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

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

Vince,

BTW since you made some changes during the night, I have rebuilt plplot from
scratch.  However, everything works identically (as far as I can see) to
before including the background colour problem.

When wish and plserver are first started a tiny GUI comes up that is
essentially completely blank and beige-coloured in my case.  I think that in
both cases it is picking up the default GUI background colour from my KDE
environment.  However, once you source runAllDemos.tcl, then the background
in the plotting area for plserver is black (just as in the standalone demos)
while for wish it continues to be beige.  So somehow the plplot default
background of black is not overriding the wish default background of beige.
I can send you some ugly (;-)) screenshots of this, but probably the word
picture is enough.

You may have the same thing, but may not recognize it if you are starting
with a default wish background of black.  Start wish with some other default
background colour to see if plplot can override it.  If you do get a change
in background colour from when wish starts to when you source
runAllDemos.tcl, then perhaps the #ifed windows version of the plplot code
is handling the background colour in a different way?
