How to calculate the area occupied by an icon or checkbox in QListView?

Question

User interface

I'm trying to make a custom combobox. It has checkboxes, and when you click on the checkboxes, our combobox should not collapse. And for this, apparently, you will have to react in your own way if the user clicks on the checkbox with the mouse.
It should turn out something like this.

This is a real screenshot, so I don't think much code is required. At the moment, model.setData only fires when the spacebar is pressed, which is good. What about a mouse?

You can try to override the show / hidePopup methods, play with view() or put an event filter.
