recreating this graphic in Qt

[ken.teh]

I am rewriting a 15 year old program in Qt and would like to recreate and improve on the graphic in the lower half of this picture.

I am new to Qt but have written all of their other panels. The only remaining piece is this graphic.

Can someone suggest which module/set of classes I should read up that is best suited to my task? I've worked through the basic examples of creating custom widgets with QPainter and I think I can wrangle something together that looks and works like the graphic but I'd like to improve on it and want to know where to concentrate my reading.

While the top half looks like custom widgets, I would have thought the bottom diagram might best be a QGraphicsScene with graphics objects on it, which you have not read up on. But I'm not an expert.

It's a job for the QGraphicsView framework, I would say.

Some examples:

• https://doc.qt.io/qt-5/graphicsview.html

• https://doc.qt.io/qt-5/examples-graphicsview.html
  Especially this might be interesting:

@JonB I'm too slow at pasting links and looking for the right example :))

Thank you to those who responded. My Qt version with a QGraphicsScene.
