Re: [Plplot-devel] runAllDemos.tcl background colour issue under wish

[Alan W. I. <ir...@be...>]

Thanks, Vince!  Without those checkin's I got a change to grey (but not black)
background.  With those checkin's the problem was solved (i.e. black
background at last!)

Here is the cookbook that results in a black background now:

wish
% source pldefaults.tcl
% load libplplotd.so Plplotter
% package provide Plplotter 5.1.0
% source runAllDemos.tcl

N.B. it is essential that source pldefaults.tcl occurs first in this
sequence. Otherwise, I get the beige background.

From my previous tests the command pldefaults is just not defined at the
time you execute it in plplot.tcl so I changed that (locally) to source
pldefaults.tcl.  However, that gives the beige background result (without
any error messages), and in fact source pldefaults.tcl interactively on the
wish command line as above no longer works if you make that change to
plplot.tcl.  So invoking source pldefaults.tcl from plplot.tcl seems to be
equivalent to invoking it on the wish command line above after the load and
with the same beige result.  So far, the only thing that works is to have
the source before the load with no source pldefaults.tcl afterward (on the
command line or in plplot.tcl).

So I suggest you look carefully at the order in which source pldefaults.tcl
is invoked for plserver, and copy that for the present case (assuming it
works for you as well.)
