JTree as drop target: use cell renderer ?

Hi all,

Can I use my custom cell renderer as a drop target ?
I was hoping to get access to the actual node dropped
on by something like this, instead of using the JTree
and getPathForLocation( x, y)...

I tried to use the cell renderer, and it doesn't work,
my guess would be that the JTree doesn't allow the
relevant events to propogate down far enough.
Any insights/recommendations ?
Thanks

cell renderer is not really shown/ added to JTree as child component. It is
used only to paint cell region, but it is painting on JTree component.
That's why you can't attach drop or any other evenets to renderer, you have
to do it on Jtree component and then use getPathForLocation( x, y) to find
out which cell is relevant for the event. With all other mouse events like
mouse clicks, mouse moves etc. you have to use same method.
