QApplicationPrivate::focus_widget became a dangling pointer in the following scenario: A widget first gets focus and later on gets a focus proxy. QApplicationPrivate::focus_widget was still pointing to the initial widget. Upon destruction, QWidget::hasFocus() [which follows to the focus proxy and then compares with focus_widget] was therefore false for both widgets. So QWidget::clearFocus() didn't call QApplicationPrivate::setFocusWidget(0) for either of them. As a result, focus_widget remained set, and became dangling. In real life, this happened with a QWebEngineView, which the application gave focus to upon creation. At that time it doesn't have a focus proxy yet. That happens later, in QWebEngineViewPrivate::widgetChanged. https://bugs.kde.org/show_bug.cgi?id=381793 Change-Id: Ifee610bb76a2d4d2797b98ece9bffe5fffe3c6a6 Reviewed-by: Volker Hilsheimer <volker.hilsheimer@qt.io> |
