PyQt5 Application Dark Mode Setup

PyQt5 is a popular Python library for creating graphical user interfaces. One of the key features that users often look for in applications is the ability to switch between light and dark modes.

Setting Up Dark Mode in PyQt5

Setting up dark mode in a PyQt5 application is actually quite simple. With just a few lines of code, you can allow users to switch between light and dark modes seamlessly.

Code Example

        
            from PyQt5.QtWidgets import QApplication, QStyleFactory, QCheckBox

            app = QApplication([])
            app.setStyle(QStyleFactory.create('Fusion'))

            checkbox = QCheckBox('Dark Mode')
            checkbox.setChecked(True)  # set to True for dark mode by default

            checkbox.toggled.connect(lambda checked: app.setStyleSheet('QCheckBox { background: #333; color: #fff; }'))

            checkbox.show()

            app.exec_()
        
    

In the code above, we are using the Fusion style to create our application. We then create a checkbox widget that allows users to toggle dark mode on and off. When the checkbox is toggled, we use a lambda function to change the application’s stylesheet to apply the dark mode theme.

Conclusion

With just a few lines of code, you can easily set up dark mode in your PyQt5 applications. This is just one of the many features that makes PyQt5 a great choice for creating user-friendly and customizable graphical user interfaces.

So, start implementing dark mode in your PyQt5 applications and provide your users with a more comfortable and customizable user interface experience.
