-<b>Masked Edit Overview:
-=====================</b>
-<b>MaskedTextCtrl</b>
- is a sublassed text control that can carefully control the user's input
- based on a mask string you provide.
-
- General usage example:
- control = MaskedTextCtrl( win, -1, '', mask = '(###) ###-####')
-
- The example above will create a text control that allows only numbers to be
- entered and then only in the positions indicated in the mask by the # sign.
-
-<b>MaskedComboBox</b>
- is a similar subclass of wxComboBox that allows the same sort of masking,
- but also can do auto-complete of values, and can require the value typed
- to be in the list of choices to be colored appropriately.
-
-<b>wxMaskedCtrl</b>
- is actually a factory function for several types of masked edit controls:
-
- <b>MaskedTextCtrl</b> - standard masked edit text box
- <b>MaskedComboBox</b> - adds combobox capabilities
- <b>IpAddrCtrl</b> - adds special semantics for IP address entry
- <b>TimeCtrl</b> - special subclass handling lots of types as values
- <b>wxMaskedNumCtrl</b> - special subclass handling numeric values
-
- It works by looking for a <b><i>controlType</i></b> parameter in the keyword
- arguments of the control, to determine what kind of instance to return.
- If not specified as a keyword argument, the default control type returned
- will be MaskedTextCtrl.
-
- Each of the above classes has its own set of arguments, but wxMaskedCtrl
- provides a single "unified" interface for masked controls. Those for
- MaskedTextCtrl, MaskedComboBox and IpAddrCtrl are all documented
- below; the others have their own demo pages and interface descriptions.
- (See end of following discussion for how to configure the wxMaskedCtrl()
- to select the above control types.)
-
-
-<b>INITILIZATION PARAMETERS
-========================
-mask=</b>
-Allowed mask characters and function:
- Character Function
- # Allow numeric only (0-9)
- N Allow letters and numbers (0-9)
- A Allow uppercase letters only
- a Allow lowercase letters only
- C Allow any letter, upper or lower
- X Allow string.letters, string.punctuation, string.digits
- & Allow string.punctuation only
-
-
- These controls define these sets of characters using string.letters,
- string.uppercase, etc. These sets are affected by the system locale
- setting, so in order to have the masked controls accept characters
- that are specific to your users' language, your application should
- set the locale.
- For example, to allow international characters to be used in the
- above masks, you can place the following in your code as part of
- your application's initialization code:
-
- import locale
- locale.setlocale(locale.LC_ALL, '')
-
-
- Using these mask characters, a variety of template masks can be built. See
- the demo for some other common examples include date+time, social security
- number, etc. If any of these characters are needed as template rather
- than mask characters, they can be escaped with \, ie. \N means "literal N".
- (use \\ for literal backslash, as in: r'CCC\\NNN'.)
-
-
- <b>Note:</b>
- Masks containing only # characters and one optional decimal point
- character are handled specially, as "numeric" controls. Such
- controls have special handling for typing the '-' key, handling
- the "decimal point" character as truncating the integer portion,
- optionally allowing grouping characters and so forth.
- There are several parameters and format codes that only make sense
- when combined with such masks, eg. groupChar, decimalChar, and so
- forth (see below). These allow you to construct reasonable
- numeric entry controls.
-
- <b>Note:</b>
- Changing the mask for a control deletes any previous field classes
- (and any associated validation or formatting constraints) for them.
-
-<b>useFixedWidthFont=</b>
- By default, masked edit controls use a fixed width font, so that
- the mask characters are fixed within the control, regardless of
- subsequent modifications to the value. Set to False if having
- the control font be the same as other controls is required.
-
-
-<b>formatcodes=</b>
- These other properties can be passed to the class when instantiating it:
- Formatcodes are specified as a string of single character formatting
- codes that modify behavior of the control:
- _ Allow spaces
- ! Force upper
- ^ Force lower
- R Right-align field(s)
- r Right-insert in field(s) (implies R)
- < Stay in field until explicit navigation out of it
-
- > Allow insert/delete within partially filled fields (as
- opposed to the default "overwrite" mode for fixed-width
- masked edit controls.) This allows single-field controls
- or each field within a multi-field control to optionally
- behave more like standard text controls.
- (See EMAIL or phone number autoformat examples.)
-
- <i>Note: This also governs whether backspace/delete operations
- shift contents of field to right of cursor, or just blank the
- erased section.
-
- Also, when combined with 'r', this indicates that the field
- or control allows right insert anywhere within the current
- non-empty value in the field. (Otherwise right-insert behavior
- is only performed to when the entire right-insertable field is
- selected or the cursor is at the right edge of the field.</i>
-
-
- , Allow grouping character in integer fields of numeric controls
- and auto-group/regroup digits (if the result fits) when leaving
- such a field. (If specified, .SetValue() will attempt to
- auto-group as well.)
- ',' is also the default grouping character. To change the
- grouping character and/or decimal character, use the groupChar
- and decimalChar parameters, respectively.
- Note: typing the "decimal point" character in such fields will
- clip the value to that left of the cursor for integer
- fields of controls with "integer" or "floating point" masks.
- If the ',' format code is specified, this will also cause the
- resulting digits to be regrouped properly, using the current
- grouping character.
- - Prepend and reserve leading space for sign to mask and allow
- signed values (negative #s shown in red by default.) Can be
- used with argument useParensForNegatives (see below.)
- 0 integer fields get leading zeros
- D Date[/time] field
- T Time field
- F Auto-Fit: the control calulates its size from
- the length of the template mask
- V validate entered chars against validRegex before allowing them
- to be entered vs. being allowed by basic mask and then having
- the resulting value just colored as invalid.
- (See USSTATE autoformat demo for how this can be used.)
- S select entire field when navigating to new field
-
-<b>fillChar=
-defaultValue=</b>
- These controls have two options for the initial state of the control.
- If a blank control with just the non-editable characters showing
- is desired, simply leave the constructor variable fillChar as its
- default (' '). If you want some other character there, simply
- change the fillChar to that value. Note: changing the control's fillChar
- will implicitly reset all of the fields' fillChars to this value.
-
- If you need different default characters in each mask position,
- you can specify a defaultValue parameter in the constructor, or
- set them for each field individually.
- This value must satisfy the non-editable characters of the mask,
- but need not conform to the replaceable characters.
-
-<b>groupChar=
-decimalChar=</b>
- These parameters govern what character is used to group numbers
- and is used to indicate the decimal point for numeric format controls.
- The default groupChar is ',', the default decimalChar is '.'
