manually trigger tooltips

Any way to trigger the tooltips for JComponents whenever I want, and not just on mouseover event?

Code:

---

Action toolTipAction = component.getActionMap().get("postTip");

if (toolTipAction != null)
{
        ActionEvent postTip = new ActionEvent(component, ActionEvent.ACTION_PERFORMED, "");
        toolTipAction.actionPerformed( postTip );
}
