Question

I’m trying to make my own button in flash application. Here is some code:

addEventListener(MouseEvent.MOUSE_OUT, Out);
addEventListener(MouseEvent.MOUSE_OVER, Over);

...

private function Over(event:MouseEvent):void
{
    addChild(overImage);
}

private function Out(event:MouseEvent):void
{
    removeChild(overImage);
}

When mouse is over this button, overImage is blinking. Looks like Over and Out are calling each frame. What am I doing wrong?

Answer 1

If the mouse is positioned in a point where overImage will appear, then that child object will cause a MOUSE_OVER event on itself and thus a MOUSE_OUT event on its parent. The parent MOUSE_OUT will remove the overImage from the display list and that wil cause again a MOUSE_OVER over the parent, startin the loop once again and making the overImage to blink.
