[AS3] key/focus problem

[ImprisonedPride]

Yeah already found it meanwhile, not much more info indeed.

I just noticed another prob, which should also occur with the senocular class you use (mine is very similar, but I wrote it before he posted his class way back when). When you right click, the deactivate event isn't called, so keys can still get stuck. I'm having trouble finding a on-contextmenu event, but it's probably in there somewhere. Any ideas would be appreciated.

Maybe?

stage.addEventListener(MouseEvent.RIGHT_CLICK, clearKeys);

private static function clearKeys(event:MouseEvent):void {
    keysDown = new Object();
}

Should clear any keydef's the class is holding onto if you right click, but it's off the top of my head because I don't have time to test it.

Got the same problem, just find why. Focus on a object (sprite, mc, whatever) that you remove from stage and got garbage collect. Boom, loose stage focus.

OMG, thank you very much.
This really helped me to fix my problem .
Now after removeChild() I'm setting stage.focus = stage; and I know why it works which is important for me

I had this problem earlier today and found the best way around it was..

//add a listener to check for focus loss
stage.addEventListener(FocusEvent.FOCUS_OUT, focusOut);

//reset focus when lost
public function focusOut(e:FocusEvent):void
{
    stage.focus = stage;
}

Sorry for digging up this old thread, but I just ran into this issue, and I think there is another way to fix it, that might be better in most cases:

The flash component like a button or whatever seems to capture the event and stops its propagation. So it will never bubble up to the stage Object.

But don't forget: An event in Actionscript has 2 phases: the bubble phase, and the capture phase.
First, the event goes down from the stage to the element that is the target of the event. Then, it bubbles up again to the stage.
So just put your eventlistener in front into the capture phase, and you will be fine

this.stage.addEventListener(KeyboardEvent.KEY_DOWN, this.keyDown, true);

The true is the useCapture param.
Also, if your "this" might get removed from stage, it is good practice to make the event listener a weak reference, so the object can be collected by the garbagecollector:

this.stage.addEventListener(KeyboardEvent.KEY_DOWN, this.keyDown, true, 0, true);

im having the same problem, im gonna see if stage.focus=stage fixes it...

edit*** yup adding that before I call the creation of any other sprites in my enterframe function fixes all problems...
