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

500 DEVELOPER COMMENTS:
501
502 Naming Conventions
503 ------------------
504 All methods of the Mixin that are not meant to be exposed to the external
505 interface are prefaced with '_'. Those functions that are primarily
506 intended to be internal subroutines subsequently start with a lower-case
507 letter; those that are primarily intended to be used and/or overridden
508 by derived subclasses start with a capital letter.
509
510 The following methods must be used and/or defined when deriving a control
511 from MaskedEditMixin. NOTE: if deriving from a *masked edit* control
512 (eg. class IpAddrCtrl(masked.TextCtrl) ), then this is NOT necessary,
513 as it's already been done for you in the base class.
514
515 ._SetInitialValue()
516 This function must be called after the associated base
517 control has been initialized in the subclass __init__
518 function. It sets the initial value of the control,
519 either to the value specified if non-empty, the
520 default value if specified, or the "template" for
521 the empty control as necessary. It will also set/reset
522 the font if necessary and apply formatting to the
523 control at this time.
524
525 ._GetSelection()
526 REQUIRED
527 Each class derived from MaskedEditMixin must define
528 the function for getting the start and end of the
529 current text selection. The reason for this is
530 that not all controls have the same function name for
531 doing this; eg. wx.TextCtrl uses .GetSelection(),
532 whereas we had to write a .GetMark() function for
533 wxComboBox, because .GetSelection() for the control
534 gets the currently selected list item from the combo
535 box, and the control doesn't (yet) natively provide
536 a means of determining the text selection.
537 ._SetSelection()
538 REQUIRED
539 Similarly to _GetSelection, each class derived from
540 MaskedEditMixin must define the function for setting
541 the start and end of the current text selection.
542 (eg. .SetSelection() for masked.TextCtrl, and .SetMark() for
543 masked.ComboBox.
544
545 ._GetInsertionPoint()
546 ._SetInsertionPoint()
547 REQUIRED
548 For consistency, and because the mixin shouldn't rely
549 on fixed names for any manipulations it does of any of
550 the base controls, we require each class derived from
551 MaskedEditMixin to define these functions as well.
552
553 ._GetValue()
554 ._SetValue() REQUIRED
555 Each class derived from MaskedEditMixin must define
556 the functions used to get and set the raw value of the
557 control.
558 This is necessary so that recursion doesn't take place
559 when setting the value, and so that the mixin can
560 call the appropriate function after doing all its
561 validation and manipulation without knowing what kind
562 of base control it was mixed in with. To handle undo
563 functionality, the ._SetValue() must record the current
564 selection prior to setting the value.
565
566 .Cut()
567 .Paste()
568 .Undo()
569 .SetValue() REQUIRED
570 Each class derived from MaskedEditMixin must redefine
571 these functions to call the _Cut(), _Paste(), _Undo()
572 and _SetValue() methods, respectively for the control,
573 so as to prevent programmatic corruption of the control's
574 value. This must be done in each derivation, as the
575 mixin cannot itself override a member of a sibling class.
576
577 ._Refresh() REQUIRED
578 Each class derived from MaskedEditMixin must define
579 the function used to refresh the base control.
580
581 .Refresh() REQUIRED
582 Each class derived from MaskedEditMixin must redefine
583 this function so that it checks the validity of the
584 control (via self._CheckValid) and then refreshes
585 control using the base class method.
586
587 ._IsEditable() REQUIRED
588 Each class derived from MaskedEditMixin must define
589 the function used to determine if the base control is
590 editable or not. (For masked.ComboBox, this has to
591 be done with code, rather than specifying the proper
592 function in the base control, as there isn't one...)
593 ._CalcSize() REQUIRED
594 Each class derived from MaskedEditMixin must define
595 the function used to determine how wide the control
596 should be given the mask. (The mixin function
597 ._calcSize() provides a baseline estimate.)
598
599
600 Event Handling
601 --------------
602 Event handlers are "chained", and MaskedEditMixin usually
603 swallows most of the events it sees, thereby preventing any other
604 handlers from firing in the chain. It is therefore required that
605 each class derivation using the mixin to have an option to hook up
606 the event handlers itself or forego this operation and let a
607 subclass of the masked control do so. For this reason, each
608 subclass should probably include the following code:
609
610 if setupEventHandling:
611 ## Setup event handlers
612 EVT_SET_FOCUS( self, self._OnFocus ) ## defeat automatic full selection
613 EVT_KILL_FOCUS( self, self._OnKillFocus ) ## run internal validator
614 EVT_LEFT_DCLICK(self, self._OnDoubleClick) ## select field under cursor on dclick
615 EVT_RIGHT_UP(self, self._OnContextMenu ) ## bring up an appropriate context menu
616 EVT_KEY_DOWN( self, self._OnKeyDown ) ## capture control events not normally seen, eg ctrl-tab.
617 EVT_CHAR( self, self._OnChar ) ## handle each keypress
618 EVT_TEXT( self, self.GetId(), self._OnTextChange ) ## color control appropriately & keep
619 ## track of previous value for undo
620
621 where setupEventHandling is an argument to its constructor.
