Forcing Flex to update the screen?

Question

This may be a bit of a beginners question, but I can\'t for the life of me figure it out.

I\'m using flex to develop a GUI for a large project, specifically a status

Answer 1

Try calling invalidateDisplayList() after each changes to your progress bar. Something like :

Class StatusBar
{

    public function set progress(value:uint):void
    {
        progressBar.value = value;
        progressBar.invalidateDisplayList();
    }
}

Flex has an invalidation cycle that avoid screen redrawing everytime a property changes. As an example, if a property's value changes 3 times in a single frame, it will render only with the last value set. You can force a component to be redrawn by calling invidateDisplayList() which means updateDisplayList will be immediatly executed instead of waiting the next frame.
