==========================================================================================================================================

A bitmap button is a control that contains a bitmap.          

Notice that since wxWidgets 2.9.1 bitmap display is supported by the base :ref:`Button`  class itself and the only tiny advantage of using this class is that it allows to specify the bitmap in its constructor, unlike :ref:`Button`. Please see the base class documentation for more information about images support in :ref:`Button`. 





.. _BitmapButton-styles:

|styles| Window Styles
================================

This class supports the following styles: 

- ``BU_LEFT``: Left-justifies the bitmap label.  
- ``BU_TOP``: Aligns the bitmap label to the top of the button.  
- ``BU_RIGHT``: Right-justifies the bitmap label.  
- ``BU_BOTTOM``: Aligns the bitmap label to the bottom of the button.  

Note that the ``BU_EXACTFIT`` style supported by
:ref:`Button`  is not used by this class as bitmap buttons don't have any minimal standard size by default. 





.. _BitmapButton-events:

|events| Events Emitted by this Class
=====================================

Handlers bound for the following event types will receive a :ref:`CommandEvent` parameter.

- EVT_BUTTON: Process a  ``wxEVT_COMMAND_BUTTON_CLICKED``   event, when the button is clicked.

.. class:: BitmapButton(Button)

   A bitmap button is a control that contains a bitmap.
   
   **Possible constructors**::

       BitmapButton()
       
       BitmapButton(parent, id=ID_ANY, bitmap=NullBitmap, pos=DefaultPosition,
                    size=DefaultSize, style=BU_AUTODRAW, validator=DefaultValidator,
                    name=ButtonNameStr)
       



   .. method:: __init__(self, *args, **kw)



      |overload| **Overloaded Implementations**:

      **~~~**

      
      **__init__** `(self)`
      
      Default constructor.                   
      
      
      
      
      **~~~**

      
      **__init__** `(self, parent, id=ID_ANY, bitmap=NullBitmap, pos=DefaultPosition, size=DefaultSize, style=BU_AUTODRAW, validator=DefaultValidator, name=ButtonNameStr)`
      
      Constructor, creating and showing a button.                  
      
      
      
      
      :param `parent`: Parent window. Must not be ``None``.   
      :type `parent`: Window
      :param `id`: Button identifier. The value ``ID_ANY`` indicates a default value.   
      :type `id`: int
      :param `bitmap`: Bitmap to be displayed.   
      :type `bitmap`: Bitmap
      :param `pos`: Button position. If ``DefaultPosition``   is specified then a default position is chosen.   
      :type `pos`: Point
      :param `size`: Button size. If ``DefaultSize``   is specified then the button is sized appropriately for the bitmap.   
      :type `size`: Size
      :param `style`: Window style. See :ref:`BitmapButton`.   
      :type `style`: long
      :param `validator`: Window validator.   
      :type `validator`: Validator
      :param `name`: Window name.  
      :type `name`: string
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
                        
      
      
      
      .. note:: 
      
         The bitmap parameter is normally the only bitmap you need to provide, and wxWidgets will draw the button correctly in its different states. If you want more control, call any of the functions :meth:`SetBitmapPressed` , :meth:`SetBitmapFocus` , :meth:`SetBitmapDisabled` .