622
623 These 5 handlers must be "wired up" for the masked edit
624 controls to provide default behavior. (The setupEventHandling
625 is an argument to masked.TextCtrl and masked.ComboBox, so
626 that controls derived from *them* may replace one of these
627 handlers if they so choose.)
628
629 If your derived control wants to preprocess events before
630 taking action, it should then set up the event handling itself,
631 so it can be first in the event handler chain.
632
633
634 The following routines are available to facilitate changing
635 the default behavior of masked edit controls:
636
637 ._SetKeycodeHandler(keycode, func)
638 ._SetKeyHandler(char, func)
639 Use to replace default handling for any given keycode.
640 func should take the key event as argument and return
641 False if no further action is required to handle the
642 key. Eg:
643 self._SetKeycodeHandler(WXK_UP, self.IncrementValue)
644 self._SetKeyHandler('-', self._OnChangeSign)
645
646 "Navigation" keys are assumed to change the cursor position, and
647 therefore don't cause automatic motion of the cursor as insertable
648 characters do.
649
650 ._AddNavKeycode(keycode, handler=None)
651 ._AddNavKey(char, handler=None)
652 Allows controls to specify other keys (and optional handlers)
653 to be treated as navigational characters. (eg. '.' in IpAddrCtrl)
654
655 ._GetNavKeycodes() Returns the current list of navigational keycodes.
656
657 ._SetNavKeycodes(key_func_tuples)
658 Allows replacement of the current list of keycode
659 processed as navigation keys, and bind associated
660 optional keyhandlers. argument is a list of key/handler
661 tuples. Passing a value of None for the handler in a
662 given tuple indicates that default processing for the key
663 is desired.
664
665 ._FindField(pos) Returns the Field object associated with this position
666 in the control.
667
668 ._FindFieldExtent(pos, getslice=False, value=None)
669 Returns edit_start, edit_end of the field corresponding
670 to the specified position within the control, and
671 optionally also returns the current contents of that field.
672 If value is specified, it will retrieve the slice the corresponding
673 slice from that value, rather than the current value of the
674 control.
675
676 ._AdjustField(pos)
677 This is, the function that gets called for a given position
678 whenever the cursor is adjusted to leave a given field.
679 By default, it adjusts the year in date fields if mask is a date,
680 It can be overridden by a derived class to
681 adjust the value of the control at that time.
682 (eg. IpAddrCtrl reformats the address in this way.)
683
684 ._Change() Called by internal EVT_TEXT handler. Return False to force
685 skip of the normal class change event.
686 ._Keypress(key) Called by internal EVT_CHAR handler. Return False to force
687 skip of the normal class keypress event.
688 ._LostFocus() Called by internal EVT_KILL_FOCUS handler
689
690 ._OnKeyDown(event)
691 This is the default EVT_KEY_DOWN routine; it just checks for
692 "navigation keys", and if event.ControlDown(), it fires the
693 mixin's _OnChar() routine, as such events are not always seen
694 by the "cooked" EVT_CHAR routine.
695
696 ._OnChar(event) This is the main EVT_CHAR handler for the
697 MaskedEditMixin.
698
699 The following routines are used to handle standard actions
700 for control keys:
701 _OnArrow(event) used for arrow navigation events
702 _OnCtrl_A(event) 'select all'
703 _OnCtrl_C(event) 'copy' (uses base control function, as copy is non-destructive)
704 _OnCtrl_S(event) 'save' (does nothing)
705 _OnCtrl_V(event) 'paste' - calls _Paste() method, to do smart paste
706 _OnCtrl_X(event) 'cut' - calls _Cut() method, to "erase" selection
707 _OnCtrl_Z(event) 'undo' - resets value to previous value (if any)
708
709 _OnChangeField(event) primarily used for tab events, but can be
710 used for other keys (eg. '.' in IpAddrCtrl)
711
712 _OnErase(event) used for backspace and delete
713 _OnHome(event)
714 _OnEnd(event)
715
716 The following routine provides a hook back to any class derivations, so that
717 they can react to parameter changes before any value is set/reset as a result of
718 those changes. (eg. masked.ComboBox needs to detect when the choices list is
719 modified, either implicitly or explicitly, so it can reset the base control
720 to have the appropriate choice list *before* the initial value is reset to match.)
