Avoid "double click signal" when expanding and collapsing a branch in a TreeViewer

[Edvin Syse]

I have implemented "double click edits" in a TreeViewer. If I expand and 
collapse a branch in rapid succession, this will also trigger my double 
click handler:

    private class DoubleClickEditsAdapter extends 
ComponentMouseButtonListener.Adapter {
        public boolean mouseClick(Component component, Mouse.Button 
button, int x, int y, int count) {
            if (count == 2 && button == Mouse.Button.LEFT)
                editSelectedNode(component);
            return true;
        }
    }
I somehow have to avoid that the clicks used to expand and collapse the 
node counts as double click candidates. Any idea how I can do that?
