Laying out Morphs with submorphs outside their bounds

I created a ThoughtBalloonMorph seen here (think of a cartoon if you can't see the image):


It is an invisible morph with three submorphs:
* an EllipseMorph with an embedded TextMorph
* two small CircleMorphs leading from the thinker to the thought.

The problem is that the #bounds of the Morph is 0@0 (for the invisible Morph). Thus, when I add it to a PasteUpMorph with #shrinkWrap resizing, the submorphs are not taken into account and may be cut off, as seen here:


What's the best way to overcome this?

Thanks.

p.s. if you're not viewing this on Nabble, did the images work? (I added them on Nabble.)

Now that I think about it, the question is really: how does one create a morph that is made up of multiple non-overlapping morphs with no background?

Did you ever solve this? I think the way to go is with an invisible container morph, that all of these little bubbles get attached to. Did you try that? What happened?

I didn't solve it yet. I have an invisible parent morph, but I set its size to 0@0. The reason I didn't just have it cover the total area of the composite is that I want mouse actions (e.g. clicks) that are within the area but not actually on one of the bubbles to go through to the background. I guess I could override the event handlers and forward them manually, but I thought someone might know a better way.

Thanks.
