Signal ID
Connect to RowActivated signal.
The "row-activated" signal is emitted when the method gtk.tree_view.TreeView.rowActivated is called, when the user double clicks a treeview row with the "activate-on-single-click" property set to false, or when the user single clicks a row when the "activate-on-single-click" property set to true. It is also emitted when a non-editable row is selected and one of the keys: Space, Shift+Space, Return or Enter is pressed.
For selection handling refer to the tree widget conceptual overview
as well as #GtkTreeSelection.
