The widget test is still there.  For instance, just start up the Wish
Shell.app, and do:

source [file join $tk_library demos widget]

What used to be in the Tool Command Language folder on Classic MacOS is now
in the Resources/Scripts folder in each of the frameworks.

This is probably just because you aren't setting up the paths for the widget
demo correctly.  If you use the one that is part of the Tk framework, as
shown above, I bet this will work fine.

This was a bug that is fixed in the current sources in the macosx-8-4-branch
version of Tk.  It is pretty easy to build this, there are instructions in
the announcement I sent with the first binary.

For other packages, you have two problems, building the ones that need
building, and getting Tcl to find them...  Building the Tcl only ones that
you mentioned is not too hard, it is easier if you build Tcl, and then point
the new packages at the tclConfig.sh in the framework.  Most of the
extension configury prefers the build version of Tcl to the installed, and
will find all the things they need.

On getting Tcl to find them.  I need to work out how I want to seed the
tcl_pkgPath, and the auto_path, for Tcl on MacOS X.  I was struggling just
to get it to find the Framework versions of packages at first.  This works
now, and so the next step is to seed the pkg path both with the typical
Unix'y places to find stuff, and somewhere in ~/Library, /Library, and
/System/Library.  For now, you can just seed it  yourself with wherever you
are putting stuff.  One thing that would work for a stand-alone app is to
put tcllib, etc in the Resources/Scripts folder of your App package.  This
gets added to the auto_path by default, so packages here should get found
automatically...

Hope this helps,

Jim
