Struct zng_app::widget::border::BORDER

pub struct BORDER;

Coordinates nested borders and corner-radius.

Implementations

impl BORDER

pub fn border_offsets(&self) -> PxSideOffsets

Gets the accumulated border offsets on the outside of the current border set on the current widget.

This is only valid to call during layout.

pub fn inner_offsets(&self) -> PxSideOffsets

Gets the accumulated border offsets including the current border.

pub fn border_radius(&self) -> PxCornerRadius

Gets the corner radius for the border at the current context.

This value is influenced by CORNER_RADIUS_VAR, CORNER_RADIUS_FIT_VAR and all contextual borders.

pub fn inner_radius(&self) -> PxCornerRadius

Gets the corner radius for the inside of the current border at the current context.

pub fn outer_radius(&self) -> PxCornerRadius

Gets the corner radius for the outside of the outer border of the current widget.

pub fn fill_bounds(&self) -> (PxRect, PxCornerRadius)

Gets the bounds and corner radius for the widget fill content.

Must be called during layout in FILL nesting group.

This value is influenced by CORNER_RADIUS_VAR, CORNER_RADIUS_FIT_VAR and BORDER_ALIGN_VAR.

pub fn measure_border( &self, offsets: PxSideOffsets, f: impl FnOnce() -> PxSize, ) -> PxSize

Measure a border node, adding the offsets to the context for the f call.

pub fn layout_border(&self, offsets: PxSideOffsets, f: impl FnOnce())

Measure a border node, adding the offsets to the context for the f call.

pub fn with_corner_radius<R>(&self, f: impl FnOnce() -> R) -> R

Indicates a boundary point where the CORNER_RADIUS_VAR backing context changes during layout.

The variable must have been just rebound before this call, the corner_radius property implements this method.

Note that the corner radius is not set during measure.

pub fn border_layout(&self) -> (PxRect, PxSideOffsets)

Gets the computed border rect and side offsets for the border visual.

This is only valid to call in the border visual node during layout and render.

pub fn with_border_layout( &self, rect: PxRect, offsets: PxSideOffsets, f: impl FnOnce(), )

Sets the border layout for the context of f.
