Struct SelectionContainerScope 

pub struct SelectionContainerScope { /* private fields */ }

A SelectionContainer and its builder.

Implementations

impl SelectionContainerScope

pub fn modifier(self, modifier: Modifier) -> Self

What sits around it. Compose’s modifier parameter.

impl SelectionContainerScope

pub fn content(self, content: impl FnOnce())

Composes this widget with content as its children.

impl SelectionContainerScope

pub fn on_pointer( self, kinds: PointerKinds, handler: impl FnMut(PointerEvent) + 'static, ) -> Self

Subscribes the node to the kinds of pointer input in kinds. The handler runs on the same call as the input; calling consume on the event keeps it from the nearest subscribed ancestor and from the Renderer’s own handling.

A node that never calls this has no pointer input at all, and costs nothing.

impl SelectionContainerScope

pub fn on_click(self, handler: impl FnMut() + 'static) -> Self

Makes the container a button. The Renderer gives it keyboard focus, runs the handler on a click and on Enter or Space, announces it to assistive technology as a button, and shows hover, pressed and focus state.

A container that never calls this is not a control and costs nothing.

impl SelectionContainerScope

pub fn on_focus_gained(self, handler: impl FnMut() + 'static) -> Self

Runs when this node or a descendant inside it gains keyboard focus.

pub fn on_focus_lost(self, handler: impl FnMut() + 'static) -> Self

Runs when this node and its descendants lose keyboard focus.

pub fn on_key_down(self, handler: impl FnMut(KeyEvent) + 'static) -> Self

Sees each key pressed while this node or a descendant inside it holds focus; calling consume on the event keeps the Renderer from acting on it.

pub fn on_key_up(self, handler: impl FnMut(KeyEvent) + 'static) -> Self

Sees each key released while this node or a descendant inside it holds focus.

pub fn focus_handle(self, handle: &FocusHandle) -> Self

Binds handle to this node, so handle.request() puts keyboard focus here.

Trait Implementations

impl Drop for SelectionContainerScope

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
