Hi! Like in the title I want to know how to make some sort of minimap.
The basic concept is that I want to show an image from file and drawn rectangles on it.
Also, I want to make interactions with some of this rectangles.

Hi and welcome to devnet,

What kind of file are you talking about ?
What are you using to show it ?

By "file" I mean png or img file.
This is what I want to accomplish:

So have two views, one of the full image and another one like a thumbnail with additional data on it ?

Basically something like that. But how to make interactions when clicking on a specific rectangle?

What should happen when you click on them ?

Idk. This could be anything for now... like calling a defined function or something.

The Graphics View framework might be an interesting start.

@SGaist
You can do this using a custom plain QWidget which for which you can override the paint function and get all the mouse events you require.
As @SGaist suggests the Graphics View Framework is certainly worth looking at.
