Usage

From source file:Main.java

/**
 * Inserts the key listener at the particular index in the listeners' chain.
 *
 * @param component/*w w w  .  ja  va  2 s  . co m*/
 * @param l
 * @param index
 */
public static void insertKeyListener(Component component, KeyListener l, int index) {
    KeyListener[] listeners = component.getKeyListeners();

    for (KeyListener listener : listeners) {
        component.removeKeyListener(listener);
    }

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

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

        component.addKeyListener(listener);
    }

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