The main reason I started the project some years ago, was because I wanted a solid portable widget for a GUI for bigloo. In the process I switched to PLT Scheme, mainly because it implements the R5RS standard much better and macro support is fabulous. I did look a littlebit to MrEd. Not in depth however. I still wanted a solid widget base that is constantly under development and that is portable enough for Windows/Linux/UNIX/Mac OS. Gtk provided me with what I wanted, so I went with that. The binding code for MzGtk2 is also based on ROOS, an OO system that is very similar to perl's OO system. I always liked perl's OO system for its simplicity. --Hans Chongkai Zhu schreef: <blockquote cite="mid000c01c731b2$d6f88760$25e8619b@DrMathematica" type="cite"> <pre wrap="">Hi Hans, Would you please discuss the difference between MzGtk2 and MrEd (and any other GUI toolkits for MzScheme)?

You should be able to compile mzgtk2 for Gtk+ 2.4.x and up. Changes: Added support for PLT Scheme threads in the MzGtk2 distribution. What MzGtk2 does is install a timer function in the event loop of Gtk+-2.x which runs about every millisecond. This function calls scheme_use_fuel() to give PLT Scheme the oppertunity to run threads.
