
6853 ##
6854 ##
6855 ## Version 1.3
6856 ## 1. Made it possible to configure grouping, decimal and shift-decimal characters,
6857 ## to make controls more usable internationally.
6858 ## 2. Added code to smart "adjust" value strings presented to .SetValue()
6859 ## for right-aligned numeric format controls if they are shorter than
6860 ## than the control width, prepending the missing portion, prepending control
6861 ## template left substring for the missing characters, so that setting
6862 ## numeric values is easier.
6863 ## 3. Renamed SetMaskParameters SetCtrlParameters() (with old name preserved
6864 ## for b-c), as this makes more sense.
6865 ##
6866 ## Version 1.2
6867 ## 1. Fixed .SetValue() to replace the current value, rather than the current
6868 ## selection. Also changed it to generate ValueError if presented with
6869 ## either a value which doesn't follow the format or won't fit. Also made
6870 ## set value adjust numeric and date controls as if user entered the value.
6871 ## Expanded doc explaining how SetValue() works.
6872 ## 2. Fixed EUDATE* autoformats, fixed IsDateType mask list, and added ability to
6873 ## use 3-char months for dates, and EUDATETIME, and EUDATEMILTIME autoformats.
6874 ## 3. Made all date autoformats automatically pick implied "datestyle".
6875 ## 4. Added IsModified override, since base wx.TextCtrl never reports modified if
6876 ## .SetValue used to change the value, which is what the masked edit controls
6877 ## use internally.
6878 ## 5. Fixed bug in date position adjustment on 2 to 4 digit date conversion when
6879 ## using tab to "leave field" and auto-adjust.
6880 ## 6. Fixed bug in _isCharAllowed() for negative number insertion on pastes,
6881 ## and bug in ._Paste() that didn't account for signs in signed masks either.
6882 ## 7. Fixed issues with _adjustPos for right-insert fields causing improper
6883 ## selection/replacement of values
6884 ## 8. Fixed _OnHome handler to properly handle extending current selection to
6885 ## beginning of control.
6886 ## 9. Exposed all (valid) autoformats to demo, binding descriptions to
6887 ## autoformats.
6888 ## 10. Fixed a couple of bugs in email regexp.
6889 ## 11. Made maskchardict an instance var, to make mask chars to be more
6890 ## amenable to international use.
6891 ## 12. Clarified meaning of '-' formatcode in doc.
6892 ## 13. Fixed a couple of coding bugs being flagged by Python2.1.
6893 ## 14. Fixed several issues with sign positioning, erasure and validity
6894 ## checking for "numeric" masked controls.
6895 ## 15. Added validation to IpAddrCtrl.SetValue().
6896 ##
6897 ## Version 1.1
6898 ## 1. Changed calling interface to use boolean "useFixedWidthFont" (True by default)
6899 ## vs. literal font facename, and use wxTELETYPE as the font family
6900 ## if so specified.
6901 ## 2. Switched to use of dbg module vs. locally defined version.
6902 ## 3. Revamped entire control structure to use Field classes to hold constraint
6903 ## and formatting data, to make code more hierarchical, allow for more
6904 ## sophisticated masked edit construction.
6905 ## 4. Better strategy for managing options, and better validation on keywords.
6906 ## 5. Added 'V' format code, which requires that in order for a character
6907 ## to be accepted, it must result in a string that passes the validRegex.
6908 ## 6. Added 'S' format code which means "select entire field when navigating
6909 ## to new field."
6910 ## 7. Added 'r' format code to allow "right-insert" fields. (implies 'R'--right-alignment)
6911 ## 8. Added '<' format code to allow fields to require explicit cursor movement
6912 ## to leave field.
6913 ## 9. Added validFunc option to other validation mechanisms, that allows derived
6914 ## classes to add dynamic validation constraints to the control.
6915 ## 10. Fixed bug in validatePaste code causing possible IndexErrors, and also
6916 ## fixed failure to obey case conversion codes when pasting.
