Struct zng::render::HitTestBuilder

pub struct HitTestBuilder<'a> { /* private fields */ }

Builder for the hit-testable shape of the inner-bounds of a widget.

This builder is available in FrameBuilder::hit_test inside the inner-bounds of the rendering widget.

Implementations

impl<'a> HitTestBuilder<'a>

pub fn is_hit_testable(&self) -> bool

If the widget is hit-testable, if this is false all hit-test push methods are ignored.

pub fn push_rect(&mut self, rect: Rect<Px, Px>)

Push a hit-test rect.

pub fn push_rounded_rect( &mut self, rect: Rect<Px, Px>, corners: CornerRadius2D<Px, Px>, )

Push a hit-test rect with rounded corners.

pub fn push_ellipse(&mut self, center: Point2D<Px, Px>, radii: Size2D<Px, Px>)

Push a hit-test ellipse.

pub fn push_clip_rect( &mut self, rect: Rect<Px, Px>, clip_out: bool, inner_hit_test: impl FnOnce(&mut HitTestBuilder<'a>), )

Push a clip rect that affects the inner_hit_test.

pub fn push_clip_rounded_rect( &mut self, rect: Rect<Px, Px>, corners: CornerRadius2D<Px, Px>, clip_out: bool, inner_hit_test: impl FnOnce(&mut HitTestBuilder<'a>), )

Push a clip rect with rounded corners that affects the inner_hit_test.

pub fn push_clip_ellipse( &mut self, center: Point2D<Px, Px>, radii: Size2D<Px, Px>, clip_out: bool, inner_hit_test: impl FnOnce(&mut HitTestBuilder<'a>), )

Push a clip ellipse that affects the inner_hit_test.

pub fn push_clips( &mut self, clips: impl FnOnce(&mut HitTestClipBuilder<'_>), inner_hit_test: impl FnOnce(&mut HitTestBuilder<'a>), )

Push clips that affect the inner_hit_test.

pub fn push_transform( &mut self, transform: PxTransform, inner_hit_test: impl FnOnce(&mut HitTestBuilder<'a>), )

Pushes a transform that affects the inner_hit_test.

pub fn push_border( &mut self, bounds: Rect<Px, Px>, widths: SideOffsets2D<Px, Px>, corners: CornerRadius2D<Px, Px>, )

Pushes a composite hit-test that defines a border.
