Hello,

I have to register a selection listener to change Image for a shape and expand/ collapse has to be done on the event.

Is there any way to register listener for a shape.I want to some operation on specific key pressed.

I have gone through the below post
how can I install EditPolicy to the shape [message #906960]

Can I change the Image on getSelectionInfo method?

Advance thanks for you reply.

Thanks
Raghav

Raghav,

you can influence the way a shape is shown on selection by hooking into the
getSelectionInfoForShape() method. Note that there'a open bugzilla (
https://bugs.eclipse.org/bugs/show_bug.cgi?id=365172) regarding not working
line width settings there.

Registering a listener for selection or reacting on key events is currently
not possible, but there is an open enhancement request for enabling key
shortcuts for features: https://bugs.eclipse.org/bugs/show_bug.cgi?id=323349

Michel,

Thanks for your response.

As of now i am adding listeners to Graphical viewer.

getGraphicalViewer().getControl().addMouseListener(this);

I hope this is a good way as of now.
