- * In the example <xref linkend="composited-window-example"/>, a button is
- * placed inside of an event box inside of a window. The event box is set as
- * composited and therefore is no longer automatically drawn to the screen.
- *
- * When the contents of the event box change, an expose event is generated on
- * its parent window (which, in this case, belongs to the toplevel #GtkWindow).
- * The expose handler for this widget is responsible for merging the changes
- * back on the screen in the way that it wishes.
- *
- * In our case, we merge the contents with a 50% transparency. We also set the
- * background colour of the window to red. The effect is that the background
- * shows through the button.
