GTK

GTK (GIMP Toolkit) is a software library used by programmers to create graphical user interfaces (GUIs), such as windows, buttons, and menus, for applications on Linux and other operating systems. It provides standardized tools and components that developers can use to build visually appealing and consistent interfaces, without having to create everything from scratch. By using GTK, developers ensure that their applications look native and function smoothly across different systems. It's an open-source project, meaning anyone can contribute to or modify it, fostering community collaboration and ongoing improvements.
