Hi all,

I use GEF TreeViewer in my editor. When my editor is opened,
I want to expand all the levels of tree.

I found in org.eclipse.jface.viewers.AbstractTreeViewer, here is a
expandAll() method can implement this.
But in GEF TreeViewer, I found nothing.
Is there a way to do this, like AbstractTreeViewer#expandAll()?

In the outline I used an example which implements an ection for this:

IAction action = new Action("Expand All", img) {
public void run() {
expand(((Tree)itsViewer.getControl()).getItems());
}
private void expand(TreeItem[] items) {
for (int i = 0; i < items.length; i++) {
expand(items[i].getItems());
items[i].setExpanded(true);
}
}
};
