[news.eclipse.tools.gef] Palette should initially be expanded

[Matt Dickie <m.dickie@xxxxxxxxxx>]

Hi all,

The palette of my graphical editor is initially hidden. I would like it 
to initially be expanded. I have having difficulty figuring out how to 
do this. I have changed the createPalettePreferences method for my 
editor so that it sets the initaly state to STATE_EXPANDED, as below:

    FlyoutPreferences prefs = 
FlyoutPaletteComposite.createFlyoutPreferences(
        GFEUIPlugin.getDefault().getPluginPreferences());
    prefs.setPaletteState(1);
    return prefs;

The palette is briefly expanded, but then collapses. It seems this piece 
of code is to blame (in FlyoutPaletteComposite):

public void setGraphicalControl(Control graphicalViewer) {
    Assert.isTrue(graphicalViewer != null);
    Assert.isTrue(graphicalViewer.getParent() == this);
    Assert.isTrue(graphicalControl == null);
    graphicalControl = graphicalViewer;
    addListenerToCtrlHierarchy(graphicalControl, SWT.MouseEnter, new 
Listener() {
    public void handleEvent(Event event) {
      if (!isInState(STATE_EXPANDED))
        return;
      Display.getCurrent().timerExec(250, new Runnable() {
        public void run() {
          if (isDescendantOf(graphicalControl,
               Display.getCurrent().getCursorControl())
                    && isInState(STATE_EXPANDED))
            setState(STATE_COLLAPSED);
          }
      });
    }
  });
}

I don't understand what this code is trying to achieve besides 
collapsing my palette when I don't want it collapsed. I would like to 
override this method and not call addListenerToCtrlHierarchy, but 
unfortunately I can't because graphicalControl is a private field so I 
can't set it.

Can anyone help?
