I have a custom view in which I am trying to implement a popup
contextual menu via Ctrl-Click or Right-Click.
I thought I had to handle all this myself, so I had already refactored
my mouseDown and rightMouseDown events to filter into common methods.
In mouseDown, I detect if the Ctrl button is pressed and invoke my
desired common method. In this common method, I call
popUpContextMenu:withEvent:forView:
I later discovered that if I override menuForEvent:, then the
Ctrl-Click brings up the the contextual menu. But it doesn't handle
the right-click.
So my first question is, does it matter which approach I take to do
this? How bad is it to not implement the menuForEvent: and continue
along my current path? I would rather not undo the code refactoring I
did. I presume that having both menuForEvent: and calling
popUpContextMenu:withEvent:forView: on Ctrl-Click would not be good
because it is redundant.
My second question is, how can I detect if the popup contextual menu
is currently open? The reason I want to know is if the menu is open,
and I decide to left-click outside the menu to cancel, my view may
receive the mouseDown event and does it's normal left-click action. I
would prefer not to perform the action in this case and make it a
no-op.
Thanks,
Eric