6917 ## 11. Implemented '0' (zero-pad) formatting code, as it wasn't being done anywhere...
6918 ## 12. Removed condition from OnDecimalPoint, so that it always truncates right on '.'
6919 ## 13. Enhanced IpAddrCtrl to use right-insert fields, selection on field traversal,
6920 ## individual field validation to prevent field values > 255, and require explicit
6921 ## tab/. to change fields.
6922 ## 14. Added handler for left double-click to select field under cursor.
6923 ## 15. Fixed handling for "Read-only" styles.
6924 ## 16. Separated signedForegroundColor from 'R' style, and added foregroundColor
6925 ## attribute, for more consistent and controllable coloring.
6926 ## 17. Added retainFieldValidation parameter, allowing top-level constraints
6927 ## such as "validRequired" to be set independently of field-level equivalent.
6928 ## (needed in TimeCtrl for bounds constraints.)
6929 ## 18. Refactored code a bit, cleaned up and commented code more heavily, fixed
6930 ## some of the logic for setting/resetting parameters, eg. fillChar, defaultValue,
6931 ## etc.
6932 ## 19. Fixed maskchar setting for upper/lowercase, to work in all locales.
6933 ##
6934 ##
6935 ## Version 1.0
6936 ## 1. Decimal point behavior restored for decimal and integer type controls:
6937 ## decimal point now trucates the portion > 0.
6938 ## 2. Return key now works like the tab character and moves to the next field,
6939 ## provided no default button is set for the form panel on which the control
6940 ## resides.
6941 ## 3. Support added in _FindField() for subclasses controls (like timecontrol)
6942 ## to determine where the current insertion point is within the mask (i.e.
6943 ## which sub-'field'). See method documentation for more info and examples.
6944 ## 4. Added Field class and support for all constraints to be field-specific
6945 ## in addition to being globally settable for the control.
6946 ## Choices for each field are validated for length and pastability into
6947 ## the field in question, raising ValueError if not appropriate for the control.
6948 ## Also added selective additional validation based on individual field constraints.
6949 ## By default, SHIFT-WXK_DOWN, SHIFT-WXK_UP, WXK_PRIOR and WXK_NEXT all
6950 ## auto-complete fields with choice lists, supplying the 1st entry in
6951 ## the choice list if the field is empty, and cycling through the list in
6952 ## the appropriate direction if already a match. WXK_DOWN will also auto-
6953 ## complete if the field is partially completed and a match can be made.
6954 ## SHIFT-WXK_UP/DOWN will also take you to the next field after any
6955 ## auto-completion performed.
6956 ## 5. Added autoCompleteKeycodes=[] parameters for allowing further
6957 ## customization of the control. Any keycode supplied as a member
6958 ## of the _autoCompleteKeycodes list will be treated like WXK_NEXT. If
6959 ## requireFieldChoice is set, then a valid value from each non-empty
6960 ## choice list will be required for the value of the control to validate.
6961 ## 6. Fixed "auto-sizing" to be relative to the font actually used, rather
6962 ## than making assumptions about character width.
6963 ## 7. Fixed GetMaskParameter(), which was non-functional in previous version.
6964 ## 8. Fixed exceptions raised to provide info on which control had the error.
6965 ## 9. Fixed bug in choice management of MaskedComboBox.
6966 ## 10. Fixed bug in IpAddrCtrl causing traceback if field value was of
6967 ## the form '# #'. Modified control code for IpAddrCtrl so that '.'
6968 ## in the middle of a field clips the rest of that field, similar to
6969 ## decimal and integer controls.
6970 ##
6971 ##
6972 ## Version 0.0.7
6973 ## 1. "-" is a toggle for sign; "+" now changes - signed numerics to positive.
6974 ## 2. ',' in formatcodes now causes numeric values to be comma-delimited (e.g.333,333).
6975 ## 3. New support for selecting text within the control.(thanks Will Sadkin!)
