Bug 112234

David, I have seen this too.. Any idea what this is caused by.  I am using the VMDNodeWidget.

I do not know the root cause but it looks like that VMDNodeWidget header has wrongly resolved layout. If you would call:
"myVMDNodeWidget.getHeader ().setCheckClipping (true);" then the "-" icon would disappear.

This requires futher investigation. Mainly it is about locations, boundaries, layout and constrain of each widget within
the VMDNodeWidget.

The easiest solution would be to reproduce it with test.vmd.VMDTest example. Joelle, could you modify the example to
reproduce this issue? Thanks.

I change VMDColorScheme in my VMDGraphScene to "NetBeans60Scheme" and I put some nodes in my scene, one of the nodes has
a pin with a large text. When I press the button (+), the node is contracted, but the icon (+) stays in the same place.

This issue is caused by the problem in justify-aware layout.

The header is not reflecting a new value of the node widget since the widget is still the same - only size of inner pin
widget is changing.

Temporary workaround is to apply following patch:

         Rectangle rectangle = minimized ? new Rectangle () : null;
         for (Widget widget : getChildren ())
             if (widget != header  &&  widget != pinsSeparator) {
-                getScene ().getSceneAnimator ().animatePreferredBounds (widget,
 minimized  && isMinimizableWidget (widget) ? rectangle : null);
+                SceneAnimator sceneAnimator = getScene ().getSceneAnimator ();
+                sceneAnimator.animatePreferredBounds (widget, minimized  && isM
inimizableWidget (widget) ? rectangle : null);
+                final Animator animator = sceneAnimator.getPreferredBoundsAnima
tor ();
+                animator.addAnimatorListener(new AnimatorListener () {
+                    public void animatorStarted(AnimatorEvent event) {
+                    }
+
+                    public void animatorReset(AnimatorEvent event) {
+                    }
+
+                    public void animatorFinished(AnimatorEvent event) {
+                        animator.removeAnimatorListener (this);
+                    }
+
+                    public void animatorPreTick(AnimatorEvent event) {
+                    }
+
+                    public void animatorPostTick(AnimatorEvent event) {
+                        header.revalidate();
+                    }
+                });
             }
         minimizeWidget.setImage (scheme.getMinimizeWidgetImage (this));
     }

Still leaving the issue as unresolved until proper fix is introduced.