721
722 _OnCtrlParametersChanged()
723
724 Accessor Functions
725 ------------------
726 For convenience, each class derived from MaskedEditMixin should
727 define an accessors mixin, so that it exposes only those parameters
728 that make sense for the derivation. This is done with an intermediate
729 level of inheritance, ie:
730
731 class BaseMaskedTextCtrl( TextCtrl, MaskedEditMixin ):
732
733 class TextCtrl( BaseMaskedTextCtrl, MaskedEditAccessorsMixin ):
734 class ComboBox( BaseMaskedComboBox, MaskedEditAccessorsMixin ):
735 class NumCtrl( BaseMaskedTextCtrl, MaskedNumCtrlAccessorsMixin ):
736 class IpAddrCtrl( BaseMaskedTextCtrl, IpAddrCtrlAccessorsMixin ):
737 class TimeCtrl( BaseMaskedTextCtrl, TimeCtrlAccessorsMixin ):
738
739 etc.
740
741 Each accessors mixin defines Get/Set functions for the base class parameters
742 that are appropriate for that derivation.
743 This allows the base classes to be "more generic," exposing the widest
744 set of options, while not requiring derived classes to be so general.

6230 ##
6231 ## Current Issues:
6232 ## ===================================
6233 ##
6234 ## 1. WS: For some reason I don't understand, the control is generating two (2)
6235 ## EVT_TEXT events for every one (1) .SetValue() of the underlying control.
6236 ## I've been unsuccessful in determining why or in my efforts to make just one
6237 ## occur. So, I've added a hack to save the last seen value from the
6238 ## control in the EVT_TEXT handler, and if *different*, call event.Skip()
6239 ## to propagate it down the event chain, and let the application see it.
6240 ##
6241 ## 2. WS: MaskedComboBox is deficient in several areas, all having to do with the
6242 ## behavior of the underlying control that I can't fix. The problems are:
6243 ## a) The background coloring doesn't work in the text field of the control;
6244 ## instead, there's a only border around it that assumes the correct color.
6245 ## b) The control will not pass WXK_TAB to the event handler, no matter what
6246 ## I do, and there's no style wxCB_PROCESS_TAB like wxTE_PROCESS_TAB to
6247 ## indicate that we want these events. As a result, MaskedComboBox
6248 ## doesn't do the nice field-tabbing that MaskedTextCtrl does.
6249 ## c) Auto-complete had to be reimplemented for the control because programmatic
6250 ## setting of the value of the text field does not set up the auto complete
6251 ## the way that the control processing keystrokes does. (But I think I've
6252 ## implemented a fairly decent approximation.) Because of this the control
6253 ## also won't auto-complete on dropdown, and there's no event I can catch
6254 ## to work around this problem.
6255 ## d) There is no method provided for getting the selection; the hack I've
6256 ## implemented has its flaws, not the least of which is that due to the
6257 ## strategy that I'm using, the paste buffer is always replaced by the
6258 ## contents of the control's selection when in focus, on each keystroke;
6259 ## this makes it impossible to paste anything into a MaskedComboBox
6260 ## at the moment... :-(
6261 ## e) The other deficient behavior, likely induced by the workaround for (d),
6262 ## is that you can can't shift-left to select more than one character
6263 ## at a time.
6264 ##
6265 ##
6266 ## 3. WS: Controls on wxPanels don't seem to pass Shift-WXK_TAB to their
6267 ## EVT_KEY_DOWN or EVT_CHAR event handlers. Until this is fixed in
6268 ## wxWindows, shift-tab won't take you backwards through the fields of
6269 ## a MaskedTextCtrl like it should. Until then Shifted arrow keys will
6270 ## work like shift-tab and tab ought to.
6271 ##
6272
6273 ## To-Do's:
6274 ## =============================##
6275 ## 1. Add Popup list for auto-completable fields that simulates combobox on individual
6276 ## fields. Example: City validates against list of cities, or zip vs zip code list.
6277 ## 2. Allow optional monetary symbols (eg. $, pounds, etc.) at front of a "decimal"
6278 ## control.
6279 ## 3. Fix shift-left selection for MaskedComboBox.
6280 ## 5. Transform notion of "decimal control" to be less "entire control"-centric,
6281 ## so that monetary symbols can be included and still have the appropriate
6282 ## semantics. (Big job, as currently written, but would make control even
6283 ## more useful for business applications.)
6284
6285
6286 ## CHANGELOG:
6287 ## ====================
6288 ## Version 1.6
6289 ## 1. Reorganized masked controls into separate package, renamed things accordingly
6290 ## 2. Split actual controls out of this file into their own files.
6291 ## Version 1.5
6292 ## (Reported) bugs fixed:
6293 ## 1. Crash ensues if you attempt to change the mask of a read-only
6294 ## MaskedComboBox after initial construction.
6295 ## 2. Changed strategy of defining Get/Set property functions so that
6296 ## these are now generated dynamically at runtime, rather than as
6297 ## part of the class definition. (This makes it possible to have
6298 ## more general base classes that have many more options for configuration
6299 ## without requiring that derivations support the same options.)
6300 ## 3. Fixed IsModified for _Paste() and _OnErase().
