If I understood correctly, you want to draw a red line.
The purpose of Path is to position elements through a path. Think of a row or a column that's not straight. You can understand better if you run the first example from this tutorial.

To draw paths you need Shape.

import QtQuick 2.15
import QtQuick.Window 2.15
import QtQuick.Shapes 1.12

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Редактор персонажей")

    Shape {
        ShapePath {
            strokeColor: "red"; // it works :)
            startX: 0; startY: 100
            PathLine { x: 640; y: 480 }
        }
    }
}
