Struct gtk4::NumericSorter

pub struct NumericSorter { /* private fields */ }

NumericSorter is a Sorter that compares numbers.

To obtain the numbers to compare, this sorter evaluates a Expression.

Properties

expression

The expression to evaluate on items to get a number to compare with.

Readable | Writeable

sort-order

Whether the sorter will sort smaller numbers first.

Implementations

impl NumericSorter

pub fn new(expression: Option<impl AsRef<Expression>>) -> NumericSorter

Creates a new numeric sorter using the given @expression.

Smaller numbers will be sorted first. You can call set_sort_order() to change this.

expression

The expression to evaluate

Returns

a new NumericSorter

pub fn builder() -> NumericSorterBuilder

Creates a new builder-pattern struct instance to construct NumericSorter objects.

This method returns an instance of NumericSorterBuilder which can be used to create NumericSorter objects.

pub fn expression(&self) -> Option<Expression>

Gets the expression that is evaluated to obtain numbers from items.

Returns

a Expression

pub fn sort_order(&self) -> SortType

Gets whether this sorter will sort smaller numbers first.

Returns

the order of the numbers

pub fn set_expression(&self, expression: Option<impl AsRef<Expression>>)

Sets the expression that is evaluated to obtain numbers from items.

Unless an expression is set on @self, the sorter will always compare items as invalid.

The expression must have a return type that can be compared numerically, such as G_TYPE_INT or G_TYPE_DOUBLE.

expression

a Expression

pub fn set_sort_order(&self, sort_order: SortType)

Sets whether to sort smaller numbers before larger ones.

sort_order

whether to sort smaller numbers first

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

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

Trait Implementations

impl Clone for NumericSorter

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NumericSorter

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

Formats the value using the given formatter.

impl Default for NumericSorter

fn default() -> Self

Returns the “default value” for a type.

impl HasParamSpec for NumericSorter

type ParamSpec = ParamSpecObject

type SetValue = NumericSorter

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for NumericSorter

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

where H: Hasher,

Feeds this value into the given Hasher.

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 NumericSorter

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

This method returns an Ordering between self and other.

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 + PartialOrd,

Restrict a value to a certain interval.

impl ParentClassIs for NumericSorter

type Parent = Sorter

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

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

This method tests for self and other values to be equal, and is used by ==.

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

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

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

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

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl StaticType for NumericSorter

fn static_type() -> Type

Returns the type identifier of Self.
