PytQt5 Live Audio GUI with start and stop buttons | QThreadPool: PyQt5 tutorial - Part 11

Hello friends, this tutorial is an update of the previous tutorial No. 10. Like before, we will get data from the live audio stream through the computer’s microphone. We have another button named “Stop” added to this GUI. This button will stop the current worker and let the user update the parameters in the GUI. This tutorial includes basics about the QThreadPool and how to stop the worker.

In QtDesigner, I dragged a generic Widget (called it "graphWidget"), then promoted it from its baseclass of QWidget to my own class "PlotWidget". I then can load it via:

from pyqtgraph import PlotWidget, plot
...
class
self.mainbox = uic.loadUi('mainwindow.ui', self)

self.plot([1, 2, 3, 4, 5, 6, 7, 8, 9, 10], [30, 32, 34, 32, 33, 31, 29, 32, 35, 45])

But, how would you add a button or label to the central widget's layout?
self.label = QtWidgets.QLabel()


For example, none of these work:




Do I need to create a new layout using setCentralWidget or setLayout?
vLayout = QVBoxLayout ()
vLayout.addWidget( loadUi( 'mainwindow.ui' ) )
