In the sub_window.dosumfunction() method, you cannot easily get access to the
widget itself.

Really, you should avoid modifying the code generated by pyuic4 and instead
create new widget classes where you define new methods. This approach allows
you to change the UI in Designer and regenerate the code without having to
edit the file again.

There seems to be many assignments to self and Form, and it isn't clear to me
what you wrote and what pyuic4 wrote. Anyway, I modified the code a little so
that it works, but the code could be improved:

It might be useful for you to look at some tutorials for Designer and pyuic4.
