QgsMessageLog.logMessage: argument notifyUser doesn't change anything

[pers-ephone]

What is the bug or the crash?

A call to QgsMessageLog.logMessage with notifyUser=True seem to be the same as with notifyUser=False whatever the level.

The doc states "If notifyUser is True, then the message should be brought to the user’s attention by various UI hints.", one would expect a call to the message bar, a forced opening of the message log window, or other direct and systematic communication to the user. For now as a plugin dev i have to consider this argument as always false and manage all communication to the user.

The argument seem to only allow this messageReceived signal to be sent and not in the case of an INFO message. So info messages fully ignore the argument, and otherwise i don't know what uses the signal but i see no difference in use.

Steps to reproduce the issue

in python console: QgsMessageLog.logMessage("test", "tab", Qgis.Warning, False) QgsMessageLog.logMessage("test", "tab", Qgis.Warning, True)

QgsMessageLog.logMessage("test", "tab", Qgis.Info, False) QgsMessageLog.logMessage("test", "tab", Qgis.Info, True)

QgsMessageLog.logMessage("test", "tab", Qgis.Critical, False) QgsMessageLog.logMessage("test", "tab", Qgis.Critical, True)

@pers-ephone, QGIS 3.28 is no longer supported. Anyway, it seem to me there is a UI hint using QGIS 3.34:

notifyUser=False

notifyUser=True

@agiudiceandrea Ok i was wrong this is just very very subtle if not looking for it. One question still stands, why do log messages with level=Qgis.Info never notify the user, ignoring the notifyUser argument?

It looks like by design: https://github.com/qgis/QGIS/blob/69f3a387f7ca18371029aa970fdb54d9692ac88a/src/core/qgsmessagelog.cpp#L49-L52
