Hi @JKSH,
I know about the proxy settings of the MaintenanceTool.exe but did not find any possibility for setting a proxy in the QtSdkRepoChooser.exe tool :-(
Anyway, thanks for the tip with the Interest mailing list. I will try there.
Ciao Wolfgang

Finally I gave a shot to https://qt.gitorious.org/qt-labs/qml-object-model
It works fine, just needed to reimplement setRoleNames (deprecated in qt5)
Thanks again to the community :D

Great !

You can do that, just update the title prepending [solved] :)
