Struct gtk4::NoSelection

#[repr(transparent)]
pub struct NoSelection { /* private fields */ }

NoSelection is a SelectionModel that does not allow selecting anything.

This model is meant to be used as a simple wrapper around a GListModel when a SelectionModel is required.

NoSelection passes through sections from the underlying model.

Properties

item-type

The type of items. See [ListModelExtManual::item_type()][crate::gio::prelude::ListModelExtManual::item_type()].

Readable

model

The model being managed.

n-items

The number of items. See [ListModelExtManual::n_items()][crate::gio::prelude::ListModelExtManual::n_items()].

Implementations

impl NoSelection

pub fn new(model: Option<impl IsA<ListModel>>) -> NoSelection

Creates a new selection to handle @model.

model

the GListModel to manage

Returns

a new NoSelection

pub fn model(&self) -> Option<ListModel>

Gets the model that @self is wrapping.

Returns

The model being wrapped

pub fn set_model(&self, model: Option<&impl IsA<ListModel>>)

Sets the model that @self should wrap.

If @model is None, this model will be empty.

model

A GListModel to wrap

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

Trait Implementations

impl Clone for NoSelection

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 NoSelection

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

Formats the value using the given formatter.

impl Display for NoSelection

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

Formats the value using the given formatter.

impl HasParamSpec for NoSelection

type ParamSpec = ParamSpecObject

type SetValue = NoSelection

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for NoSelection

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 NoSelection

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl ParentClassIs for NoSelection

type Parent = Object

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

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 NoSelection

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 NoSelection

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for NoSelection

impl IsA<ListModel> for NoSelection

impl IsA<SectionModel> for NoSelection

impl IsA<SelectionModel> for NoSelection
