Event-Driven Programming: Introduction to GTKmm4

This lecture introduces the concept of event-driven programming using GTKmm4, focusing on non-blocking input methods. The instructor explains the principles of event handling, emphasizing the importance of managing user interactions without halting program execution. Key topics include the structure of an interactive graphical program, the role of the main application loop, and how events are queued and processed. The lecture covers practical examples, such as the implementation of a drawing area and buttons that trigger actions like clearing or redrawing. The instructor also discusses the significance of signal handlers and callbacks in responding to user inputs, illustrating how events are generated and handled in real-time. By the end of the lecture, students gain a clear understanding of how to create responsive applications using GTKmm4, along with insights into the design of graphical interfaces using containers. This foundational knowledge prepares students for more complex programming tasks in future projects.
