Trait containing manually implemented methods of TreeSortable.
Provided Methods§
sourcefn set_default_sort_func<F>(&self, sort_func: F)where
F: Fn(&Self, &TreeIter, &TreeIter) -> Ordering + 'static,
fn set_default_sort_func<F>(&self, sort_func: F)where F: Fn(&Self, &TreeIter, &TreeIter) -> Ordering + 'static,
Sets the default comparison function used when sorting to be @sort_func.
If the current sort column id of @self is
GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID, then the model will sort using
this function.
If @sort_func is None, then there will be no default comparison function.
This means that once the model has been sorted, it can’t go back to the
default state. In this case, when the current sort column id of @self
is GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID, the model will be unsorted.
Deprecated since 4.10
sort_func
The comparison function
sourcefn set_sort_func<F>(&self, sort_column_id: SortColumn, sort_func: F)where
F: Fn(&Self, &TreeIter, &TreeIter) -> Ordering + 'static,
fn set_sort_func<F>(&self, sort_column_id: SortColumn, sort_func: F)where F: Fn(&Self, &TreeIter, &TreeIter) -> Ordering + 'static,
Sets the comparison function used when sorting to be @sort_func. If the current sort column id of @self is the same as @sort_column_id, then the model will sort using this function.
Deprecated since 4.10
sort_column_id
the sort column id to set the function for
sort_func
The comparison function
sourcefn sort_column_id(&self) -> Option<(SortColumn, SortType)>
fn sort_column_id(&self) -> Option<(SortColumn, SortType)>
Fills in @sort_column_id and @order with the current sort column and the
order. It returns true unless the @sort_column_id is
GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID or
GTK_TREE_SORTABLE_UNSORTED_SORT_COLUMN_ID.
Deprecated since 4.10
Returns
true if the sort column is not one of the special sort
column ids.
sort_column_id
The sort column id to be filled in
order
The SortType to be filled in
sourcefn set_sort_column_id(&self, sort_column_id: SortColumn, order: SortType)
fn set_sort_column_id(&self, sort_column_id: SortColumn, order: SortType)
Sets the current sort column to be @sort_column_id. The @self will
resort itself to reflect this change, after emitting a
GtkTreeSortable::sort-column-changed signal. @sort_column_id may either be
a regular column id, or one of the following special values:
-
GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID: the default sort function will be used, if it is set -
GTK_TREE_SORTABLE_UNSORTED_SORT_COLUMN_ID: no sorting will occur
Deprecated since 4.10
sort_column_id
the sort column id to set
order
The sort order of the column
