QTreeView - Expanded and collapsed items
I need 2 options for my model:
- expand or collapse everything with one level
- Invert selection, but I don't want all items to be selected only the ones that can be seen (even by scrolling)
For the first one, I can use expandtoDepth, but I miss the point where Tree won't expand anymore, since it doesn't return if something was expanded.
For the second one, I know how to select items, but I want to select items that are not hidden because it's parent isn't expanded.
How can I implement this?
