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.

54 ====================
55 Masked Edit Overview
56 ====================
57
58 masked.TextCtrl:
59 is a sublassed text control that can carefully control the user's input
60 based on a mask string you provide.
61
62 General usage example::
63
64 control = masked.TextCtrl( win, -1, '', mask = '(###) ###-####')
65
66 The example above will create a text control that allows only numbers to be
67 entered and then only in the positions indicated in the mask by the # sign.
68
69 masked.ComboBox:
70 is a similar subclass of wxComboBox that allows the same sort of masking,
71 but also can do auto-complete of values, and can require the value typed
72 to be in the list of choices to be colored appropriately.
73
74 masked.Ctrl:
75 is actually a factory function for several types of masked edit controls:
76
77 ================= ==================================================
78 masked.TextCtrl standard masked edit text box
79 masked.ComboBox adds combobox capabilities
80 masked.IpAddrCtrl adds special semantics for IP address entry
81 masked.TimeCtrl special subclass handling lots of types as values
82 masked.NumCtrl special subclass handling numeric values
83 ================= ==================================================
84
85 It works by looking for a *controlType* parameter in the keyword
86 arguments of the control, to determine what kind of instance to return.
87 If not specified as a keyword argument, the default control type returned
88 will be masked.TextCtrl.
89
90 Each of the above classes has its own set of arguments, but masked.Ctrl
91 provides a single "unified" interface for masked controls. Those for
92 masked.TextCtrl, masked.ComboBox and masked.IpAddrCtrl are all documented
93 below; the others have their own demo pages and interface descriptions.
94 (See end of following discussion for how to configure the wx.MaskedCtrl()
95 to select the above control types.)
96
97 =========================
98
99 Initialization Parameters
100 -------------------------
101 mask
102 Allowed mask characters and function:
103
104 ========= ==========================================================
105 Character Function
106 ========= ==========================================================
107 # Allow numeric only (0-9)
108 N Allow letters and numbers (0-9)
109 A Allow uppercase letters only
110 a Allow lowercase letters only
111 C Allow any letter, upper or lower
112 X Allow string.letters, string.punctuation, string.digits
113 & Allow string.punctuation only
114 \* Allow any ansi character
115 ========= ==========================================================
116
117
118 These controls define these sets of characters using string.letters,
119 string.uppercase, etc. These sets are affected by the system locale
120 setting, so in order to have the masked controls accept characters
121 that are specific to your users' language, your application should
122 set the locale.
123 For example, to allow international characters to be used in the
124 above masks, you can place the following in your code as part of
125 your application's initialization code::
126
127 import locale
128 locale.setlocale(locale.LC_ALL, '')
129
130 The controls now also support (by popular demand) all "ansi" chars,
131 that is, all ascii codes between 32 and 255, by use of the * mask character.
132
133 Using these mask characters, a variety of template masks can be built. See
134 the demo for some other common examples include date+time, social security
135 number, etc. If any of these characters are needed as template rather
136 than mask characters, they can be escaped with \, ie. \N means "literal N".
137 (use \\ for literal backslash, as in: r'CCC\\NNN'.)
138
139
140 *Note:*
141 Masks containing only # characters and one optional decimal point
142 character are handled specially, as "numeric" controls. Such
143 controls have special handling for typing the '-' key, handling
144 the "decimal point" character as truncating the integer portion,
145 optionally allowing grouping characters and so forth.
146 There are several parameters and format codes that only make sense
147 when combined with such masks, eg. groupChar, decimalChar, and so
148 forth (see below). These allow you to construct reasonable
149 numeric entry controls.
150
151 *Note:*
152 Changing the mask for a control deletes any previous field classes
153 (and any associated validation or formatting constraints) for them.
154
155 useFixedWidthFont
156 By default, masked edit controls use a fixed width font, so that
157 the mask characters are fixed within the control, regardless of
158 subsequent modifications to the value. Set to False if having
159 the control font be the same as other controls is required. (This is
160 a control-level parameter.)
161
162 defaultEncoding
163 (Applies to unicode systems only) By default, the default unicode encoding
164 used is latin1, or iso-8859-1. If necessary, you can set this control-level
165 parameter to govern the codec used to decode your keyboard inputs.
166 (This is a control-level parameter.)
167
168 formatcodes
169 These other properties can be passed to the class when instantiating it:
170 Formatcodes are specified as a string of single character formatting
171 codes that modify behavior of the control::
172
173 _ Allow spaces
174 ! Force upper
175 ^ Force lower
176 R Right-align field(s)
177 r Right-insert in field(s) (implies R)
178 < Stay in field until explicit navigation out of it
179
180 > Allow insert/delete within partially filled fields (as
181 opposed to the default "overwrite" mode for fixed-width
182 masked edit controls.) This allows single-field controls
183 or each field within a multi-field control to optionally
184 behave more like standard text controls.
185 (See EMAIL or phone number autoformat examples.)
186
187 *Note: This also governs whether backspace/delete operations
188 shift contents of field to right of cursor, or just blank the
189 erased section.
190
191 Also, when combined with 'r', this indicates that the field
192 or control allows right insert anywhere within the current
193 non-empty value in the field. (Otherwise right-insert behavior
194 is only performed to when the entire right-insertable field is
195 selected or the cursor is at the right edge of the field.*
196
197
198 , Allow grouping character in integer fields of numeric controls
199 and auto-group/regroup digits (if the result fits) when leaving
200 such a field. (If specified, .SetValue() will attempt to
201 auto-group as well.)
202 ',' is also the default grouping character. To change the
203 grouping character and/or decimal character, use the groupChar
204 and decimalChar parameters, respectively.
205 Note: typing the "decimal point" character in such fields will
206 clip the value to that left of the cursor for integer
207 fields of controls with "integer" or "floating point" masks.
208 If the ',' format code is specified, this will also cause the
209 resulting digits to be regrouped properly, using the current
210 grouping character.
211 - Prepend and reserve leading space for sign to mask and allow
212 signed values (negative #s shown in red by default.) Can be
213 used with argument useParensForNegatives (see below.)
214 0 integer fields get leading zeros
215 D Date[/time] field
216 T Time field
217 F Auto-Fit: the control calulates its size from
218 the length of the template mask
219 V validate entered chars against validRegex before allowing them
220 to be entered vs. being allowed by basic mask and then having
221 the resulting value just colored as invalid.
222 (See USSTATE autoformat demo for how this can be used.)
223 S select entire field when navigating to new field
224
225 fillChar
226
227 defaultValue
228 These controls have two options for the initial state of the control.
229 If a blank control with just the non-editable characters showing
230 is desired, simply leave the constructor variable fillChar as its
231 default (' '). If you want some other character there, simply
232 change the fillChar to that value. Note: changing the control's fillChar
233 will implicitly reset all of the fields' fillChars to this value.
234
235 If you need different default characters in each mask position,
236 you can specify a defaultValue parameter in the constructor, or
237 set them for each field individually.
238 This value must satisfy the non-editable characters of the mask,
239 but need not conform to the replaceable characters.
240
241 groupChar
242
243 decimalChar
244 These parameters govern what character is used to group numbers
245 and is used to indicate the decimal point for numeric format controls.
246 The default groupChar is ',', the default decimalChar is '.'
247 By changing these, you can customize the presentation of numbers
248 for your location.
249
250 Eg::
251
252 formatcodes = ',', groupChar='\'' allows 12'345.34
253 formatcodes = ',', groupChar='.', decimalChar=',' allows 12.345,34
254
255 (These are control-level parameters.)