6301 ##
6302 ## Enhancements:
6303 ## 1. Fixed "attribute function inheritance," since base control is more
6304 ## generic than subsequent derivations, not all property functions of a
6305 ## generic control should be exposed in those derivations. New strategy
6306 ## uses base control classes (eg. BaseMaskedTextCtrl) that should be
6307 ## used to derive new class types, and mixed with their own mixins to
6308 ## only expose those attributes from the generic masked controls that
6309 ## make sense for the derivation. (This makes Boa happier.)
6310 ## 2. Renamed (with b-c) MILTIME autoformats to 24HRTIME, so as to be less
6311 ## "parochial."
6312 ##
6313 ## Version 1.4
6314 ## (Reported) bugs fixed:
6315 ## 1. Right-click menu allowed "cut" operation that destroyed mask
6316 ## (was implemented by base control)
6317 ## 2. MaskedComboBox didn't allow .Append() of mixed-case values; all
6318 ## got converted to lower case.
6319 ## 3. MaskedComboBox selection didn't deal with spaces in values
6320 ## properly when autocompleting, and didn't have a concept of "next"
6321 ## match for handling choice list duplicates.
6322 ## 4. Size of MaskedComboBox was always default.
6323 ## 5. Email address regexp allowed some "non-standard" things, and wasn't
6324 ## general enough.
6325 ## 6. Couldn't easily reset MaskedComboBox contents programmatically.
6326 ## 7. Couldn't set emptyInvalid during construction.
6327 ## 8. Under some versions of wxPython, readonly comboboxes can apparently
6328 ## return a GetInsertionPoint() result (655535), causing masked control
6329 ## to fail.
6330 ## 9. Specifying an empty mask caused the controls to traceback.
6331 ## 10. Can't specify float ranges for validRange.
6332 ## 11. '.' from within a the static portion of a restricted IP address
6333 ## destroyed the mask from that point rightward; tab when cursor is
6334 ## before 1st field takes cursor past that field.
6335 ##
6336 ## Enhancements:
6337 ## 12. Added Ctrl-Z/Undo handling, (and implemented context-menu properly.)
6338 ## 13. Added auto-select option on char input for masked controls with
6339 ## choice lists.
6340 ## 14. Added '>' formatcode, allowing insert within a given or each field
6341 ## as appropriate, rather than requiring "overwrite". This makes single
6342 ## field controls that just have validation rules (eg. EMAIL) much more
6343 ## friendly. The same flag controls left shift when deleting vs just
6344 ## blanking the value, and for right-insert fields, allows right-insert
6345 ## at any non-blank (non-sign) position in the field.
6346 ## 15. Added option to use to indicate negative values for numeric controls.
6347 ## 16. Improved OnFocus handling of numeric controls.
6348 ## 17. Enhanced Home/End processing to allow operation on a field level,
6349 ## using ctrl key.
6350 ## 18. Added individual Get/Set functions for control parameters, for
6351 ## simplified integration with Boa Constructor.
6352 ## 19. Standardized "Colour" parameter names to match wxPython, with
6353 ## non-british spellings still supported for backward-compatibility.
6354 ## 20. Added '&' mask specification character for punctuation only (no letters
6355 ## or digits).
6356 ## 21. Added (in a separate file) wx.MaskedCtrl() factory function to provide
6357 ## unified interface to the masked edit subclasses.
6358 ##
6359 ##
6360 ## Version 1.3
6361 ## 1. Made it possible to configure grouping, decimal and shift-decimal characters,
6362 ## to make controls more usable internationally.
6363 ## 2. Added code to smart "adjust" value strings presented to .SetValue()
6364 ## for right-aligned numeric format controls if they are shorter than
6365 ## than the control width, prepending the missing portion, prepending control
6366 ## template left substring for the missing characters, so that setting
6367 ## numeric values is easier.
6368 ## 3. Renamed SetMaskParameters SetCtrlParameters() (with old name preserved
6369 ## for b-c), as this makes more sense.
6370 ##
6371 ## Version 1.2
6372 ## 1. Fixed .SetValue() to replace the current value, rather than the current
6373 ## selection. Also changed it to generate ValueError if presented with
6374 ## either a value which doesn't follow the format or won't fit. Also made
6375 ## set value adjust numeric and date controls as if user entered the value.
6376 ## Expanded doc explaining how SetValue() works.
6377 ## 2. Fixed EUDATE* autoformats, fixed IsDateType mask list, and added ability to
6378 ## use 3-char months for dates, and EUDATETIME, and EUDATEMILTIME autoformats.
6379 ## 3. Made all date autoformats automatically pick implied "datestyle".
6380 ## 4. Added IsModified override, since base wx.TextCtrl never reports modified if
6381 ## .SetValue used to change the value, which is what the masked edit controls
6382 ## use internally.
