Required Methods§

source

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.

Returns

true, if the model has a default sort function

source

fn sort_column_changed(&self)

Emits a GtkTreeSortable::sort-column-changed signal on @self.

source

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.
