Hi all,

I just had a look at test.c with wxWidgets, and the problem is, that in plD_tidy_wxwidgets() (which is called before a new init() call) the function wxUnitialize is called - wxWidgets functions shouldn't be called then anymore. I can make it work, if I remove the wxUnitialize call, but then the library won't exit cleanly.

I'll have a look how this can be solved.

Regards,
Werner

I just checked the behaviour with the xwin, tk, xcairo, unpatched
wxwidgets, and qtwidget devices for a multi-paged plot (x02c). For
all of them, hitting the enter key advances to the next page or
cleanly exits the plot for the last page. For all of them (except for
qtwidget, see aside below) right clicking has the same behaviour as
hitting the enter key.

Therefore, hitting the enter key or right clicking the mouse with the
current unpatched wxwidgets device driver with a multi-paged plot does
the right thing so please don't change that behaviour with your patch.

<aside> For qtwidget there appears to be a bug with right clicking on
the first page. It does momentarily move the display to the second page, but
then
it immediately exits. I just now tried some quick experiments with
the bindings/qt_gui/plqt.cpp code, but could not find a fix for this
bug. So I am out of ideas, but I hope someone else with more knowledge
of Qt4 figures this out since our qt device driver has an excellent
reputation which we would like to continue to maintain.
</aside>