6383 ## 5. Fixed bug in date position adjustment on 2 to 4 digit date conversion when
6384 ## using tab to "leave field" and auto-adjust.
6385 ## 6. Fixed bug in _isCharAllowed() for negative number insertion on pastes,
6386 ## and bug in ._Paste() that didn't account for signs in signed masks either.
6387 ## 7. Fixed issues with _adjustPos for right-insert fields causing improper
6388 ## selection/replacement of values
6389 ## 8. Fixed _OnHome handler to properly handle extending current selection to
6390 ## beginning of control.
6391 ## 9. Exposed all (valid) autoformats to demo, binding descriptions to
6392 ## autoformats.
6393 ## 10. Fixed a couple of bugs in email regexp.
6394 ## 11. Made maskchardict an instance var, to make mask chars to be more
6395 ## amenable to international use.
6396 ## 12. Clarified meaning of '-' formatcode in doc.
6397 ## 13. Fixed a couple of coding bugs being flagged by Python2.1.
6398 ## 14. Fixed several issues with sign positioning, erasure and validity
6399 ## checking for "numeric" masked controls.
6400 ## 15. Added validation to IpAddrCtrl.SetValue().
6401 ##
6402 ## Version 1.1
6403 ## 1. Changed calling interface to use boolean "useFixedWidthFont" (True by default)
6404 ## vs. literal font facename, and use wxTELETYPE as the font family
6405 ## if so specified.
6406 ## 2. Switched to use of dbg module vs. locally defined version.
6407 ## 3. Revamped entire control structure to use Field classes to hold constraint
6408 ## and formatting data, to make code more hierarchical, allow for more
6409 ## sophisticated masked edit construction.
6410 ## 4. Better strategy for managing options, and better validation on keywords.
6411 ## 5. Added 'V' format code, which requires that in order for a character
6412 ## to be accepted, it must result in a string that passes the validRegex.
6413 ## 6. Added 'S' format code which means "select entire field when navigating
6414 ## to new field."
6415 ## 7. Added 'r' format code to allow "right-insert" fields. (implies 'R'--right-alignment)
6416 ## 8. Added '<' format code to allow fields to require explicit cursor movement
6417 ## to leave field.
6418 ## 9. Added validFunc option to other validation mechanisms, that allows derived
6419 ## classes to add dynamic validation constraints to the control.
6420 ## 10. Fixed bug in validatePaste code causing possible IndexErrors, and also
6421 ## fixed failure to obey case conversion codes when pasting.
6422 ## 11. Implemented '0' (zero-pad) formatting code, as it wasn't being done anywhere...
6423 ## 12. Removed condition from OnDecimalPoint, so that it always truncates right on '.'
6424 ## 13. Enhanced IpAddrCtrl to use right-insert fields, selection on field traversal,
6425 ## individual field validation to prevent field values > 255, and require explicit
6426 ## tab/. to change fields.
6427 ## 14. Added handler for left double-click to select field under cursor.
6428 ## 15. Fixed handling for "Read-only" styles.
6429 ## 16. Separated signedForegroundColor from 'R' style, and added foregroundColor
6430 ## attribute, for more consistent and controllable coloring.
6431 ## 17. Added retainFieldValidation parameter, allowing top-level constraints
6432 ## such as "validRequired" to be set independently of field-level equivalent.
6433 ## (needed in TimeCtrl for bounds constraints.)
6434 ## 18. Refactored code a bit, cleaned up and commented code more heavily, fixed
6435 ## some of the logic for setting/resetting parameters, eg. fillChar, defaultValue,
6436 ## etc.
6437 ## 19. Fixed maskchar setting for upper/lowercase, to work in all locales.
6438 ##
6439 ##
6440 ## Version 1.0
6441 ## 1. Decimal point behavior restored for decimal and integer type controls:
6442 ## decimal point now trucates the portion > 0.
6443 ## 2. Return key now works like the tab character and moves to the next field,
6444 ## provided no default button is set for the form panel on which the control
6445 ## resides.
6446 ## 3. Support added in _FindField() for subclasses controls (like timecontrol)
6447 ## to determine where the current insertion point is within the mask (i.e.
6448 ## which sub-'field'). See method documentation for more info and examples.
6449 ## 4. Added Field class and support for all constraints to be field-specific
6450 ## in addition to being globally settable for the control.
6451 ## Choices for each field are validated for length and pastability into
6452 ## the field in question, raising ValueError if not appropriate for the control.
6453 ## Also added selective additional validation based on individual field constraints.
6454 ## By default, SHIFT-WXK_DOWN, SHIFT-WXK_UP, WXK_PRIOR and WXK_NEXT all
6455 ## auto-complete fields with choice lists, supplying the 1st entry in
6456 ## the choice list if the field is empty, and cycling through the list in
6457 ## the appropriate direction if already a match. WXK_DOWN will also auto-
6458 ## complete if the field is partially completed and a match can be made.
