==========================================================================================================================================
|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.

   .. method:: __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.
      
      :param wx.Window `parent`: the window parent. Must not be ``None``;
      :param integer `id`: window identifier. A value of -1 indicates a default value;
      :param string `value`: value to be shown;
      :param `pos`: the control position. A value of (-1, -1) indicates a default position,
       chosen by either the windowing system or wxPython, depending on platform;
      :type `pos`: tuple or :class:`wx.Point`
      :param `size`: the control size. A value of (-1, -1) indicates a default size,
       chosen by either the windowing system or wxPython, depending on platform;
      :param integer `style`: the window style;
      :param wx.Validator `validator`: this is mainly provided for data-transfer, as control does
        its own validation;
      :param string `name`: the window name;
      :param boolean `setupEventHandling`: setup event handling by default.


   .. method:: ChangeValue(self, value)

      Provided to accommodate similar functionality added to base
      control in wxPython 2.7.1.1.
      
      :param string `value`: new value for control, this will not fire an event


   .. method:: Clear(self)

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


   .. method:: Cut(self)

      This function redefines the externally accessible :meth:`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.


   .. method:: IsEmpty(\*args, \*\*kw)

      IsEmpty() -> bool
      
      Returns true if the control is currently empty.


   .. method:: IsModified(self)

      This function overrides the raw :meth:`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.


   .. method:: ModifyValue(self, value, use_change_value=False)

      This factored function of common code does the bulk of the work for
      SetValue and ChangeValue.
      
      :param string `value`: new value for control
      :param boolean `use_change_value`: if ``True`` uses :meth:`~lib.masked.textctrl.TextCtrl.ChangeValue`


   .. method:: Paste(self)

      This function redefines the externally accessible :meth:`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.


   .. method:: Refresh(self)

      This function redefines the externally accessible :meth:`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.


   .. method:: SetFont(self, \*args, \*\*kwargs)

      Set the font, then recalculate control size, if appropriate.
      
      see :meth:`TextCtrl.SetFont` for valid arguments


   .. method:: SetValue(self, value)

      This function redefines the externally accessible :meth:`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.


   .. method:: Undo(self)

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