Hi,
I want to draw a tree like structure as shown in this link:

I am using GEF/Draw2D to build this. I want to display tree like structure
and also then want to listen to changes if any TreeItem is selected.

In a nutshell, I want the power of DefaultMutableTreeNode, TreeModel,
JTree as present in SWING. I want the similar power in Draw2D. This is
because, I just don't want to display it. I want to listen to the actions
and perform some changes (just like we do other thing sin GEF , the M-V-C
kind of a thing).

How to do the above thing?

Thanks,
Aatish

Hi Attish

There is a very nice tree example in the draw2d examples.

Cheers...
