You'd design your model to keep track of which nodes were visited, and provide a custom renderer for the tree. - Oliver Back to top Sharon Guest Posted: Sun May 14, 2006 9:07 pm    Post subject: Re: paint visited leaf's in JTree Hi Oliver and thank you I have custom renderer , and I have a HashMap that saves the path of the visited Leaf But how dose the actual painting occurs?

You have your method getTreeCellRendererComponent( ... ) in there you can either ask the tree for the model, "talk to" the model some other way. if you just extend the DefaultTreeCellRenderer it is a JLabel, so there you can change the colour easily. something like if(visited){ super.setForeground(ColorRED); }else{ super.setForeground(Color.BLUE); } regards Daniel Quote: Hi Oliver and thank you I have custom renderer , and I have a HashMap that saves the path of the visited Leaf But how dose the actual painting occurs?
