I use QTreeView's selectionChanged signal. But you should also look at
QAbstractItemView's signals; it has many for you to choose from:
activated, clicked, doubleClicked, entered, pressed, ...

Subject: [PyQt] selecting an item in qtreeview
When using qtreewidget, I can use the itemClicked method to then call a
def:
self.treeWidget_iRulesList.itemClicked.connect(self.displayRule)
However, I hit a wall in trying to pass data around this way, so I
watched some tutorials on how to set up a model view and abstract the
data from the GUI components. This involved switching from a treeWidget
to a treeView. This works great in populating the tree, but now I don't
know how to signal a clicked item and pass that item (and the tree
parent it belongs to) to my displayRule def. Any thoughts?
