QTreeWidget: how to make the item cursor (dotted frame) invisible?

[Violet Giraffe]

I have set selection mode to NoSelection, but I still get the cursor frame. How can I get rid of it?

Well, its has been discussed before.

@mrjj
There's no answer there. People discuss outline: none;, but it does not remove the cursor frame. I don't know what it does.

They also try to remove the focus rect which is what you see in the picture.
It can be removed using a Delegate and draw nothing.