- By changing these, you can customize the presentation of numbers
- for your location.
- eg: formatcodes = ',', groupChar="'" allows 12'345.34
- formatcodes = ',', groupChar='.', decimalChar=',' allows 12.345,34
-
-<b>shiftDecimalChar=</b>
- The default "shiftDecimalChar" (used for "backwards-tabbing" until
- shift-tab is fixed in wxPython) is '>' (for QUERTY keyboards.) for
- other keyboards, you may want to customize this, eg '?' for shift ',' on
- AZERTY keyboards, ':' or ';' for other European keyboards, etc.
-
-<b>useParensForNegatives=False</b>
- This option can be used with signed numeric format controls to
- indicate signs via () rather than '-'.
-
-<b>autoSelect=False</b>
- This option can be used to have a field or the control try to
- auto-complete on each keystroke if choices have been specified.
-
-<b>autoCompleteKeycodes=[]</b>
- By default, DownArrow, PageUp and PageDown will auto-complete a
- partially entered field. Shift-DownArrow, Shift-UpArrow, PageUp
- and PageDown will also auto-complete, but if the field already
- contains a matched value, these keys will cycle through the list
- of choices forward or backward as appropriate. Shift-Up and
- Shift-Down also take you to the next/previous field after any
- auto-complete action.
-
- Additional auto-complete keys can be specified via this parameter.
- Any keys so specified will act like PageDown.
-
-
-
-<b>Validating User Input:
-======================</b>
- There are a variety of initialization parameters that are used to validate
- user input. These parameters can apply to the control as a whole, and/or
- to individual fields:
-
- excludeChars= A string of characters to exclude even if otherwise allowed
- includeChars= A string of characters to allow even if otherwise disallowed
- validRegex= Use a regular expression to validate the contents of the text box
- validRange= Pass a rangeas list (low,high) to limit numeric fields/values
- choices= A list of strings that are allowed choices for the control.
- choiceRequired= value must be member of choices list
- compareNoCase= Perform case-insensitive matching when validating against list
- <i>Note: for MaskedComboBox, this defaults to True.</i>
- emptyInvalid= Boolean indicating whether an empty value should be considered invalid
-
- validFunc= A function to call of the form: bool = func(candidate_value)
- which will return True if the candidate_value satisfies some
- external criteria for the control in addition to the the
- other validation, or False if not. (This validation is
- applied last in the chain of validations.)
-
- validRequired= Boolean indicating whether or not keys that are allowed by the
- mask, but result in an invalid value are allowed to be entered
- into the control. Setting this to True implies that a valid
- default value is set for the control.
-
- retainFieldValidation=
- False by default; if True, this allows individual fields to
- retain their own validation constraints independently of any
- subsequent changes to the control's overall parameters.
-
- validator= Validators are not normally needed for masked controls, because
- of the nature of the validation and control of input. However,
- you can supply one to provide data transfer routines for the
- controls.
-
-
-<b>Coloring Behavior:
-==================</b>
- The following parameters have been provided to allow you to change the default
- coloring behavior of the control. These can be set at construction, or via
- the .SetCtrlParameters() function. Pass a color as string e.g. 'Yellow':
-
- emptyBackgroundColour= Control Background color when identified as empty. Default=White
- invalidBackgroundColour= Control Background color when identified as Not valid. Default=Yellow
- validBackgroundColour= Control Background color when identified as Valid. Default=white
-
-
- The following parameters control the default foreground color coloring behavior of the
- control. Pass a color as string e.g. 'Yellow':
- foregroundColour= Control foreground color when value is not negative. Default=Black
- signedForegroundColour= Control foreground color when value is negative. Default=Red
-
-
-<b>Fields:
-=======</b>
- Each part of the mask that allows user input is considered a field. The fields
- are represented by their own class instances. You can specify field-specific
- constraints by constructing or accessing the field instances for the control
- and then specifying those constraints via parameters.
-
-<b>fields=</b>
- This parameter allows you to specify Field instances containing
- constraints for the individual fields of a control, eg: local
- choice lists, validation rules, functions, regexps, etc.
- It can be either an ordered list or a dictionary. If a list,
- the fields will be applied as fields 0, 1, 2, etc.
- If a dictionary, it should be keyed by field index.
- the values should be a instances of maskededit.Field.
-
- Any field not represented by the list or dictionary will be
- implicitly created by the control.
-
- eg:
- fields = [ Field(formatcodes='_r'), Field('choices=['a', 'b', 'c']) ]
- or
- fields = {
- 1: ( Field(formatcodes='_R', choices=['a', 'b', 'c']),
- 3: ( Field(choices=['01', '02', '03'], choiceRequired=True)
- }
-
- The following parameters are available for individual fields, with the
- same semantics as for the whole control but applied to the field in question:
-
- fillChar # if set for a field, it will override the control's fillChar for that field
- groupChar # if set for a field, it will override the control's default
- defaultValue # sets field-specific default value; overrides any default from control
- compareNoCase # overrides control's settings
- emptyInvalid # determines whether field is required to be filled at all times
- validRequired # if set, requires field to contain valid value
-
- If any of the above parameters are subsequently specified for the control as a
- whole, that new value will be propagated to each field, unless the
- retainFieldValidation control-level parameter is set.
-
- formatcodes # Augments control's settings
- excludeChars # ' ' '
- includeChars # ' ' '
- validRegex # ' ' '
- validRange # ' ' '
- choices # ' ' '
- choiceRequired # ' ' '
- validFunc # ' ' '
-
-
-
-<b>Control Class Functions:
-========================
- .GetPlainValue(value=None)</b>
- Returns the value specified (or the control's text value
- not specified) without the formatting text.
- In the example above, might return phone no='3522640075',
- whereas control.GetValue() would return '(352) 264-0075'
- <b>.ClearValue()</b>
- Returns the control's value to its default, and places the
- cursor at the beginning of the control.
- <b>.SetValue()</b>
- Does "smart replacement" of passed value into the control, as does
- the .Paste() method. As with other text entry controls, the
- .SetValue() text replacement begins at left-edge of the control,
- with missing mask characters inserted as appropriate.
- .SetValue will also adjust integer, float or date mask entry values,
- adding commas, auto-completing years, etc. as appropriate.
- For "right-aligned" numeric controls, it will also now automatically
- right-adjust any value whose length is less than the width of the
- control before attempting to set the value.
- If a value does not follow the format of the control's mask, or will
- not fit into the control, a ValueError exception will be raised.
