@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.
+ 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.
