How can I use two different ToolTipUIs?

Question

Hi,
I want to use two different ToolTipUIs depending (in my case) on the JRadioButton that the Cursor is hovering over. For some JRadioButtons, I want to use the default ToolTipUI, and for others I wish to display a large amount of text over multiple lines. It seems to me that this is not easily possible as ToolTipManager uses the same JTooltip for each component, so setting the UI for JToolTip will affect every tool-tip-text.
Does anyone know of a simple method to achieve this goal? Or can someone please correct me if my understanding is wrong?!
And yes, I do realise that I could just use the multi-line ToolTipUI for all tooltips.
Thanks,
Muel.

As a point of interest, does anyone know why JToolTip doesn't have a public setUI(ComponentUI) method? Most other JComponents have such a method. This is really annoying because it means you have to do 1 of 2 things:
1. Subclass JToolTip and subclass the particular JComponent
public class WrappableToolTip extends JToolTip {
     public void setUI(ComponentUI ui) {
          super.setUI(ui);
} //end class
// and the subclass of the JComponent
public class WrapToolTipRadioButton extends JRadioButton {
     public WrapToolTipRadioButton(String text) {
          super(text);
     public JToolTip createToolTip() {
          JToolTip toolTip = new WrappableToolTip();
          toolTip.setComponent(this);
          toolTip.setUI(new WrappableToolTipUI());
          return toolTip;
} //end class
2. Rank work around in particular JComponent
public class WrapToolTipRadioButton extends JRadioButton {
     public WrapToolTipRadioButton(String text) {
          super(text);
     public JToolTip createToolTip() {
          JToolTip toolTip = super.createToolTip();
          ComponentUI oldUI = UIManager.getUI(toolTip);
          UIManager.put("ToolTipUI", WrappableToolTipUI.class.getName());
          toolTip.updateUI();
          UIManager.put("ToolTipUI", oldUI.getClass().getName());
          return toolTip;
} //end classThis problem is really annoying, because I have to write 2 or 3 (depending on above methods) classes for something simple. If it were a different component, I'd just have to write 1 class - the UI class. Irritating!
