Hi Steven,

good that it works for you, but it also has it's limitations: It will work e.g. not on Mac when you're creating an app bundle, or when developing for a device where an actual deployment step is involved. It will also not work if your shadow build directory is not exactly one level above.

Actually a somewhat more clean hack that you can use is to hardcode the absolute path. You can achieve this pretty e.g. adding to your .pro file:

DEFINES += QMLDIR=$$PWD/qml

and then use setMainQmlFile(QMLDIR/main.qml)

Anyhow, this doesn't work for deployment to a device either, for obvious reasons ...

Regards

Kai
