[Interest] Multiple rectangles or any shapes in Scene Graph plugin?

[Mark]

Hi,

Another day, another Scene Graph question.

In plain QML it's very easy to make a few rectangles laying on top of
each other. I'm having trouble doing the same thing in a Scene Graph
QML Component plugin (updatePaintNode specifically).

What i want to do is draw a few shapes. One is a plain simple
rectangle where i want to draw multiple lines (to make a grid). each
line is probably it's own QSGGeometry::Point2D so there is issue one.
How can i have multiple lines?

Even if i get that done, i still want to put another "layer" on top of
that grid to display something. Like a line graph/chart.

Or is the right approach to think very abstract here and have - lets
say - 3 different custom components.
1. background
2. grid
3. custom shape on top of grid

If that's the case then i'd still like to know how i can draw multiple
lines from within updatePaintNode :)

In QML that would look like this:

CustomRectangle {
  width: 200
  height: 200
  CustomGrid {
    anchors.fill: parent
  }
  CustomShape {
    anchors.fill: parent
  }
}

Note: in case you're wondering. The result i'm trying to get is
somewhat like this [1] only with settable colors.

Regards,
Mark
