string does not implement core.QBitArray_ITF (missing QBitArray_PTR method) #823

While running qtsetup against Qt 5.13.0, I've hit another compilation error:

github.com/therecipe/qt/internal/examples/qml/gallery
# github.com/therecipe/qt/internal/examples/qml/gallery
./gallery.go:25:48: cannot use style (type string) as type core.QBitArray_ITF in argument to core.NewQVariant14:

Can confirm that downgrading to 5.12.2 solves this issue. You'll probably need to release a fix once the final stable 5.13.0 arrives.

Hey

Yes, there seems to be some api breakage coming with 5.13. I will update the examples once 5.13 is released, in the meantime you could use QT_API=5.12.0 to link against Qt 5.13 while using the 5.12 api used in these examples.

I also plan to create core.NewQVariant1, which will accept ...interface{} to work around this issue in the future.
