Window Maker's own widget set
WINGs Is Not GNUstep (WINGs) is a small widget set with the NeXTSTEP
look and feel. Its API is inspired in OpenSTEP and its
implementation borrows some ideas from Tk. It has a reasonable set of
widgets, sufficient for building small applications like a CDPlayer
or hacking something like rxvt. It is used for basic widgets in
the WindowMaker window manager.
