This is a C++ based interface designed to work in conjunction with the widely used graphical user interface (GUI) library known as GTK+. It streamlines the process of developing GUI-based software applications using C++.
With gtkmm, you have the option to create user interfaces in either code or through the Glade designer, which can be done using libglademm. It's worth noting that gtkmm is freely available software that's distributed under the GNU Library General Public License (LGPL).
It's important to understand that gtkmm is a GUI toolkit and nothing more. The goal is to be the best C++ toolkit available, so you won't find generic C++ data structures, an XML parser, or database access included in the package. However, gtkmm is designed to work beautifully alongside other C++ libraries.
If you're in need of some additional functionality, the gnomemm libraries are always available for the other tasks. It's worth mentioning, however, that these libraries are optional. Overall, gtkmm is a solid choice for those in search of a reliable and comprehensive C++ GUI toolkit.
