Hello Guys,
Can someone please give me a brief idea how to go about this?
I want a pop-up when a connection is made from one component to another
component in my gmf diagram.
Any help will be much appreciated.
Thanks,
julan

Hi Julan,
I'm not sure how favourable this method is, but you could do this with
custom commands and edit policies.
I needed a connection that would do more than just connecting elements,
so I created a new subclass of CreateConnectionRequest detailing the
behaviour I wanted. Next I created an EditPolicy extending
GraphicalNodeEditPolicy and overrode the #getCommand(Request) method to
handle my new request type. I then installed the EditPolicy on my shape
of choice in the GRAPHICAL_NODE_ROLE.
Where your popup comes in is that #getCommand(Request) method in your
new EditPolicy. Simply create a new subclass of command whose #execute()
method throws up a dialog and does whatever you want with the results
and then return that as the result of the #getCommand(Request) call. Or,
if you want more than just that, chain it in a CompoundCommand for
similar effects.
I know I've been quite abstract, but I hope it helps.
Good luck,
Will
