Gtk.TreeView.prototype.set_cursor

function set_cursor(path:Gtk.TreePath, focus_column:Gtk.TreeViewColumn, start_editing:Boolean):void {
    // Gjs wrapper for gtk_tree_view_set_cursor()
}

Sets the current keyboard focus to be at path, and selects it. This is useful when you want to focus the user's attention on a particular row. If focus_column is not null, then focus is given to the column specified by it. Additionally, if focus_column is specified, and start_editing is true, then editing should be started in the specified cell. This function is often followed by @gtk_widget_grab_focus (tree_view) in order to give keyboard focus to the widget. Please note that editing can only happen when the widget is realized.

If path is invalid for @model, the current cursor (if any) will be unset and the function will return without failing.
