debugging - Mutlithreaded python application not hitting breakpoints in Visual Studio -

i developing pyqt application in visual studio. debugging has been working great, until decided keep ui responsive moving stuff worker thread qt threads.

class mainwindow(base, form):      start_work = qtcore.pyqtsignal()      def __init__(self, parent=none):         # create seperate thread in update information polled.         self.thread = qtcore.qthread()         # create worker object , move new thread         self.worker = worker()         self.worker.movetothread(self.thread)         # connect signal start work in tread         self.start_work.connect(self.worker.get_work_done)         self.thread.start()      #function emit signal start doing work     def do_work(self):         self.startwork.emit() 

any function invoked on worker object connected via signal slots

class worker(qtcore.qobject):     @qtcore.pyqtslot()     def get_work_done(self):         #lets time consuming work. 

the code works fine. problem now, cannot debug happening inside get_work_done. visual studio won't break @ breakpoints.

when break inside mainwindow function, visual studio debugger shows 1 thread. seems unaware of other threads created application. has had similar problems , knows how solve it?

debugger needs play tricks detect new threads , set hooks (which needed hit breakpoints etc). hijacking standard python _thread module. if you're creating threads in way circumvents module altogether, suspect qt here, debugger not aware of threads.

try using standard threading module instead of qthread, , see if helps.
