Add decoration to EditPart? [message #229837]

Is it possible to add a decoration to an EditPart?

I would simply like to place a label next to an EditPart without the
label being a part of the EditPart. Meaning when you select the EditPart
the associated label should not be selected.

You can use transparent border as per the attached newsgroup msg.

If you want a label that is always at the same location wrt the figure,
then you have to create your own figure with some transparent border to
put the label (to create the illusion that the label is outside the
figure). Look into getHandleBounds() of interface HandleBounds.

If you want a label that can be moved anywhere on the screen (like in
the case of a label of a port for a component) then you may want to
create another layer for your labels and create a label locator class
(extends AbstractLocator). The parent-child figure relationship will
obviously not like usual but since the label should be the leaf of the
relationship tree, you can probably create a simple (like getOwner()???)
just so that you can get to the figure from the label (to replace
getParent()).

The HandleBounds interface is exactly what I was looking for, thank you
very much.

Now I simply use a Label with an icon and let getHandleBounds() return
the value of getIconBounds()..

Hi Dave!

I wanted to do exactly the same thing...
I tried the solution proposed by Nhu but the part of the figure that is
outside the handle bounds is still selectable this way, which is not
what we wanted... or am I missing something?

Thanks for your help!
Regards,

Arnaud
