Hi,
I am having two different type of nodes
1.which are always leaf i.e. can not have children.
2. Which can have children and may be leaf.
So i want to distinguish these 2 type of nodes so that the user may know which can have children and which can not. This difference can be either with a color or icon or anything. I have set setAllowsChildren(true/false), correspondingly also.DefaultTreeCellRenderer won't work ciz that too will set the color of all the leaves same.
SO
if anybody can help me out, i'll be thankful
regards
Gautam
