It is the destination that gives me the rub. I have docking panes that users can move around. I want to simulate moving these docking panes and dropping them on an object which will dock it. If there was a way I could calculate the distance from where I am to the object I wanted to go to, that would be grand. Hmmm, I will give that some thought. Between the container objects and the destination object itself, I may be able to do just that.
Off I go to the drawing board. Thanks for the tip.
