Struct AlertDialogCloseTrigger 

pub struct AlertDialogCloseTrigger { /* private fields */ }

AlertDialog.CloseTrigger — the dialog’s close slot, absolute end-4 top-4.

v3 spells visibility by composing or omitting the part: a composed AlertDialogCloseTrigger renders in the slot and an omitted one leaves it bare panel padding — there is no hideCloseButton and no automatic stand-in. The part is v3’s wired CloseButton (slot="close"), always wired to onOpenChange(false) alone — never to AlertDialog::on_cancel — and closing regardless of is_dismissible or is_keyboard_dismiss_disabled, like v3’s composed trigger. Custom children only replace the button’s glyph — the press still runs the dialog’s close action. Without an on_open_change — or composed outside an AlertDialog — the part draws nothing.

Implementations

impl AlertDialogCloseTrigger

pub fn new() -> Self

Creates a close trigger with no children.

Trait Implementations

impl Default for AlertDialogCloseTrigger

fn default() -> Self

Returns the “default value” for a type.

impl Element for AlertDialogCloseTrigger

type RequestLayoutState = AnyElement

The type of state returned from Element::request_layout. A mutable reference to this state is subsequently provided to Element::prepaint and Element::paint.

type PrepaintState = ()

The type of state returned from Element::prepaint. A mutable reference to this state is subsequently provided to Element::paint.

fn id(&self) -> Option<ElementId>

If this element has a unique identifier, return it here. This is used to track elements across frames, and will cause a GlobalElementId to be passed to the request_layout, prepaint, and paint methods.

fn source_location(&self) -> Option<&'static Location<'static>>

Source location where this element was constructed, used to disambiguate elements in the inspector and navigate to their source code.

fn request_layout( &mut self, _: Option<&GlobalElementId>, _: Option<&InspectorElementId>, window: &mut Window, cx: &mut App, ) -> (LayoutId, Self::RequestLayoutState)

Before an element can be painted, we need to know where it’s going to be and how big it is. Use this method to request a layout from Taffy and initialize the element’s state.

fn prepaint( &mut self, _: Option<&GlobalElementId>, _: Option<&InspectorElementId>, _: Bounds<Pixels>, state: &mut Self::RequestLayoutState, window: &mut Window, cx: &mut App, ) -> Self::PrepaintState

After laying out an element, we need to commit its bounds to the current frame for hitbox purposes. The state argument is the same state that was returned from Element::request_layout().

fn paint( &mut self, _: Option<&GlobalElementId>, _: Option<&InspectorElementId>, _: Bounds<Pixels>, state: &mut Self::RequestLayoutState, _: &mut Self::PrepaintState, window: &mut Window, cx: &mut App, )

Once layout has been completed, this method will be called to paint the element to the screen. The state argument is the same state that was returned from Element::request_layout().

fn a11y_role(&self) -> Option<Role>

Returns the accessible role for this element, if any. Elements that return None are not included in the accessibility tree.

fn write_a11y_info(&self, _node: &mut Node)

Write accessibility properties to the given node. Called only when a11y_role() returns Some.

fn a11y_synthetic_children( &mut self, _prepaint: &mut Self::PrepaintState, _builder: &mut A11ySubtreeBuilder<'_>, )

Add synthetic child nodes to an Element that has an .id() and a .role().

fn into_any(self) -> AnyElement

Convert this element into a dynamically-typed AnyElement.

impl IntoElement for AlertDialogCloseTrigger

type Element = AlertDialogCloseTrigger

The specific type of element into which the implementing type is converted. Useful for converting other types into elements automatically, like Strings

fn into_element(self) -> Self

Convert self into a type that implements Element.

fn into_any_element(self) -> AnyElement

Convert self into a dynamically-typed AnyElement.

impl ParentElement for AlertDialogCloseTrigger

fn extend(&mut self, elements: impl IntoIterator<Item = AnyElement>)

Extend this element’s children with the given child elements.

fn child(self, child: impl IntoElement) -> Self

where Self: Sized,

Add a single child element to this element.

fn children(self, children: impl IntoIterator<Item = impl IntoElement>) -> Self

where Self: Sized,

Add multiple child elements to this element.