6976 ## Shift-End and Shift-Home now select text as you would expect
6977 ## Control-Shift-End selects to the end of the mask string, even if value not entered.
6978 ## Control-A selects all *entered* text, Shift-Control-A selects everything in the control.
6979 ## 4. event.Skip() added to onKillFocus to correct remnants when running in Linux (contributed-
6980 ## for some reason I couldn't find the original email but thanks!!!)
6981 ## 5. All major key-handling code moved to their own methods for easier subclassing: OnHome,
6982 ## OnErase, OnEnd, OnCtrl_X, OnCtrl_A, etc.
6983 ## 6. Email and autoformat validations corrected using regex provided by Will Sadkin (thanks!).
6984 ## (The rest of the changes in this version were done by Will Sadkin with permission from Jeff...)
6985 ## 7. New mechanism for replacing default behavior for any given key, using
6986 ## ._SetKeycodeHandler(keycode, func) and ._SetKeyHandler(char, func) now available
6987 ## for easier subclassing of the control.
6988 ## 8. Reworked the delete logic, cut, paste and select/replace logic, as well as some bugs
6989 ## with insertion point/selection modification. Changed Ctrl-X to use standard "cut"
6990 ## semantics, erasing the selection, rather than erasing the entire control.
6991 ## 9. Added option for an "default value" (ie. the template) for use when a single fillChar
6992 ## is not desired in every position. Added IsDefault() function to mean "does the value
6993 ## equal the template?" and modified .IsEmpty() to mean "do all of the editable
6994 ## positions in the template == the fillChar?"
6995 ## 10. Extracted mask logic into mixin, so we can have both MaskedTextCtrl and MaskedComboBox,
6996 ## now included.
6997 ## 11. MaskedComboBox now adds the capability to validate from list of valid values.
6998 ## Example: City validates against list of cities, or zip vs zip code list.
6999 ## 12. Fixed oversight in EVT_TEXT handler that prevented the events from being
7000 ## passed to the next handler in the event chain, causing updates to the
7001 ## control to be invisible to the parent code.
7002 ## 13. Added IPADDR autoformat code, and subclass IpAddrCtrl for controlling tabbing within
7003 ## the control, that auto-reformats as you move between cells.
7004 ## 14. Mask characters [A,a,X,#] can now appear in the format string as literals, by using '\'.
7005 ## 15. It is now possible to specify repeating masks, e.g. #{3}-#{3}-#{14}
7006 ## 16. Fixed major bugs in date validation, due to the fact that
7007 ## wxDateTime.ParseDate is too liberal, and will accept any form that
7008 ## makes any kind of sense, regardless of the datestyle you specified
7009 ## for the control. Unfortunately, the strategy used to fix it only
7010 ## works for versions of wxPython post 2.3.3.1, as a C++ assert box
7011 ## seems to show up on an invalid date otherwise, instead of a catchable
7012 ## exception.
7013 ## 17. Enhanced date adjustment to automatically adjust heuristic based on
7014 ## current year, making last century/this century determination on
7015 ## 2-digit year based on distance between today's year and value;
7016 ## if > 50 year separation, assume last century (and don't assume last
7017 ## century is 20th.)
7018 ## 18. Added autoformats and support for including HHMMSS as well as HHMM for
7019 ## date times, and added similar time, and militaray time autoformats.
7020 ## 19. Enhanced tabbing logic so that tab takes you to the next field if the
7021 ## control is a multi-field control.
7022 ## 20. Added stub method called whenever the control "changes fields", that
7023 ## can be overridden by subclasses (eg. IpAddrCtrl.)
7024 ## 21. Changed a lot of code to be more functionally-oriented so side-effects
7025 ## aren't as problematic when maintaining code and/or adding features.
7026 ## Eg: IsValid() now does not have side-effects; it merely reflects the
7027 ## validity of the value of the control; to determine validity AND recolor
7028 ## the control, _CheckValid() should be used with a value argument of None.
