Struct ColumnViewCell

pub struct ColumnViewCell { /* private fields */ }

Available on crate feature v4_12 only.

ColumnViewCell is used by ColumnViewColumn to represent items in a cell in ColumnView.

The ColumnViewCells are managed by the columnview widget (with its factory) and cannot be created by applications, but they need to be populated by application code. This is done by calling set_child().

ColumnViewCells 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.

Implementations

impl ColumnViewCell

pub fn builder() -> ColumnViewCellBuilder

Creates a new builder-pattern struct instance to construct ColumnViewCell objects.

This method returns an instance of ColumnViewCellBuilder which can be used to create ColumnViewCell objects.

pub fn child(&self) -> Option<Widget>

Gets the child previously set via gtk_column_view_cell_set_child() or None if none was set.

Returns

The child

pub fn item(&self) -> Option<Object>

Gets the model item that associated with @self.

If @self is unbound, this function returns None.

Returns

The item displayed

pub fn position(&self) -> u32

Gets the position in the model that @self currently displays.

If @self is unbound, GTK_INVALID_LIST_POSITION is returned.

Returns

The position of this item

pub fn is_selected(&self) -> bool

Checks if the item is displayed as selected.

The selected state is maintained by the list widget and its model and cannot be set otherwise.

Returns

true if the item is selected.

pub fn set_child(&self, child: Option<&impl IsA<Widget>>)

Sets the child to be used for this listitem.

This function is typically called by applications when setting up a listitem so that the widget can be reused when binding it multiple times.

child

The list item’s child or None to unset

Trait Implementations

impl Clone for ColumnViewCell

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 ColumnViewCell

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

Formats the value using the given formatter.

impl HasParamSpec for ColumnViewCell

type ParamSpec = ParamSpecObject

type SetValue = ColumnViewCell

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for ColumnViewCell

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 ColumnViewCell

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 ColumnViewCell

type Parent = ListItem

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

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 ColumnViewCell

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 ColumnViewCell

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for ColumnViewCell

impl IsA<ListItem> for ColumnViewCell
