How to make an editpart not selectable ? [message #105325]

Hello,

I am looking for a method to make an editpart not selectable.
I thought that removing the EditPolicy.COMPONENT_ROLE from its
EditPolicies would be enough but it seems that as soon as an EditPart is
contained in a parent that has a EditPolicy.LAYOUT_ROLE installed, the
editpart "child" turns into an object that we can select. Am I right with
my diagnostic?
What I am trying to do is just make the children of a certain EditPart no
selectable, thus all the events in the parent EditPart area would be
treated by the parent and no by the child contained inside. As I said i
tried to remove the COMENT_ROLE from these "children" editpart but it does
not work because the "parent" has got a "LAYOUT_ROLE" installed. Is there
another way to do it ?

Thanks for your help !

Regards,

Arnaud

Hello Arnaud,

have a look at the parent?s editpolicies (espacially the one, that is
assigned to LAYOUT_ROLE):
there could be a method called createChildEditPolicy.
I assume it returns new ResizableEditpolicy
Simply return null here.
Hope it fulfills your desired purposes!

Regards, Ingo

When you editpart is grouped, have it return false from
EditPart.isSelectable.
