OOP function scope?

[Jhonte]

Hello, I've have started doing some OOP programming in flash8 AS 2.0 but have ran into some problem, how do you call a function in the class if it looks like this?

class someClass {
var mc:MovieClip;

public function someClass(mc:MovieClip)
{
 this.mc = mc;
this.mc.onPress = function()
{
testFunction();  // <--- here!
}


public function testFunction()
{
trace("Yes!, I was called!"); // <- Call this!
}
}
}

Maybe it is totally wrong to do like this or it is something ive missed,
I would be happy if someone could guide me to the right way of doing it!

Thanks
