qfiledialog.cpp + CMakeLists.txt

SUMMARY
***
After closing the QFileDialog the program should terminate because QGuiApplication::setQuitOnLastWindowClosed(true) by default. But the program continues to run.
When using QCoreApplication::setAttribute(Qt::AA_DontUseNativeDialogs) (i.e. qt dialogs) the program behaves as expected: it quits if setQuitOnLastWindowClosed(true), it continues if setQuitOnLastWindowClosed(false).
***


STEPS TO REPRODUCE
1. Unzip the attached qfiledialog.zip
2. Build with cmake
3. Run the program

OBSERVED RESULT
After closing the dialog the program continues to run.

EXPECTED RESULT
After closing the dialog the program should terminate.
Native and non-native dialogs should behave consistent.

Comment 1 wolf.seifert 2024-03-24 04:46:00 UTC 
Deleting these lines

    // eventLoopLocker prevents QCoreApplication from exiting when the last
    // window is closed until the job has finished running
    QEventLoopLocker eventLoopLocker;

from kjob_p.h resolved this issue.
