Struct ScrollContainer

Source

pub struct ScrollContainer { /* private fields */ }

Expand description

A scroll container that offsets content and supports virtual scrolling.

Implementations§

Source §

impl ScrollContainer

Source

pub fn new(direction: ScrollDirection) -> Self

Source

pub fn offset(self, offset: f32) -> Self

Set scroll offset (combined x/y based on direction).

Source

pub fn offset_xy(self, x: f32, y: f32) -> Self

Source

pub fn viewport(&self, area: Rect) -> Rect

The viewport rect (visible portion) given the area.

Source

pub fn max_offset(&self, content: DesiredSize, viewport: Rect) -> (f32, f32)

Maximum scroll offset given content and viewport sizes.

Trait Implementations§

Source §

impl Layout for ScrollContainer

Source §

fn measure( &self, children: &[DesiredSize], constraints: SizeConstraints, ) -> DesiredSize

Compute the desired size of this layout given child sizes and constraints.

Source §

fn arrange(&self, children: &[DesiredSize], area: Rect) -> Vec<Rect>

Arrange children within the given area, returning a positioned rect per child.

where T: ?Sized,

Source §

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> Downcast<T> for T

Source §

fn downcast(&self) -> &T

Source §

impl<T> Downcast for T
where T: Any,

Source §

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

Source §

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

Source §

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

Source §

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

Source §

impl<T> DowncastSync for T
where T: Any + Send + Sync,

Source §

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Send + Sync>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.

Source §

impl<T> From<T> for T

Source §

fn from(t: T) -> T

Returns the argument unchanged.

Source §

impl<T> Instrument for T

Source §

fn instrument(self, span: Span) -> Instrumented<Self>

Instruments this type with the provided Span, returning an Instrumented wrapper. Read more

Source §

fn in_current_span(self) -> Instrumented<Self>

Instruments this type with the current Span, returning an Instrumented wrapper. Read more

Source §

impl<T, U> Into for T
where U: From<T>,

Source §

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

Source §

impl<T> IntoEither for T

Source §

fn into_either(self, into_left: bool) -> Either<Self, Self>

Converts self into a Left variant of Either<Self, Self> if into_left is true. Converts self into a Right variant of Either<Self, Self> otherwise. Read more

Source §

fn into_either_with<F>(self, into_left: F) -> Either<Self, Self>
where F: FnOnce(&Self) -> bool,

Converts self into a Left variant of Either<Self, Self> if into_left(&self) returns true. Converts self into a Right variant of Either<Self, Self> otherwise. Read more
