What is GTK and how does it work?
GTK is a free and open-source cross-platform widget toolkit for creating graphical user interfaces. It works by providing a set of libraries and tools that allow developers to build GUI applications with a native look and feel on various platforms, including Windows, macOS, and Linux. GTK achieves this by abstracting the underlying platform-specific details, allowing developers to focus on writing application code.
GTK’s architecture is based on a object-oriented programming model, where widgets are represented as objects that can be instantiated, configured, and composed to create complex user interfaces. The toolkit also provides a comprehensive set of APIs for handling events, managing layouts, and rendering graphics. By leveraging GTK’s APIs and libraries, developers can create high-quality, platform-independent GUI applications with ease.
