how to show the ui and then run a loop?

[adrian88888888]

Hi!

I want to make a loop that analyzes files

Inside each iteration I want to log stuff in the ui

The problem is that I don't know where to put the loop in the code

Doesn't matter where i put it, when I run the code always starts the loop and then shows the ui

But I want the reverse: to see the ui first, and then see the loop logging in the ui

This is the bulk of the ui code, where i should put the loop?:

*lots of imports*
*lots of imports*
*lots of imports*

class MainWindow(QMainWindow):
    def __init__(self):
        QMainWindow.__init__(self)
        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)
        ...
        ...
        ...

if __name__ == "__main__":
    app = QApplication(sys.argv)
    window = MainWindow()
    window.show()
    sys.exit(app.exec_())

the simplified loop looks something like this:

for each_file in files:
    log(each_file)

Thanks!

Hi,

If you want to do heavy processing you should consider using QtConcurrent to avoid blocking your GUI

@SGaist Thanks! I will read about that

[adrian88888888]

@SGaist So you were suggesting multiprocessing? That makes sense
I know how to do that with the standard module in python: threading
That should work too?
I'm not that experienced in programming and I don't know if using the module(I guess it's called module) QtConcurrent from Qt its obligatory or not, it is?

[SGaist]

It's not obligatory but it will be better integrated and also easier to get you started since as you wrote you are new to programming.

@SGaist Thanks a lot!
