    - #### addShowContextMenuHandler

          com.google.gwt.event.shared.HandlerRegistration addShowContextMenuHandler(ShowContextMenuHandler handler)

      Executed when the right mouse button is clicked. The default implementation of this method auto-creates a `Menu` from the `contextMenu` property on this component and then calls `Menu.showContextMenu()` on it to show it.

      If you want to show a standard context menu, you can simply define your Menu and set it as the contextMenu property on your component - you do not need to override this method.

      If you want to do some other processing before showing a menu or do something else entirely, then you should override this method. Note that the return value from this method controls whether or not the native browser context menu is shown.

      Parameters:
        `handler` - the showContextMenu handler
      Returns:
        `HandlerRegistration` used to remove this handler
