Question

I need to check from javascript that given flash object is in fullscreen mode. I know that there is stage.displayState property but how to access it using GetVariable? Or maybe there is another way?

Thanks.

P.S. If your know how to do that from any other language it is ok too.

Answer 1

you’ll probably need to add a function inside AS that you can call from the JS layer:

// In your AS code
import flash.external.ExternalInterface;
import flash.display.StageDisplayState;

// Register a function you can call from JS
ExternalInterface.addCallback("isFullScreen", _isFullScreen);

// Returns true if fullscreen
private function _isFullScreen() :Boolean {
    return stage.displayState === StageDisplayState.FULL_SCREEN:
};

then, you should be able to call it from JS:

// Get a reference to the object element, change
// 'flashcontent' to the ID of your .swf in the DOM
var o = document.getElementById('flashcontent'),
    // Figure out it the player is in fullscreen mode
    isFullScreen = o.isFullScreen();
// Do something with isFullScreen value

docs for ExternalInterface here, stage display state here.

hope that helps. cheers!
