FilteredTree with TreeViewerColumns? [message #780042]

I have a TreeViewer with TreeViewerColumns work fine.
I'd like to try using a FilteredTree.
I haven't yet found a way to do that, as FilteredTree apparently doesn't use a TreeColumnLayout(). I found some example code to handle that, but it just results in a blank view.

My original TreeViewer

tcl_composite = new TreeColumnLayout();
composite.setLayout(tcl_composite);
mtreeViewer = new TreeViewer(composite, SWT.BORDER | SWT.FULL_SELECTION);

What I tried replacing it with:

tcl_composite = new TreeColumnLayout();
mFilteredTree = new FilteredTree( composite, SWT.BORDER | SWT.FULL_SELECTION, new PatternFilter(), true){
	@Override
	protected Control createTreeControl(Composite parent, int style) {
		Control c = super.createTreeControl(parent, style);
		c.setLayoutData(null);
		c.getParent().setLayout(tcl_composite);
		return c;
		}
	};
mtreeViewer = mFilteredTree.getViewer();

So, how am I supposed to use TreeColumnViewers with a FilteredTree?
