Trait containing all TreeModelSort methods.

§Implementors

TreeModelSort

Provided Methods§

Source

fn clear_cache(&self)

👎Deprecated:

Since 4.10

t change often) and there has been a lot of unreffed access to nodes. As a side effect of this function, all unreffed iters will be invalid.

§Deprecated since 4.10
Source

fn convert_child_iter_to_iter(&self, child_iter: &TreeIter) -> Option<TreeIter>

👎Deprecated:

Since 4.10

Sets @sort_iter to point to the row in @self 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.

§Deprecated since 4.10
§child_iter

A valid 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.

§sort_iter

An uninitialized TreeIter

Source

fn convert_child_path_to_path(&self, child_path: &TreePath) -> Option<TreePath>

👎Deprecated:

Since 4.10

t a valid path on the child model, then None is returned.

§Deprecated since 4.10
§child_path

A TreePath to convert

§Returns

A newly allocated TreePath

Source

fn convert_iter_to_child_iter(&self, sorted_iter: &TreeIter) -> TreeIter

👎Deprecated:

Since 4.10

Sets @child_iter to point to the row pointed to by @sorted_iter.

§Deprecated since 4.10
§sorted_iter

A valid TreeIter pointing to a row on @self.

§Returns
§child_iter

An uninitialized TreeIter

Source

fn convert_path_to_child_path(&self, sorted_path: &TreePath) -> Option<TreePath>

👎Deprecated:

Since 4.10

Converts @sorted_path to a path on the child model of @self. That is, @sorted_path points to a location in @self. The returned path will point to the same location in the model not being sorted. If @sorted_path does not point to a location in the child model, None is returned.

§Deprecated since 4.10
§sorted_path

A TreePath to convert

§Returns

A newly allocated TreePath

Source

fn model(&self) -> TreeModel

👎Deprecated:

Since 4.10

Returns the model the TreeModelSort is sorting.

§Deprecated since 4.10
§Returns

the “child model” being sorted

Source

fn iter_is_valid(&self, iter: &TreeIter) -> bool

👎Deprecated:

Since 4.10

purposes.

Checks if the given iter is a valid iter for this TreeModelSort.

§Deprecated since 4.10
§iter

A TreeIter

§Returns

true if the iter is valid, false if the iter is invalid.

Source

fn reset_default_sort_func(&self)

👎Deprecated:

Since 4.10

Dyn Compatibility§

This trait is not dyn compatible.

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