- Eg:
- mask = '(###) ###-####'
- .SetValue('1234567890') => '(123) 456-7890'
- .SetValue('(123)4567890') => '(123) 456-7890'
- .SetValue('(123)456-7890') => '(123) 456-7890'
- .SetValue('123/4567-890') => illegal paste; ValueError
-
- mask = '#{6}.#{2}', formatcodes = '_,-',
- .SetValue('111') => ' 111 . '
- .SetValue(' %9.2f' % -111.12345 ) => ' -111.12'
- .SetValue(' %9.2f' % 1234.00 ) => ' 1,234.00'
- .SetValue(' %9.2f' % -1234567.12345 ) => insufficient room; ValueError
-
- mask = '#{6}.#{2}', formatcodes = '_,-R' # will right-adjust value for right-aligned control
- .SetValue('111') => padded value misalignment ValueError: " 111" will not fit
- .SetValue('%.2f' % 111 ) => ' 111.00'
- .SetValue('%.2f' % -111.12345 ) => ' -111.12'
-
-
- <b>.IsValid(value=None)</b>
- Returns True if the value specified (or the value of the control
- if not specified) passes validation tests
- <b>.IsEmpty(value=None)</b>
- Returns True if the value specified (or the value of the control
- if not specified) is equal to an "empty value," ie. all
- editable characters == the fillChar for their respective fields.
- <b>.IsDefault(value=None)</b>
- Returns True if the value specified (or the value of the control
- if not specified) is equal to the initial value of the control.
-
- <b>.Refresh()</b>
- Recolors the control as appropriate to its current settings.
-
- <b>.SetCtrlParameters(**kwargs)</b>
- This function allows you to set up and/or change the control parameters
- after construction; it takes a list of key/value pairs as arguments,
- where the keys can be any of the mask-specific parameters in the constructor.
- Eg:
- ctl = MaskedTextCtrl( self, -1 )
- ctl.SetCtrlParameters( mask='###-####',
- defaultValue='555-1212',
- formatcodes='F')
-
- <b>.GetCtrlParameter(parametername)</b>
- This function allows you to retrieve the current value of a parameter
- from the control.
-
- <b><i>Note:</i></b> Each of the control parameters can also be set using its
- own Set and Get function. These functions follow a regular form:
- All of the parameter names start with lower case; for their
- corresponding Set/Get function, the parameter name is capitalized.
- Eg: ctl.SetMask('###-####')
- ctl.SetDefaultValue('555-1212')
- ctl.GetChoiceRequired()
- ctl.GetFormatcodes()
-
- <b><i>Note:</i></b> After any change in parameters, the choices for the
- control are reevaluated to ensure that they are still legal. If you
- have large choice lists, it is therefore more efficient to set parameters
- before setting the choices available.
-
- <b>.SetFieldParameters(field_index, **kwargs)</b>
- This function allows you to specify change individual field
- parameters after construction. (Indices are 0-based.)
-
- <b>.GetFieldParameter(field_index, parametername)</b>
- Allows the retrieval of field parameters after construction
-
-
-The control detects certain common constructions. In order to use the signed feature
-(negative numbers and coloring), the mask has to be all numbers with optionally one
-decimal point. Without a decimal (e.g. '######', the control will treat it as an integer
-value. With a decimal (e.g. '###.##'), the control will act as a floating point control
-(i.e. press decimal to 'tab' to the decimal position). Pressing decimal in the
-integer control truncates the value. However, for a true numeric control,
-MaskedNumCtrl provides all this, and true numeric input/output support as well.
-
-
-Check your controls by calling each control's .IsValid() function and the
-.IsEmpty() function to determine which controls have been a) filled in and
-b) filled in properly.
-
-
-Regular expression validations can be used flexibly and creatively.
-Take a look at the demo; the zip-code validation succeeds as long as the
-first five numerals are entered. the last four are optional, but if
-any are entered, there must be 4 to be valid.
-
-<B>wxMaskedCtrl Configuration
-==========================</B>
-wxMaskedCtrl works by looking for a special <b><i>controlType</i></b>
-parameter in the variable arguments of the control, to determine
-what kind of instance to return.
-controlType can be one of:
-
- controlTypes.MASKEDTEXT
- controlTypes.MASKEDCOMBO
- controlTypes.IPADDR
- controlTypes.TIME
- controlTypes.NUMBER
-
-These constants are also available individually, ie, you can
-use either of the following:
-
- from wxPython.wx.lib.maskedctrl import wxMaskedCtrl, controlTypes
- from wxPython.wx.lib.maskedctrl import wxMaskedCtrl, MASKEDCOMBO, MASKEDTEXT, NUMBER
-
-If not specified as a keyword argument, the default controlType is
-controlTypes.TEXT.

-DEVELOPER COMMENTS:
-
-Naming Conventions
-------------------
- All methods of the Mixin that are not meant to be exposed to the external
- interface are prefaced with '_'. Those functions that are primarily
- intended to be internal subroutines subsequently start with a lower-case
- letter; those that are primarily intended to be used and/or overridden
- by derived subclasses start with a capital letter.
-
- The following methods must be used and/or defined when deriving a control
- from wxMaskedEditMixin. NOTE: if deriving from a *masked edit* control
- (eg. class IpAddrCtrl(MaskedTextCtrl) ), then this is NOT necessary,
- as it's already been done for you in the base class.
-
- ._SetInitialValue()
- This function must be called after the associated base
- control has been initialized in the subclass __init__
- function. It sets the initial value of the control,
- either to the value specified if non-empty, the
- default value if specified, or the "template" for
- the empty control as necessary. It will also set/reset
- the font if necessary and apply formatting to the
- control at this time.
-
- ._GetSelection()
- REQUIRED
- Each class derived from wxMaskedEditMixin must define
- the function for getting the start and end of the
- current text selection. The reason for this is
- that not all controls have the same function name for
- doing this; eg. wxTextCtrl uses .GetSelection(),
- whereas we had to write a .GetMark() function for
- wxComboBox, because .GetSelection() for the control
- gets the currently selected list item from the combo
- box, and the control doesn't (yet) natively provide
- a means of determining the text selection.
- ._SetSelection()
- REQUIRED
- Similarly to _GetSelection, each class derived from
- wxMaskedEditMixin must define the function for setting
- the start and end of the current text selection.
- (eg. .SetSelection() for MaskedTextCtrl, and .SetMark() for
- MaskedComboBox.
-
- ._GetInsertionPoint()
- ._SetInsertionPoint()
- REQUIRED
- For consistency, and because the mixin shouldn't rely
- on fixed names for any manipulations it does of any of
- the base controls, we require each class derived from
- wxMaskedEditMixin to define these functions as well.
