or if you don't want any reference of the main_window class inside the
class2 (loosing coupling) you can use a signal to implement a sort of
observer pattern [1].
class Clas2 {
public signal void update_interface (args...);
private void method2 (args...) {
update_interface (args....);
}
}
and on the main_window class you subscribe to the signal and then call method2:
class main_window:... {
public Clas2 cl;
public main_window () {
cl = new Clas2 ();
cl.update_interface.connect ((args...) => { method1 (); })
}
public void method1 () {
....
}
}
