In contrast with some other similar methods, currently the TreeViewItem::setSelected() method does not provide a sendNotification argument for choosing not to call the itemSelectionChanged() callback. I think that it could be a useful feature (for me it certainly would). Obviously, such parameter should be defaulting to true in order not to break current existing code.
Yes… I’ve been meaning to tidy up all of those “sendNotification” bools and convert them into enums or something that reads more clearly, so will probably look at this one when I do the others.
