How do I add Scrollbars to a JTree???

[Dirk]

I have a little problem.
I have a JInternalFrame with a JTree in it. When the JTree exceeds the
visible area there appear no scrollbars.
How do I add this scrollbar functionality to the JTree???
It would be nice if anyone can help me

Let's say you have JInternalFrame iFrame, then do -

iFrame.getContentPane()
.add(new JScrollPane(jTree), BorderLayout.CENTER);

[assuming you have BorderLayout for your contentPane]

You put the JTree into a JScrollPane.

To add scrollbars to (pretty much) any swing component place it in a
JScrollPane.

JTree someCoolTree = new JTree();
JScrollPane someCoolPane = new JScrollPane( someCoolTree );

or

JTree someCoolTree = new JTree();
JScrollPane someCoolPane = new JScrollPane();
someCoolPane.add( someCoolTree );

If you check out the Java Tutorial from java.sun.com it has some good stuff
on designing UI with swing. You may want to take a look, it has lots of good
stuff on all the swing components.

Good luck,

Hi!

Maybe you should embed your JTree within a JScrollPane...
