Struct ribir::prelude::SizedBox

pub struct SizedBox {
    pub size: Size2D<f32, LogicUnit>,
}

A box with a specified size.

This widget forces its child to have a specific width and/or height (assuming values are permitted by the parent of this widget).

Fields

size: Size2D<f32, LogicUnit>

Implementations

impl SizedBox

pub fn set_declare_size(&mut self, v: Size2D<f32, LogicUnit>)

Trait Implementations

impl Clone for SizedBox

fn clone(&self) -> SizedBox

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Declare for SizedBox

type Builder = SizedBoxDeclarer

fn declare_builder() -> <SizedBox as Declare>::Builder

impl Query for SizedBox

fn query_all( &self, type_id: TypeId, callback: &mut dyn FnMut(&(dyn Any + 'static)) -> bool, _: QueryOrder )

A type can composed by others, this method query all type(include self) match the type id, and call the callback one by one. The callback accept an & dyn Any of the target type, and return if it want to continue.

impl Render for SizedBox

fn perform_layout( &self, _: BoxClamp, ctx: &mut LayoutCtx<'_> ) -> Size2D<f32, LogicUnit>

Do the work of computing the layout for this widget, and return the size it need.

fn only_sized_by_parent(&self) -> bool

Whether the constraints from parent are the only input to detect the widget size, and child nodes’ size not affect its size.

fn paint(&self, ctx: &mut PaintingCtx<'_>)

paint is a low level trait to help you draw your widget to paint device across PaintingCtx::painter by itself coordinate system. Not care about children’s paint in this method, framework will call children’s paint individual. And framework guarantee always paint parent before children.

fn can_overflow(&self) -> bool

Hint if a render maybe paint over its layout boundary.

fn hit_test(&self, ctx: &HitTestCtx<'_>, pos: Point2D<f32, LogicUnit>) -> HitTest

Determines the set of render widgets located at the given position.

fn get_transform(&self) -> Option<Transform2D<f32, LogicUnit, LogicUnit>>