7029 ## Similarly, made most reformatting function take an optional candidate value
7030 ## rather than just using the current value of the control, and only
7031 ## have them change the value of the control if a candidate is not specified.
7032 ## In this way, you can do validation *before* changing the control.
7033 ## 22. Changed validRequired to mean "disallow chars that result in invalid
7034 ## value." (Old meaning now represented by emptyInvalid.) (This was
7035 ## possible once I'd made the changes in (19) above.)
7036 ## 23. Added .SetMaskParameters and .GetMaskParameter methods, so they
7037 ## can be set/modified/retrieved after construction. Removed individual
7038 ## parameter setting functions, in favor of this mechanism, so that
7039 ## all adjustment of the control based on changing parameter values can
7040 ## be handled in one place with unified mechanism.
7041 ## 24. Did a *lot* of testing and fixing re: numeric values. Added ability
7042 ## to type "grouping char" (ie. ',') and validate as appropriate.
7043 ## 25. Fixed ZIPPLUS4 to allow either 5 or 4, but if > 5 must be 9.
7044 ## 26. Fixed assumption about "decimal or integer" masks so that they're only
7045 ## made iff there's no validRegex associated with the field. (This
7046 ## is so things like zipcodes which look like integers can have more
7047 ## restrictive validation (ie. must be 5 digits.)
7048 ## 27. Added a ton more doc strings to explain use and derivation requirements
7049 ## and did regularization of the naming conventions.
7050 ## 28. Fixed a range bug in _adjustKey preventing z from being handled properly.
7051 ## 29. Changed behavior of '.' (and shift-.) in numeric controls to move to
7052 ## reformat the value and move the next field as appropriate. (shift-'.',
7053 ## ie. '>' moves to the previous field.
7054
7055 ## Version 0.0.6
7056 ## 1. Fixed regex bug that caused autoformat AGE to invalidate any age ending
7057 ## in '0'.
7058 ## 2. New format character 'D' to trigger date type. If the user enters 2 digits in the
7059 ## year position, the control will expand the value to four digits, using numerals below
7060 ## 50 as 21st century (20+nn) and less than 50 as 20th century (19+nn).
7061 ## Also, new optional parameter datestyle = set to one of {MDY|DMY|YDM}
7062 ## 3. revalid parameter renamed validRegex to conform to standard for all validation
7063 ## parameters (see 2 new ones below).
7064 ## 4. New optional init parameter = validRange. Used only for int/dec (numeric) types.
7065 ## Allows the developer to specify a valid low/high range of values.
7066 ## 5. New optional init parameter = validList. Used for character types. Allows developer
7067 ## to send a list of values to the control to be used for specific validation.
7068 ## See the Last Name Only example - it is list restricted to Smith/Jones/Williams.
7069 ## 6. Date type fields now use wxDateTime's parser to validate the date and time.
7070 ## This works MUCH better than my kludgy regex!! Thanks to Robin Dunn for pointing
7071 ## me toward this solution!
7072 ## 7. Date fields now automatically expand 2-digit years when it can. For example,
7073 ## if the user types "03/10/67", then "67" will auto-expand to "1967". If a two-year
7074 ## date is entered it will be expanded in any case when the user tabs out of the
7075 ## field.
7076 ## 8. New class functions: SetValidBackgroundColor, SetInvalidBackgroundColor, SetEmptyBackgroundColor,
7077 ## SetSignedForeColor allow accessto override default class coloring behavior.
7078 ## 9. Documentation updated and improved.
7079 ## 10. Demo - page 2 is now a wxFrame class instead of a wxPyApp class. Works better.
7080 ## Two new options (checkboxes) - test highlight empty and disallow empty.
7081 ## 11. Home and End now work more intuitively, moving to the first and last user-entry
7082 ## value, respectively.
7083 ## 12. New class function: SetRequired(bool). Sets the control's entry required flag
7084 ## (i.e. disallow empty values if True).
