listen for dispatchEvent and run a function?

[mgason]

Hi,
if I have a class I load,
import com.pixelator;//import explosion class

In my movie I want to run a function when it finishes and dispatches the event below. How do I do that?

here is the code from the class

function completeHandler() {
                dispatchEvent(new Event("PIXELS_DONE"));
} 

thanks mark
