Jtree change a node

[Mike Brooks]

Hey,

I am writing a program that display a Jtree and in doing so i would like to change the name of the node from file to a string. The reason i make it a file in the first place is so that it give me the folder icon if it is a directory etc.. The problem is i don t want to show the full file path in the Jtree so I change the name of the node but when i do this the icon can change as the name is no longer a file.

Is there a way to lock the DefaultTreeCellRenderer so that node does not change or is there a better way to change the name so that the DefaultTreeCellRenderer does not change the icon

Please any help would be much appreciated.

We use a custom cell renderer, something like this:

tree.setCellRenderer(new DefaultTreeCellRenderer() {
    @Override
    public Component getTreeCellRendererComponent(JTree tree, Object value,
            boolean sel, boolean expanded, boolean leaf, int row, boolean hasFocus) {
        super.getTreeCellRendererComponent(tree, value, sel, expanded, leaf, row, hasFocus);
        Object userObject = ((DefaultMutableTreeNode) value).getUserObject();
        if (userObject instanceof File) {
            setIcon(FileSystemView.getFileSystemView().getSystemIcon((File) userObject));
            setText(((File)userObject).getName());
        }
        return this;
    }
});

You can then use the toString() menthod on the userObject and make a file to check if it is a file instead of referencing the Object