7085 ##
7086 ## Version 0.0.5
7087 ## 1. get_plainValue method renamed to GetPlainValue following the wxWindows
7088 ## StudlyCaps(tm) standard (thanks Paul Moore). ;)
7089 ## 2. New format code 'F' causes the control to auto-fit (auto-size) itself
7090 ## based on the length of the mask template.
7091 ## 3. Class now supports "autoformat" codes. These can be passed to the class
7092 ## on instantiation using the parameter autoformat="code". If the code is in
7093 ## the dictionary, it will self set the mask, formatting, and validation string.
7094 ## I have included a number of samples, but I am hoping that someone out there
7095 ## can help me to define a whole bunch more.
7096 ## 4. I have added a second page to the demo (as well as a second demo class, test2)
7097 ## to showcase how autoformats work. The way they self-format and self-size is,
7098 ## I must say, pretty cool.
7099 ## 5. Comments added and some internal cosmetic revisions re: matching the code
7100 ## standards for class submission.
7101 ## 6. Regex validation is now done in real time - field turns yellow immediately
7102 ## and stays yellow until the entered value is valid
7103 ## 7. Cursor now skips over template characters in a more intuitive way (before the
7104 ## next keypress).
7105 ## 8. Change, Keypress and LostFocus methods added for convenience of subclasses.
7106 ## Developer may use these methods which will be called after EVT_TEXT, EVT_CHAR,
7107 ## and EVT_KILL_FOCUS, respectively.
7108 ## 9. Decimal and numeric handlers have been rewritten and now work more intuitively.
7109 ##
7110 ## Version 0.0.4
7111 ## 1. New .IsEmpty() method returns True if the control's value is equal to the
7112 ## blank template string
7113 ## 2. Control now supports a new init parameter: revalid. Pass a regular expression
7114 ## that the value will have to match when the control loses focus. If invalid,
7115 ## the control's BackgroundColor will turn yellow, and an internal flag is set (see next).
7116 ## 3. Demo now shows revalid functionality. Try entering a partial value, such as a
7117 ## partial social security number.
7118 ## 4. New .IsValid() value returns True if the control is empty, or if the value matches
7119 ## the revalid expression. If not, .IsValid() returns False.
7120 ## 5. Decimal values now collapse to decimal with '.00' on losefocus if the user never
7121 ## presses the decimal point.
7122 ## 6. Cursor now goes to the beginning of the field if the user clicks in an
7123 ## "empty" field intead of leaving the insertion point in the middle of the
7124 ## field.
7125 ## 7. New "N" mask type includes upper and lower chars plus digits. a-zA-Z0-9.
7126 ## 8. New formatcodes init parameter replaces other init params and adds functions.
7127 ## String passed to control on init controls:
7128 ## _ Allow spaces
7129 ## ! Force upper
7130 ## ^ Force lower
7131 ## R Show negative #s in red
7132 ## , Group digits
7133 ## - Signed numerals
7134 ## 0 Numeric fields get leading zeros
7135 ## 9. Ctrl-X in any field clears the current value.
7136 ## 10. Code refactored and made more modular (esp in OnChar method). Should be more
7137 ## easy to read and understand.
7138 ## 11. Demo enhanced.
7139 ## 12. Now has _doc_.
7140 ##
7141 ## Version 0.0.3
7142 ## 1. GetPlainValue() now returns the value without the template characters;
7143 ## so, for example, a social security number (123-33-1212) would return as
7144 ## 123331212; also removes white spaces from numeric/decimal values, so
7145 ## "- 955.32" is returned "-955.32". Press ctrl-S to see the plain value.
7146 ## 2. Press '.' in an integer style masked control and truncate any trailing digits.
7147 ## 3. Code moderately refactored. Internal names improved for clarity. Additional
7148 ## internal documentation.
7149 ## 4. Home and End keys now supported to move cursor to beginning or end of field.
7150 ## 5. Un-signed integers and decimals now supported.
7151 ## 6. Cosmetic improvements to the demo.
