 \wxheading{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.
 
+
+\wxheading{Button states}

+This class supports bitmaps for several different states:

+\twocolwidtha{5cm}
+\begin{twocollist}\itemsep=0pt
+\twocolitem{\windowstyle{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.}
+\twocolitem{\windowstyle{disabled}}{Bitmap shown when the button is disabled.}
+\twocolitem{\windowstyle{selected}}{Bitmap shown when the button is pushed
+(e.g. while the user keeps the mouse button pressed on it)}
+\twocolitem{\windowstyle{focus}}{Bitmap shown when the button has keyboard
+focus but is not pressed.}
+\twocolitem{\windowstyle{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.}
