I am developing one python project using gui with Qt support. faced such a problem:

 while True: res = self.file.load("file.txt", isList=False) self.log("Ожидаем ввод") print("Ожидаем ввод") if res: break else: self.log("Ждём") print("Ждём") time.sleep(5)

The fact is that the print "We are waiting" and "We are waiting for input" is written to the console, but the guy dies tightly. Just hangs and that's it. What could be the problem?

    Such things need to be run in the child thread. - AlexDenisov
  • @ 1101_debian Well, if several threads, then yes. @izengardjke I don’t know qt, but in other geyas there are usually similar calls to handle accumulated events. - alexlz
  • code example using background stream and signals in qt - jfs
