public virtual signal void row_activated (TreePath path, TreeViewColumn? column)
The "row-activated" signal is emitted when the method [`method@Gtk.
TreeView.row_activated`] is called.
This signal is emitted when the user double-clicks a treeview row with the [[email protected]:activate-on-single-click] property set to false, or when the user single-clicks a row when that property set to true .
This signal is also emitted when a non-editable row is selected and one of the keys: <kbd>Space</kbd>, <kbd>Shift< /kbd>+<kbd>Space</kbd>, <kbd>Return</kbd> or <kbd>Enter</kbd> is pressed.
For selection handling refer to the [tree widget conceptual overview](section-tree-widget.html) as well as `GtkTreeSelection`.
