Hi Alan,
My X system as far as I know has always worked OK, both with plplot and other
programs. On Plplot, X-Window (Xlib) is always the first choice and it has
always worked--X launches and a graphics window appears with the plplot stuff
in it. I can also run the programs you mention, and I have in the past run
Grace and a version of OpenOffice among others. This is the X systems that
Apple ships as part of the developer tools.
Here is what I think I know about Tcl/Tk on OS X. tclsh is available at the
command line. wish is also available and runs with a native ("Aqua") look and
feel. These are installed either out of the box or as part of the developer
tools. wish can be built for X if desired (Wikipedia) but an X version is
apparently not available out of the box. When I type wish in any OS X terminal
or Xterm, the native wish shell launches and can run the widget demos, all of
which work and are rendered in native Aqua.
So the point here is--wish on OS X runs natively, not as an X app.
Typing /usr/local/plplot/bin/plserver causes a native program to run that looks
exactly like wish except the background on the window which displays the list
of demos is gray instead of white, and the program name that is displayed is
"plserver" instead of "Wish".
When I run x01c and choose device Tcl/TK Window, a native program is started
called plserver but looks different--in its own window near the top is a
drop-down menu with items About... and Exit. (Remember that on OS X, the
standard menus are in a menu bar that is fixed at the top of the screen, not
attached to each window.) When About... is chosen, a description of PLplot
appears in a new window. There is another drop-down menu Help with items On
Tcl/Tk, On GUI, and On Keys-- each of these opens a new window with help
information. No plot appears, and as I have described before, when Quitting the
program using the standard menu bar menu, it hangs and has to be force-quit. No
plot ever appears. If I select Exit from the first menu in the window, the menu
turns gray for a few seconds but the program continues to run. Typing exit in
the terminal causes the program to stop running.
