As far as I remember what you suggest would be perfect solution for
Java. In other words it's a matter of getting a reference to "a"
(the instance of class A) and your variant just one of the others
possible. Maybe I came up with not very good example, so maybe I try to
explain it verbally.
As I already have written I play with Tkinter and make an application
that does some stuff. It uses dynamic GUI building depending on data it
process. Also one of the requriments is to separate the program logic
from GUI.
Here is a short illustration:
...
self.b=Tkinter.Button(root,txt="Button",command=self.doSmth).pack()
self.l=Tkinter.Label(root,txt="default").pack()
def doSmth(self):
var=globals()["m"].__dict__["progLogic"].func("some
input")
self.l.config(txt=var)
self.l.update_idletasks()
...
I guess it's all correct or at least it close to what I work on. What
do you think? If I may I'd say it again that GUI is built according by
the data that's passed by the "thinking" part of the program so I
don't necessary know what it is (can only guess) and that's why passing
references as an argument doesn't seem possible.
