    I explained earlier. Told you not to use waitFor...() and to use signals instead. "I cannot use your suggested method because it still freezes the GUI." but now you admit you have put waitFor...() in. Suggested the code you will need. Up to you.

    i used your method but it can't solve my problem
    i have listened to you .but still not working. or i wrote the wrong code . I hope there is another workaround to make the gui not freeze. Thank you very much for helping me.

      @khong-muon-them-nhieu-sai-lam No need for any workaround. Simply use Qt properly: use signals and slots just like @JonB suggested. If your current code does not work then please post it.

          Can you please also tell us in what way it "didn't work"? What happens now?

            it doesn't freeze the gui . but it runs continuously and doesn't stop for thread A to finish and then thread B

              test my code . It still doesn't work even though I tried to follow everyone's advice. I'm still trying to solve it. still don't understand how waitfordone and wait are used in any case ^

                @khong-muon-them-nhieu-sai-lam hi, you are not chaining anything hence it can't work the way you expect them to.

                On a side note, retranslateUI is not the place to the initialisation/connections you have put there.

                Another note, your RunnerSignals class has no reason to exist and its usage is wrong. QThread is a QObject and you can define signals directly in it.

                    Told you to do

                    self.worker1.signals.finished.connect(self.someMethodWhichStartsTheNextThread)    # or you can use a Python *lambda* here
                    

                    What have you done about connecting the starting of the second thread when the first thread finishes as above, show us where you have done this? Since you don't seem to have done so the second thread won't start. Don't know what "reference link" you are expecting, just implement it.

                      The issue here is that I don't just run one specific thread, but I run a group of threads! The way you showed me only performs a certain thread, not a group of threads. I need to run a group of threads altogether and continue to run another group of threads after that.

                        So apply the same principle except that you need to count/mark off as each thread finishes so that you will know when they have all finished, then spawn off the next group of threads when the last one in the first group finishes.
