Hi, I'm currently implementing a QPA plugin for Qt-4.8.4. What I now see is a crash (ASSERT) in QWidget::effectiveWinId() as nativeParentWidget() returns 0. This is happening when I send mouse move events to Qt and the cursors leaves a widget:
#5 0x00007ffff6541555 in qt_assert (assertion=0x7ffff789f049 "realParent", file= 0x7ffff789ee50 "kernel/qwidget.cpp", line=2620) at global/qglobal.cpp:1996 #6 0x00007ffff70f63f7 in QWidget::effectiveWinId (this=0x674f20) at kernel/qwidget.cpp:2620 #7 0x00007ffff7138767 in qt_qpa_set_cursor (w=0x674f20, force=false) at kernel/qwidget_qpa.cpp:865 #8 0x00007ffff713623b in QWidgetPrivate::unsetCursor_sys (this=0x6753c0) at kernel/qwidget_qpa.cpp:258 #9 0x00007ffff70fb337 in QWidget::unsetCursor (this=0x674f20) at kernel/qwidget.cpp:5115 #10 0x00007ffff75fb56e in QToolBar::event (this=0x674f20, event=0x7fffffffcb10) at widgets/qtoolbar.cpp:1183 It's not clear to me if I'm doing something wrong or if it's a bug in Qt. What do I need to do in my QPA plugin so that a widgets has a nativeParentWidget() ? -- Best regards/Schöne Grüße Martin A: Because it breaks the logical sequence of discussion Q: Why is top posting bad?
