Source Link

Document

Unregisters listener so that it will no longer receive AncestorEvents.

Usage

From source file:Main.java

public static void requestFocusOnDisplay(JComponent c) {
    final JComponent c2 = c;

    c2.addAncestorListener(new javax.swing.event.AncestorListener() {
        public void ancestorAdded(javax.swing.event.AncestorEvent event) {
            c2.requestFocus();//from ww w. j  a  v a  2  s.c om
            c2.removeAncestorListener(this);
        }

        public void ancestorRemoved(javax.swing.event.AncestorEvent event) {
        }

        public void ancestorMoved(javax.swing.event.AncestorEvent event) {
        }
    });
