I'm trying to create a class that I can use to handle double-click events
generated by a mouse on my JTree. What I want to do is open certain panels
depending on the string value that a target node holds. One of my problems
is that I'm not sure how I need to associate the mouseClicked event I'm
making in my mouse listener class with a TreeSelectionEvent variable (to
identify where I'm currently at in the tree). This is how I'm defining my
mouse listener class, but I know I'm missing a big piece of the puzzle with
regards to TreeSelectionListener and TreeSelectionEvent:
// Define a class that can be used for double-clicking events within the
tree.
class DoubleClickedMouseListener extends MouseAdapter {
public void mouseClicked(MouseEvent me) {
if(me.getClickCount() == 2)
{
TreeSelectionEvent event = ???; // I had 'null' here just to
initialize it, but that was very wrong.
TreePath path = event.getPath();
String nodeName = path.getLastPathComponent().toString();
// getReport(nodeName);
System.out.println("You double-clicked: " + nodeName);
}
}
}
Down in my code where I'm creating all of my JTree nodes:
MouseAdapter dblClickedListener =
new DoubleClickedMouseListener();
if(dblClickedListener != null)
jTree1.addMouseListener (dblClickedListener);
Can anyone see where I'm going wrong with this? Thanks in advance.
Jeff
