libyui-qt seg fault and doubt

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi I found this code: // Ugly hack as a workaround of bug #121872 (Segfault at program exit // if no Qt style defined): // // Qt does not seem to be designed for use in plugin libs. It loads some // add-on libs dynamically with dlopen() and unloads them at program exit // (QGPluginManager). Unfortunately, since they all depend on the Qt master // lib (libqt-mt) themselves, when they are unloading the last call to // dlclose() for them causes the last reference to libqt-mt to vanish as // well. Since libqt-mt is already in the process of destruction there is // no more reference from the caller of libqt-mt, and the GLIBC decides // that libqt-mt is not needed any more (zero references) and unmaps // libqt-mt. When the static destructor of libqt-mt that triggered the // cleanup in QGPluginManager returns, the code it is to return to is // already unmapped, causing a segfault. // // Workaround: Keep one more reference to libqt-mt open - dlopen() it here // and make sure there is no corresponding dlclose(). QString qt_lib_name = QString( QTLIBDIR "/libQtGui.so.%1" ).arg( QT_VERSION >> 16 );; But it does nothing, since QTLIBDIR and i suspect also QT_LOCALEDIR are not set. Then i've realized that libQtGui in qt5 is called libQt5Gui but even forcing the right name and path it segfault anyway. But maybe you that added this code know what means and how to eventually fix.

YDateField and YTimeField issues
by Angelo Naselli 19 Feb '14

19 Feb '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi I understand that they are "optional", but i think they are important. So to summarize i found: 1) ncurses does not implement them at all :( 2) gtk YTimeField does not manage seconds 3) gtk YTimeField allows 99:99 (and sets value accordingly) 4) gtk YDateField allows 9999-99-99 (and sets value accordingly) 5) QT YDateField does not send any events on date change 6) QT YTimeField does not send any events on time change They should work the same shouldn't they? I believe point 2 to 6 are not so hard to fix, while 1 is, at least for me. Could someone with ncurses skill add at least something like an NCInputFIeld, maybe with some checks on setValue? Since the default view for calendar is something like YYYY-MM-DD also for qt and gtk i don't think it's that wrong after all no? WDYT?
