/**
|
|
@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() ).
