Struct BoxDecoration 

pub struct BoxDecoration {
    pub background: Option<Brush>,
    pub border: Option<Border>,
    pub border_radius: Option<Radius>,
}

The BoxDecoration provides a variety of ways to draw a box.

Fields

background: Option<Brush>

The background of the box.

border: Option<Border>

A border to draw above the background

border_radius: Option<Radius>

The corners of this box are rounded by this BorderRadius. The round corner only work if the two borders beside it are same style.

Trait Implementations

impl Clone for BoxDecoration

fn clone(&self) -> BoxDecoration

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Declare for BoxDecoration

type Builder = FatObj<()>

fn declarer() -> Self::Builder

impl Default for BoxDecoration

fn default() -> BoxDecoration

Returns the “default value” for a type.

impl Query for BoxDecoration

fn query_inside_first( &self, type_id: TypeId, callback: &mut dyn FnMut(&dyn Any) -> bool, ) -> bool

Query the type in a inside first order, and apply the callback to it. return what the callback return, hint if the query should continue.

fn query_outside_first( &self, type_id: TypeId, callback: &mut dyn FnMut(&dyn Any) -> bool, ) -> bool

Query the type in a outside first order, and apply the callback to it, return what the callback return, hint if the query should continue.

impl Render for BoxDecoration

fn perform_layout(&self, clamp: BoxClamp, ctx: &mut LayoutCtx<'_>) -> Size

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

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 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 hit_test(&self, ctx: &HitTestCtx, pos: Point) -> HitTest

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

fn get_transform(&self) -> Option<Transform>

impl SingleChild for BoxDecoration
