the way I deal with this is to use a switch statement on the currentState:
in init() I call registerGlobalKeyHandler()
which is
private function registerGlobalKeyHandler(): void{
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyHandler);
}
and has this event handler:
private function keyHandler(event:KeyboardEvent):void{
//handle the Enter key
if (event.keyCode == 13){
switch (currentState){
case 'login':
if ( loginButton.enabled == true ){
tryLogin();
}
break;
case 'register':
if (registerButton.enabled == true){
tryRegister();
}
break;
...
}
}
}
This gives me a lot of control over what function responds in each part of
the application, and lets me govern a variety of keys in different ways
depending on what page we're on.
You could dispense with the switch statement and have the key click work the
same everywhere.
