But I don't know what the (missing) code would look like. It probably
just re-invents what PDL::Graphics::PGPLOT does, anyway.
I'll see if I can come up with something.
You know that you can drag that pop-up wherever you want ? (It's still
annoying, though.)
Maybe we could try contacting the author of the
grwin driver to see if he has a suggestion.
If he's still alive ... it has been around for a while and, no doubt,
modified by a number of individuals over the years ;-)
There's so much kludginess and arcananess surrounding grwnd.exe that it's
hard to know where to start.
Crappy Situation 1
A perl script cannot open a 2nd instance of grwnd.exe, even if the first
grwnd.exe has been closed. (I don't know if this extends across to C
programs.)
Crappy Situation 2
The x86 grwnd.exe (that I've distributed with the PGPLOT ppm package)
produces a pop-up that gives you no other option than to close the grwnd.exe
window.
The x64 grwnd.exe produces a pop-up that gives you a second option - namely
to keep the graphics window open (for re-use) and continue on.
Given the existence of Crappy Situation 1, it's probably crucial that this
second option (provided by the X64 pop-up) exists.
Crappy Situation 3
There's an END{} block in PDL/Graphics/PGPLOT.pm that wants to clean up the
existing grwnd.exe window. Firstly, it throws up the pop-up wanting to know
whether to close the grwnd.exe window. That's probably fair enough - you
might want to exit the script but keep the graphics window open so you can
have a good look at it at your leisure. With x64, at least, you have the
option of doing just that, but again you're confronted with Crappy Situation
2 if you're using x86.
Crappy Situation 4
I thought it might be interesting to see what happens if that END{} block
was commented out - expecting that the script would exit and the grwnd.exe
window would remain open.
Not so - the END{} block aparently serves no purpose on Windows. The
clean-up procedure still throws up the very same pop-up box that would have
been thrown up if the END{} block had *not* been removed.
OTOH, pgplot seems pretty good when it comes to writing to files. No pop-ups
to bother about !!
I think I should be able to find (and then distribute) an x86 grwnd.exe that
throws up the same pop-up as the x64 version does. That will at least reduce
some of the crappiness.
Cheers,
Rob
