How do I perform an action when the user clicks on the title column of a TreeView?
The TreeViewColumn has a “clicked” signal, which you can attach any callback to. More information at [www.moeraki.com] The callback will receive as an argument the clicked column instance, and you can either attach data to the TreeViewColumn or pass user data in when you connect the signal (for example a key or column number). You’ll usually do this when adding the columns to the TreeView.
