    }
}

And here my warning :
file:///home/ellypsis/dev/linux_phone/ut_app/Mines/build/tmp/qml/Main.qml:210:13: QML Grid: Cannot specify anchors for items inside Grid. Grid will not function.
But in fact, the code functions pretty well. But it's not a reason to let a warning in the code.
Any idea?