6459 ## SHIFT-WXK_UP/DOWN will also take you to the next field after any
6460 ## auto-completion performed.
6461 ## 5. Added autoCompleteKeycodes=[] parameters for allowing further
6462 ## customization of the control. Any keycode supplied as a member
6463 ## of the _autoCompleteKeycodes list will be treated like WXK_NEXT. If
6464 ## requireFieldChoice is set, then a valid value from each non-empty
6465 ## choice list will be required for the value of the control to validate.
6466 ## 6. Fixed "auto-sizing" to be relative to the font actually used, rather
6467 ## than making assumptions about character width.
6468 ## 7. Fixed GetMaskParameter(), which was non-functional in previous version.
6469 ## 8. Fixed exceptions raised to provide info on which control had the error.
6470 ## 9. Fixed bug in choice management of MaskedComboBox.
6471 ## 10. Fixed bug in IpAddrCtrl causing traceback if field value was of
6472 ## the form '# #'. Modified control code for IpAddrCtrl so that '.'
6473 ## in the middle of a field clips the rest of that field, similar to
6474 ## decimal and integer controls.
6475 ##
6476 ##
6477 ## Version 0.0.7
6478 ## 1. "-" is a toggle for sign; "+" now changes - signed numerics to positive.
6479 ## 2. ',' in formatcodes now causes numeric values to be comma-delimited (e.g.333,333).
6480 ## 3. New support for selecting text within the control.(thanks Will Sadkin!)
6481 ## Shift-End and Shift-Home now select text as you would expect
6482 ## Control-Shift-End selects to the end of the mask string, even if value not entered.
6483 ## Control-A selects all *entered* text, Shift-Control-A selects everything in the control.
6484 ## 4. event.Skip() added to onKillFocus to correct remnants when running in Linux (contributed-
6485 ## for some reason I couldn't find the original email but thanks!!!)
6486 ## 5. All major key-handling code moved to their own methods for easier subclassing: OnHome,
6487 ## OnErase, OnEnd, OnCtrl_X, OnCtrl_A, etc.
6488 ## 6. Email and autoformat validations corrected using regex provided by Will Sadkin (thanks!).
6489 ## (The rest of the changes in this version were done by Will Sadkin with permission from Jeff...)
6490 ## 7. New mechanism for replacing default behavior for any given key, using
6491 ## ._SetKeycodeHandler(keycode, func) and ._SetKeyHandler(char, func) now available
6492 ## for easier subclassing of the control.
6493 ## 8. Reworked the delete logic, cut, paste and select/replace logic, as well as some bugs
6494 ## with insertion point/selection modification. Changed Ctrl-X to use standard "cut"
6495 ## semantics, erasing the selection, rather than erasing the entire control.
6496 ## 9. Added option for an "default value" (ie. the template) for use when a single fillChar
6497 ## is not desired in every position. Added IsDefault() function to mean "does the value
6498 ## equal the template?" and modified .IsEmpty() to mean "do all of the editable
6499 ## positions in the template == the fillChar?"
6500 ## 10. Extracted mask logic into mixin, so we can have both MaskedTextCtrl and MaskedComboBox,
6501 ## now included.
6502 ## 11. MaskedComboBox now adds the capability to validate from list of valid values.
6503 ## Example: City validates against list of cities, or zip vs zip code list.
6504 ## 12. Fixed oversight in EVT_TEXT handler that prevented the events from being
6505 ## passed to the next handler in the event chain, causing updates to the
6506 ## control to be invisible to the parent code.
6507 ## 13. Added IPADDR autoformat code, and subclass IpAddrCtrl for controlling tabbing within
6508 ## the control, that auto-reformats as you move between cells.
6509 ## 14. Mask characters [A,a,X,#] can now appear in the format string as literals, by using '\'.
6510 ## 15. It is now possible to specify repeating masks, e.g. #{3}-#{3}-#{14}
6511 ## 16. Fixed major bugs in date validation, due to the fact that
6512 ## wxDateTime.ParseDate is too liberal, and will accept any form that
6513 ## makes any kind of sense, regardless of the datestyle you specified
6514 ## for the control. Unfortunately, the strategy used to fix it only
6515 ## works for versions of wxPython post 2.3.3.1, as a C++ assert box
6516 ## seems to show up on an invalid date otherwise, instead of a catchable
6517 ## exception.
6518 ## 17. Enhanced date adjustment to automatically adjust heuristic based on
6519 ## current year, making last century/this century determination on
6520 ## 2-digit year based on distance between today's year and value;
6521 ## if > 50 year separation, assume last century (and don't assume last
6522 ## century is 20th.)
6523 ## 18. Added autoformats and support for including HHMMSS as well as HHMM for
6524 ## date times, and added similar time, and militaray time autoformats.
