QRegion in C++ is a class that represents a region or a geometric shape which can be used for clipping or painting in graphical applications. It provides a flexible way to define complex areas by combining or subtracting different shapes such as rectangles, ellipses, and polygons. This allows for efficient processing and manipulation of regions, enabling developers to perform operations such as intersection, union, and exclusion. QRegion is commonly used in GUI frameworks like Qt to handle graphical operations and optimize rendering, providing efficient representation and processing of regions for various graphical tasks.
