The code snippet in he PathLine documentation doesn't work as it is.

doc link : https://doc.qt.io/QtForMCUs-2.4/qml-qtquick-pathline.html

This documentation has a code snippet below:

Path {
    startX: 0; startY: 100
    PathLine { x: 200; y: 100 }
} 

But since it uses Path, which is invisible, if the reader copies and pastes it to their Qt Creator and runs the app, it won't show anything.

To avoid this confusion and possible frustration, I'd like to suggest replacing the current snippet with this one, with a note that the readers must link Qul::Shapes to their project to import QtQuick.Shapes.

import QtQuick 2.0
import QtQuick.Shapes
Rectangle {
    width: 300
    height: 300
    Shape {
        ShapePath {
            strokeColor: "black"
            startX: 0; startY: 100
            PathLine { x: 200; y: 100 }
        }
    }
} 

The code above outputs this:
