Screenshot with Progressbar in a Tree by using TreeEditor

Hi, 

I would lie using TreeEditor to add ProgressBar in some TreeItem (see the screenshot TreeEditorProgressBar_OK.png). I have used the sample with TableEditor http://git.eclipse.org/c/platform/eclipse.platform.swt.git/tree/examples/org.eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet149.java

It works great. I have replaced Table with Tree like this : 

-----------------------------------------
		Tree tree = new Tree (sbody, SWT.BORDER);
		tree.setHeaderVisible (true);
		tree.setLinesVisible(true);
		for (int i=0; i<2; i++) {
			new TreeColumn (tree, SWT.NONE);
		}
		tree.getColumn (0).setText ("Task");
		tree.getColumn (1).setText ("Progress");
		for (int i=0; i<40; i++) {
			TreeItem item = new TreeItem (tree, SWT.NONE);
			item.setText ("Task " + i);
			if ( i % 5 == 0) {
				ProgressBar bar = new ProgressBar (tree, SWT.NONE);
				bar.setSelection (i);
				TreeEditor editor = new TreeEditor (tree);
				editor.grabHorizontal = editor.grabVertical = true;
				editor.setEditor (bar, item, 1);
			}
		}
		tree.getColumn (0).pack ();
		tree.getColumn (1).setWidth (128);
---------------------------------------

It works with RAP but if you remove the size of the first column, progressbar is not repainted and progressbar is not moved and cut the first column.
(see TreeEditorProgressBar_NOK.png)

With TableEditor you have not the problem.

After debugging, I have seen that TableColumn#setWidth call processNextColumnsMoveEvent(); method (which fix the problem) although TreeColumn#setWidht doesn't a processNextColumnsMoveEvent methdod like.
