change the icon of a JTree parent node according to its child nodes

[esamsalah]

Dear All

I am using SWING , JTree , in a software app. to monitor some hardware
devices using SNMP

I am organizing the devices in a JTree subclass

I have a parent node with some child nodes

I need to change the parent-node's icon according to some conditions in
its child-nodes

for example :
when a child-node.getX() > 1000
then its parent-node.icon should be changed

I think that I need to handle the paint of the parent-node but I don't
know how ?

Do I need to have subclasses of TreeNode for both Parent and Child
nodes ?? I am using the MutableTreeNode for all my nodes !

Thanks in advance

Essam
