Usage

From source file:Main.java

/**
 * Inserts the mouse motion listener at the particular index in the listeners' chain.
 *
 * @param component/*from  w  w  w .j a  v a 2  s .  c o m*/
 * @param l
 * @param index
 */
public static void insertMouseMotionListener(Component component, MouseMotionListener l, int index) {
    MouseMotionListener[] listeners = component.getMouseMotionListeners();

    for (MouseMotionListener listener : listeners) {
        component.removeMouseMotionListener(listener);
    }

    for (int i = 0; i < listeners.length; i++) {
        MouseMotionListener listener = listeners[i];

        if (index == i) {
            component.addMouseMotionListener(l);
        }

        component.addMouseMotionListener(listener);
    }

    // inex is too large, add to the end.
    if (index > listeners.length - 1) {
