Lets put a little pizazz in the Flex download ProgressBar. Really, going from, say, 0 -> 100 is great and all but maybe you need more. Like how about changing colors as it gets closer to completion?

Now that’s more like it.

The meat and potatoes of this is in the following two methods:

private function onSlider():void {
progressBar.setProgress( slider.value, 100 );
// this will fade from 0 = green, to 100 = red
_barColor = rgbToHex( 0xFF * ( slider.value / 100 ), // this is the red part
0x00FF * ( ( 100 - slider.value ) / 100 ), // green
0 ); // no blue for you!
}
private function rgbToHex( R:uint, G:uint, B:uint ):uint {
return( R << 16 | G << 8 | B );
}
