[flexcoders] How can I call a function from a class?

[sailorsea21]

Hi everyone, How can I call a function from a class?

////// MAIN FILE
import test.layout; 

private function callClassFunction():void
{
        test.layout_QT.traceTest();
}



////// CLASS FILE layout.as
package test
{
        public class layout
        {
                public function traceTest():void
                {
                      trace("This is a test.");
                }
        }
}

Thanks.
