No, not at all. You don't need a mouseClicked method, or any method
handing MouseEvents directly. All mouse events are (should be) handled
by the StandardMouseModeInterpreter embedded in the layer. That thing
is making the calls to the OMGraphicHandlerLayer's
GestureResponsePolicy methods. In effect, the
StandardMouseModeInterpreter is asking the layer how it should handle
the different situations it is encountering. The Interpreter figures
out that a right-click occurs on an OMGraphic, and makes the call to
the layer's getItemsForOMGraphicMenu letting you know which OMGraphic
was right-clicked on, asking you what you want to do. If you return
null, it does nothing. If you return a list of MenuItems, it displays
them.
