phoenix_title wx.lib.masked.textctrl.BaseMaskedTextCtrl

This is the primary derivation from MaskedEditMixin. It provides a general masked text control that can be configured with different masks.

However, this is done with an extra level of inheritance, so that “general” classes like masked.TextCtrl can have all possible attributes, while derived classes, like masked.TimeCtrl and masked.NumCtrl can prevent exposure of those optional attributes of their base class that do not make sense for their derivation. Therefore, we define:

BaseMaskedTextCtrl(TextCtrl, MaskedEditMixin)

and:

masked.TextCtrl(BaseMaskedTextCtrl, MaskedEditAccessorsMixin).

This allows us to then derive:

masked.NumCtrl( BaseMaskedTextCtrl )

and not have to expose all the same accessor functions for the derived control when they don’t all make sense for it.

In practice, BaseMaskedTextCtrl should never be instantiated directly, but should only be used in derived classes.

class BaseMaskedTextCtrl(wx.TextCtrl, MaskedEditMixin)

This is the primary derivation from MaskedEditMixin. It provides a general masked text control that can be configured with different masks.

However, this is done with an extra level of inheritance, so that “general” classes like masked.TextCtrl can have all possible attributes, while derived classes, like masked.TimeCtrl and masked.NumCtrl can prevent exposure of those optional attributes of their base class that do not make sense for their derivation. Therefore, we define:

BaseMaskedTextCtrl(TextCtrl, MaskedEditMixin)

and:

masked.TextCtrl(BaseMaskedTextCtrl, MaskedEditAccessorsMixin).

This allows us to then derive:

masked.NumCtrl( BaseMaskedTextCtrl )

and not have to expose all the same accessor functions for the derived control when they don’t all make sense for it.

In practice, BaseMaskedTextCtrl should never be instantiated directly, but should only be used in derived classes.


Methods

__init__(self, parent, id=-1, value = '', pos = wx.DefaultPosition, size = wx.DefaultSize, style = wx.TE_PROCESS_TAB, validator=wx.DefaultValidator, name = 'maskedTextCtrl', setupEventHandling = True, **kwargs)

Default class constructor.

Parameters

  • parent (wx.Window) – the window parent. Must not be None;

  • id (integer) – window identifier. A value of -1 indicates a default value;

  • value (string) – value to be shown;

  • pos (tuple or wx.Point) – the control position. A value of (-1, -1) indicates a default position, chosen by either the windowing system or wxPython, depending on platform;

  • size – the control size. A value of (-1, -1) indicates a default size, chosen by either the windowing system or wxPython, depending on platform;

  • style (integer) – the window style;

  • validator (wx.Validator) – this is mainly provided for data-transfer, as control does its own validation;

  • name (string) – the window name;

  • setupEventHandling (boolean) – setup event handling by default.


ChangeValue(self, value)

Provided to accommodate similar functionality added to base control in wxPython 2.7.1.1.

Parameters

value (string) – new value for control, this will not fire an event


Clear(self)

Blanks the current control value by replacing it with the default value.


Cut(self)

This function redefines the externally accessible TextCtrl.Cut to be a smart “erase” of the text in question, so as not to corrupt the masked control.

Note

This must be done in the class derived from the base wx control.


IsEmpty(*args, **kw)

IsEmpty() -> bool

Returns true if the control is currently empty.


IsModified(self)

This function overrides the raw TextCtrl.IsModified method, because the masked edit mixin uses SetValue to change the value, which doesn’t modify the state of this attribute. So, the derived control keeps track on each keystroke to see if the value changes, and if so, it’s been modified.


ModifyValue(self, value, use_change_value=False)

This factored function of common code does the bulk of the work for SetValue and ChangeValue.

Parameters

  • value (string) – new value for control

  • use_change_value (boolean) – if True uses ChangeValue


Paste(self)

This function redefines the externally accessible TextCtrl.Paste to be a smart “paste” of the text in question, so as not to corrupt the masked control.

Note

This must be done in the class derived from the base wx control.


Refresh(self)

This function redefines the externally accessible TextCtrl.Refresh to validate the contents of the masked control as it refreshes.

Note

This must be done in the class derived from the base wx control.


SetFont(self, *args, **kwargs)

Set the font, then recalculate control size, if appropriate.

see TextCtrl.SetFont for valid arguments


SetValue(self, value)

This function redefines the externally accessible TextCtrl.SetValue to be a smart “paste” of the text in question, so as not to corrupt the masked control.

Note

This must be done in the class derived from the base wx control.


Undo(self)

This function defines the undo operation for the control. (The default undo is 1-deep.)
