      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 }
              }
          }
      }
