You want to call main_window::method1() from within Clas2::method2(), is
that correct?
Well, you cannot call non-static methods without an object,
so you will need a reference to main_window within your Clas2 object
to call method1() on. As this will setup a circular reference, you should
declare it weak, as in

 private weak main_window main_window_ref;

in Clas2, then pass the "this" reference when you create your main_window
object.
Then you can call any public method on it from Clas2.
