Implementations

impl GroupingListGroup

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

The underlying model.

pub fn start(&self) -> <PhantomData<u32> as Property>::Value

The position of the first item in this group.

pub fn end(&self) -> <PhantomData<u32> as Property>::Value

The position of the last item in this group.

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

Listen for notifications of a change in the start property

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

Listen for notifications of a change in the end property

pub fn notify_model(&self)

Notify listeners of a change in the model property

pub fn notify_start(&self)

Notify listeners of a change in the start property

pub fn notify_end(&self)

Notify listeners of a change in the end property

impl GroupingListGroup

pub fn new(model: &ListModel, range: RangeInclusive<u32>) -> Self

Construct a new GroupingListGroup for the given model and range.

pub(super) fn bounds(&self) -> (u32, u32)

The bounds of this group.

pub(super) fn contains(&self, position: u32) -> bool

Whether this group contains the given position.

pub(super) fn handle_removal(&self, position: u32, removed: u32)

Handle the given removal of items that might affect this group.

This function panics if there would be no items left in this group.

pub(super) fn handle_addition(&self, position: u32, added: u32)

Handle the given addition of items that might affect this group.

pub(super) fn add(&self, position: u32, added: u32)

Add items to this list item.

This function assumes that the new items are contiguous to the current ones.

pub(super) fn has_batch(&self) -> bool

Whether this group has an accumulated batch of changes.

pub(super) fn process_batch(&self)

Process the accumulated batch of changes.

pub(super) fn drop_batch(&self)

Drop the accumulated batch of changes.

Trait Implementations

impl Clone for GroupingListGroup

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 GroupingListGroup

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

Formats the value using the given formatter.

impl HasParamSpec for GroupingListGroup

type ParamSpec = ParamSpecObject

type SetValue = GroupingListGroup

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for GroupingListGroup

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 GroupingListGroup

type Subclass = GroupingListGroup

impl Ord for GroupingListGroup

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 GroupingListGroup

type Parent = Object

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

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 GroupingListGroup

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 GroupingListGroup

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for GroupingListGroup

impl IsA<ListModel> for GroupingListGroup
