Hi,
I am creating shape and the subsequent element by prompting the user with a
dialog window (with attributes & references) in the diagram editor. Now I
want to invoke the dialog window to edit properties by double-clicking on a
shape.
I could see from the article "Introducing the GMF runtime", that by
double-clicking connection handles of the shapes, a pop-up window shows up
with related elements, can we override this to achieve the desired behavior.
Could some body help me out how this can be done.
regards,
Phani Kumar K.

Double click on shapes can be handled by using OpenEditPolicy, to add
double click handling to one of your shapes you will need to create an
edit policy that subclass OpenEditPolicy and install it on your shape
edit part like this
installEditPolicy(EditPolicyRoles.OPEN_ROLE, new OpenStateEditPolicy())
then you can return the command you like by overriding the
getOpenCommand method in your edit policy
