Hi All,

I have use GEF with EMF in order to make a small example. I have
intalled a XYLayoutEditPolicy on the root node and overriden the
createChangeConstraintCommand() method to allow resizing and moving
parts but I can't even select my parts once they are created.

Any Idea ?

Regards.

Maybe you just need to install a selection feedback edit policy? That
is, in your edit part,

installEditPolicy(
EditPolicy.SELECTION_FEEDBACK_ROLE, new SelectionEditPolicy());

Or something along those lines.

It doesn't help. Actually, just installing a XY layout edit policy and
overriding the createChangeConstraintCommand() method should be enough.
The parent owns a freeform layer. I still wonder what I might have
forgotten. I checked several times the code and I am not able to see
what's wrong.

Hello,
I was wondering because I had a similar problem, too.

My Background Figure is a FreeformLayer with a FreeformLayout.
I can create Figure one on that background-figure.
I can select, resize and move figure one.
I can create Figure two !within! Figure one.
But I can not select Figure two.
I can move it but without any feedback of selection or moving and the coordinates seems to be relative the upper left corner of figure one, not relative to the background figurs corner.

It's pretty interesting because I did the most akin to a GEF-Tutorial.

It now works fine because I use ResizableEditPolicy and LayoutEditPolicy instead of the XYLayoutEditPolicy.

But it would be nice conceive the problem because in the tutorial it seems to work fine...

Best regards & thanks in advance
Alex
