Perhaps this code should be removed?
Rationale for this suggestion -
I made some googling on stylesheets, and noted we can achieve similar
functionality with
QTreeWidget:focus {
background-color: #fdf5f5; /* Leo's traditional tree color */
}
(i.e. we can use :focus mode selector to apply stylesheets without
writing any code).
This approach is undoubtedly simpler and faster (everything happens in
behind-the-scenes fast C++ code).
