I am new to using JTree in JAVA. I implemented my own FileSystemModel
that implements TreeModel. It displays directories only in the file
system. It works fine except I get

C:\Mailbox
C:\Mailbox\Inbox
C:\Mailbox\Sentbox
C:\Mailbox\Savedbox
C:\Mailbox\Savedbox\Notes


How and where do I change it so it will display

Mailbox
Inbox
Sentbox
Savedbox
Notes


Also it displays the tree collapsed when I run it. I can expand the
tree by click on the node but I would like to have an expanded tree as
a default.

Thanks for help in advance~

You should make a CellRenderer for your tree, it will display the files in a
differet way.

Thanks. It worked!!!!

public class FileSystemTreeCellRenderer extends
DefaultTreeCellRenderer {

public Component getTreeCellRendererComponent(JTree tree, Object
value,boolean selected,
boolean expanded,boolean leaf, int row, boolean hasFocus) {

super.getTreeCellRendererComponent(tree, value,
selected,expanded, leaf, row, hasFocus);

String nodeObject;
nodeObject = value.toString();
nodeObject =
nodeObject.substring(nodeObject.lastIndexOf("\\")+1);
setText(nodeObject);

return this;
}

}