256
257 shiftDecimalChar
258 The default "shiftDecimalChar" (used for "backwards-tabbing" until
259 shift-tab is fixed in wxPython) is '>' (for QUERTY keyboards.) for
260 other keyboards, you may want to customize this, eg '?' for shift ',' on
261 AZERTY keyboards, ':' or ';' for other European keyboards, etc.
262 (This is a control-level parameter.)
263
264 useParensForNegatives=False
265 This option can be used with signed numeric format controls to
266 indicate signs via () rather than '-'.
267 (This is a control-level parameter.)
268
269 autoSelect=False
270 This option can be used to have a field or the control try to
271 auto-complete on each keystroke if choices have been specified.
272
273 autoCompleteKeycodes=[]
274 By default, DownArrow, PageUp and PageDown will auto-complete a
275 partially entered field. Shift-DownArrow, Shift-UpArrow, PageUp
276 and PageDown will also auto-complete, but if the field already
277 contains a matched value, these keys will cycle through the list
278 of choices forward or backward as appropriate. Shift-Up and
279 Shift-Down also take you to the next/previous field after any
280 auto-complete action.
281
282 Additional auto-complete keys can be specified via this parameter.
283 Any keys so specified will act like PageDown.
284 (This is a control-level parameter.)
285
286
287
288 Validating User Input
289 =====================
290 There are a variety of initialization parameters that are used to validate
291 user input. These parameters can apply to the control as a whole, and/or
292 to individual fields:
293
294 ===================== ==================================================================
295 excludeChars A string of characters to exclude even if otherwise allowed
296 includeChars A string of characters to allow even if otherwise disallowed
297 validRegex Use a regular expression to validate the contents of the text box
298 validRange Pass a rangeas list (low,high) to limit numeric fields/values
299 choices A list of strings that are allowed choices for the control.
300 choiceRequired value must be member of choices list
301 compareNoCase Perform case-insensitive matching when validating against list
302 *Note: for masked.ComboBox, this defaults to True.*
303 emptyInvalid Boolean indicating whether an empty value should be considered
304 invalid
305
306 validFunc A function to call of the form: bool = func(candidate_value)
307 which will return True if the candidate_value satisfies some
308 external criteria for the control in addition to the the
309 other validation, or False if not. (This validation is
310 applied last in the chain of validations.)
311
312 validRequired Boolean indicating whether or not keys that are allowed by the
313 mask, but result in an invalid value are allowed to be entered
314 into the control. Setting this to True implies that a valid
315 default value is set for the control.
316
317 retainFieldValidation False by default; if True, this allows individual fields to
318 retain their own validation constraints independently of any
319 subsequent changes to the control's overall parameters.
320 (This is a control-level parameter.)
321
322 validator Validators are not normally needed for masked controls, because
323 of the nature of the validation and control of input. However,
324 you can supply one to provide data transfer routines for the
325 controls.
326 ===================== ==================================================================
327
328
329 Coloring Behavior
330 =================
331 The following parameters have been provided to allow you to change the default
332 coloring behavior of the control. These can be set at construction, or via
333 the .SetCtrlParameters() function. Pass a color as string e.g. 'Yellow':
334
335 ======================== =======================================================================
336 emptyBackgroundColour Control Background color when identified as empty. Default=White
337 invalidBackgroundColour Control Background color when identified as Not valid. Default=Yellow
338 validBackgroundColour Control Background color when identified as Valid. Default=white
339 ======================== =======================================================================
340
341
342 The following parameters control the default foreground color coloring behavior of the
343 control. Pass a color as string e.g. 'Yellow':
344
345 ======================== ======================================================================
346 foregroundColour Control foreground color when value is not negative. Default=Black
347 signedForegroundColour Control foreground color when value is negative. Default=Red
348 ======================== ======================================================================
349
350
351 Fields
352 ======
353 Each part of the mask that allows user input is considered a field. The fields
354 are represented by their own class instances. You can specify field-specific
355 constraints by constructing or accessing the field instances for the control
356 and then specifying those constraints via parameters.
357
358 fields
359 This parameter allows you to specify Field instances containing
360 constraints for the individual fields of a control, eg: local
361 choice lists, validation rules, functions, regexps, etc.
362 It can be either an ordered list or a dictionary. If a list,
363 the fields will be applied as fields 0, 1, 2, etc.
364 If a dictionary, it should be keyed by field index.
365 the values should be a instances of maskededit.Field.
366
367 Any field not represented by the list or dictionary will be
368 implicitly created by the control.
369
370 Eg::
371
372 fields = [ Field(formatcodes='_r'), Field('choices=['a', 'b', 'c']) ]
373
374 Or::
375
376 fields = {
377 1: ( Field(formatcodes='_R', choices=['a', 'b', 'c']),
378 3: ( Field(choices=['01', '02', '03'], choiceRequired=True)
379 }
380
381 The following parameters are available for individual fields, with the
382 same semantics as for the whole control but applied to the field in question:
383
384 ============== =============================================================================
385 fillChar if set for a field, it will override the control's fillChar for that field
386 groupChar if set for a field, it will override the control's default
387 defaultValue sets field-specific default value; overrides any default from control
388 compareNoCase overrides control's settings
389 emptyInvalid determines whether field is required to be filled at all times
390 validRequired if set, requires field to contain valid value
391 ============== =============================================================================
392
393 If any of the above parameters are subsequently specified for the control as a
394 whole, that new value will be propagated to each field, unless the
395 retainFieldValidation control-level parameter is set.
396
397 ============== ==============================
398 formatcodes Augments control's settings
399 excludeChars ' ' '
400 includeChars ' ' '
401 validRegex ' ' '
402 validRange ' ' '
403 choices ' ' '
404 choiceRequired ' ' '
405 validFunc ' ' '
406 ============== ==============================
407
408
409
410 Control Class Functions
411 =======================
412 .GetPlainValue(value=None)
413 Returns the value specified (or the control's text value
414 not specified) without the formatting text.
415 In the example above, might return phone no='3522640075',
416 whereas control.GetValue() would return '(352) 264-0075'
417 .ClearValue()
418 Returns the control's value to its default, and places the
419 cursor at the beginning of the control.
420 .SetValue()
421 Does "smart replacement" of passed value into the control, as does
422 the .Paste() method. As with other text entry controls, the
423 .SetValue() text replacement begins at left-edge of the control,
424 with missing mask characters inserted as appropriate.
425 .SetValue will also adjust integer, float or date mask entry values,
426 adding commas, auto-completing years, etc. as appropriate.
427 For "right-aligned" numeric controls, it will also now automatically
428 right-adjust any value whose length is less than the width of the
429 control before attempting to set the value.
430 If a value does not follow the format of the control's mask, or will
431 not fit into the control, a ValueError exception will be raised.
