Hi,
using the pgbegin and the PGPLOT module, the pop up does not show.
So is the code using the grwnd in the similar PDL module to trig
that?

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
