Hi Guys,
I have a model that can be rendered in both a collapsed and an
un-collapsed state. In a collapsed state, the model looks like a single
node (similar to the Or Gate in the logic example). When un-collapsed, it
looks like a border with other nodes contained within it (similar to the
Circuit Node in the logic example). Does anyone know how to do this?
Please note that it may be a better idea to create a new edit part for
each, as the two nodes behave differently....but if I simply try to
refresh, gef will recognize that the specified model already has an edit
part and not bother to create a new one.
thanks in advance,
-Rouben Meschian

Did something like this a couple of weeks ago.
1) Attatch mouse listener to the figure that represents the +/-
....
private MouseListener mouseListener = new MouseListener() {
public void mousePressed(MouseEvent me) {
handleActionPerformed(me);
}
....
2) Based on the action of that figured, create convenience methods to
show/hide content. This requires a wrapper figure that holds the
contents. The contents consist of a root compartment that holds other
compartments. When you hide, remove the root compartment, when you show
toss it back in. make sure to revalidate() when doing so.
It would be fantastic if we had a repository of reusable editparts, like
a GEF Corner (similar to EMF corner).
I feel like people are recreating functionality everywhere.
Cheers,
~ Chris