6525 ## 19. Enhanced tabbing logic so that tab takes you to the next field if the
6526 ## control is a multi-field control.
6527 ## 20. Added stub method called whenever the control "changes fields", that
6528 ## can be overridden by subclasses (eg. IpAddrCtrl.)
6529 ## 21. Changed a lot of code to be more functionally-oriented so side-effects
6530 ## aren't as problematic when maintaining code and/or adding features.
6531 ## Eg: IsValid() now does not have side-effects; it merely reflects the
6532 ## validity of the value of the control; to determine validity AND recolor
6533 ## the control, _CheckValid() should be used with a value argument of None.
6534 ## Similarly, made most reformatting function take an optional candidate value
6535 ## rather than just using the current value of the control, and only
6536 ## have them change the value of the control if a candidate is not specified.
6537 ## In this way, you can do validation *before* changing the control.
6538 ## 22. Changed validRequired to mean "disallow chars that result in invalid
6539 ## value." (Old meaning now represented by emptyInvalid.) (This was
6540 ## possible once I'd made the changes in (19) above.)
6541 ## 23. Added .SetMaskParameters and .GetMaskParameter methods, so they
6542 ## can be set/modified/retrieved after construction. Removed individual
6543 ## parameter setting functions, in favor of this mechanism, so that
6544 ## all adjustment of the control based on changing parameter values can
6545 ## be handled in one place with unified mechanism.
6546 ## 24. Did a *lot* of testing and fixing re: numeric values. Added ability
6547 ## to type "grouping char" (ie. ',') and validate as appropriate.
6548 ## 25. Fixed ZIPPLUS4 to allow either 5 or 4, but if > 5 must be 9.
6549 ## 26. Fixed assumption about "decimal or integer" masks so that they're only
6550 ## made iff there's no validRegex associated with the field. (This
6551 ## is so things like zipcodes which look like integers can have more
6552 ## restrictive validation (ie. must be 5 digits.)
6553 ## 27. Added a ton more doc strings to explain use and derivation requirements
6554 ## and did regularization of the naming conventions.
6555 ## 28. Fixed a range bug in _adjustKey preventing z from being handled properly.
6556 ## 29. Changed behavior of '.' (and shift-.) in numeric controls to move to
6557 ## reformat the value and move the next field as appropriate. (shift-'.',
6558 ## ie. '>' moves to the previous field.
6559
6560 ## Version 0.0.6
6561 ## 1. Fixed regex bug that caused autoformat AGE to invalidate any age ending
6562 ## in '0'.
6563 ## 2. New format character 'D' to trigger date type. If the user enters 2 digits in the
6564 ## year position, the control will expand the value to four digits, using numerals below
6565 ## 50 as 21st century (20+nn) and less than 50 as 20th century (19+nn).
6566 ## Also, new optional parameter datestyle = set to one of {MDY|DMY|YDM}
6567 ## 3. revalid parameter renamed validRegex to conform to standard for all validation
6568 ## parameters (see 2 new ones below).
6569 ## 4. New optional init parameter = validRange. Used only for int/dec (numeric) types.
6570 ## Allows the developer to specify a valid low/high range of values.
6571 ## 5. New optional init parameter = validList. Used for character types. Allows developer
6572 ## to send a list of values to the control to be used for specific validation.
6573 ## See the Last Name Only example - it is list restricted to Smith/Jones/Williams.
6574 ## 6. Date type fields now use wxDateTime's parser to validate the date and time.
6575 ## This works MUCH better than my kludgy regex!! Thanks to Robin Dunn for pointing
6576 ## me toward this solution!
6577 ## 7. Date fields now automatically expand 2-digit years when it can. For example,
6578 ## if the user types "03/10/67", then "67" will auto-expand to "1967". If a two-year
6579 ## date is entered it will be expanded in any case when the user tabs out of the
6580 ## field.
6581 ## 8. New class functions: SetValidBackgroundColor, SetInvalidBackgroundColor, SetEmptyBackgroundColor,
6582 ## SetSignedForeColor allow accessto override default class coloring behavior.
6583 ## 9. Documentation updated and improved.
6584 ## 10. Demo - page 2 is now a wxFrame class instead of a wxPyApp class. Works better.
6585 ## Two new options (checkboxes) - test highlight empty and disallow empty.
6586 ## 11. Home and End now work more intuitively, moving to the first and last user-entry
6587 ## value, respectively.
6588 ## 12. New class function: SetRequired(bool). Sets the control's entry required flag
6589 ## (i.e. disallow empty values if True).
6590 ##
6591 ## Version 0.0.5
6592 ## 1. get_plainValue method renamed to GetPlainValue following the wxWindows
6593 ## StudlyCaps(tm) standard (thanks Paul Moore). ;)
6594 ## 2. New format code 'F' causes the control to auto-fit (auto-size) itself
6595 ## based on the length of the mask template.