-
- ._GetValue()
- ._SetValue() REQUIRED
- Each class derived from wxMaskedEditMixin must define
- the functions used to get and set the raw value of the
- control.
- This is necessary so that recursion doesn't take place
- when setting the value, and so that the mixin can
- call the appropriate function after doing all its
- validation and manipulation without knowing what kind
- of base control it was mixed in with. To handle undo
- functionality, the ._SetValue() must record the current
- selection prior to setting the value.
-
- .Cut()
- .Paste()
- .Undo()
- .SetValue() REQUIRED
- Each class derived from wxMaskedEditMixin must redefine
- these functions to call the _Cut(), _Paste(), _Undo()
- and _SetValue() methods, respectively for the control,
- so as to prevent programmatic corruption of the control's
- value. This must be done in each derivation, as the
- mixin cannot itself override a member of a sibling class.
-
- ._Refresh() REQUIRED
- Each class derived from wxMaskedEditMixin must define
- the function used to refresh the base control.
-
- .Refresh() REQUIRED
- Each class derived from wxMaskedEditMixin must redefine
- this function so that it checks the validity of the
- control (via self._CheckValid) and then refreshes
- control using the base class method.
-
- ._IsEditable() REQUIRED
- Each class derived from wxMaskedEditMixin must define
- the function used to determine if the base control is
- editable or not. (For MaskedComboBox, this has to
- be done with code, rather than specifying the proper
- function in the base control, as there isn't one...)
- ._CalcSize() REQUIRED
- Each class derived from wxMaskedEditMixin must define
- the function used to determine how wide the control
- should be given the mask. (The mixin function
- ._calcSize() provides a baseline estimate.)
-
-
-Event Handling
---------------
- Event handlers are "chained", and wxMaskedEditMixin usually
- swallows most of the events it sees, thereby preventing any other
- handlers from firing in the chain. It is therefore required that
- each class derivation using the mixin to have an option to hook up
- the event handlers itself or forego this operation and let a
- subclass of the masked control do so. For this reason, each
- subclass should probably include the following code:
-
- if setupEventHandling:
- ## Setup event handlers
- EVT_SET_FOCUS( self, self._OnFocus ) ## defeat automatic full selection
- EVT_KILL_FOCUS( self, self._OnKillFocus ) ## run internal validator
- EVT_LEFT_DCLICK(self, self._OnDoubleClick) ## select field under cursor on dclick
- EVT_RIGHT_UP(self, self._OnContextMenu ) ## bring up an appropriate context menu
- EVT_KEY_DOWN( self, self._OnKeyDown ) ## capture control events not normally seen, eg ctrl-tab.
- EVT_CHAR( self, self._OnChar ) ## handle each keypress
- EVT_TEXT( self, self.GetId(), self._OnTextChange ) ## color control appropriately & keep
- ## track of previous value for undo
-
- where setupEventHandling is an argument to its constructor.
-
- These 5 handlers must be "wired up" for the wxMaskedEdit
- control to provide default behavior. (The setupEventHandling
- is an argument to MaskedTextCtrl and MaskedComboBox, so
- that controls derived from *them* may replace one of these
- handlers if they so choose.)
-
- If your derived control wants to preprocess events before
- taking action, it should then set up the event handling itself,
- so it can be first in the event handler chain.
-
-
- The following routines are available to facilitate changing
- the default behavior of wxMaskedEdit controls:
-
- ._SetKeycodeHandler(keycode, func)
- ._SetKeyHandler(char, func)
- Use to replace default handling for any given keycode.
- func should take the key event as argument and return
- False if no further action is required to handle the
- key. Eg:
- self._SetKeycodeHandler(WXK_UP, self.IncrementValue)
- self._SetKeyHandler('-', self._OnChangeSign)
-
- "Navigation" keys are assumed to change the cursor position, and
- therefore don't cause automatic motion of the cursor as insertable
- characters do.
-
- ._AddNavKeycode(keycode, handler=None)
- ._AddNavKey(char, handler=None)
- Allows controls to specify other keys (and optional handlers)
- to be treated as navigational characters. (eg. '.' in IpAddrCtrl)
-
- ._GetNavKeycodes() Returns the current list of navigational keycodes.
-
- ._SetNavKeycodes(key_func_tuples)
- Allows replacement of the current list of keycode
- processed as navigation keys, and bind associated
- optional keyhandlers. argument is a list of key/handler
- tuples. Passing a value of None for the handler in a
- given tuple indicates that default processing for the key
- is desired.
-
- ._FindField(pos) Returns the Field object associated with this position
- in the control.
-
- ._FindFieldExtent(pos, getslice=False, value=None)
- Returns edit_start, edit_end of the field corresponding
- to the specified position within the control, and
- optionally also returns the current contents of that field.
- If value is specified, it will retrieve the slice the corresponding
- slice from that value, rather than the current value of the
- control.
-
- ._AdjustField(pos)
- This is, the function that gets called for a given position
- whenever the cursor is adjusted to leave a given field.
- By default, it adjusts the year in date fields if mask is a date,
- It can be overridden by a derived class to
- adjust the value of the control at that time.
- (eg. IpAddrCtrl reformats the address in this way.)
-
- ._Change() Called by internal EVT_TEXT handler. Return False to force
- skip of the normal class change event.
- ._Keypress(key) Called by internal EVT_CHAR handler. Return False to force
- skip of the normal class keypress event.
- ._LostFocus() Called by internal EVT_KILL_FOCUS handler
-
- ._OnKeyDown(event)
- This is the default EVT_KEY_DOWN routine; it just checks for
- "navigation keys", and if event.ControlDown(), it fires the
- mixin's _OnChar() routine, as such events are not always seen
- by the "cooked" EVT_CHAR routine.
-
- ._OnChar(event) This is the main EVT_CHAR handler for the
- wxMaskedEditMixin.
-
- The following routines are used to handle standard actions
- for control keys:
- _OnArrow(event) used for arrow navigation events
- _OnCtrl_A(event) 'select all'
- _OnCtrl_C(event) 'copy' (uses base control function, as copy is non-destructive)
- _OnCtrl_S(event) 'save' (does nothing)
- _OnCtrl_V(event) 'paste' - calls _Paste() method, to do smart paste
- _OnCtrl_X(event) 'cut' - calls _Cut() method, to "erase" selection
- _OnCtrl_Z(event) 'undo' - resets value to previous value (if any)
-
- _OnChangeField(event) primarily used for tab events, but can be
- used for other keys (eg. '.' in IpAddrCtrl)
-
- _OnErase(event) used for backspace and delete
- _OnHome(event)
- _OnEnd(event)
-
- The following routine provides a hook back to any class derivations, so that
- they can react to parameter changes before any value is set/reset as a result of
- those changes. (eg. MaskedComboBox needs to detect when the choices list is
- modified, either implicitly or explicitly, so it can reset the base control
- to have the appropriate choice list *before* the initial value is reset to match.)
