QStackedWidget is a Qt widget that allows the user to stack multiple widgets on top of each other and easily switch between them. It is often used for implementing wizards or multi-step forms, where each step is represented by a different widget.
The QStackedWidget displays only one widget at a time, but all the stacked widgets are kept in memory and can be accessed and modified programmatically. The current widget can be changed using various methods such as setCurrentIndex(), setCurrentWidget(), or next() and previous().
One advantage of using QStackedWidget is that it provides an easy way to manage the layout of multiple widgets without having to manually show and hide them. It also ensures that only one widget is visible at a time, reducing clutter and improving the user experience.
Overall, QStackedWidget is a powerful tool for building complex user interfaces with multiple steps or stages, making it an essential component for many desktop applications.
