[Tutor] While Loop and Threads

[Oğuzhan Öğreden]

Hi,

I've been practicing with multithreading and gtk for a while and recently
have observed something I can't quite grasp.

This is basically a timer with a settings window and a countdown window
which is produced after setting_window passes necessary arguments to thread.

I have a while loop which counts time, inside the thread, while variable
"runner" is True, which looks like this:

    def run(self):
        cycle = ['work', 'break', 'long_break']
        cycle = cycle[:2]*self.workn+cycle[3]
        self.runner = True
        sec_count = timedelta(seconds=1)

        while self.runner == True:
            for i in cycle:
                self.setState(i)
                print('Start:', i, datetime.now())

                while self.end_time > datetime.now():
                    time.sleep(1)
                    self.duration -= sec_count

                self.count[self.state] += 1

And I want countdown to stop when countdown_window receives delete event,
thus I have a countdown_window.stop() function which is defined as follows:

def stop(self, *args):
        pom.count[pom.state] -= 1
        pom.runner = False # refers to the runner of the thread.
        print(pom.runner) # prints False,
        Gtk.main_quit()

What I expect to happen is that while loop to break, but it does not.

Any suggestions?

Best,
Oğuzhan
