How to check the mouse is over something clickable?

Question

I'm building a specialized viewer application which loads external SWFs.

var content:Sprite = ...
content.addChild(loader);

I listen to my top level content Sprite MOUSE_OVER and MOUSE_OUT events. The over handler hides default cursor and displays a custom (zoom) cursor. Out handler changes cursor back to default.

What I want to achieve is NOT showing the zoom cursor when the mouse is over a clickable item in the externally loaded SWF like a button or textlink.

The current code works perfectly for AVM1 swfs. The problem lies with loaded swfs using AS3. For these the content MOUSE_OUT is fired and instantly MOUSE_OVER is fired as well, so the cursor remains wrong.

What this probably boils down to is: How to check the mouse is over a clickable child of content?

Answer 1

With some testing and the hint George gave me, this is the content MOUSE_OVER listener I just wrote (in Haxe) which seems to work:

public var mouseOverClickableContent:Bool;

private function onOverContentChild(event)
{   
    mouseOverClickableContent = false;
    if (event.target != content)
    {
        var obj:flash.display.InteractiveObject = cast event.target;

        while (obj != content)
        {
            if (   obj.hasEventListener(flash.events.MouseEvent.CLICK)
                || obj.hasEventListener(flash.events.MouseEvent.MOUSE_UP)
                || obj.hasEventListener(flash.events.MouseEvent.MOUSE_DOWN)
                || ( Std.is(obj, Sprite) && cast(obj, Sprite).buttonMode )
            ){
                mouseOverClickableContent = true;
                break;
            }
            obj = obj.parent;
        }
    }


}

Unfortunately, there seems to be no way of detecting if the mouse is over a TextField htmlText link, so I could add a TextField htmlText.indexOf("<a") != -1 check there.

Unless someone knows a trick to detect mouse-over-textfield-links?
