How to keep the window focus on new Toplevel() window in Tkinter?

Question

I am currently writing a win32gui python27 application (I\'m running win7). I am wondering if it is possible to create a new window from my mainloop() and KEEPING the focus

Answer 1

None of the above suggestions worked for me, on Mac OS El Capitan. But based on those hints, this does:

class Window(Tk.Toplevel):
    ...
    def setActive(self):
        self.lift()
        self.focus_force()
        self.grab_set()
        self.grab_release()
    ...
