Struct TreeListRowSorter

pub struct TreeListRowSorter { /* private fields */ }

TreeListRowSorter is a special-purpose sorter that will apply a given sorter to the levels in a tree.

Here is an example for setting up a column view with a tree model and a GtkTreeListSorter:

⚠️ The following code is in c ⚠️

column_sorter = gtk_column_view_get_sorter (view);
sorter = gtk_tree_list_row_sorter_new (g_object_ref (column_sorter));
sort_model = gtk_sort_list_model_new (tree_model, sorter);
selection = gtk_single_selection_new (sort_model);
gtk_column_view_set_model (view, G_LIST_MODEL (selection));

Properties

sorter

The underlying sorter

Implements

SorterExt, [trait@glib::ObjectExt]

GLib type: GObject with reference counted clone semantics.

Implementations

impl TreeListRowSorter

pub fn new(sorter: Option<impl IsA<Sorter>>) -> TreeListRowSorter

Create a special-purpose sorter that applies the sorting of @sorter to the levels of a TreeListModel.

Note that this sorter relies on passthrough being false as it can only sort TreeListRows.

sorter

a Sorter

Returns

a new TreeListRowSorter

pub fn sorter(&self) -> Option<Sorter>

Returns the sorter used by @self.

Returns

the sorter used

pub fn set_sorter(&self, sorter: Option<&impl IsA<Sorter>>)

Sets the sorter to use for items with the same parent.

This sorter will be passed the item of the tree list rows passed to @self.

sorter

The sorter to use

pub fn connect_sorter_notify<F: Fn(&Self) + 'static>( &self, f: F, ) -> SignalHandlerId

Trait Implementations

impl Clone for TreeListRowSorter

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TreeListRowSorter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl HasParamSpec for TreeListRowSorter

type ParamSpec = ParamSpecObject

type SetValue = TreeListRowSorter

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, TreeListRowSorter>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for TreeListRowSorter

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Hashes the memory address of this object.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for TreeListRowSorter

fn cmp(&self, other: &Self) -> Ordering

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl ParentClassIs for TreeListRowSorter

type Parent = Sorter

impl<OT: ObjectType> PartialEq<OT> for TreeListRowSorter

fn eq(&self, other: &OT) -> bool

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<OT: ObjectType> PartialOrd<OT> for TreeListRowSorter

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for TreeListRowSorter

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for TreeListRowSorter

impl IsA<Sorter> for TreeListRowSorter
