[flexcoders] How can I pass a var to a class???

[sailorsea21]

Hi everyone, is it possible to pass a variable when I call a class???

This is what I'm doing:

bar.setStyle('itemRenderer', new ClassFactory(BarColorRenderer));

My class is 'BarColorRenderer' and I would like to also pass it a variable. Is 
it possible? 

This is my class:

public class BarColorRenderer extends mx.skins.ProgrammaticSkin implements 
IDataRenderer 
{                           
public function BarColorRenderer()
{
}
}

Thanks everyone.