432
433 Eg::
434
435 mask = '(###) ###-####'
436 .SetValue('1234567890') => '(123) 456-7890'
437 .SetValue('(123)4567890') => '(123) 456-7890'
438 .SetValue('(123)456-7890') => '(123) 456-7890'
439 .SetValue('123/4567-890') => illegal paste; ValueError
440
441 mask = '#{6}.#{2}', formatcodes = '_,-',
442 .SetValue('111') => ' 111 . '
443 .SetValue(' %9.2f' % -111.12345 ) => ' -111.12'
444 .SetValue(' %9.2f' % 1234.00 ) => ' 1,234.00'
445 .SetValue(' %9.2f' % -1234567.12345 ) => insufficient room; ValueError
446
447 mask = '#{6}.#{2}', formatcodes = '_,-R' # will right-adjust value for right-aligned control
448 .SetValue('111') => padded value misalignment ValueError: " 111" will not fit
449 .SetValue('%.2f' % 111 ) => ' 111.00'
450 .SetValue('%.2f' % -111.12345 ) => ' -111.12'
451
452
453 .IsValid(value=None)
454 Returns True if the value specified (or the value of the control
455 if not specified) passes validation tests
456 .IsEmpty(value=None)
457 Returns True if the value specified (or the value of the control
458 if not specified) is equal to an "empty value," ie. all
459 editable characters == the fillChar for their respective fields.
460 .IsDefault(value=None)
461 Returns True if the value specified (or the value of the control
462 if not specified) is equal to the initial value of the control.
463
464 .Refresh()
465 Recolors the control as appropriate to its current settings.
466
467 .SetCtrlParameters(\*\*kwargs)
468 This function allows you to set up and/or change the control parameters
469 after construction; it takes a list of key/value pairs as arguments,
470 where the keys can be any of the mask-specific parameters in the constructor.
471
472 Eg::
473
474 ctl = masked.TextCtrl( self, -1 )
475 ctl.SetCtrlParameters( mask='###-####',
476 defaultValue='555-1212',
477 formatcodes='F')
478
479 .GetCtrlParameter(parametername)
480 This function allows you to retrieve the current value of a parameter
481 from the control.
482
483 *Note:* Each of the control parameters can also be set using its
484 own Set and Get function. These functions follow a regular form:
485 All of the parameter names start with lower case; for their
486 corresponding Set/Get function, the parameter name is capitalized.
487
488 Eg::
489
490 ctl.SetMask('###-####')
491 ctl.SetDefaultValue('555-1212')
492 ctl.GetChoiceRequired()
493 ctl.GetFormatcodes()
494
495 *Note:* After any change in parameters, the choices for the
496 control are reevaluated to ensure that they are still legal. If you
497 have large choice lists, it is therefore more efficient to set parameters
498 before setting the choices available.
499
500 .SetFieldParameters(field_index, \*\*kwargs)
501 This function allows you to specify change individual field
502 parameters after construction. (Indices are 0-based.)
503
504 .GetFieldParameter(field_index, parametername)
505 Allows the retrieval of field parameters after construction
506
507
508 The control detects certain common constructions. In order to use the signed feature
509 (negative numbers and coloring), the mask has to be all numbers with optionally one
510 decimal point. Without a decimal (e.g. '######', the control will treat it as an integer
511 value. With a decimal (e.g. '###.##'), the control will act as a floating point control
512 (i.e. press decimal to 'tab' to the decimal position). Pressing decimal in the
513 integer control truncates the value. However, for a true numeric control,
514 masked.NumCtrl provides all this, and true numeric input/output support as well.
515
516
517 Check your controls by calling each control's .IsValid() function and the
518 .IsEmpty() function to determine which controls have been a) filled in and
519 b) filled in properly.
520
521
522 Regular expression validations can be used flexibly and creatively.
523 Take a look at the demo; the zip-code validation succeeds as long as the
524 first five numerals are entered. the last four are optional, but if
525 any are entered, there must be 4 to be valid.
526
527 masked.Ctrl Configuration
528 =========================
529 masked.Ctrl works by looking for a special *controlType*
530 parameter in the variable arguments of the control, to determine
531 what kind of instance to return.
532 controlType can be one of::
533
534 controlTypes.TEXT
535 controlTypes.COMBO
536 controlTypes.IPADDR
537 controlTypes.TIME
538 controlTypes.NUMBER
539
540 These constants are also available individually, ie, you can
541 use either of the following::
542
543 from wxPython.wx.lib.masked import MaskedCtrl, controlTypes
544 from wxPython.wx.lib.masked import MaskedCtrl, COMBO, TEXT, NUMBER, IPADDR
545
546 If not specified as a keyword argument, the default controlType is
547 controlTypes.TEXT.

555 Naming Conventions
556 ------------------
557 All methods of the Mixin that are not meant to be exposed to the external
558 interface are prefaced with '_'. Those functions that are primarily
559 intended to be internal subroutines subsequently start with a lower-case
560 letter; those that are primarily intended to be used and/or overridden
561 by derived subclasses start with a capital letter.
562
563 The following methods must be used and/or defined when deriving a control
564 from MaskedEditMixin. NOTE: if deriving from a *masked edit* control
565 (eg. class IpAddrCtrl(masked.TextCtrl) ), then this is NOT necessary,
566 as it's already been done for you in the base class.
567
568 ._SetInitialValue()
569 This function must be called after the associated base
570 control has been initialized in the subclass __init__
571 function. It sets the initial value of the control,
572 either to the value specified if non-empty, the
573 default value if specified, or the "template" for
574 the empty control as necessary. It will also set/reset
575 the font if necessary and apply formatting to the
576 control at this time.
577
578 ._GetSelection()
579 REQUIRED
580 Each class derived from MaskedEditMixin must define
581 the function for getting the start and end of the
582 current text selection. The reason for this is
583 that not all controls have the same function name for
584 doing this; eg. wx.TextCtrl uses .GetSelection(),
585 whereas we had to write a .GetMark() function for
586 wxComboBox, because .GetSelection() for the control
587 gets the currently selected list item from the combo
588 box, and the control doesn't (yet) natively provide
589 a means of determining the text selection.
590 ._SetSelection()
591 REQUIRED
592 Similarly to _GetSelection, each class derived from
593 MaskedEditMixin must define the function for setting
594 the start and end of the current text selection.
595 (eg. .SetSelection() for masked.TextCtrl, and .SetMark() for
596 masked.ComboBox.
597
598 ._GetInsertionPoint()
599 ._SetInsertionPoint()
600 REQUIRED
601 For consistency, and because the mixin shouldn't rely
602 on fixed names for any manipulations it does of any of
603 the base controls, we require each class derived from
604 MaskedEditMixin to define these functions as well.
605
606 ._GetValue()
607 ._SetValue() REQUIRED
608 Each class derived from MaskedEditMixin must define
609 the functions used to get and set the raw value of the
610 control.
611 This is necessary so that recursion doesn't take place
612 when setting the value, and so that the mixin can
613 call the appropriate function after doing all its
614 validation and manipulation without knowing what kind
615 of base control it was mixed in with. To handle undo
616 functionality, the ._SetValue() must record the current
617 selection prior to setting the value.
618
619 .Cut()
620 .Paste()
621 .Undo()
622 .SetValue() REQUIRED
623 Each class derived from MaskedEditMixin must redefine
624 these functions to call the _Cut(), _Paste(), _Undo()
625 and _SetValue() methods, respectively for the control,
626 so as to prevent programmatic corruption of the control's
627 value. This must be done in each derivation, as the
628 mixin cannot itself override a member of a sibling class.
629
630 ._Refresh() REQUIRED
631 Each class derived from MaskedEditMixin must define
632 the function used to refresh the base control.
633
634 .Refresh() REQUIRED
635 Each class derived from MaskedEditMixin must redefine
636 this function so that it checks the validity of the
637 control (via self._CheckValid) and then refreshes
638 control using the base class method.
