gtkmm (previously known as Gtk--) is the official C++ interface for the popular GUI library GTK+. Highlights include typesafe callbacks, widgets extensible via inheritance and a comprehensive set of widget classes that can be freely combined to quickly create complex user interfaces. Here's an overview, with documentation and status. gtkmm is free software distributed under the GNU Library General Public License (LGPL). Aside from the C++ interface to Gtk 2.x, this package also provides bindings for glib, atk and pango (all of them related with the toolkit).
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
