hi, not sure, if i am doing something completely wrong here. i'm using a QMainWindow with a QQuickView as central widget. the application does not make use of QApplication::exec, but i'm polling the event loop manually from the application.
however the application deadlock on exit, when i'm deleting the QApplication: > * thread #1: tid = 0x4164ee, 0x00007fff8ffd5716 > libsystem_kernel.dylib`__psynch_cvwait + 10, queue = 'com.apple.main-thread, > stop reason = signal SIGSTOP > frame #0: 0x00007fff8ffd5716 libsystem_kernel.dylib`__psynch_cvwait + 10 > frame #1: 0x00007fff95ae4c3b libsystem_pthread.dylib`_pthread_cond_wait + > 727 > frame #2: 0x0000000101e19511 QtCore`QWaitConditionPrivate::wait(unsigned > long) + 49 > frame #3: 0x0000000101e193ca QtCore`QWaitCondition::wait(QMutex*, > unsigned long) + 170 > frame #4: 0x000000010118fb44 QtQml`QQmlThread::shutdown() + 116 > frame #5: 0x0000000101122e8f QtQml`QQmlTypeLoader::~QQmlTypeLoader() + 31 > frame #6: 0x00000001010c4b8a > QtQml`QQmlEnginePrivate::~QQmlEnginePrivate() + 1946 > frame #7: 0x00000001010c43ce > QtQml`QQmlEnginePrivate::~QQmlEnginePrivate() + 14 > frame #8: 0x0000000102029334 QtCore`QObject::~QObject() + 1748 > frame #9: 0x00000001010c68b2 QtQml`QQmlEngine::~QQmlEngine() + 386 > frame #10: 0x00000001010c670e QtQml`QQmlEngine::~QQmlEngine() + 14 > frame #11: 0x000000010202950e QtCore`QObjectPrivate::deleteChildren() + > 110 > frame #12: 0x0000000102029314 QtCore`QObject::~QObject() + 1716 > frame #13: 0x00000001006f9a7c QtGui`QWindow::~QWindow() + 140 > frame #14: 0x0000000101506f67 QtQuick`QQuickView::~QQuickView() + 151 > frame #15: 0x0000000101506e7e QtQuick`QQuickView::~QQuickView() + 14 > frame #16: 0x000000010202950e QtCore`QObjectPrivate::deleteChildren() + > 110 > frame #17: 0x0000000102029314 QtCore`QObject::~QObject() + 1716 > frame #18: 0x00000001006f9a7c QtGui`QWindow::~QWindow() + 140 > frame #19: 0x000000010181b51b QtWidgets`QWidgetWindow::~QWidgetWindow() + > 139 > frame #20: 0x000000010181b43e QtWidgets`QWidgetWindow::~QWidgetWindow() + > 14 > frame #21: 0x0000000101818cd3 > QtWidgets`QWidgetPrivate::deleteTLSysExtra() + 83 > frame #22: 0x0000000101818b28 QtWidgets`QWidget::destroy(bool, bool) + 888 > frame #23: 0x00000001017c25fe QtWidgets`QApplication::~QApplication() + > 270 > frame #24: 0x00000001017c24ce QtWidgets`QApplication::~QApplication() + 14 there seems to be one other qt-related thread: > * thread #6: tid = 0x416536, 0x00007fff8ffd59aa > libsystem_kernel.dylib`select$DARWIN_EXTSN + 10, name = 'QThread > frame #0: 0x00007fff8ffd59aa libsystem_kernel.dylib`select$DARWIN_EXTSN + > 10 > frame #1: 0x000000010204e213 QtCore`qt_safe_select(int, fd_set*, fd_set*, > fd_set*, timespec const*) + 547 > frame #2: 0x000000010204ef58 > QtCore`QEventDispatcherUNIXPrivate::doSelect(QFlags<QEventLoop::ProcessEventsFlag>, > timespec*) + 680 > frame #3: 0x000000010204fdca > QtCore`QEventDispatcherUNIX::processEvents(QFlags<QEventLoop::ProcessEventsFlag>) > + 250 > frame #4: 0x0000000101ffd05d > QtCore`QEventLoop::exec(QFlags<QEventLoop::ProcessEventsFlag>) + 397 > frame #5: 0x0000000101e140e3 QtCore`QThread::exec() + 115 > frame #6: 0x0000000101e17e60 QtCore`QThreadPrivate::start(void*) + 352 > frame #7: 0x00007fff95ae2899 libsystem_pthread.dylib`_pthread_body + 138 > frame #8: 0x00007fff95ae272a libsystem_pthread.dylib`_pthread_start + 137 > frame #9: 0x00007fff95ae6fc9 libsystem_pthread.dylib`thread_start + 13 platform is osx 10.9, qt-5.2. any idea, how to further debug this issue? thanks in advance, tim _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
