Description:

The Xfce Foundation Classes is a set of integrated C++ classes
for developing Xfce applications on UNIX-like operating systems
such as Linux. The classes combine the power of GTK+ and the power
of C++ into a state-of-the-art application development framework
for the Xfce Desktop Environment. The classes judiciously use C++
language features to avoid layering on too much extra C++ complexity.
The API is easy to understand and use, and should feel immediately
familiar to most GTK+ programmers. The Xfce Foundation Classes is part
of the Xfce project, and like Xfce it's lightweight, fast and easy to use.
