Question

I just thought it would be useful to know how to check if an swf has been focused or otherwise. This situation arises when the end user clicks outside of the stage (on the address bar of the browser, for example).

Answer 1

stage.addEventListener(Event.DEACTIVATE, notFocused);
stage.addEventListener(Event.ACTIVATE, focused);
function notFocused(e:Event) {
    trace("Not focused");
}
function focused(e:Event) {
    trace("Focused");
}
