Adobe AIR(flex) accessing mxml components from classes

Hey,

So i’m working on an application and I would like to be able to access the mxml components from anywhere inside of my project, for example if I have a class I would like to be able to change labels on the GUI of the application.

I have found examples/workarounds of how to do this in Flex but as this is really an Air application they don’t work.

I was just wondering if there is any simple methods to access the GUI from inside classes and if not are there any harder/more complex methods?

Thanks, Luke
