.. _wx.adv.BitmapComboBox:

==========================================================================================================================================
|phoenix_title|  **wx.adv.BitmapComboBox**
==========================================================================================================================================

A combobox that displays bitmap in front of the list items.          

It currently only allows using bitmaps of one size, and resizes itself so that a bitmap can be shown next to the text field. 





.. _BitmapComboBox-styles:

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

This class supports the following styles: 

  

- ``wx.CB_READONLY``: Creates a combobox without a text editor. On some platforms the control may appear very different when this style is used.  
- ``wx.CB_SORT``: Sorts the entries in the list alphabetically.  
- ``wx.TE_PROCESS_ENTER``: The control will generate the event wxEVT_TEXT_ENTER (otherwise pressing Enter key is either processed internally by the control or used for navigation between dialog controls). Windows only.  










.. _BitmapComboBox-events:

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

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


- EVT_COMBOBOX: Process a  ``wxEVT_COMBOBOX``   event, when an item on the list is selected.   
- EVT_TEXT: Process a  ``wxEVT_TEXT``   event, when the combobox text changes.   
- EVT_TEXT_ENTER: Process a  ``wxEVT_TEXT_ENTER``   event, when ``RETURN`` is pressed in the combobox.   








         



.. note:: 

   While :ref:`wx.adv.BitmapComboBox`  contains the :ref:`wx.ComboBox`  API, but it might not actually be derived from that class. In fact, if the platform does not have a native implementation, :ref:`wx.adv.BitmapComboBox`  will inherit from :ref:`wx.adv.OwnerDrawnComboBox`. You can determine if the implementation is generic by checking whether  ``GENERIC_BITMAPCOMBOBOX``   is defined. Currently  :ref:`wx.adv.BitmapComboBox`  is implemented natively for MSW and GTK+.  







.. seealso:: :ref:`wx.ComboBox`, :ref:`wx.Choice`, :ref:`wx.adv.OwnerDrawnComboBox`, :ref:`wx.CommandEvent`    







.. todo:: create ``CB_PROCESS_ENTER`` rather than reusing ``wx.TE_PROCESS_ENTER``!
