👉 GTK (Graphical Toolkit) is a cross-platform application framework for developing graphical user interfaces (GUIs) in various operating systems, including Linux, macOS, and Windows. It provides a comprehensive set of tools, libraries, and widgets that enable developers to create visually appealing and functional applications with ease. GTK operates by defining a set of application structures, signals, and callbacks that facilitate communication between different parts of the application. It supports event-driven programming, allowing applications to respond dynamically to user interactions such as button clicks, keyboard input, and mouse movements. GTK's modular design allows for easy customization and extension, making it a popular choice for creating desktop applications that are both robust and user-friendly.
