Yes. This is how we designed the right click handling for gtk2. If we 
allow the default action to happen then you can suddenly see 2 popup 
menus: one your and one standard - for example for TEdit or TPageConrol 
(since gtk2 will handle the right click and will show a popup on it and 
LCL will do the same).

PopupMenu.PopupAt();
