The GNUstep gui Library is a powerful library of graphical user
interface classes written completely in the Objective-C language;
the classes are based upon the OpenStep specification, and provide
the user with a traditional nextstep-like look and feel. The
classes include graphical objects such as windows, menus, buttons,
text fields, popup lists, browsers, scrollviews, splitviews, fonts,
colors, images, events, pasteboards,... This package includes
development headers too. You need the corresponding backend
library package (gnustep-back) to use this package.