639
640 ._IsEditable() REQUIRED
641 Each class derived from MaskedEditMixin must define
642 the function used to determine if the base control is
643 editable or not. (For masked.ComboBox, this has to
644 be done with code, rather than specifying the proper
645 function in the base control, as there isn't one...)
646 ._CalcSize() REQUIRED
647 Each class derived from MaskedEditMixin must define
648 the function used to determine how wide the control
649 should be given the mask. (The mixin function
650 ._calcSize() provides a baseline estimate.)
651
652
653 Event Handling
654 --------------
655 Event handlers are "chained", and MaskedEditMixin usually
656 swallows most of the events it sees, thereby preventing any other
657 handlers from firing in the chain. It is therefore required that
658 each class derivation using the mixin to have an option to hook up
659 the event handlers itself or forego this operation and let a
660 subclass of the masked control do so. For this reason, each
661 subclass should probably include the following code:
662
663 if setupEventHandling:
664 ## Setup event handlers
665 EVT_SET_FOCUS( self, self._OnFocus ) ## defeat automatic full selection
666 EVT_KILL_FOCUS( self, self._OnKillFocus ) ## run internal validator
667 EVT_LEFT_DCLICK(self, self._OnDoubleClick) ## select field under cursor on dclick
668 EVT_RIGHT_UP(self, self._OnContextMenu ) ## bring up an appropriate context menu
669 EVT_KEY_DOWN( self, self._OnKeyDown ) ## capture control events not normally seen, eg ctrl-tab.
670 EVT_CHAR( self, self._OnChar ) ## handle each keypress
671 EVT_TEXT( self, self.GetId(), self._OnTextChange ) ## color control appropriately & keep
672 ## track of previous value for undo
673
674 where setupEventHandling is an argument to its constructor.
675
676 These 5 handlers must be "wired up" for the masked edit
677 controls to provide default behavior. (The setupEventHandling
678 is an argument to masked.TextCtrl and masked.ComboBox, so
679 that controls derived from *them* may replace one of these
680 handlers if they so choose.)
681
682 If your derived control wants to preprocess events before
683 taking action, it should then set up the event handling itself,
684 so it can be first in the event handler chain.
685
686
687 The following routines are available to facilitate changing
688 the default behavior of masked edit controls:
689
690 ._SetKeycodeHandler(keycode, func)
691 ._SetKeyHandler(char, func)
692 Use to replace default handling for any given keycode.
693 func should take the key event as argument and return
694 False if no further action is required to handle the
695 key. Eg:
696 self._SetKeycodeHandler(WXK_UP, self.IncrementValue)
697 self._SetKeyHandler('-', self._OnChangeSign)
698
699 (Setting a func of None removes any keyhandler for the given key.)
700
701 "Navigation" keys are assumed to change the cursor position, and
702 therefore don't cause automatic motion of the cursor as insertable
703 characters do.
704
705 ._AddNavKeycode(keycode, handler=None)
706 ._AddNavKey(char, handler=None)
707 Allows controls to specify other keys (and optional handlers)
708 to be treated as navigational characters. (eg. '.' in IpAddrCtrl)
709
710 ._GetNavKeycodes() Returns the current list of navigational keycodes.
711
712 ._SetNavKeycodes(key_func_tuples)
713 Allows replacement of the current list of keycode
714 processed as navigation keys, and bind associated
715 optional keyhandlers. argument is a list of key/handler
716 tuples. Passing a value of None for the handler in a
717 given tuple indicates that default processing for the key
718 is desired.
719
720 ._FindField(pos) Returns the Field object associated with this position
721 in the control.
722
723 ._FindFieldExtent(pos, getslice=False, value=None)
724 Returns edit_start, edit_end of the field corresponding
725 to the specified position within the control, and
726 optionally also returns the current contents of that field.
727 If value is specified, it will retrieve the slice the corresponding
728 slice from that value, rather than the current value of the
729 control.
730
731 ._AdjustField(pos)
732 This is, the function that gets called for a given position
733 whenever the cursor is adjusted to leave a given field.
734 By default, it adjusts the year in date fields if mask is a date,
735 It can be overridden by a derived class to
736 adjust the value of the control at that time.
737 (eg. IpAddrCtrl reformats the address in this way.)
738
739 ._Change() Called by internal EVT_TEXT handler. Return False to force
740 skip of the normal class change event.
741 ._Keypress(key) Called by internal EVT_CHAR handler. Return False to force
742 skip of the normal class keypress event.
743 ._LostFocus() Called by internal EVT_KILL_FOCUS handler
744
745 ._OnKeyDown(event)
746 This is the default EVT_KEY_DOWN routine; it just checks for
747 "navigation keys", and if event.ControlDown(), it fires the
748 mixin's _OnChar() routine, as such events are not always seen
749 by the "cooked" EVT_CHAR routine.
750
751 ._OnChar(event) This is the main EVT_CHAR handler for the
752 MaskedEditMixin.
753
754 The following routines are used to handle standard actions
755 for control keys:
756 _OnArrow(event) used for arrow navigation events
757 _OnCtrl_A(event) 'select all'
758 _OnCtrl_C(event) 'copy' (uses base control function, as copy is non-destructive)
759 _OnCtrl_S(event) 'save' (does nothing)
760 _OnCtrl_V(event) 'paste' - calls _Paste() method, to do smart paste
761 _OnCtrl_X(event) 'cut' - calls _Cut() method, to "erase" selection
762 _OnCtrl_Z(event) 'undo' - resets value to previous value (if any)
763
764 _OnChangeField(event) primarily used for tab events, but can be
765 used for other keys (eg. '.' in IpAddrCtrl)
766
767 _OnErase(event) used for backspace and delete
768 _OnHome(event)
769 _OnEnd(event)
770
771 The following routine provides a hook back to any class derivations, so that
772 they can react to parameter changes before any value is set/reset as a result of
773 those changes. (eg. masked.ComboBox needs to detect when the choices list is
774 modified, either implicitly or explicitly, so it can reset the base control
775 to have the appropriate choice list *before* the initial value is reset to match.)
776
777 _OnCtrlParametersChanged()
778
779 Accessor Functions
780 ------------------
781 For convenience, each class derived from MaskedEditMixin should
782 define an accessors mixin, so that it exposes only those parameters
783 that make sense for the derivation. This is done with an intermediate
784 level of inheritance, ie:
785
786 class BaseMaskedTextCtrl( TextCtrl, MaskedEditMixin ):
787
788 class TextCtrl( BaseMaskedTextCtrl, MaskedEditAccessorsMixin ):
789 class ComboBox( BaseMaskedComboBox, MaskedEditAccessorsMixin ):
790 class NumCtrl( BaseMaskedTextCtrl, MaskedNumCtrlAccessorsMixin ):
791 class IpAddrCtrl( BaseMaskedTextCtrl, IpAddrCtrlAccessorsMixin ):
792 class TimeCtrl( BaseMaskedTextCtrl, TimeCtrlAccessorsMixin ):
793
794 etc.
795
796 Each accessors mixin defines Get/Set functions for the base class parameters
797 that are appropriate for that derivation.
798 This allows the base classes to be "more generic," exposing the widest
799 set of options, while not requiring derived classes to be so general.

6518 ## Current Issues:
6519 ## ===================================
6520 ##
6521 ## 1. WS: For some reason I don't understand, the control is generating two (2)
6522 ## EVT_TEXT events for every one (1) .SetValue() of the underlying control.
