Hi all,

When I use GEF TreeViewer, I found it hard to expand all the tree node.

I found in org.eclipse.jface.viewers.AbstractTreeViewer, there is a
expandAll() method can expand all the tree node.

Is there a way to expand all the tree node in GEF TreeViewer?

THX

You'd have to get all the tree items, and invoke setExpanded(true) on them.
See EDiagramOutlinePage#init() for reference.
