   \class MenuButton menubutton.h
   \brief The MenuButton class is a pushbutton with a menu.
 
-  Similar in function to a QComboBox.
+  When the user presses the menubutton's pushbutton, the menu pops up.
+  A menu is composed of menu items each of which has a string label,
+  and optionally an icon.
+
+  The index of the item that the user's input device (e.g. stylus) is
+  pointing at is the currentItem(), whose text is available using
+  currentText().
+
+  Menu items are inserted with the \link MenuButton::MenuButton()
+  constructor\endlink, insertItem() or insertItems(). Separators are
+  inserted with insertSeparator(). All the items in the menu can be
+  removed by calling clear().
+
+  Items can be selected programmatically using select(). When a menu
+  item is selected (programmatically or by the user), the selected()
+  signal is emitted.