-
- _OnCtrlParametersChanged()
-
-Accessor Functions
-------------------
- For convenience, each class derived from MaskedEditMixin should
- define an accessors mixin, so that it exposes only those parameters
- that make sense for the derivation. This is done with an intermediate
- level of inheritance, ie:
-
- class BaseMaskedTextCtrl( TextCtrl, MaskedEditMixin ):
-
- class MaskedTextCtrl( BaseMaskedTextCtrl, MaskedEditAccessorsMixin ):
- class MaskedNumCtrl( BaseMaskedTextCtrl, MaskedNumCtrlAccessorsMixin ):
- class IpAddrCtrl( BaseMaskedTextCtrl, IpAddrCtrlAccessorsMixin ):
- class TimeCtrl( BaseMaskedTextCtrl, TimeCtrlAccessorsMixin ):
-
- etc.
-
- Each accessors mixin defines Get/Set functions for the base class parameters
- that are appropriate for that derivation.
- This allows the base classes to be "more generic," exposing the widest
- set of options, while not requiring derived classes to be so general.

-## Current Issues:
-## ===================================
-##
-## 1. WS: For some reason I don't understand, the control is generating two (2)
-## EVT_TEXT events for every one (1) .SetValue() of the underlying control.
-## I've been unsuccessful in determining why or in my efforts to make just one
-## occur. So, I've added a hack to save the last seen value from the
-## control in the EVT_TEXT handler, and if *different*, call event.Skip()
-## to propagate it down the event chain, and let the application see it.
-##
-## 2. WS: MaskedComboBox is deficient in several areas, all having to do with the
-## behavior of the underlying control that I can't fix. The problems are:
-## a) The background coloring doesn't work in the text field of the control;
-## instead, there's a only border around it that assumes the correct color.
-## b) The control will not pass WXK_TAB to the event handler, no matter what
-## I do, and there's no style wxCB_PROCESS_TAB like wxTE_PROCESS_TAB to
-## indicate that we want these events. As a result, MaskedComboBox
-## doesn't do the nice field-tabbing that MaskedTextCtrl does.
-## c) Auto-complete had to be reimplemented for the control because programmatic
-## setting of the value of the text field does not set up the auto complete
-## the way that the control processing keystrokes does. (But I think I've
-## implemented a fairly decent approximation.) Because of this the control
-## also won't auto-complete on dropdown, and there's no event I can catch
-## to work around this problem.
-## d) There is no method provided for getting the selection; the hack I've
-## implemented has its flaws, not the least of which is that due to the
-## strategy that I'm using, the paste buffer is always replaced by the
-## contents of the control's selection when in focus, on each keystroke;
-## this makes it impossible to paste anything into a MaskedComboBox
-## at the moment... :-(
-## e) The other deficient behavior, likely induced by the workaround for (d),
-## is that you can can't shift-left to select more than one character
-## at a time.
-##
-##
-## 3. WS: Controls on wxPanels don't seem to pass Shift-WXK_TAB to their
-## EVT_KEY_DOWN or EVT_CHAR event handlers. Until this is fixed in
-## wxWidgets, shift-tab won't take you backwards through the fields of
-## a MaskedTextCtrl like it should. Until then Shifted arrow keys will
-## work like shift-tab and tab ought to.
-##
-
-## To-Do's:
-## =============================##
-## 1. Add Popup list for auto-completable fields that simulates combobox on individual
-## fields. Example: City validates against list of cities, or zip vs zip code list.
-## 2. Allow optional monetary symbols (eg. $, pounds, etc.) at front of a "decimal"
-## control.
-## 3. Fix shift-left selection for MaskedComboBox.
-## 5. Transform notion of "decimal control" to be less "entire control"-centric,
-## so that monetary symbols can be included and still have the appropriate
-## semantics. (Big job, as currently written, but would make control even
-## more useful for business applications.)
-
-
-## CHANGELOG:
-## ====================
-## Version 1.5
-## (Reported) bugs fixed:
-## 1. Crash ensues if you attempt to change the mask of a read-only
-## MaskedComboBox after initial construction.
-## 2. Changed strategy of defining Get/Set property functions so that
-## these are now generated dynamically at runtime, rather than as
-## part of the class definition. (This makes it possible to have
-## more general base classes that have many more options for configuration
-## without requiring that derivations support the same options.)
-## 3. Fixed IsModified for _Paste() and _OnErase().
-##
-## Enhancements:
-## 1. Fixed "attribute function inheritance," since base control is more
-## generic than subsequent derivations, not all property functions of a
-## generic control should be exposed in those derivations. New strategy
-## uses base control classes (eg. BaseMaskedTextCtrl) that should be
-## used to derive new class types, and mixed with their own mixins to
-## only expose those attributes from the generic masked controls that
-## make sense for the derivation. (This makes Boa happier.)
-## 2. Renamed (with b-c) MILTIME autoformats to 24HRTIME, so as to be less
-## "parochial."
-##
-## Version 1.4
-## (Reported) bugs fixed:
-## 1. Right-click menu allowed "cut" operation that destroyed mask
-## (was implemented by base control)
-## 2. MaskedComboBox didn't allow .Append() of mixed-case values; all
-## got converted to lower case.
-## 3. MaskedComboBox selection didn't deal with spaces in values
-## properly when autocompleting, and didn't have a concept of "next"
-## match for handling choice list duplicates.
-## 4. Size of MaskedComboBox was always default.
-## 5. Email address regexp allowed some "non-standard" things, and wasn't
-## general enough.
-## 6. Couldn't easily reset MaskedComboBox contents programmatically.
-## 7. Couldn't set emptyInvalid during construction.
-## 8. Under some versions of wxPython, readonly comboboxes can apparently
-## return a GetInsertionPoint() result (655535), causing masked control
-## to fail.
-## 9. Specifying an empty mask caused the controls to traceback.
-## 10. Can't specify float ranges for validRange.
-## 11. '.' from within a the static portion of a restricted IP address
-## destroyed the mask from that point rightward; tab when cursor is
-## before 1st field takes cursor past that field.
