Hi,

did any of you ever do a TreeView where the nodes can be dragged-and-dropped?

If not, what would be the general idea of how to go about this?

I don't think that the Notifier could be used, because by releasing the button, the tree.Selected() does not change.

Using the DropMsg doesn't work, because the view is the Tree, and not the node, so it does not fire in this case.

Two ways I thought of:
a) Using the notifier and a RM interclick. Both mousekey actions result in the op parameter of the notifier. So the second mouse down (in this case: right mouse down) would happen before the first mouse up.

b) Using two parallel TreeViews on the same Dialog.Tree variable, so that the DropMsg kann be used.

c) using a wrapper handling the control messages.

Solution a is not really a drag-and-drop, though, solution b is really awkward, IMHO, and I have no idea about solution c.

Any better ideas?

Rene
