Example
The following example calls the
a trace statement any time the Caps Lock key is toggled to an active state. The example creates
a listener object named
event by calling
Key.isToggled()
object, which broadcasts the
plays.
var keyListener:Object = new Object();
keyListener.onKeyDown = function() {
if (Key.isDown(Key.CAPSLOCK)) {
trace("you pressed the Caps Lock key.");
trace("\tCaps Lock == "+Key.isToggled(Key.CAPSLOCK));
}
};
Key.addListener(keyListener);
Information displays in the Output panel when you press the Caps Lock key. The Output
panel displays either
the isToggled method.
The following example creates two text fields that update when the Caps Lock and Num Lock
keys are toggled. Each text field displays true when the key is activated, and false when the key
is deactivated.
this.createTextField("capsLock_txt", this.getNextHighestDepth(), 0, 0, 100,
22);
capsLock_txt.autoSize = true;
capsLock_txt.html = true;
this.createTextField("numLock_txt", this.getNextHighestDepth(), 0, 22, 100,
22);
numLock_txt.autoSize = true;
numLock_txt.html = true;
//
var keyListener:Object = new Object();
keyListener.onKeyDown = function() {
capsLock_txt.htmlText = "<b>Caps Lock:</b> "+Key.isToggled(Key.CAPSLOCK);
numLock_txt.htmlText = "<b>Num Lock:</b> "+Key.isToggled(144);
};
Key.addListener(keyListener);
