sourcefn has_default_sort_func(&self) -> bool
fn has_default_sort_func(&self) -> bool
Returns true
if the model has a default sort function. This is used
primarily by GtkTreeViewColumns in order to determine if a model can
go back to the default state, or not.

sourcefn sort_column_changed(&self)
fn sort_column_changed(&self)
Emits a GtkTreeSortable::sort-column-changed
signal on @self.
Deprecated since 4.10
sourcefn connect_sort_column_changed<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
fn connect_sort_column_changed<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId
The ::sort-column-changed signal is emitted when the sort column or sort order of @sortable is changed. The signal is emitted before the contents of @sortable are resorted.
