Setting the auto expand level of the Outline [message #513517]

I would like to set the auto expand level of the outline viewer to only expand the top level elements.

To achieve this I used registerSpecialToolbarActions method of my OutlinePage and put the line

	@Override
	protected void registerSpecialToolbarActions(IActionBars actionBars)
	{
		fOutlineViewer.setAutoExpandLevel(2);
		...
	}

I did it this way because this is the only method called between the outline viewer creation and the call to setInput.

This works fine, but I'm wondering if there is a more elegant way to do it.

If not, can you provide a way to customize this behavior ?
