Besides the obvious cases handled in previous commit Change-Id: Ifa84a038fc56f34958cd732caeb9c436b48b3c75 Author: Michael Weghorn <[email protected]> Date: Fri Aug 30 10:12:21 2024 +0200 tdf#162696 qt weld: Do GUI things in main thread , the destruction of `QtInstanceDialog::m_pDialog` (that previously implicitly happened due to it being a `std::unique_ptr`) also needs to happen in the main thread. Otherwise, it triggers this assert with a debug Qt build for the tdf#162696 of installing an extension via drag'n'drop into the start center: ASSERT failure in QCoreApplication::sendEvent: "Cannot send events to objects owned by a different thread.

Instead of deleting the QDialog owned by the QtInstanceDialog in the QtInstanceDialog dtor right away by calling std::unique_ptr<QDialog>::reset, instead mark the object for deletion by calling QObject::deleteLater [1] on the dialog object, which schedules the object for deletion when control returns to the event loop. Also switch QtInstanceDialog::m_pDialog from a unique_ptr to a plain QDialog*. This fixes crashes seen with the current qtbase git dev branch after qtbase commit commit 84a5f50c7766c99f62b22bb4388137e0aa8dd13d Author: Shawn Rutledge <[email protected]> Date: Tue Nov 12 10:04:31 2024 +0100 Move QContextMenuEvent synthesis from QWidgetWindow to QWindow The crash was quite reproducible for me by running LO with the qt6 VCL plugin and SAL_VCL_QT_USE_WELDED_WIDGETS=1 (to enable use of native Qt widgets), opening the "Help" -> "About LibreOfficeDev" dialog and closing it by clicking the "Close" button with the left mouse button.

This is because the QWidgetWindow object and its QWidgetPrivate have already been deleted when processing an earlier event triggered by the mouse click, see backtrace below. Not deleting the object right away but marking it for deletion later makes sure the object is still valid when the event gets processed, and then deleted afterwards. Backtrace of how the QWindowPrivate object got deleted earlier (reverse-debugged with rr) - see frame 17 for the dtor (i.e. the code that was adjusted in this commit now to fix the problem): Thread 1

Instead of deleting the QDialog owned by the QtInstanceDialog in the QtInstanceDialog dtor right away by calling std::unique_ptr<QDialog>::reset, instead mark the object for deletion by calling QObject::deleteLater [1] on the dialog object, which schedules the object for deletion when control returns to the event loop. Also switch QtInstanceDialog::m_pDialog from a unique_ptr to a plain QDialog*. This fixes crashes seen with the current qtbase git dev branch after qtbase commit commit 84a5f50c7766c99f62b22bb4388137e0aa8dd13d Author: Shawn Rutledge <[email protected]> Date: Tue Nov 12 10:04:31 2024 +0100 Move QContextMenuEvent synthesis from QWidgetWindow to QWindow The crash was quite reproducible for me by running LO with the qt6 VCL plugin and SAL_VCL_QT_USE_WELDED_WIDGETS=1 (to enable use of native Qt widgets), opening the "Help" -> "About LibreOfficeDev" dialog and closing it by clicking the "Close" button with the left mouse button.

This is because the QWidgetWindow object and its QWidgetPrivate have already been deleted when processing an earlier event triggered by the mouse click, see backtrace below. Not deleting the object right away but marking it for deletion later makes sure the object is still valid when the event gets processed, and then deleted afterwards. Backtrace of how the QWindowPrivate object got deleted earlier (reverse-debugged with rr) - see frame 17 for the dtor (i.e. the code that was adjusted in this commit now to fix the problem): Thread 1
