[MACTCL] under OSX, including tests of widget demo

[Franc B. <br...@cb...>]

Jim,

Last month you kindly instructed us how to install latest version of tk
under OSX. It turned out that our tcltk application (already crossplatform,
including under macOS9.2) is too complex for a quick fix under OSX -- it
requires augmenting the "standard mac OS9.x" distribution with packages
such as latest tcllib, tclxml, BWidget, TclSOAP, TclDOM. Some missing
features are also listed under our "widget test" below.

Soon afterwards, I left for Europe with the Titanium, resigned to demo
under OS9.2 -- only to find out in the last moment that Titanimum would
synchronize with the projector under OSX only -- so while I could still
project PowerPoint under OSX, I could not do the same for the tcltk
application.

We are trying to figure out what chances we have for a "quick"
cross-plaform tcltk port to OSX. We have a number of concerns:

(1) the structure of current tcltk-installed directory has no resemblance
to 9.2 and earlier generation. Even the nominal "widget test" directory
appears to be missing. The 9.2 structure makes the "nominal mac
distribution" easier to augment with missing parts from a standard linux
distribution. How are we to proceed with augmenting the "standard OSX
distribution".

(2) can we hope for a quick fix to the current version of wish-OSX, so that
the entire widget directory works as in the earlier versions .... I have
results from my tests below -- it appears that fixing the "stdout" channel
problem would fix a number of related problems ..... this is my entire
problem list:

   labels #8
       no images are displayed

   menus #2 (menu buttons)
   bgerror failed to handle background error.
       Original error: can not find channel named "stdout"
       Error in bgerror: invalid command name "sting"

   misc #2, #3 (both grab commands)
   bgerror failed to handle background error.
       Original error: can not find channel named "stdout"
       Error in bgerror: invalid command name "sting"

Any comments and suggestions on these experiences would be most appreciated.

MANY THANKS -- Franc Brglez
