JTree

Posted: May 21, 2004 12:52 AM

I have a tree control that simpley reflect the files and folders present on a machine. I need to refresh a portion of the tree control so that changes made to files/folders icons are <b>auto-updated</b> in the tree control. How do i do this?

Any help will be greatly appreciated.

If I understand you right, you'll want to subclass DefaultTreeModel

Use JFileChooser. It has all the functionality that you want, moreover, there is no point in reinventing the wheel.

How can you set JFileChooser to a TreeView?

Even if that works, JFileChooser does not update the view if a file was added or removed using other programs.

It does not listen to addFile / removeFile / moveFile Events from the operating system.

JFileChooser does not update the view if a file was added or removed using other programs.

--------------------

But there is a method in JFileChooser called rescanCurrentDirectory(). Although it does not listen to add/remove/move file events, but I find that it is more than sufficient for most applications.
