Struct ListItem

pub struct ListItem { /* private fields */ }

ListItem is used by list widgets to represent items in a gio::ListModel.

ListItem objects are managed by the list widget (with its factory) and cannot be created by applications, but they need to be populated by application code. This is done by calling ListItemExt::set_child().

ListItem objects exist in 2 stages:

1. The unbound stage where the listitem is not currently connected to an item in the list. In that case, the item property is set to None.

2. The bound stage where the listitem references an item from the list. The item property is not None.

Properties

accessible-description

The accessible description to set on the list item.

Readable | Writeable

accessible-label

The accessible label to set on the list item.

Readable | Writeable

activatable

If the item can be activated by the user.

Readable | Writeable

child

Widget used for display.

Readable | Writeable

focusable

If the item can be focused with the keyboard.

Readable | Writeable

item

Displayed item.

Readable

position

Position of the item.

Readable

selectable

If the item can be selected by the user.

Readable | Writeable

selected

If the item is currently selected.

Implements

ListItemExt, [trait@glib::ObjectExt]

GLib type: GObject with reference counted clone semantics.

Implementations

impl ListItem

pub const NONE: Option<&'static ListItem> = None

Trait Implementations

impl Clone for ListItem

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 ListItem

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

Formats the value using the given formatter.

impl HasParamSpec for ListItem

type ParamSpec = ParamSpecObject

type SetValue = ListItem

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for ListItem

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 Ord for ListItem

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 ListItem

type Parent = Object

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

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 ListItem

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 ListItem

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for ListItem

impl IsA<ListItem> for ColumnViewCell
