    @class wxBitmapButton
    @wxheader{bmpbuttn.h}

    A bitmap button is a control that contains a bitmap.
    It may be placed on a @ref overview_wxdialog "dialog box" or panel, or indeed
    almost any other window.

    @beginStyleTable
    @style{wxBU_AUTODRAW}:
           If this is specified, the button will be drawn automatically using
           the label bitmap only, providing a 3D-look border. If this style is
           not specified, the button will be drawn without borders and using
           all provided bitmaps. WIN32 only.
    @style{wxBU_LEFT}:
           Left-justifies the bitmap label. WIN32 only.
    @style{wxBU_TOP}:
           Aligns the bitmap label to the top of the button. WIN32 only.
    @style{wxBU_RIGHT}:
           Right-justifies the bitmap label. WIN32 only.
    @style{wxBU_BOTTOM}:
           Aligns the bitmap label to the bottom of the button. WIN32 only.
    @endStyleTable

    @beginEventTable
    @event{EVT_BUTTON(id\, func)}:
           Process a wxEVT_COMMAND_BUTTON_CLICKED event, when the button is
           clicked.

        Constructor, creating and showing a button.
        
        @param parent
        Parent window. Must not be @NULL.
        
        @param id
        Button identifier. The value wxID_ANY indicates a default value.
        
        @param bitmap
        Bitmap to be displayed.
        
        @param pos
        Button position.
        
        @param size
        Button size. If wxDefaultSize is specified then the button is sized
        appropriately for the bitmap.
        
        @param style
        Window style. See wxBitmapButton.
        
        @param validator
        Window validator.

        Window name.

                   provide, and wxWidgets will draw the button correctly
                   in its different states. If you want more control,
