Is it possible to have different size for a combobox and its popup?

Question

Hello,
I am showing a JComboBox with all possible fonts. Some of the font names are very long. I'd like to show a narrower combobox but when the popup menu is open to make as wide as necessary.
Is that possible?
Thanks.

Hi.
I found this a while ago, but never used it myself:// A Custom UI for the combo box popup
private static class PopupExpandingComboBoxUI extends WindowsComboBoxUI
protected ComboPopup createPopup()
return new ExpandingComboPopup(comboBox);
// Our custom popup menu - it makes up its own width
private static class ExpandingComboPopup extends BasicComboPopup
public ExpandingComboPopup(JComboBox cBox)
super(cBox);
public Rectangle computePopupBounds(int px, int py, int pw, int ph)
// Ok - just set the popup width to 200 for now - should be calculated though
return super.computePopupBounds(px, py, 200, ph);
}
