How to draw a large number of interactive elements in Qt?

Question

Qt

Good day to all!
There is the following situation: there is a channel handler module, which receives 10,000 threads as input. You need to visualize them somehow. That is, there should be some kind of "tablet" consisting of small squares (for example, 100 pieces per line), and having a color (green / red) and text. At the same time, it should be possible to display a dialog box by clicking on one of these squares. How to implement it in the most "beautiful" way in terms of implementation and less resource-intensive?

Answer 1

Looked towards QGraphicsScene/QGraphicsView for squares?