6523 ## I've been unsuccessful in determining why or in my efforts to make just one
6524 ## occur. So, I've added a hack to save the last seen value from the
6525 ## control in the EVT_TEXT handler, and if *different*, call event.Skip()
6526 ## to propagate it down the event chain, and let the application see it.
6527 ##
6528 ## 2. WS: MaskedComboBox is deficient in several areas, all having to do with the
6529 ## behavior of the underlying control that I can't fix. The problems are:
6530 ## a) The background coloring doesn't work in the text field of the control;
6531 ## instead, there's a only border around it that assumes the correct color.
6532 ## b) The control will not pass WXK_TAB to the event handler, no matter what
6533 ## I do, and there's no style wxCB_PROCESS_TAB like wxTE_PROCESS_TAB to
6534 ## indicate that we want these events. As a result, MaskedComboBox
6535 ## doesn't do the nice field-tabbing that MaskedTextCtrl does.
6536 ## c) Auto-complete had to be reimplemented for the control because programmatic
6537 ## setting of the value of the text field does not set up the auto complete
6538 ## the way that the control processing keystrokes does. (But I think I've
6539 ## implemented a fairly decent approximation.) Because of this the control
6540 ## also won't auto-complete on dropdown, and there's no event I can catch
6541 ## to work around this problem.
6542 ## d) There is no method provided for getting the selection; the hack I've
6543 ## implemented has its flaws, not the least of which is that due to the
6544 ## strategy that I'm using, the paste buffer is always replaced by the
6545 ## contents of the control's selection when in focus, on each keystroke;
6546 ## this makes it impossible to paste anything into a MaskedComboBox
6547 ## at the moment... :-(
6548 ## e) The other deficient behavior, likely induced by the workaround for (d),
6549 ## is that you can can't shift-left to select more than one character
6550 ## at a time.
6551 ##
6552 ##
6553 ## 3. WS: Controls on wxPanels don't seem to pass Shift-WXK_TAB to their
6554 ## EVT_KEY_DOWN or EVT_CHAR event handlers. Until this is fixed in
6555 ## wxWindows, shift-tab won't take you backwards through the fields of
6556 ## a MaskedTextCtrl like it should. Until then Shifted arrow keys will
6557 ## work like shift-tab and tab ought to.
6558 ##
6559
6560 ## To-Do's:
6561 ## =============================##
6562 ## 1. Add Popup list for auto-completable fields that simulates combobox on individual
6563 ## fields. Example: City validates against list of cities, or zip vs zip code list.
6564 ## 2. Allow optional monetary symbols (eg. $, pounds, etc.) at front of a "decimal"
6565 ## control.
6566 ## 3. Fix shift-left selection for MaskedComboBox.
6567 ## 5. Transform notion of "decimal control" to be less "entire control"-centric,
6568 ## so that monetary symbols can be included and still have the appropriate
6569 ## semantics. (Big job, as currently written, but would make control even
6570 ## more useful for business applications.)
6571
6572
6573 ## CHANGELOG:
6574 ## ====================
6575 ## Version 1.9
6576 ## 1. Now ignores kill focus events when being destroyed.
6577 ## 2. Added missing call to set insertion point on changing fields.
6578 ## 3. Modified SetKeyHandler() to accept None as means of removing one.
6579 ## 4. Fixed keyhandler processing for group and decimal character changes.
6580 ## 5. Fixed a problem that prevented input into the integer digit of a
6581 ## integerwidth=1 numctrl, if the current value was 0.
6582 ## 6. Fixed logic involving processing of "_signOk" flag, to remove default
6583 ## sign key handlers if false, so that SetAllowNegative(False) in the
6584 ## NumCtrl works properly.
6585 ## 7. Fixed selection logic for numeric controls so that if selectOnFieldEntry
6586 ## is true, and the integer portion of an integer format control is selected
6587 ## and the sign position is selected, the sign keys will always result in a
6588 ## negative value, rather than toggling the previous sign.
6589 ##
6590 ##
6591 ## Version 1.8
6592 ## 1. Fixed bug involving incorrect variable name, causing combobox autocomplete to fail.
6593 ## 2. Added proper support for unicode version of wxPython
6594 ## 3. Added * as mask char meaning "all ansi chars" (ordinals 32-255).
6595 ## 4. Converted doc strings to use reST format, for ePyDoc documentation.
6596 ## 5. Renamed helper functions, classes, etc. not intended to be visible in public
6597 ## interface to code.
6598 ##
6599 ## Version 1.7
6600 ## 1. Fixed intra-right-insert-field erase, such that it doesn't leave a hole, but instead
6601 ## shifts the text to the left accordingly.
6602 ## 2. Fixed _SetValue() to place cursor after last character inserted, rather than end of
6603 ## mask.
6604 ## 3. Fixed some incorrect undo behavior for right-insert fields, and allowed derived classes
6605 ## (eg. numctrl) to pass modified values for undo processing (to handle/ignore grouping
6606 ## chars properly.)
6607 ## 4. Fixed autoselect behavior to work similarly to (2) above, so that combobox
6608 ## selection will only select the non-empty text, as per request.
6609 ## 5. Fixed tabbing to work with 2.5.2 semantics.
6610 ## 6. Fixed size calculation to handle changing fonts
6611 ##
6612 ## Version 1.6
6613 ## 1. Reorganized masked controls into separate package, renamed things accordingly
6614 ## 2. Split actual controls out of this file into their own files.
6615 ## Version 1.5
6616 ## (Reported) bugs fixed:
6617 ## 1. Crash ensues if you attempt to change the mask of a read-only
6618 ## MaskedComboBox after initial construction.
6619 ## 2. Changed strategy of defining Get/Set property functions so that
6620 ## these are now generated dynamically at runtime, rather than as
6621 ## part of the class definition. (This makes it possible to have
6622 ## more general base classes that have many more options for configuration
6623 ## without requiring that derivations support the same options.)
6624 ## 3. Fixed IsModified for _Paste() and _OnErase().
6625 ##
6626 ## Enhancements:
6627 ## 1. Fixed "attribute function inheritance," since base control is more
6628 ## generic than subsequent derivations, not all property functions of a
6629 ## generic control should be exposed in those derivations. New strategy
6630 ## uses base control classes (eg. BaseMaskedTextCtrl) that should be
6631 ## used to derive new class types, and mixed with their own mixins to
6632 ## only expose those attributes from the generic masked controls that
6633 ## make sense for the derivation. (This makes Boa happier.)
6634 ## 2. Renamed (with b-c) MILTIME autoformats to 24HRTIME, so as to be less
6635 ## "parochial."
6636 ##
6637 ## Version 1.4
6638 ## (Reported) bugs fixed:
6639 ## 1. Right-click menu allowed "cut" operation that destroyed mask
6640 ## (was implemented by base control)
6641 ## 2. MaskedComboBox didn't allow .Append() of mixed-case values; all
6642 ## got converted to lower case.
6643 ## 3. MaskedComboBox selection didn't deal with spaces in values
6644 ## properly when autocompleting, and didn't have a concept of "next"
6645 ## match for handling choice list duplicates.
6646 ## 4. Size of MaskedComboBox was always default.
6647 ## 5. Email address regexp allowed some "non-standard" things, and wasn't
6648 ## general enough.
6649 ## 6. Couldn't easily reset MaskedComboBox contents programmatically.
6650 ## 7. Couldn't set emptyInvalid during construction.
6651 ## 8. Under some versions of wxPython, readonly comboboxes can apparently
6652 ## return a GetInsertionPoint() result (655535), causing masked control
6653 ## to fail.
