+/**
+@short Convenience class to mangage context menus
+@author Matthias Ettrich <ettrich@kde.org>
+
+KContextMenuManager manages configurable context popup menus. Instead
+of reimplementing QWidget::mousePressEvent() or
+ QWidget::mouseReleaseEvent() and/or QWidget::keyPressEvent(), simply
+create the popup menu and insert it into the context menu manager with
+the static function insert().
+
+Example:
+\code
+ KContextMenuManager::insert( myWidget, myPopupMenu );
+\endcode
+
+
+Context menus are invoked with either a special shortcut key (usually
+the menu key) or the right mouse button.
+
+Menus are configurable in the [ContextMenus] group of the application's
+configuration file, usually in kdeglobals:
+\code
+ [ContextMenus]
+ ShowOnPress=true|false
+\endcode
+
+@p ShowOnPress defines whether the menu shall be shown on mouse
+press or on mouse release.
+
+The shortcut key to invoke the context menu is defined in the standard
+[Keys] section of the application configuration:
+\code
+ [Keys]
+ ...
+ PopupContextMenu=Menu
+ ...
+\endcode
+The key can be configured with the standard keys module in the KDE control center.
+
+If the popup menu is invoked with the keyboard shortcut, it's shown at
+the position of the micro focus hint of the widget ( QWidget::microFocusHint() ).