-##
-## Enhancements:
-## 12. Added Ctrl-Z/Undo handling, (and implemented context-menu properly.)
-## 13. Added auto-select option on char input for masked controls with
-## choice lists.
-## 14. Added '>' formatcode, allowing insert within a given or each field
-## as appropriate, rather than requiring "overwrite". This makes single
-## field controls that just have validation rules (eg. EMAIL) much more
-## friendly. The same flag controls left shift when deleting vs just
-## blanking the value, and for right-insert fields, allows right-insert
-## at any non-blank (non-sign) position in the field.
-## 15. Added option to use to indicate negative values for numeric controls.
-## 16. Improved OnFocus handling of numeric controls.
-## 17. Enhanced Home/End processing to allow operation on a field level,
-## using ctrl key.
-## 18. Added individual Get/Set functions for control parameters, for
-## simplified integration with Boa Constructor.
-## 19. Standardized "Colour" parameter names to match wxPython, with
-## non-british spellings still supported for backward-compatibility.
-## 20. Added '&' mask specification character for punctuation only (no letters
-## or digits).
-## 21. Added (in a separate file) wxMaskedCtrl() factory function to provide
-## unified interface to the masked edit subclasses.
-##
-##
-## Version 1.3
-## 1. Made it possible to configure grouping, decimal and shift-decimal characters,
-## to make controls more usable internationally.
-## 2. Added code to smart "adjust" value strings presented to .SetValue()
-## for right-aligned numeric format controls if they are shorter than
-## than the control width, prepending the missing portion, prepending control
-## template left substring for the missing characters, so that setting
-## numeric values is easier.
-## 3. Renamed SetMaskParameters SetCtrlParameters() (with old name preserved
-## for b-c), as this makes more sense.
-##
-## Version 1.2
-## 1. Fixed .SetValue() to replace the current value, rather than the current
-## selection. Also changed it to generate ValueError if presented with
-## either a value which doesn't follow the format or won't fit. Also made
-## set value adjust numeric and date controls as if user entered the value.
-## Expanded doc explaining how SetValue() works.
-## 2. Fixed EUDATE* autoformats, fixed IsDateType mask list, and added ability to
-## use 3-char months for dates, and EUDATETIME, and EUDATEMILTIME autoformats.
-## 3. Made all date autoformats automatically pick implied "datestyle".
-## 4. Added IsModified override, since base wxTextCtrl never reports modified if
-## .SetValue used to change the value, which is what the masked edit controls
-## use internally.
-## 5. Fixed bug in date position adjustment on 2 to 4 digit date conversion when
-## using tab to "leave field" and auto-adjust.
-## 6. Fixed bug in _isCharAllowed() for negative number insertion on pastes,
-## and bug in ._Paste() that didn't account for signs in signed masks either.
-## 7. Fixed issues with _adjustPos for right-insert fields causing improper
-## selection/replacement of values
-## 8. Fixed _OnHome handler to properly handle extending current selection to
-## beginning of control.
-## 9. Exposed all (valid) autoformats to demo, binding descriptions to
-## autoformats.
-## 10. Fixed a couple of bugs in email regexp.
-## 11. Made maskchardict an instance var, to make mask chars to be more
-## amenable to international use.
-## 12. Clarified meaning of '-' formatcode in doc.
-## 13. Fixed a couple of coding bugs being flagged by Python2.1.
-## 14. Fixed several issues with sign positioning, erasure and validity
-## checking for "numeric" masked controls.
-## 15. Added validation to IpAddrCtrl.SetValue().
-##
-## Version 1.1
-## 1. Changed calling interface to use boolean "useFixedWidthFont" (True by default)
-## vs. literal font facename, and use wxTELETYPE as the font family
-## if so specified.
-## 2. Switched to use of dbg module vs. locally defined version.
-## 3. Revamped entire control structure to use Field classes to hold constraint
-## and formatting data, to make code more hierarchical, allow for more
-## sophisticated masked edit construction.
-## 4. Better strategy for managing options, and better validation on keywords.
-## 5. Added 'V' format code, which requires that in order for a character
-## to be accepted, it must result in a string that passes the validRegex.
-## 6. Added 'S' format code which means "select entire field when navigating
-## to new field."
-## 7. Added 'r' format code to allow "right-insert" fields. (implies 'R'--right-alignment)
-## 8. Added '<' format code to allow fields to require explicit cursor movement
-## to leave field.
-## 9. Added validFunc option to other validation mechanisms, that allows derived
-## classes to add dynamic validation constraints to the control.
-## 10. Fixed bug in validatePaste code causing possible IndexErrors, and also
-## fixed failure to obey case conversion codes when pasting.
-## 11. Implemented '0' (zero-pad) formatting code, as it wasn't being done anywhere...
-## 12. Removed condition from OnDecimalPoint, so that it always truncates right on '.'
-## 13. Enhanced IpAddrCtrl to use right-insert fields, selection on field traversal,
-## individual field validation to prevent field values > 255, and require explicit
-## tab/. to change fields.
-## 14. Added handler for left double-click to select field under cursor.
-## 15. Fixed handling for "Read-only" styles.
-## 16. Separated signedForegroundColor from 'R' style, and added foregroundColor
-## attribute, for more consistent and controllable coloring.
-## 17. Added retainFieldValidation parameter, allowing top-level constraints
-## such as "validRequired" to be set independently of field-level equivalent.
-## (needed in TimeCtrl for bounds constraints.)
-## 18. Refactored code a bit, cleaned up and commented code more heavily, fixed
-## some of the logic for setting/resetting parameters, eg. fillChar, defaultValue,
-## etc.
-## 19. Fixed maskchar setting for upper/lowercase, to work in all locales.
-##
-##
-## Version 1.0
-## 1. Decimal point behavior restored for decimal and integer type controls:
-## decimal point now trucates the portion > 0.
-## 2. Return key now works like the tab character and moves to the next field,
-## provided no default button is set for the form panel on which the control
-## resides.
-## 3. Support added in _FindField() for subclasses controls (like timecontrol)
-## to determine where the current insertion point is within the mask (i.e.
-## which sub-'field'). See method documentation for more info and examples.
-## 4. Added Field class and support for all constraints to be field-specific
-## in addition to being globally settable for the control.
-## Choices for each field are validated for length and pastability into
-## the field in question, raising ValueError if not appropriate for the control.
-## Also added selective additional validation based on individual field constraints.
