wxWidgets Cross-platform C++ GUI toolkit (GTK+ runtime) wxWidgets (formerly known as wxWindows) is a class library for C++ providing GUI components and other facilities on several popular platforms (and some unpopular ones as well). For more information see http://wxwidgets.org This package provides the shared libraries needed to run programs linked against wxWidgets. To use the (optional) glcanvas library you will need to have Mesa or OpenGL installed.
