@Override
public void hierarchyChanged(HierarchyEvent e) {
    System.out.println("Components Change: " + e.getChanged());
    if ((e.getChangeFlags() & HierarchyEvent.DISPLAYABILITY_CHANGED) != 0) {
        if (e.getComponent().isDisplayable()) {
            System.out.println("Components DISPLAYABILITY_CHANGED : " + e.getChanged());
        } else {/*from w  w  w.j a v a 2s.  c o m*/
            System.out.println("Components DISPLAYABILITY_CHANGED : " + e.getChanged());
