Expand description

Trait containing manually implemented methods of TreeSortable.

Provided Methods§

Source

fn set_default_sort_func<F>(&self, sort_func: F)
where F: Fn(&Self, &TreeIter, &TreeIter) -> Ordering + 'static,

👎Deprecated:

Since 4.10

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

Source

fn set_sort_func<F>(&self, sort_column_id: SortColumn, sort_func: F)
where F: Fn(&Self, &TreeIter, &TreeIter) -> Ordering + 'static,

👎Deprecated:

Since 4.10

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

Source

fn sort_column_id(&self) -> Option<(SortColumn, SortType)>

👎Deprecated:

Since 4.10

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

Source

fn set_sort_column_id(&self, sort_column_id: SortColumn, order: SortType)

👎Deprecated:

Since 4.10

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

Source

fn set_unsorted(&self)

👎Deprecated:

Since 4.10

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
