Readable

model

The model being filtered.

Implementations

impl SelectionFilterModel

pub fn new(model: Option<&impl IsA<SelectionModel>>) -> SelectionFilterModel

Creates a new SelectionFilterModel that will include the selected items from the underlying selection model.

model

the selection model to filter

Returns

a new SelectionFilterModel

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

Gets the model currently filtered or None if none.

Returns

The model that gets filtered

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

Sets the model to be filtered.

Note that GTK makes no effort to ensure that @model conforms to the item type of @self. It assumes that the caller knows what they are doing and have set up an appropriate filter to ensure that item types match.

model

The model to be filtered

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

Trait Implementations

impl Clone for SelectionFilterModel

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 SelectionFilterModel

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

Formats the value using the given formatter.

impl HasParamSpec for SelectionFilterModel

type ParamSpec = ParamSpecObject

type SetValue = SelectionFilterModel

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for SelectionFilterModel

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 SelectionFilterModel

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 SelectionFilterModel

type Parent = Object

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

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 SelectionFilterModel

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 SelectionFilterModel

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for SelectionFilterModel
