styling focus rect in QTreeView

[wysota]

Is there a way to change the view of focus rect (dotted) around the active row?

Yes.

but I cannot find how to do that right.

Either have a custom delegate or use style-sheets.

item:selected:active is not the solution because I have many items selected and the "current cursor position" is the current item (currentIndex()) that is not selected by default in my QTreeView subclass.

That's ::item:active, isn't it?

Unfortunately, item:active affects all rows in QTreeView (I don't know why its happen). For example:

MyTreeView::item:active {background-color: blue;}

With such style, all rows will have blue background, and current row has the default white background.
So, as you suggets, I will look to the item delegation.