-## By default, SHIFT-WXK_DOWN, SHIFT-WXK_UP, WXK_PRIOR and WXK_NEXT all
-## auto-complete fields with choice lists, supplying the 1st entry in
-## the choice list if the field is empty, and cycling through the list in
-## the appropriate direction if already a match. WXK_DOWN will also auto-
-## complete if the field is partially completed and a match can be made.
-## SHIFT-WXK_UP/DOWN will also take you to the next field after any
-## auto-completion performed.
-## 5. Added autoCompleteKeycodes=[] parameters for allowing further
-## customization of the control. Any keycode supplied as a member
-## of the _autoCompleteKeycodes list will be treated like WXK_NEXT. If
-## requireFieldChoice is set, then a valid value from each non-empty
-## choice list will be required for the value of the control to validate.
-## 6. Fixed "auto-sizing" to be relative to the font actually used, rather
-## than making assumptions about character width.
-## 7. Fixed GetMaskParameter(), which was non-functional in previous version.
-## 8. Fixed exceptions raised to provide info on which control had the error.
-## 9. Fixed bug in choice management of MaskedComboBox.
-## 10. Fixed bug in IpAddrCtrl causing traceback if field value was of
-## the form '# #'. Modified control code for IpAddrCtrl so that '.'
-## in the middle of a field clips the rest of that field, similar to
-## decimal and integer controls.
-##
-##
-## Version 0.0.7
-## 1. "-" is a toggle for sign; "+" now changes - signed numerics to positive.
-## 2. ',' in formatcodes now causes numeric values to be comma-delimited (e.g.333,333).
-## 3. New support for selecting text within the control.(thanks Will Sadkin!)
-## Shift-End and Shift-Home now select text as you would expect
-## Control-Shift-End selects to the end of the mask string, even if value not entered.
-## Control-A selects all *entered* text, Shift-Control-A selects everything in the control.
-## 4. event.Skip() added to onKillFocus to correct remnants when running in Linux (contributed-
-## for some reason I couldn't find the original email but thanks!!!)
-## 5. All major key-handling code moved to their own methods for easier subclassing: OnHome,
-## OnErase, OnEnd, OnCtrl_X, OnCtrl_A, etc.
-## 6. Email and autoformat validations corrected using regex provided by Will Sadkin (thanks!).
-## (The rest of the changes in this version were done by Will Sadkin with permission from Jeff...)
-## 7. New mechanism for replacing default behavior for any given key, using
-## ._SetKeycodeHandler(keycode, func) and ._SetKeyHandler(char, func) now available
-## for easier subclassing of the control.
-## 8. Reworked the delete logic, cut, paste and select/replace logic, as well as some bugs
-## with insertion point/selection modification. Changed Ctrl-X to use standard "cut"
-## semantics, erasing the selection, rather than erasing the entire control.
-## 9. Added option for an "default value" (ie. the template) for use when a single fillChar
-## is not desired in every position. Added IsDefault() function to mean "does the value
-## equal the template?" and modified .IsEmpty() to mean "do all of the editable
-## positions in the template == the fillChar?"
-## 10. Extracted mask logic into mixin, so we can have both MaskedTextCtrl and MaskedComboBox,
-## now included.
-## 11. MaskedComboBox now adds the capability to validate from list of valid values.
-## Example: City validates against list of cities, or zip vs zip code list.
-## 12. Fixed oversight in EVT_TEXT handler that prevented the events from being
-## passed to the next handler in the event chain, causing updates to the
-## control to be invisible to the parent code.
-## 13. Added IPADDR autoformat code, and subclass IpAddrCtrl for controlling tabbing within
-## the control, that auto-reformats as you move between cells.
-## 14. Mask characters [A,a,X,#] can now appear in the format string as literals, by using '\'.
-## 15. It is now possible to specify repeating masks, e.g. #{3}-#{3}-#{14}
-## 16. Fixed major bugs in date validation, due to the fact that
-## wxDateTime.ParseDate is too liberal, and will accept any form that
-## makes any kind of sense, regardless of the datestyle you specified
-## for the control. Unfortunately, the strategy used to fix it only
-## works for versions of wxPython post 2.3.3.1, as a C++ assert box
-## seems to show up on an invalid date otherwise, instead of a catchable
-## exception.
-## 17. Enhanced date adjustment to automatically adjust heuristic based on
-## current year, making last century/this century determination on
-## 2-digit year based on distance between today's year and value;
-## if > 50 year separation, assume last century (and don't assume last
-## century is 20th.)
-## 18. Added autoformats and support for including HHMMSS as well as HHMM for
-## date times, and added similar time, and militaray time autoformats.
-## 19. Enhanced tabbing logic so that tab takes you to the next field if the
-## control is a multi-field control.
-## 20. Added stub method called whenever the control "changes fields", that
-## can be overridden by subclasses (eg. IpAddrCtrl.)
-## 21. Changed a lot of code to be more functionally-oriented so side-effects
-## aren't as problematic when maintaining code and/or adding features.
-## Eg: IsValid() now does not have side-effects; it merely reflects the
-## validity of the value of the control; to determine validity AND recolor
-## the control, _CheckValid() should be used with a value argument of None.
-## Similarly, made most reformatting function take an optional candidate value
-## rather than just using the current value of the control, and only
-## have them change the value of the control if a candidate is not specified.
-## In this way, you can do validation *before* changing the control.
-## 22. Changed validRequired to mean "disallow chars that result in invalid
-## value." (Old meaning now represented by emptyInvalid.) (This was
-## possible once I'd made the changes in (19) above.)
-## 23. Added .SetMaskParameters and .GetMaskParameter methods, so they
-## can be set/modified/retrieved after construction. Removed individual
-## parameter setting functions, in favor of this mechanism, so that
-## all adjustment of the control based on changing parameter values can
-## be handled in one place with unified mechanism.
-## 24. Did a *lot* of testing and fixing re: numeric values. Added ability
-## to type "grouping char" (ie. ',') and validate as appropriate.
-## 25. Fixed ZIPPLUS4 to allow either 5 or 4, but if > 5 must be 9.
-## 26. Fixed assumption about "decimal or integer" masks so that they're only
-## made iff there's no validRegex associated with the field. (This
-## is so things like zipcodes which look like integers can have more
-## restrictive validation (ie. must be 5 digits.)
-## 27. Added a ton more doc strings to explain use and derivation requirements
-## and did regularization of the naming conventions.
-## 28. Fixed a range bug in _adjustKey preventing z from being handled properly.
-## 29. Changed behavior of '.' (and shift-.) in numeric controls to move to
-## reformat the value and move the next field as appropriate. (shift-'.',
-## ie. '>' moves to the previous field.
