I've got some code which is doing stuff with NSOutlineView.
All that is happening, is I am moving an item up and down, via a
pushbutton.
So, the user selects a row, presses "Up", and sees the row moving up
by one. The moved row should then stay selected, at it's new position.
So, what my code does is this:
1) it modifies the ObjC tree-node class I that my outlineview's
delegate processes. The node is moved up within the children.
2) We call NSOutlineView reloadItem with the parameter as the parent
of the tree-node selected.
At this point, the parent the treenode are both visually displayed
already.
I've also confirmed that this does call correctly through to the
delegate method outlineView:child:ofItem:
3) We get the new row of the treenode, via rowForItem. This returns
the wrong result.
What is going wrong here? Is my code buggy? Or is my understanding of
NSOutlineView wrong?
