Gets a reference to the BeforeRightClick event
CXlBeforeRightClickEvent& BeforeRightClickEvent( );
The function returns a reference to the application's BeforeRightClick event, which is of type CXlBeforeRightClickEvent.
The BeforeRightClick event is raised when the user right-clicks in a worksheet. All registered observers receive the event via the CXlEventObserver::Update method.
When observers are notified, an argument of type CXlCancellableRangeEventArgs is passed. Observers can cancel normal processing of the right-click by cancelling the event using CXlCancellableRangeEventArgs::SetCancel(false).
Observers can register for this event at any point in the life of the XLL. Registration can be done explicitly using Register, or automatically by creating an instance of CXlBeforeRightClickEventStaticObserver.
