    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
