[GRASS-dev] tcltk interface

[Benjamin Ducke]

I think he meant X11, not "xterm"?

Several things are getting mixed up here, I am afraid.
The Windows version of Tcl/Tk does not use X11 for display,
the Unix versions do, of course (as far as I understand,
that includes OS X, but I may be wrong here).
XTerm is not capable of rendering graphics. It can only
do text. It's only used to type and run commands.
Many Linux users nowadays don't run XTerm as
their command console anymore, but use one of the more
convenient replacements, such as those that ship with
Gnome or KDE. Mac OS X has its own console application.
You can run the d.* modules from an XTerm, but they
will then open an X11 window to render the graphics on.
Thus, they are not really portable to Windows, unless
you install and run an X11 for Windows (such as via Cygwin).
The Tcl/Tk digitizer uses it's own TclTk canvas for graphics, 
so will work fine on Windows.

Sorry if this all sounds like a lecture in "Unix A", but
Rashad, if you want help from this list, you need to get
your concepts and terms straight. GRASS comes from the
Unix world, so it carries all these Unix ideas and technologies
with it. I hope my explanations have helped clarifying things
a bit.
