[Qgis-developer] [Qgis-user] Reading Qsettings outside QGis

[PIERRE Sylvain]

Unfortunatly, it's not working. I forgot to comment old line wich was:

        settings = QSettings("HKEY_USERS\\S-1-5-21-135220595-821698489-1543119021-16853\\Software\\QuantumGIS\\QGIS",QSettings.NativeFormat)
and is working, but it's not a permanent solution.
The last one I mentioned is not working:
        settings = QSettings( QSettings.NativeFormat, QSettings.UserScope, 'QuantumGIS', 'QGis')
I use InitQGis in my app, but  QSettings() return nothing, so maybe here's a bug...

Thanks for interest!

You  are right. With no args QSettings outside Qgis return nothing. After consultinq Qt doc and with your help, this code is working:

QSettings( QSettings.NativeFormat, QSettings.UserScope, 'QuantumGIS', 'QGis')

Diving into Python, Qt and Pyqgis since few months, I have new questions each day, and each day, I find answers...

Great job made by all developpment teams and plugins developpers , where I can find lots of code.

Hi Pierre,

yes this is the right approach.  However, you must make sure that the proper organisation (QuantumGIS) and application (QGIS) are set.  Your problem is probably because the QSettings is initialized with some default values.

This is done automatically when using plugins in the qgis app, but not if your are creating an external app.

Although it should happen when calling QgsApplication.initQgis() - you might want to file a bug report for that.

BTW - you might get more feedback if posting to the qgis-devel mailing list.