-
-## Version 0.0.6
-## 1. Fixed regex bug that caused autoformat AGE to invalidate any age ending
-## in '0'.
-## 2. New format character 'D' to trigger date type. If the user enters 2 digits in the
-## year position, the control will expand the value to four digits, using numerals below
-## 50 as 21st century (20+nn) and less than 50 as 20th century (19+nn).
-## Also, new optional parameter datestyle = set to one of {MDY|DMY|YDM}
-## 3. revalid parameter renamed validRegex to conform to standard for all validation
-## parameters (see 2 new ones below).
-## 4. New optional init parameter = validRange. Used only for int/dec (numeric) types.
-## Allows the developer to specify a valid low/high range of values.
-## 5. New optional init parameter = validList. Used for character types. Allows developer
-## to send a list of values to the control to be used for specific validation.
-## See the Last Name Only example - it is list restricted to Smith/Jones/Williams.
-## 6. Date type fields now use wxDateTime's parser to validate the date and time.
-## This works MUCH better than my kludgy regex!! Thanks to Robin Dunn for pointing
-## me toward this solution!
-## 7. Date fields now automatically expand 2-digit years when it can. For example,
-## if the user types "03/10/67", then "67" will auto-expand to "1967". If a two-year
-## date is entered it will be expanded in any case when the user tabs out of the
-## field.
-## 8. New class functions: SetValidBackgroundColor, SetInvalidBackgroundColor, SetEmptyBackgroundColor,
-## SetSignedForeColor allow accessto override default class coloring behavior.
-## 9. Documentation updated and improved.
-## 10. Demo - page 2 is now a wxFrame class instead of a wxPyApp class. Works better.
-## Two new options (checkboxes) - test highlight empty and disallow empty.
-## 11. Home and End now work more intuitively, moving to the first and last user-entry
-## value, respectively.
-## 12. New class function: SetRequired(bool). Sets the control's entry required flag
-## (i.e. disallow empty values if True).
-##
-## Version 0.0.5
-## 1. get_plainValue method renamed to GetPlainValue following the wxWidgets
-## StudlyCaps(tm) standard (thanks Paul Moore). ;)
-## 2. New format code 'F' causes the control to auto-fit (auto-size) itself
-## based on the length of the mask template.
-## 3. Class now supports "autoformat" codes. These can be passed to the class
-## on instantiation using the parameter autoformat="code". If the code is in
-## the dictionary, it will self set the mask, formatting, and validation string.
-## I have included a number of samples, but I am hoping that someone out there
-## can help me to define a whole bunch more.
-## 4. I have added a second page to the demo (as well as a second demo class, test2)
-## to showcase how autoformats work. The way they self-format and self-size is,
-## I must say, pretty cool.
-## 5. Comments added and some internal cosmetic revisions re: matching the code
-## standards for class submission.
-## 6. Regex validation is now done in real time - field turns yellow immediately
-## and stays yellow until the entered value is valid
-## 7. Cursor now skips over template characters in a more intuitive way (before the
-## next keypress).
-## 8. Change, Keypress and LostFocus methods added for convenience of subclasses.
-## Developer may use these methods which will be called after EVT_TEXT, EVT_CHAR,
-## and EVT_KILL_FOCUS, respectively.
-## 9. Decimal and numeric handlers have been rewritten and now work more intuitively.
-##
-## Version 0.0.4
-## 1. New .IsEmpty() method returns True if the control's value is equal to the
-## blank template string
-## 2. Control now supports a new init parameter: revalid. Pass a regular expression
-## that the value will have to match when the control loses focus. If invalid,
-## the control's BackgroundColor will turn yellow, and an internal flag is set (see next).
-## 3. Demo now shows revalid functionality. Try entering a partial value, such as a
-## partial social security number.
-## 4. New .IsValid() value returns True if the control is empty, or if the value matches
-## the revalid expression. If not, .IsValid() returns False.
-## 5. Decimal values now collapse to decimal with '.00' on losefocus if the user never
-## presses the decimal point.
-## 6. Cursor now goes to the beginning of the field if the user clicks in an
-## "empty" field intead of leaving the insertion point in the middle of the
-## field.
-## 7. New "N" mask type includes upper and lower chars plus digits. a-zA-Z0-9.
-## 8. New formatcodes init parameter replaces other init params and adds functions.
-## String passed to control on init controls:
-## _ Allow spaces
-## ! Force upper
-## ^ Force lower
-## R Show negative #s in red
-## , Group digits
-## - Signed numerals
-## 0 Numeric fields get leading zeros
-## 9. Ctrl-X in any field clears the current value.
-## 10. Code refactored and made more modular (esp in OnChar method). Should be more
-## easy to read and understand.
-## 11. Demo enhanced.
-## 12. Now has _doc_.
-##
-## Version 0.0.3
-## 1. GetPlainValue() now returns the value without the template characters;
-## so, for example, a social security number (123-33-1212) would return as
-## 123331212; also removes white spaces from numeric/decimal values, so
-## "- 955.32" is returned "-955.32". Press ctrl-S to see the plain value.
-## 2. Press '.' in an integer style masked control and truncate any trailing digits.
-## 3. Code moderately refactored. Internal names improved for clarity. Additional
-## internal documentation.
-## 4. Home and End keys now supported to move cursor to beginning or end of field.
-## 5. Un-signed integers and decimals now supported.
-## 6. Cosmetic improvements to the demo.
-## 7. Class renamed to MaskedTextCtrl.
-## 8. Can now specify include characters that will override the basic
-## controls: for example, includeChars = "@." for email addresses
-## 9. Added mask character 'C' -> allow any upper or lowercase character
-## 10. .SetSignColor(str:color) sets the foreground color for negative values
-## in signed controls (defaults to red)
-## 11. Overview documentation written.
-##
-## Version 0.0.2
-## 1. Tab now works properly when pressed in last position
-## 2. Decimal types now work (e.g. #####.##)
-## 3. Signed decimal or numeric values supported (i.e. negative numbers)
-## 4. Negative decimal or numeric values now can show in red.
-## 5. Can now specify an "exclude list" with the excludeChars parameter.
-## See date/time formatted example - you can only enter A or P in the
-## character mask space (i.e. AM/PM).
-## 6. Backspace now works properly, including clearing data from a selected
-## region but leaving template characters intact. Also delete key.
-## 7. Left/right arrows now work properly.
-## 8. Removed EventManager call from test so demo should work with wxPython 2.3.3
