[Plplot-devel] RE : RE : Qt driver update
Werner, Good news for the flush() issue. It works on Windows too (I just had forgotten to save the changes I told you to do). To bring the window to front, try to add widget-raise() after widget-flush() in plD_eop_qtwidget.

Hi Alban, this works as well. Very good, so apart from this color issue, the qt drivers on Mac work quite well. I'll commit this as well. Please test on Linux if these changes did mess something up.

Re: [Plplot-devel] RE : RE : Qt driver update
Hi Alban, yes this works. I'll commit this as well. We may have to discuss, if this doesn't break anything else, e.g. if someone wants to use the driver in her Qt application, but as I understand it will initQtApp() only called if there is no existing qt app (or at least the specific lines), so this should be not much trouble.

Irwin Cc : Plplot-devel mailing list; Hazen Babcock Objet : Re: [Plplot-devel] Qt driver update Hi, I think I found out what the problem is. The first page reads okay, but then qt takes over to show the plot and somehow changes the locale or something. This is on a Mac, English version, but Austrian locale - so after that scanf expects floating point numbers to be written numbers like 3,1415 and not 3.1415. scanf fails then on the numbers. I assume that this is the problem, since I printed the out the numbers with printf in case sscanf fails and the output is: 0: 0.0 0.0 0.0 0.0 1.0 0 1: 1.0 1.0 1.0 1.0 1.0 0 0: 0.0 1.0 1.0 1.0 1.0 0 0,00, -0,00, 0,00. 0,00, 0,00, 3075440 *** PLPLOT WARNING *** Unrecognized cmap1 format (wrong number of items (1) for version 2 of format) 0.0 1.0 1.0 1.0 1.0 0 I'll try now to play around with my locale. The other Mac has also Austrian locale, but obviously Qt cocoa doesn't mess around here. Ok, this is the problem. Qt carbon changes the locale and sscanf doesn't work as expected any more. If I add setlocale(LC_NUMERIC, C); just before the sscanf call, everything works as expected. This is obviously not the correct solution but at least we know what is going wrong. Also if I change my locale to UK the example works as expected.

Re: [Plplot-devel] RE : RE : Qt driver update
On 2009-09-01 12:08+0200 Werner Smekal wrote: Hi Alban, yes this [setting locale in qt] works. Hi Werner: Thanks very much for thinking of locale as a possibility for messing up sscanf. That was a stroke of debugging genius, and it is wonderful news that we now have the reason for all the strange results you were getting when attempting to read palette files. However, I don't think the current solution (revision 10363) to this problem is correct. Instead of forcing the C locale whenever we use qt, the user should be allowed to use any locale they like for _user_ input to PLplot regardless of device driver. Of course, our palette files absolutely require setlocale(LC_NUMERIC, C); in order to be read properly as you have discovered. Thus, I think our best solution to this whole issue is to save the user locale, use setlocale(LC_NUMERIC, C); to read the file, then restore the user locale in both cmap0_palette_read and plspal1. This method absolutely guards against any locale issue (say for a different library than qt) ever again screwing up palette file reading so this is what I like. What do you think of this idea? If you agree, would you be willing to help with the implementation and testing? (I don't know how to get the current locale [there appears to be no function called getlocale, although localeconv might be a possibility on Linux], and we have to insure that setlocale [and whatever you recommend for getting the current locale information] works on all our platforms.)

Hi Alban,
yes, that makes example 17 update regularily. The window opens still
in the background but stuff is plotted without getting the focus. The
other examples still remain grey. Would a
QApplication::processEvents();-call for eop/end help? I didn't find
the corresponding functions in the qt driver, so I couldn't try.
Thanks,
Werner

Hello Werner,
For your issue with example 17, can you try changing
QtPLWidget::flush() in bindings/qt_gui/plqt.cpp (line 594) into:
void QtPLWidget::flush()
{
repaint();
QApplication::processEvents();
}
I hope this will help...

Hi Alban,
I have committed your patch as revision 10346. I am really happy to
see
this go in before our release.
I tried the latest plplot code from svn with Qt 4.5.1 on Mac Os X and
the issues still remain:
* if I start an example (qtwidget device) from the terminal a window
pops up in the background which is just grey. After I click on it, the
plot updates.
* example 17 doesn't update even if it gets the focus. Instead it
remains grey and after some time I'll get only the last plot of
example 17
* example 16 has wrong colors. The following warning messages are
print to the screen:
*** PLPLOT WARNING ***
Unrecognized cmap1 format 0.0 1.0 1.0 1.0 1.0 0