6654 ## 9. Specifying an empty mask caused the controls to traceback.
6655 ## 10. Can't specify float ranges for validRange.
6656 ## 11. '.' from within a the static portion of a restricted IP address
6657 ## destroyed the mask from that point rightward; tab when cursor is
6658 ## before 1st field takes cursor past that field.
6659 ##
6660 ## Enhancements:
6661 ## 12. Added Ctrl-Z/Undo handling, (and implemented context-menu properly.)
6662 ## 13. Added auto-select option on char input for masked controls with
6663 ## choice lists.
6664 ## 14. Added '>' formatcode, allowing insert within a given or each field
6665 ## as appropriate, rather than requiring "overwrite". This makes single
6666 ## field controls that just have validation rules (eg. EMAIL) much more
6667 ## friendly. The same flag controls left shift when deleting vs just
6668 ## blanking the value, and for right-insert fields, allows right-insert
6669 ## at any non-blank (non-sign) position in the field.
6670 ## 15. Added option to use to indicate negative values for numeric controls.
6671 ## 16. Improved OnFocus handling of numeric controls.
6672 ## 17. Enhanced Home/End processing to allow operation on a field level,
6673 ## using ctrl key.
6674 ## 18. Added individual Get/Set functions for control parameters, for
6675 ## simplified integration with Boa Constructor.
6676 ## 19. Standardized "Colour" parameter names to match wxPython, with
6677 ## non-british spellings still supported for backward-compatibility.
6678 ## 20. Added '&' mask specification character for punctuation only (no letters
6679 ## or digits).
6680 ## 21. Added (in a separate file) wx.MaskedCtrl() factory function to provide
6681 ## unified interface to the masked edit subclasses.
6682 ##
6683 ##
6684 ## Version 1.3
6685 ## 1. Made it possible to configure grouping, decimal and shift-decimal characters,
6686 ## to make controls more usable internationally.
6687 ## 2. Added code to smart "adjust" value strings presented to .SetValue()
6688 ## for right-aligned numeric format controls if they are shorter than
6689 ## than the control width, prepending the missing portion, prepending control
6690 ## template left substring for the missing characters, so that setting
6691 ## numeric values is easier.
6692 ## 3. Renamed SetMaskParameters SetCtrlParameters() (with old name preserved
6693 ## for b-c), as this makes more sense.
6694 ##
6695 ## Version 1.2
6696 ## 1. Fixed .SetValue() to replace the current value, rather than the current
6697 ## selection. Also changed it to generate ValueError if presented with
6698 ## either a value which doesn't follow the format or won't fit. Also made
6699 ## set value adjust numeric and date controls as if user entered the value.
6700 ## Expanded doc explaining how SetValue() works.
6701 ## 2. Fixed EUDATE* autoformats, fixed IsDateType mask list, and added ability to
6702 ## use 3-char months for dates, and EUDATETIME, and EUDATEMILTIME autoformats.
6703 ## 3. Made all date autoformats automatically pick implied "datestyle".
6704 ## 4. Added IsModified override, since base wx.TextCtrl never reports modified if
6705 ## .SetValue used to change the value, which is what the masked edit controls
6706 ## use internally.
6707 ## 5. Fixed bug in date position adjustment on 2 to 4 digit date conversion when
6708 ## using tab to "leave field" and auto-adjust.
6709 ## 6. Fixed bug in _isCharAllowed() for negative number insertion on pastes,
6710 ## and bug in ._Paste() that didn't account for signs in signed masks either.
6711 ## 7. Fixed issues with _adjustPos for right-insert fields causing improper
6712 ## selection/replacement of values
6713 ## 8. Fixed _OnHome handler to properly handle extending current selection to
6714 ## beginning of control.
6715 ## 9. Exposed all (valid) autoformats to demo, binding descriptions to
6716 ## autoformats.
6717 ## 10. Fixed a couple of bugs in email regexp.
6718 ## 11. Made maskchardict an instance var, to make mask chars to be more
6719 ## amenable to international use.
6720 ## 12. Clarified meaning of '-' formatcode in doc.
6721 ## 13. Fixed a couple of coding bugs being flagged by Python2.1.
6722 ## 14. Fixed several issues with sign positioning, erasure and validity
6723 ## checking for "numeric" masked controls.
6724 ## 15. Added validation to IpAddrCtrl.SetValue().
6725 ##
6726 ## Version 1.1
6727 ## 1. Changed calling interface to use boolean "useFixedWidthFont" (True by default)
6728 ## vs. literal font facename, and use wxTELETYPE as the font family
6729 ## if so specified.
6730 ## 2. Switched to use of dbg module vs. locally defined version.
6731 ## 3. Revamped entire control structure to use Field classes to hold constraint
6732 ## and formatting data, to make code more hierarchical, allow for more
6733 ## sophisticated masked edit construction.
6734 ## 4. Better strategy for managing options, and better validation on keywords.
6735 ## 5. Added 'V' format code, which requires that in order for a character
6736 ## to be accepted, it must result in a string that passes the validRegex.
6737 ## 6. Added 'S' format code which means "select entire field when navigating
6738 ## to new field."
6739 ## 7. Added 'r' format code to allow "right-insert" fields. (implies 'R'--right-alignment)
6740 ## 8. Added '<' format code to allow fields to require explicit cursor movement
6741 ## to leave field.
6742 ## 9. Added validFunc option to other validation mechanisms, that allows derived
6743 ## classes to add dynamic validation constraints to the control.
6744 ## 10. Fixed bug in validatePaste code causing possible IndexErrors, and also
6745 ## fixed failure to obey case conversion codes when pasting.
6746 ## 11. Implemented '0' (zero-pad) formatting code, as it wasn't being done anywhere...
6747 ## 12. Removed condition from OnDecimalPoint, so that it always truncates right on '.'
6748 ## 13. Enhanced IpAddrCtrl to use right-insert fields, selection on field traversal,
6749 ## individual field validation to prevent field values > 255, and require explicit
6750 ## tab/. to change fields.
6751 ## 14. Added handler for left double-click to select field under cursor.
6752 ## 15. Fixed handling for "Read-only" styles.
6753 ## 16. Separated signedForegroundColor from 'R' style, and added foregroundColor
6754 ## attribute, for more consistent and controllable coloring.
6755 ## 17. Added retainFieldValidation parameter, allowing top-level constraints
6756 ## such as "validRequired" to be set independently of field-level equivalent.
6757 ## (needed in TimeCtrl for bounds constraints.)
6758 ## 18. Refactored code a bit, cleaned up and commented code more heavily, fixed
6759 ## some of the logic for setting/resetting parameters, eg. fillChar, defaultValue,
6760 ## etc.
6761 ## 19. Fixed maskchar setting for upper/lowercase, to work in all locales.
6762 ##
6763 ##
6764 ## Version 1.0
6765 ## 1. Decimal point behavior restored for decimal and integer type controls:
6766 ## decimal point now trucates the portion > 0.
6767 ## 2. Return key now works like the tab character and moves to the next field,
6768 ## provided no default button is set for the form panel on which the control
6769 ## resides.
6770 ## 3. Support added in _FindField() for subclasses controls (like timecontrol)
6771 ## to determine where the current insertion point is within the mask (i.e.
6772 ## which sub-'field'). See method documentation for more info and examples.
6773 ## 4. Added Field class and support for all constraints to be field-specific
6774 ## in addition to being globally settable for the control.
