Hi,

I'm having trouble defining my own border. I'm trying to do something
like a UML "multi-object" (see attached pic). This works so far, but
only if I use the setClip method as shown in the attached class (I've
learned that from some example code). But this seems to be causing
trouble with repainting in some situations...

In fact, I've seen a message where somebody suggests not to use
setClip() - returning appropriate Insets shall be the solution.
Unfortunately, I can't find the message in this newsgroup any more.

So I tried to return Insets as can be seen in the code, but my border
wouldn't appear, so I switched back to the setClip() solution for now.

Can anybody help me figuring out what I'm doing wrong?

Thanks in advance,
Chris

I had a similar problem, and I ended up just writing my own Figure for it. That
is a lot easier than trying to create a border. I can probably send you the code
for it, if you like.

Hi Del,

that would be awesome. The only problem is that I need to add/remove
that border depending on a boolean attribute of the semantic element -
with your solution, I would have to learn how to exchange the figure of
an EditPart :-)

In fact, I thought it's pretty easy to write a custom border, but this
doesn't seem to be the case - does anybody have a solution to the
original problem?

Thanks,
Chris
