Key 379
Example
The following example calls the
getCode() method any time a key is pressed. The example
creates a listener object named
keyListener and defines a function that responds to the
onKeyDown event by calling Key.getCode(). The keyListener object is then registered to
the
Key object, which broadcasts the onKeyDown message whenever a key is pressed while the
SWF file plays.
var keyListener:Object = new Object();
keyListener.onKeyDown = function() {
// Compare return value of getCode() to constant
if (Key.getCode() == Key.ENTER) {
trace ("Virtual key code: "+Key.getCode()+" (ENTER key)");
}
else {
trace("Virtual key code: "+Key.getCode());
}
};
Key.addListener(keyListener);
When using this example, make sure that you select Control > Disable Keyboard Shortcuts in
the test environment.
The following example adds a call to
Key.getAscii() to show how the two methods differ.
The main difference is that
Key.getAscii() differentiates between uppercase and lowercase
letters, and
Key.getCode() does not.
var keyListener:Object = new Object();
keyListener.onKeyDown = function() {
trace("For the last key typed:");
trace("\tThe Key code is: "+Key.getCode());
trace("\tThe ASCII value is: "+Key.getAscii());
trace("");
};
Key.addListener(keyListener);
When using this example, make sure that you select Control > Disable Keyboard Shortcuts in
the test environment.
