The Tix apps framework http://tix.sourceforge.net/Tixapps/ is a library and suite of programs which work as either Tcl or Tkinter applications.
It includes:
- TixInspect: an inspector for Tix/Tk applications. It uses Tk's send command to retrieve infomation from other Tk applications.
- TixDebug: a debugger to work with tixinspect.
- TixInfo: an info browser for GNU documentation.
- ObjTix and objected oriented wrapper for Tix's OO framework.
Binaries are available for Linux and Windows at http://freshmeat.net/projects/tixapps/
