Any component that can be placed into a menu should implement this interface.
This interface is used by MenuSelectionManager
to handle selection and navigation in menu hierarchies.
Processes a mouse event. event is a MouseEvent with
source being the receiving element's component. path is the
path of the receiving element in the menu hierarchy including the
receiving element itself. manager is the
MenuSelectionManagerfor the menu hierarchy. This method should
process the MouseEvent and change the menu selection if necessary
by using MenuSelectionManager's API Note: you do not have to
forward the event to sub-components. This is done automatically by the
MenuSelectionManager.
Parameters:
event - a MouseEvent to be processed
path - the path of the receiving element in the menu hierarchy
manager - the MenuSelectionManager for the menu hierarchy
path - the path of the receiving element in the menu hierarchy
manager - the MenuSelectionManager for the menu hierarchy
menuSelectionChanged
void menuSelectionChanged(boolean isIncluded)
Call by the MenuSelectionManager when the MenuElement is
added or removed from the menu selection.
Parameters:
isIncluded - can be used to indicate if this MenuElement is
active (if it is a menu) or is on the part of the menu path that
changed (if it is a menu item).
This method should return the java.awt.Component used to paint the
receiving element. The returned component will be used to convert events
and detect if an event is inside a MenuElement's component.
