Thanks for this work. I'll look at it later this week. I'm about to leave for the airport now. It would be simpler to base any new version on the present code: otherwise you risk trying to keep pace with what I have just done. There is only one aspect of the tree widget that I am considering improving. Rather than redrawing the entire tree, the widget should redraw only needed sections. Just a couple of days ago I saw how to do so cleanly. The essential part of the redrawing algorithm is drawing a list of siblings. If the to-be-drawn siblings match the existing sibs, do nothing. Otherwise, the algorithm can try to be "clever" by detecting inserted, deleted or moved siblings, or the algorithm can simply redraw all the siblings, along with their *entire* subtrees. This scheme is simple, and will be *much* more efficient than the present scheme. Furthermore, no redraw will ever be needed when a tree item is expanded. > I would also like to suggest that qt leo moves to using dockable widgets for the layout instead of splitters.

I don't see the utility of that, but again, a demo would be good. > Perhaps you could suggest where I might best fit into your project? Base any demo on the existing plugin.
