Question

I am unable to add action listener to a particular node in the tree. This is a tree that i’ve constructed :

I want to register a separate listener for each node . Now i have registered a listener on JTree. so, whenever i click on any portion of tree the listener method starts it’s work. (i.e now i have a common listener )
What i want is when i click on audio a listener registered to hear audio click, should start it’s work and the same goes for video. How can i do that ?

This is how i have registered so far :

jTree1.addTreeSelectionListener(new javax.swing.event.TreeSelectionListener() {
        public void valueChanged(javax.swing.event.TreeSelectionEvent evt) {
            jTree1ValueChanged(evt);
        }
    });
public void jTree1ValueChanged( TreeSelectionEvent tse ) {...}

Answer 1

What about this. Or do you have special PathComponents?

public void jTree1ValueChanged( TreeSelectionEvent tse ) {
     String node = tse.getNewLeadSelectionPath().getLastPathComponent().toString();
    if( node.equals("audio") ) {
        // play audio
    } else if( node.equals("video") ) {
       // play video
    }
}
