@class wxBitmapButton
A bitmap button is a control that contains a bitmap.
It may be placed on a wxDialog or a wxPanel, or indeed almost any other window.
@remarks
A bitmap button can be supplied with a single bitmap, and wxWidgets will draw
all button states using this bitmap. If the application needs more control,
additional bitmaps for the selected state, unpressed focused state, and greyed-out
state may be supplied.
@section wxbitmapbutton_states Button states
This class supports bitmaps for several different states:
@li @b normal: this is the bitmap shown in the default state, it must be always
valid while all the other bitmaps are optional and don't have to be set.
@li @b disabled: bitmap shown when the button is disabled.
@li @b selected: bitmap shown when the button is pushed (e.g. while the user
keeps the mouse button pressed on it)
@li @b focus: bitmap shown when the button has keyboard focus but is not pressed.
@li @b hover: bitmap shown when the mouse is over the button (but it is not pressed).
Notice that if hover bitmap is not specified but the current platform UI uses
hover images for the buttons (such as Windows XP or GTK+), then the focus bitmap
is used for hover state as well. This makes it possible to set focus bitmap only
to get reasonably good behaviour on all platforms.
@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. Has effect only under MS Windows.
@style{wxBU_LEFT}
Left-justifies the bitmap label. Has effect only under MS Windows.
@style{wxBU_TOP}
Aligns the bitmap label to the top of the button.
Has effect only under MS Windows.
@style{wxBU_RIGHT}
Right-justifies the bitmap label. Has effect only under MS Windows.
@style{wxBU_BOTTOM}
Aligns the bitmap label to the bottom of the button.
Has effect only under MS Windows.
@endStyleTable
Note that the wxBU_EXACTFIT style supported by wxButton is not used by this
class as bitmap buttons don't have any minimal standard size by default.
@beginEventTable{wxCommandEvent}
@event{EVT_BUTTON(id, func)}
Process a wxEVT_COMMAND_BUTTON_CLICKED event, when the button is clicked.

Constructor, creating and showing a button.
