I'm not an expert, but my understanding of the
"WIDGET_DISPLAYCONTEXTMENU" is you should call it from the procedure
handling your events. Since you have the draw widget, you need to add
"/button_events" in your widget_draw, and check if the right button is
clicked in the event handler using "if (event.release EQ 4)" and add
the "WIDGET_DISPLAYCONTEXTMENU" procedure in the if...then statement.
