how to show the ui and then run a loop?

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!