6775 ## Choices for each field are validated for length and pastability into
6776 ## the field in question, raising ValueError if not appropriate for the control.
6777 ## Also added selective additional validation based on individual field constraints.
6778 ## By default, SHIFT-WXK_DOWN, SHIFT-WXK_UP, WXK_PRIOR and WXK_NEXT all
6779 ## auto-complete fields with choice lists, supplying the 1st entry in
6780 ## the choice list if the field is empty, and cycling through the list in
6781 ## the appropriate direction if already a match. WXK_DOWN will also auto-
6782 ## complete if the field is partially completed and a match can be made.
6783 ## SHIFT-WXK_UP/DOWN will also take you to the next field after any
6784 ## auto-completion performed.
6785 ## 5. Added autoCompleteKeycodes=[] parameters for allowing further
6786 ## customization of the control. Any keycode supplied as a member
6787 ## of the _autoCompleteKeycodes list will be treated like WXK_NEXT. If
6788 ## requireFieldChoice is set, then a valid value from each non-empty
6789 ## choice list will be required for the value of the control to validate.
6790 ## 6. Fixed "auto-sizing" to be relative to the font actually used, rather
6791 ## than making assumptions about character width.
6792 ## 7. Fixed GetMaskParameter(), which was non-functional in previous version.
6793 ## 8. Fixed exceptions raised to provide info on which control had the error.
6794 ## 9. Fixed bug in choice management of MaskedComboBox.
6795 ## 10. Fixed bug in IpAddrCtrl causing traceback if field value was of
6796 ## the form '# #'. Modified control code for IpAddrCtrl so that '.'
6797 ## in the middle of a field clips the rest of that field, similar to
6798 ## decimal and integer controls.
6799 ##
6800 ##
6801 ## Version 0.0.7
6802 ## 1. "-" is a toggle for sign; "+" now changes - signed numerics to positive.
6803 ## 2. ',' in formatcodes now causes numeric values to be comma-delimited (e.g.333,333).
6804 ## 3. New support for selecting text within the control.(thanks Will Sadkin!)
6805 ## Shift-End and Shift-Home now select text as you would expect
6806 ## Control-Shift-End selects to the end of the mask string, even if value not entered.
6807 ## Control-A selects all *entered* text, Shift-Control-A selects everything in the control.
6808 ## 4. event.Skip() added to onKillFocus to correct remnants when running in Linux (contributed-
6809 ## for some reason I couldn't find the original email but thanks!!!)
6810 ## 5. All major key-handling code moved to their own methods for easier subclassing: OnHome,
6811 ## OnErase, OnEnd, OnCtrl_X, OnCtrl_A, etc.
6812 ## 6. Email and autoformat validations corrected using regex provided by Will Sadkin (thanks!).
6813 ## (The rest of the changes in this version were done by Will Sadkin with permission from Jeff...)
6814 ## 7. New mechanism for replacing default behavior for any given key, using
6815 ## ._SetKeycodeHandler(keycode, func) and ._SetKeyHandler(char, func) now available
6816 ## for easier subclassing of the control.
6817 ## 8. Reworked the delete logic, cut, paste and select/replace logic, as well as some bugs
6818 ## with insertion point/selection modification. Changed Ctrl-X to use standard "cut"
6819 ## semantics, erasing the selection, rather than erasing the entire control.
6820 ## 9. Added option for an "default value" (ie. the template) for use when a single fillChar
6821 ## is not desired in every position. Added IsDefault() function to mean "does the value
6822 ## equal the template?" and modified .IsEmpty() to mean "do all of the editable
6823 ## positions in the template == the fillChar?"
6824 ## 10. Extracted mask logic into mixin, so we can have both MaskedTextCtrl and MaskedComboBox,
6825 ## now included.
6826 ## 11. MaskedComboBox now adds the capability to validate from list of valid values.
6827 ## Example: City validates against list of cities, or zip vs zip code list.
6828 ## 12. Fixed oversight in EVT_TEXT handler that prevented the events from being
6829 ## passed to the next handler in the event chain, causing updates to the
6830 ## control to be invisible to the parent code.
6831 ## 13. Added IPADDR autoformat code, and subclass IpAddrCtrl for controlling tabbing within
6832 ## the control, that auto-reformats as you move between cells.
6833 ## 14. Mask characters [A,a,X,#] can now appear in the format string as literals, by using '\'.
6834 ## 15. It is now possible to specify repeating masks, e.g. #{3}-#{3}-#{14}
6835 ## 16. Fixed major bugs in date validation, due to the fact that
6836 ## wxDateTime.ParseDate is too liberal, and will accept any form that
6837 ## makes any kind of sense, regardless of the datestyle you specified
6838 ## for the control. Unfortunately, the strategy used to fix it only
6839 ## works for versions of wxPython post 2.3.3.1, as a C++ assert box
6840 ## seems to show up on an invalid date otherwise, instead of a catchable
6841 ## exception.
6842 ## 17. Enhanced date adjustment to automatically adjust heuristic based on
6843 ## current year, making last century/this century determination on
6844 ## 2-digit year based on distance between today's year and value;
6845 ## if > 50 year separation, assume last century (and don't assume last
6846 ## century is 20th.)
6847 ## 18. Added autoformats and support for including HHMMSS as well as HHMM for
6848 ## date times, and added similar time, and militaray time autoformats.
6849 ## 19. Enhanced tabbing logic so that tab takes you to the next field if the
6850 ## control is a multi-field control.
6851 ## 20. Added stub method called whenever the control "changes fields", that
6852 ## can be overridden by subclasses (eg. IpAddrCtrl.)
6853 ## 21. Changed a lot of code to be more functionally-oriented so side-effects
6854 ## aren't as problematic when maintaining code and/or adding features.
6855 ## Eg: IsValid() now does not have side-effects; it merely reflects the
6856 ## validity of the value of the control; to determine validity AND recolor
6857 ## the control, _CheckValid() should be used with a value argument of None.
6858 ## Similarly, made most reformatting function take an optional candidate value
6859 ## rather than just using the current value of the control, and only
6860 ## have them change the value of the control if a candidate is not specified.
6861 ## In this way, you can do validation *before* changing the control.
6862 ## 22. Changed validRequired to mean "disallow chars that result in invalid
6863 ## value." (Old meaning now represented by emptyInvalid.) (This was
6864 ## possible once I'd made the changes in (19) above.)
6865 ## 23. Added .SetMaskParameters and .GetMaskParameter methods, so they
6866 ## can be set/modified/retrieved after construction. Removed individual
6867 ## parameter setting functions, in favor of this mechanism, so that
6868 ## all adjustment of the control based on changing parameter values can
6869 ## be handled in one place with unified mechanism.
6870 ## 24. Did a *lot* of testing and fixing re: numeric values. Added ability
6871 ## to type "grouping char" (ie. ',') and validate as appropriate.
6872 ## 25. Fixed ZIPPLUS4 to allow either 5 or 4, but if > 5 must be 9.
6873 ## 26. Fixed assumption about "decimal or integer" masks so that they're only
6874 ## made iff there's no validRegex associated with the field. (This
6875 ## is so things like zipcodes which look like integers can have more
6876 ## restrictive validation (ie. must be 5 digits.)
6877 ## 27. Added a ton more doc strings to explain use and derivation requirements
6878 ## and did regularization of the naming conventions.
6879 ## 28. Fixed a range bug in _adjustKey preventing z from being handled properly.
