Struct FixedSelection 

#[repr(transparent)]
pub struct FixedSelection {
    inner: TypedObjectRef<FixedSelection, ()>,
    phantom: PhantomData<()>,
}

A GtkSelectionModel that keeps track of the selected item even if its position changes or it is removed from the list.

GLib type: GObject with reference counted clone semantics.

Fields

inner: TypedObjectRef<FixedSelection, ()>

phantom: PhantomData<()>

Implementations

impl FixedSelection

pub fn model(&self) -> <BoundObject<ListModel> as Property>::Value

The underlying model.

pub fn set_model<'a>( &self, value: Option<impl Borrow<<<BoundObject<ListModel> as Property>::Value as HasParamSpec>::SetValue>>, )

The underlying model.

pub fn selected(&self) -> <Cell<u32> as Property>::Value

The position of the selected item.

pub fn set_selected<'a>( &self, value: impl Borrow<<<Cell<u32> as Property>::Value as HasParamSpec>::SetValue>, )

The position of the selected item.

pub fn selected_item(&self) -> <RefCell<Option<Object>> as Property>::Value

The selected item.

pub fn set_selected_item<'a>( &self, value: Option<impl Borrow<<<RefCell<Option<Object>> as Property>::Value as HasParamSpec>::SetValue>>, )

The selected item.

pub fn is_empty(&self) -> <PhantomData<bool> as Property>::Value

Whether the model is empty.

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

Listen for notifications of a change in the model property

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

Listen for notifications of a change in the selected property

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

Listen for notifications of a change in the selected-item property

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

Listen for notifications of a change in the is-empty property

pub fn notify_model(&self)

Notify listeners of a change in the model property

pub fn notify_selected(&self)

Notify listeners of a change in the selected property

pub fn notify_selected_item(&self)

Notify listeners of a change in the selected-item property

pub fn notify_is_empty(&self)

Notify listeners of a change in the is-empty property

impl FixedSelection

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

Construct a new FixedSelection with the given model.

pub(crate) fn set_item_equivalence_fn( &self, equivalence_fn: impl Fn(&Object, &Object) -> bool + 'static, )

Set the function to use to test for equivalence of two items.

It is used when checking if an object still present when the underlying model changes. Which means that if there are two equivalent objects at the same time in the underlying model, the selected item might change unexpectedly between those two objects.

If this is not set, the Eq implementation is used, meaning that they must be the same object.

Trait Implementations

impl Clone for FixedSelection

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 FixedSelection

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

Formats the value using the given formatter.

impl Default for FixedSelection

fn default() -> Self

Returns the “default value” for a type.

impl HasParamSpec for FixedSelection

type ParamSpec = ParamSpecObject

type SetValue = FixedSelection

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for FixedSelection

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 ObjectSubclassIs for FixedSelection

type Subclass = FixedSelection

impl Ord for FixedSelection

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 FixedSelection

type Parent = Object

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

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 FixedSelection

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 FixedSelection

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for FixedSelection

impl IsA<ListModel> for FixedSelection

impl IsA<SelectionModel> for FixedSelection
