Question

I have a situation where i need to implement a custom tree cell renderer.
My specification is to have only a checkbox node and text for the parent node and not the folder icon that is used in the default tree cell renderer.

I achieved it through the following code snippet.

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


    JLabel l = (JLabel)renderer.getTreeCellRendererComponent(
            tree, "", true, expanded, leaf, row, true);


    l.setIcon(null);
    l.setText(value.toString());
        panel.removeAll();
        panel.add(this, BorderLayout.WEST);
        panel.add(l);
        return panel;

}

The screen shot of the result is like this .

Now you can see the grey area enclosing the text “One” .

Can you guide me as to clear the grey area ?

The output must look something that does not have the grey around the text.

For this issue is there very simple workaround to setBackground in TreeCellRenderer with Color that returns

Color clr = UIManager.getColor("Tree.textForeground");
