Figure toggle not receiving selected/button down events [message #169970]

All,
I'm trying to implement an expand/collapse figure on my figures in
GEF, and am having trouble getting the toggle to see any mouse eens
other than mouseover. The toggle figure is about 2 figures from the root
figure of the edit part. Here is a snippet:

label = new LabelFigure();
label.setText("+");
t = new Toggle(label);
expanded = false;
t.setBorder(BUTTON_BORDER);
t.setRolloverEnabled(true);
t.setRequestFocusEnabled(false);

t.addChangeListener(new ChangeListener() {
public void handleStateChanged(ChangeEvent event) {
if
(event.getPropertyName().equals(ButtonModel.SELECTED_PROPERT Y)) {
if (!expanded) {
expanded = true;
rightCompartment.add(scrollpane);
rightCompartment.revalidate();
label.setText("-");
me.revalidate();
} else {
expanded=false;
label.setText("+");
rightCompartment.remove(scrollpane);
rightCompartment.revalidate();
me.revalidate();
}
}
});

When I click on the figure only the edit policy is receiving any events
for the root figure. Am I missing something?

Thanks!

Pierre

What is LabelFigure? Are you adding any listeners to it? If that is the
case, the events will go to the label and not the toggle.
