I have QTreeView and I want multi selection behavior in case if node is leaf, otherwise single selection behavior, so do not allow to select non-leaf node if some node already selected, and do not allow to select any other node if non-leaf node is selected.
How to implement that?

You may try to control selection behavior by deriving from
QTreeViewand overloadingselectionCommand.Using this method you can check what item was clicked (node/leaf) and then return proper
SelectionFlags.
