Summary: Newly added QMessageBox MessageDialog backend returns
wrong result on `exec`
Classification: Plasma
Product: plasma-integration
Version First master
Reported In:
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]

Created attachment 192677
--> https://bugs.kde.org/attachment.cgi?id=192677&action=edit
a minimal example to reproduce the issue
DESCRIPTION
The newly added MessageDialog on plasma integration (
https://invent.kde.org/plasma/plasma-integration/-/merge_requests/204 ) is not
returning the expected result when an app creates a `QMessageBox` with specific
standard buttons and calls `exec` on it
STEPS TO REPRODUCE
See attached main.cpp file for a minimal example
OBSERVED RESULT
The example logs `Value: 1 Flag: QFlags<QMessageBox::StandardButton>()` if you
click "Yes" on the dialog
EXPECTED RESULT
It should log `Value: 16384 Flag: QFlags<QMessageBox::StandardButton>(Yes)`
after clicking "Yes"
SOFTWARE/OS VERSIONS
Operating System: Arch Linux
KDE Plasma Version: 6.7.80
KDE Frameworks Version: 6.27.0

Graphics Platform: Wayland
Processors: 12 × AMD Ryzen 5 4600G with Radeon Graphics

ADDITIONAL INFORMATION
This broke PrismLauncher (a popular Qt based minecraft launcher) since it calls
QMessageBox with `QMessageBox::Yes | QMessageBox::No` standard buttons and then
expects `exec` to return `QMessageBox::Yes` when accepted
