C++ Programming By Example - Reacting to User Input

The video tutorial explains how to handle user mouse inputs in a QGIS application. It covers the documentation for mouse events, specifically focusing on mouse press, move, and release events. The tutorial demonstrates how to implement these events in Visual Studio, test them, and understand the coordinate system. It also prepares for drawing on the widget by setting up a boolean flag to ensure drawing occurs only when the mouse is pressed.
