waitForDone() I am not compatible with gui , gui is frozen

[jsulm]

@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.

@khong-muon-them-nhieu-sai-lam said in waitForDone() I am not compatible with gui , gui is frozen:

I tried but it didn't work

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

[khong muon them nhieu sai lam]

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

[khong muon them nhieu sai lam]

@JonB @jsulm
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 ^

[SGaist]

@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.

[khong muon them nhieu sai lam]

@JonB @jsulm @SGaist @mrjj @wrosecrans
Can you give me an example? because I'm really trying to follow everyone's wishes but it's not working. or give me a reference link but what i am dealing with . pls

[JonB]

@khong-muon-them-nhieu-sai-lam
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.

[khong muon them nhieu sai lam]

@JonB
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.

[JonB]

@khong-muon-them-nhieu-sai-lam
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.
