Struct ColumnScope 

pub struct ColumnScope { /* private fields */ }

A Column and its builder.

Implementations

impl ColumnScope

pub fn arrangement(self, arrangement: Arrangement) -> Self

How the children share the main axis.

pub fn spacing(self, dp: f32) -> Self

A literal gap between children, in dp.

pub fn space_role(self, role: SpaceRole) -> Self

A gap from the design system’s spacing ladder.

pub fn alignment(self, alignment: Alignment) -> Self

Where the children sit on the cross axis.

pub fn intrinsic_size(self, enabled: bool) -> Self

Sizes the cross axis to the tallest child in a Row or the widest child in a Column, so children with fill_max_height or fill_max_width match the largest sibling without an explicit container size.

impl ColumnScope

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

What sits around it. Compose’s modifier parameter.

impl ColumnScope

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

Composes this widget with content as its children.

impl ColumnScope

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 ColumnScope

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 ColumnScope

pub fn tear_off_key(self, key: impl Into<String>) -> Self

Lets the user pull this node out into a window of its own, named by key: the RestoreKey of the window that results.

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

Hears a dragged window pass over this node: where a tab row shows the place a dropped tab would go.

impl ColumnScope

pub fn equal_width(self, enabled: bool) -> Self

Sizes the column to its widest child so children with fill_max_width match their siblings’ width.

Trait Implementations

impl Drop for ColumnScope

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.
