Versions:
gtkmm 2.22.0-2 is the official C++ binding for the GTK graphical user-interface toolkit maintained by the GNOME Project. Packaged as a single-version Windows release, it provides object-oriented wrappers that let developers create native-looking desktop applications entirely in modern C++ without calling the underlying C API directly. Typical use cases range from small utilities and audio editors to full productivity suites that must run identically across GNOME-based Linux systems and Windows desktops. Because the library maps GTK widgets, signals, and layout containers into intuitive C++ classes, programmers can leverage standard features such as type safety, inheritance, and RAII while still benefiting from GTK’s theming engine, internationalization support, and broad widget set. The current Windows build 2.22.0-2, frozen at the 2.22 branch, supplies a stable ABI compatible with GTK 2.22, glibmm, cairomm, and pangomm, enabling compilation with MSVC or MinGW toolchains. Developers should note that, as of January 9 2026, this Windows edition remains several major cycles behind the contemporary Linux counterpart (4.21.2), so new GTK4 features like GL-based rendering, media playback widgets, and layout managers are not yet exposed through the Windows cpp interface. Despite the version gap, gtkmm 2.22.0-2 continues to serve as a dependable GUI framework for cross-platform C++ projects that prioritize long-term API stability over cutting-edge capabilities. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest published build and supporting batch installation alongside other applications.
