[SailfishDevel] Alpha 2: passing simple properties from

[christopher.lamb at thurweb.ch]

@Mario

yes BB10 seems to have a setContextProperty (I found this while  
googling for a Sailfish solution).

@Martin

I tried your suggestion before posting my question:

QScopedPointer<QQuickView> view(Sailfish::createView("main.qml"));
view->rootContext()->setContextProperty("platform", platformId);

While my code compiles, when I try and use the property platform in my  
QML I get errors:

file:///opt/sdk/landedsettingsQt5_21/usr/share/landedsettingsQt5_21/main.qml:34: ReferenceError: platform is not  
defined
