Bar color of ProgressBar in Spark

Question

Hi,all. I use ProgressBar in Flex 3 and it's ok. I can change the bar's color by set ProgressBar's barColor style at runtime. But now I use Flex 4 and uncheck Flex 3 compatibility checkbox in Compiler configuration page, I can't use barColor style any more. I think I have to create a BarSkin class to solve it. My question is that how can I change the bar's color at runtime in Spark. I can't find any property or style for it?

Answer 1

try this solution:
create a progress bar skin and where you define the bar color write something like this:
color = {hostComponent.runtimeColor}
then create a custom component based on progress bar  or an AS3 class whitch extends progressBar like this:
package
     import mx.controls.ProgressBar;
     public class CustomProgressBar extends ProgressBar
          public var runtimeColor:uint;
          public function CustomProgressBar()
               super();
Now from your app you should change bar's color at runtime
