Q:

Qt link to Ovi(Nokia) Store shop

Is there any way I can let a qml image take users to the pro version if my app in the ovi store client once its clicked? 

A:

The same link as on the Ovi/Nokia Store website should open the store app on the device.  
E.g.
Qt.openUrlExternally("http://store.ovi.com/content/198002")

opens the store app for the "4squick free" app.  Tested on N9 but should also work on Symbian.
