Creating Powerful GUI’s with PyQt6: QCheckBox and QComboBox

PyQt6 is a powerful GUI toolkit for Python that allows you to create stunning and interactive user interfaces. In this article, we will explore two essential widgets in PyQt6 – QCheckBox and QComboBox.

QCheckBox

QCheckBox is a simple widget that allows the user to toggle between two states – checked and unchecked. It is commonly used for binary choices or options.

To create a QCheckBox in PyQt6, you can use the following code:


import sys
from PyQt6.QtWidgets import QApplication, QCheckBox

app = QApplication(sys.argv)

checkbox = QCheckBox('Enable Feature', checked=True)
checkbox.show()

sys.exit(app.exec())


This code creates a QCheckBox with the label ‘Enable Feature’ and sets it to be checked by default. You can toggle the state of the checkbox by clicking on it.

QComboBox

QComboBox is a dropdown list widget that allows the user to select one option from a list of choices. It is commonly used for selecting from a set of predefined values.

To create a QComboBox in PyQt6, you can use the following code:


import sys
from PyQt6.QtWidgets import QApplication, QComboBox

app = QApplication(sys.argv)

combobox = QComboBox()
combobox.addItems(['Option 1', 'Option 2', 'Option 3'])
combobox.show()

sys.exit(app.exec())


This code creates a QComboBox with three options – ‘Option 1’, ‘Option 2’, and ‘Option 3’. The user can select one option from the dropdown list.

Conclusion

QCheckBox and QComboBox are essential widgets in PyQt6 that allow you to create powerful and interactive user interfaces. By leveraging these widgets, you can build sophisticated GUI applications with ease.
