TreeSelectionHandler and mouseovers

TreeSelectionHandler's valueChanged event is being fired whenever I move the mouse over a node. That's a problem. I have some drag-and-drop logic, and when I drag something from a higher node to a lower node, the event is being fired whenever I pass over the in-between nodes on the way to the final drop location. My program has some code for validating the drop location, but I don't want that code to run simply because I moused over a node.

I thought about writing my own MouseListener, but there's no guarantee that MouseEvent will be fired before TreeSelectionEvent.

How do I get TreeSelectionHandler to respond to an actual mouse click, rather than the "mouse entered" event?
 
I agree. Here's the link: http://aspose.com/file-tools
