Bug ID: 503838
Summary: Not emitting KNotification::closed on timeout with
KNotification::CloseOnTimeout flag OR need a way to
dismiss a notification and keep it in history
Classification: Frameworks and Libraries
Product: frameworks-knotifications
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kdelibs-b...@kde.org
Reporter: noaha...@gmail.com
CC: kdelibs-b...@kde.org
Target Milestone: ---
SUMMARY
I'm pretty sure KNotification::closed should be emitted when a notification
times out with the KNotification::CloseOnTimeout flag. However, I also noticed
that calling KNotification::close removes a notification from notification
history, which is not something I want for my usecase. I'm not sure if there's
a bug or if this needs to be a feature request. Spectacle needs a way to let a
notification with a URL pointing to a file remain on the screen before it has
expired and in history without keeping Spectacle alive.
STEPS TO REPRODUCE
1. Create a KNotification object with the KNotification::CloseOnTimeout flag.
2. Send the notification while the GUI isn't visible and a QEventLoopLocker is
active to keep the application alive.
3. Connect KNotification::closed to a lambda that deletes the event loop locker
when the notification is closed.
OBSERVED RESULT
The notification appears, expires and is sent to history, but
KNotification::closed is never emitted. If I use a QTimer to call
KNotification::close, the notification disappears from notification history,
which is undesirable for my usecase.
EXPECTED RESULT
It should be possible to separate the notification being visible on the screen
or in history from the lifetime of the sending app.
