Document

Gets this component's locking object (the object that owns the thread synchronization monitor) for AWT component-tree and layout operations.

Usage

From source file:Main.java

public static void swingDispatch(MouseEvent e, Point point, final Component component) {
    synchronized (component.getTreeLock()) {
        if (component instanceof Container) {
            Container container = (Container) component;
            for (int i = container.getComponentCount(); i-- != 0;) {
                Component child = container.getComponent(i);
                Rectangle r = child.getBounds();
                if (r.contains(point)) {
                    swingDispatch(e, new Point(point.x - r.x, point.y - r.y), child);
                    return;
                }/* w w  w . j  a  v  a  2s . c  o m*/
            }
        }
    }
    final MouseEvent adapted = convertMouseEvent(e, component, point);
    SwingUtilities.invokeLater(new Runnable() {
        public void run() {
            component.dispatchEvent(adapted);
        }
