I've just moved from RB5 to 200x and am trying to debug some
behaviour under Windows. I have a Canvas with several ContextualMenu
controls, different ones being activated depending on the context
when you right-click. This works fine still on OS/X.
Contextual menus on a Canvas aren't triggering the MouseUp event,
despite returning true from the MouseDown.
From reading other forum posts, it seems that the now approved way
is to use the ConstructContextualMenu event handler.
I can't find any mention in the LanguageReference or ReadMe saying
that MouseDown handling is only for non-contextual clicks but that
seems to be the current Windows behaviour. I'm not sure if that is a
documentation bug or a framework bug.
I also fail to understand how RectControl.ContextualMenuAction works:
"Use this in conjunction with ConstructContextualMenu if you have not
specified the Action event or the Menu Handler for the items on the
contextual menu."
How are you supposed to specify the Action event or the Menu Handler
when using ConstructContextualMenu? ConstructContextualMenu doesn't
allow you to specify a ContextualMenu control - you are passed in a
MenuItem to which you append items.
Is the recommended technique to put a big switch statement inside
your ConstructContextualMenu and ContextualMenuAction event handlers,
rather than having several ContextualMenu controls?
thanks
Andy
