Find out if a component is in a specific container

Question

I have an application with a lot of swing components nested in several containers. I implement a pop-up menu with a right click, showing information based on the context in which the component is located.

To give an example: If I right-click on a JTextField, I want to display "foo" in a popup window if the text field is inside JScrollPane and "bar" if it is not. But JTextField itself can be nested in several other JPanels.

I could do something like this:

public static boolean isInScrollPane(JComponent comp) {

    Container c = comp.getParent();

    while (c != null) {         
        if (c instanceof JScrollPane) {
            return true;
        } else {
            c = c.getParent();
        }
    }
    return false;
}

But I'm sure there is a much better solution that is already available, and I just did not find it.

Can someone please give me a hint?

SwingUtilies.getAncestorOfClass(). :

public static boolean isInScrollPane(JComponent comp)
{
  return SwingUtilities.getAncestorOfClass(JScrollPane.class, comp) != null;
}