6880 ## 29. Changed behavior of '.' (and shift-.) in numeric controls to move to
6881 ## reformat the value and move the next field as appropriate. (shift-'.',
6882 ## ie. '>' moves to the previous field.
6883
6884 ## Version 0.0.6
6885 ## 1. Fixed regex bug that caused autoformat AGE to invalidate any age ending
6886 ## in '0'.
6887 ## 2. New format character 'D' to trigger date type. If the user enters 2 digits in the
6888 ## year position, the control will expand the value to four digits, using numerals below
6889 ## 50 as 21st century (20+nn) and less than 50 as 20th century (19+nn).
6890 ## Also, new optional parameter datestyle = set to one of {MDY|DMY|YDM}
6891 ## 3. revalid parameter renamed validRegex to conform to standard for all validation
6892 ## parameters (see 2 new ones below).
6893 ## 4. New optional init parameter = validRange. Used only for int/dec (numeric) types.
6894 ## Allows the developer to specify a valid low/high range of values.
6895 ## 5. New optional init parameter = validList. Used for character types. Allows developer
6896 ## to send a list of values to the control to be used for specific validation.
6897 ## See the Last Name Only example - it is list restricted to Smith/Jones/Williams.
6898 ## 6. Date type fields now use wxDateTime's parser to validate the date and time.
6899 ## This works MUCH better than my kludgy regex!! Thanks to Robin Dunn for pointing
6900 ## me toward this solution!
6901 ## 7. Date fields now automatically expand 2-digit years when it can. For example,
6902 ## if the user types "03/10/67", then "67" will auto-expand to "1967". If a two-year
6903 ## date is entered it will be expanded in any case when the user tabs out of the
6904 ## field.
6905 ## 8. New class functions: SetValidBackgroundColor, SetInvalidBackgroundColor, SetEmptyBackgroundColor,
6906 ## SetSignedForeColor allow accessto override default class coloring behavior.
6907 ## 9. Documentation updated and improved.
6908 ## 10. Demo - page 2 is now a wxFrame class instead of a wxPyApp class. Works better.
6909 ## Two new options (checkboxes) - test highlight empty and disallow empty.
6910 ## 11. Home and End now work more intuitively, moving to the first and last user-entry
6911 ## value, respectively.
6912 ## 12. New class function: SetRequired(bool). Sets the control's entry required flag
6913 ## (i.e. disallow empty values if True).
6914 ##
6915 ## Version 0.0.5
6916 ## 1. get_plainValue method renamed to GetPlainValue following the wxWindows
6917 ## StudlyCaps(tm) standard (thanks Paul Moore). ;)
6918 ## 2. New format code 'F' causes the control to auto-fit (auto-size) itself
6919 ## based on the length of the mask template.
6920 ## 3. Class now supports "autoformat" codes. These can be passed to the class
6921 ## on instantiation using the parameter autoformat="code". If the code is in
6922 ## the dictionary, it will self set the mask, formatting, and validation string.
6923 ## I have included a number of samples, but I am hoping that someone out there
6924 ## can help me to define a whole bunch more.
6925 ## 4. I have added a second page to the demo (as well as a second demo class, test2)
6926 ## to showcase how autoformats work. The way they self-format and self-size is,
6927 ## I must say, pretty cool.
6928 ## 5. Comments added and some internal cosmetic revisions re: matching the code
6929 ## standards for class submission.
6930 ## 6. Regex validation is now done in real time - field turns yellow immediately
6931 ## and stays yellow until the entered value is valid
6932 ## 7. Cursor now skips over template characters in a more intuitive way (before the
6933 ## next keypress).
6934 ## 8. Change, Keypress and LostFocus methods added for convenience of subclasses.
6935 ## Developer may use these methods which will be called after EVT_TEXT, EVT_CHAR,
6936 ## and EVT_KILL_FOCUS, respectively.
6937 ## 9. Decimal and numeric handlers have been rewritten and now work more intuitively.
6938 ##
6939 ## Version 0.0.4
6940 ## 1. New .IsEmpty() method returns True if the control's value is equal to the
6941 ## blank template string
6942 ## 2. Control now supports a new init parameter: revalid. Pass a regular expression
6943 ## that the value will have to match when the control loses focus. If invalid,
6944 ## the control's BackgroundColor will turn yellow, and an internal flag is set (see next).
6945 ## 3. Demo now shows revalid functionality. Try entering a partial value, such as a
6946 ## partial social security number.
6947 ## 4. New .IsValid() value returns True if the control is empty, or if the value matches
6948 ## the revalid expression. If not, .IsValid() returns False.
6949 ## 5. Decimal values now collapse to decimal with '.00' on losefocus if the user never
6950 ## presses the decimal point.
6951 ## 6. Cursor now goes to the beginning of the field if the user clicks in an
6952 ## "empty" field intead of leaving the insertion point in the middle of the
6953 ## field.
6954 ## 7. New "N" mask type includes upper and lower chars plus digits. a-zA-Z0-9.
6955 ## 8. New formatcodes init parameter replaces other init params and adds functions.
6956 ## String passed to control on init controls:
6957 ## _ Allow spaces
6958 ## ! Force upper
6959 ## ^ Force lower
6960 ## R Show negative #s in red
6961 ## , Group digits
6962 ## - Signed numerals
6963 ## 0 Numeric fields get leading zeros
6964 ## 9. Ctrl-X in any field clears the current value.
6965 ## 10. Code refactored and made more modular (esp in OnChar method). Should be more
6966 ## easy to read and understand.
6967 ## 11. Demo enhanced.
6968 ## 12. Now has _doc_.
6969 ##
6970 ## Version 0.0.3
6971 ## 1. GetPlainValue() now returns the value without the template characters;
6972 ## so, for example, a social security number (123-33-1212) would return as
6973 ## 123331212; also removes white spaces from numeric/decimal values, so
6974 ## "- 955.32" is returned "-955.32". Press ctrl-S to see the plain value.
6975 ## 2. Press '.' in an integer style masked control and truncate any trailing digits.
6976 ## 3. Code moderately refactored. Internal names improved for clarity. Additional
6977 ## internal documentation.
6978 ## 4. Home and End keys now supported to move cursor to beginning or end of field.
6979 ## 5. Un-signed integers and decimals now supported.
6980 ## 6. Cosmetic improvements to the demo.
6981 ## 7. Class renamed to MaskedTextCtrl.
6982 ## 8. Can now specify include characters that will override the basic
6983 ## controls: for example, includeChars = "@." for email addresses
6984 ## 9. Added mask character 'C' -> allow any upper or lowercase character
6985 ## 10. .SetSignColor(str:color) sets the foreground color for negative values
6986 ## in signed controls (defaults to red)
6987 ## 11. Overview documentation written.
6988 ##
6989 ## Version 0.0.2
6990 ## 1. Tab now works properly when pressed in last position
6991 ## 2. Decimal types now work (e.g. #####.##)
6992 ## 3. Signed decimal or numeric values supported (i.e. negative numbers)
6993 ## 4. Negative decimal or numeric values now can show in red.
6994 ## 5. Can now specify an "exclude list" with the excludeChars parameter.
6995 ## See date/time formatted example - you can only enter A or P in the
6996 ## character mask space (i.e. AM/PM).
6997 ## 6. Backspace now works properly, including clearing data from a selected
6998 ## region but leaving template characters intact. Also delete key.
6999 ## 7. Left/right arrows now work properly.
7000 ## 8. Removed EventManager call from test so demo should work with wxPython 2.3.3
7001 ##
