GUI: PLT Graphics Toolkit

Matthew Flatt,
Robert Bruce Findler,
and John Clements

This reference manual describes the GUI toolbox that is part of PLT Scheme and whose core is implemented by the MrEd executable.

 (require scheme/gui/base)

The scheme/gui/base library provides all of the class, interface, and procedure bindings defined in this manual. At run time, this library needs primitive graphics support that the MrEd executable provides; this library cannot run in MzScheme.

 #lang scheme/gui

The scheme/gui language combines all bindings of the scheme language and the scheme/gui/base modules.