6596 ## 3. Class now supports "autoformat" codes. These can be passed to the class
6597 ## on instantiation using the parameter autoformat="code". If the code is in
6598 ## the dictionary, it will self set the mask, formatting, and validation string.
6599 ## I have included a number of samples, but I am hoping that someone out there
6600 ## can help me to define a whole bunch more.
6601 ## 4. I have added a second page to the demo (as well as a second demo class, test2)
6602 ## to showcase how autoformats work. The way they self-format and self-size is,
6603 ## I must say, pretty cool.
6604 ## 5. Comments added and some internal cosmetic revisions re: matching the code
6605 ## standards for class submission.
6606 ## 6. Regex validation is now done in real time - field turns yellow immediately
6607 ## and stays yellow until the entered value is valid
6608 ## 7. Cursor now skips over template characters in a more intuitive way (before the
6609 ## next keypress).
6610 ## 8. Change, Keypress and LostFocus methods added for convenience of subclasses.
6611 ## Developer may use these methods which will be called after EVT_TEXT, EVT_CHAR,
6612 ## and EVT_KILL_FOCUS, respectively.
6613 ## 9. Decimal and numeric handlers have been rewritten and now work more intuitively.
6614 ##
6615 ## Version 0.0.4
6616 ## 1. New .IsEmpty() method returns True if the control's value is equal to the
6617 ## blank template string
6618 ## 2. Control now supports a new init parameter: revalid. Pass a regular expression
6619 ## that the value will have to match when the control loses focus. If invalid,
6620 ## the control's BackgroundColor will turn yellow, and an internal flag is set (see next).
6621 ## 3. Demo now shows revalid functionality. Try entering a partial value, such as a
6622 ## partial social security number.
6623 ## 4. New .IsValid() value returns True if the control is empty, or if the value matches
6624 ## the revalid expression. If not, .IsValid() returns False.
6625 ## 5. Decimal values now collapse to decimal with '.00' on losefocus if the user never
6626 ## presses the decimal point.
6627 ## 6. Cursor now goes to the beginning of the field if the user clicks in an
6628 ## "empty" field intead of leaving the insertion point in the middle of the
6629 ## field.
6630 ## 7. New "N" mask type includes upper and lower chars plus digits. a-zA-Z0-9.
6631 ## 8. New formatcodes init parameter replaces other init params and adds functions.
6632 ## String passed to control on init controls:
6633 ## _ Allow spaces
6634 ## ! Force upper
6635 ## ^ Force lower
6636 ## R Show negative #s in red
6637 ## , Group digits
6638 ## - Signed numerals
6639 ## 0 Numeric fields get leading zeros
6640 ## 9. Ctrl-X in any field clears the current value.
6641 ## 10. Code refactored and made more modular (esp in OnChar method). Should be more
6642 ## easy to read and understand.
6643 ## 11. Demo enhanced.
6644 ## 12. Now has _doc_.
6645 ##
6646 ## Version 0.0.3
6647 ## 1. GetPlainValue() now returns the value without the template characters;
6648 ## so, for example, a social security number (123-33-1212) would return as
6649 ## 123331212; also removes white spaces from numeric/decimal values, so
6650 ## "- 955.32" is returned "-955.32". Press ctrl-S to see the plain value.
6651 ## 2. Press '.' in an integer style masked control and truncate any trailing digits.
6652 ## 3. Code moderately refactored. Internal names improved for clarity. Additional
6653 ## internal documentation.
6654 ## 4. Home and End keys now supported to move cursor to beginning or end of field.
6655 ## 5. Un-signed integers and decimals now supported.
6656 ## 6. Cosmetic improvements to the demo.
6657 ## 7. Class renamed to MaskedTextCtrl.
6658 ## 8. Can now specify include characters that will override the basic
6659 ## controls: for example, includeChars = "@." for email addresses
6660 ## 9. Added mask character 'C' -> allow any upper or lowercase character
6661 ## 10. .SetSignColor(str:color) sets the foreground color for negative values
6662 ## in signed controls (defaults to red)
6663 ## 11. Overview documentation written.
6664 ##
6665 ## Version 0.0.2
6666 ## 1. Tab now works properly when pressed in last position
6667 ## 2. Decimal types now work (e.g. #####.##)
6668 ## 3. Signed decimal or numeric values supported (i.e. negative numbers)
6669 ## 4. Negative decimal or numeric values now can show in red.
6670 ## 5. Can now specify an "exclude list" with the excludeChars parameter.
6671 ## See date/time formatted example - you can only enter A or P in the
6672 ## character mask space (i.e. AM/PM).
6673 ## 6. Backspace now works properly, including clearing data from a selected
6674 ## region but leaving template characters intact. Also delete key.
6675 ## 7. Left/right arrows now work properly.
6676 ## 8. Removed EventManager call from test so demo should work with wxPython 2.3.3
6677 ##
