+
+masked.TextCtrl:
is a sublassed text control that can carefully control the user's input
based on a mask string you provide.
- General usage example:
+ General usage example::
+
control = masked.TextCtrl( 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>masked.ComboBox</b>
+masked.ComboBox:
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>masked.Ctrl</b>
+masked.Ctrl:
is actually a factory function for several types of masked edit controls:
- <b>masked.TextCtrl</b> - standard masked edit text box
- <b>masked.ComboBox</b> - adds combobox capabilities
- <b>masked.IpAddrCtrl</b> - adds special semantics for IP address entry
- <b>masked.TimeCtrl</b> - special subclass handling lots of types as values
- <b>masked.NumCtrl</b> - special subclass handling numeric values

-<b>INITILIZATION PARAMETERS
-========================

-Allowed mask characters and function:
+Initialization Parameters
+-------------------------
+mask
+ 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

+ C Allow any letter, upper or lower
+ X Allow string.letters, string.punctuation, string.digits
+ & Allow string.punctuation only
+ \* Allow any ansi character
+ ========= ==========================================================
These controls define these sets of characters using string.letters,
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:
+ your application's initialization code::
import locale
locale.setlocale(locale.LC_ALL, '')
+ The controls now also support (by popular demand) all "ansi" chars,
+ that is, all ascii codes between 32 and 255, by use of the * mask character.
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
(use \\ for literal backslash, as in: r'CCC\\NNN'.)
- <b>Note:</b>
+ *Note:*
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
forth (see below). These allow you to construct reasonable
numeric entry controls.
- <b>Note:</b>
+ *Note:*
Changing the mask for a control deletes any previous field classes
(and any associated validation or formatting constraints) for them.
-<b>useFixedWidthFont=</b>
+useFixedWidthFont
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

+defaultEncoding
+ (Applies to unicode systems only) By default, the default unicode encoding
+ used is latin1, or iso-8859-1. If necessary, you can set this control-level
+ parameter to govern the codec used to decode your keyboard inputs.
+ (This is a control-level parameter.)
-<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:

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
This value must satisfy the non-editable characters of the mask,
but need not conform to the replaceable characters.
-<b>groupChar=
-decimalChar=</b>
+groupChar
+
+decimalChar
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>
+ Eg::
+
+ formatcodes = ',', groupChar='\'' allows 12'345.34
+ formatcodes = ',', groupChar='.', decimalChar=',' allows 12.345,34
+
+ (These are control-level parameters.)
+
+shiftDecimalChar
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.
+ (This is a control-level parameter.)
-<b>useParensForNegatives=False</b>
+useParensForNegatives=False
This option can be used with signed numeric format controls to
indicate signs via () rather than '-'.
+ (This is a control-level parameter.)
-<b>autoSelect=False</b>
+autoSelect=False
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>
+autoCompleteKeycodes=[]
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
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 masked.ComboBox, 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.

+ ===================== ==================================================================
+
+
+Coloring Behavior
+=================
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

+
+Fields
+======
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>
+fields
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.
Any field not represented by the list or dictionary will be
implicitly created by the control.
- eg:
+ Eg::
+
fields = [ Field(formatcodes='_r'), Field('choices=['a', 'b', 'c']) ]
- or
+
+ Or::
+
fields = {
- 1: ( Field(formatcodes='_R', choices=['a', 'b', 'c']),
- 3: ( Field(choices=['01', '02', '03'], choiceRequired=True)
+ 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
+ ============== =============================================================================
+ fillChar if set for a field, it will override the control's fillChar for that field

+ 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.

-<b>Control Class Functions:
-========================
- .GetPlainValue(value=None)</b>
+Control Class Functions
+=======================
+.GetPlainValue(value=None)
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>
+.ClearValue()
Returns the control's value to its default, and places the
cursor at the beginning of the control.
- <b>.SetValue()</b>
+.SetValue()
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,
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:
+
+ Eg::
+
mask = '(###) ###-####'
.SetValue('1234567890') => '(123) 456-7890'
.SetValue('(123)4567890') => '(123) 456-7890'
.SetValue('%.2f' % -111.12345 ) => ' -111.12'
- <b>.IsValid(value=None)</b>
+.IsValid(value=None)
Returns True if the value specified (or the value of the control
if not specified) passes validation tests
- <b>.IsEmpty(value=None)</b>
+.IsEmpty(value=None)
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>
+.IsDefault(value=None)
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>
+.Refresh()
Recolors the control as appropriate to its current settings.
- <b>.SetCtrlParameters(**kwargs)</b>
+.SetCtrlParameters(\*\*kwargs)
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:
+
+ Eg::
+
ctl = masked.TextCtrl( self, -1 )
ctl.SetCtrlParameters( mask='###-####',
defaultValue='555-1212',
formatcodes='F')
- <b>.GetCtrlParameter(parametername)</b>
+.GetCtrlParameter(parametername)
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
+ *Note:* Each of the control parameters can also be set using its
own Set and Get function. These functions follow a regular form:

- <b>.SetFieldParameters(field_index, **kwargs)</b>
+.SetFieldParameters(field_index, \*\*kwargs)
This function allows you to specify change individual field
parameters after construction. (Indices are 0-based.)

##
## Current Issues:
## ===================================
## CHANGELOG:
## ====================
+## Version 1.9
+## 1. Now ignores kill focus events when being destroyed.
+## 2. Added missing call to set insertion point on changing fields.
+## 3. Modified SetKeyHandler() to accept None as means of removing one.
+## 4. Fixed keyhandler processing for group and decimal character changes.
+## 5. Fixed a problem that prevented input into the integer digit of a
+## integerwidth=1 numctrl, if the current value was 0.
+## 6. Fixed logic involving processing of "_signOk" flag, to remove default
+## sign key handlers if false, so that SetAllowNegative(False) in the
+## NumCtrl works properly.
+## 7. Fixed selection logic for numeric controls so that if selectOnFieldEntry
+## is true, and the integer portion of an integer format control is selected
+## and the sign position is selected, the sign keys will always result in a
+## negative value, rather than toggling the previous sign.
+##
+##
+## Version 1.8
+## 1. Fixed bug involving incorrect variable name, causing combobox autocomplete to fail.
+## 2. Added proper support for unicode version of wxPython
+## 3. Added * as mask char meaning "all ansi chars" (ordinals 32-255).
+## 4. Converted doc strings to use reST format, for ePyDoc documentation.
+## 5. Renamed helper functions, classes, etc. not intended to be visible in public
+## interface to code.
+##
## Version 1.7
## 1. Fixed intra-right-insert-field erase, such that it doesn't leave a hole, but instead
## shifts the text to the left accordingly.
