+
+    Since version 2.9.1 wxButton supports showing both text and an image
+    (currently only when using wxMSW, wxGTK or wxOSX/Cocoa ports), see
+    SetBitmap() and SetBitmapLabel(), SetBitmapDisabled() &c methods. In the
+    previous wxWidgets versions this functionality was only available in (the
+    now trivial) wxBitmapButton class which was only capable of showing an
+    image without text.
+
+    A button may have either a single image for all states or different images
+    for the following states (different images are not currently supported
+    under OS X where the normal image is used for all states):
+    @li @b normal: the default state
+    @li @b disabled: bitmap shown when the button is disabled.
+    @li @b pressed: 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 as in this case the button is in the pressed state)
+    @li @b current: bitmap shown when the mouse is over the button (but it is
+        not pressed although it may have focus). Notice that if current 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.
+
+    All of the bitmaps must be of the same size and the normal bitmap must be
+    set first (to a valid bitmap), before setting any other ones. Also, if the
+    size of the bitmaps is changed later, you need to change the size of the
+    normal bitmap before setting any other bitmaps with the new size (and you
+    do need to reset all of them as their original values can be lost when the
+    normal bitmap size changes).
+
+    The position of the image inside the button be configured using
+    SetBitmapPosition(). By default the image is on the left of the text.
+
+    Please also notice that GTK+ uses a global setting called @c
+    gtk-button-images to determine if the images should be shown in the buttons
+    at all. If it is off (which is the case in e.g. Gnome 2.28 by default), no
+    images will be shown, consistently with the native behaviour.
