• Open Qt Assistant
• Look for QTreeWidget
• Go to Signals section and see which signal you really need - I assume itemClicked() or itemActivated() in you case
• Examine what info you get from the chosen signal - a QTreeWidgetItem may be?
• Go to QThreeWIdgetItem in Qt Assistant
• Look some functions that can help you - may be childCount() and parent() ?

Hope this helps
