What is .QML file?
A QML file will always start with at least one import statement (since QML does not import any modules by default an import statement is necessary, or else no elements will be available). Here is a basic example of a QML file:
import QtQuick 1.0
width: 120; height: 160;
text: modelData.firstName + " " + modelData.lastName
