Gtk.TreeModelSort.prototype.convert_child_iter_to_iter

function convert_child_iter_to_iter(child_iter:Gtk.TreeIter):Boolean {
    // Gjs wrapper for gtk_tree_model_sort_convert_child_iter_to_iter()
}

Sets sort_iter to point to the row in tree_model_sort that corresponds to the row pointed at by child_iter. If sort_iter was not set, false is returned. Note: a boolean is only returned since 2.14.

child_iter: A valid Gtk.TreeIter pointing to a row on the child model
Returns: true, if sort_iter was set, i.e. if sort_iter is a valid iterator pointer to a visible row in the child model.
