Understand how we use QButton, QHBoxLayout, and QVBoxLayout widgets in our GUI applications.

We'll cover the following...

The QButtonGroup class

It's common to group some checkboxes or buttons to manage them more easily. Fortunately, PyQt offers the QButtonGroup class that can be used to group and organize buttons and make them mutually exclusive. This is also useful if you want one checkbox selected at a time.

QButtonGroup is a container to which widgets can be added rather than being a widget itself. As a result, adding QButtonGroup to a layout is not possible. The way for importing and setting up QButtonGroup in your program is demonstrated by the code below:

Press + to interact
from PyQt6.QtWidgets import QButtonGroup, QCheckBox
b_group = QButtonGroup() # Create instance of QButtonGroup
# Create two checkboxes
cb_1 = QCheckBox("CB 1")
cb_2 = QCheckBox("CB 2")
# Add checkboxes into QButtonGroup
b_group.addButton(cb_1)
b_group.addButton(cb_2)
# Connect all buttons in a group to one signal
b_group.buttonClicked.connect(cbClicked)
def cbClicked(cb):
  print(cb)
