Mastering GUI Programming with Python

The initial setup

First, make a fresh copy of the application template and call it soundboard.py. Then, import QtMultimedia as you did for the last project, and let's layout the main interface.

Inside the MainWindow constructor, add in the following code:

        rows = 3        columns = 3        soundboard = qtw.QWidget()        soundboard.setLayout(qtw.QGridLayout())        self.setCentralWidget(soundboard)        for c in range(columns):            for r in range(rows):                sw = SoundWidget()                soundboard.layout().addWidget(sw, c, r)

All we're doing here is creating an empty central widget, adding a grid layout, and then filling it with 3 rows and 3 columns of SoundWidget objects.
