Hello, I will explain the progressbar topic. You can guess where it is used.for example, when you download a file from the internet, you want to see what % , or when you copy a file from one place to another, it appears when you copy it.
It can be used in almost all of the process processes.
Example :
progressbar object
self.progress_bar = QProgressBar(self)
While setting new value to the progressbar object
self.progress_bar.setValue(startVal)
Result :
