Struct SliverPhysicalContainerParentData 

pub struct SliverPhysicalContainerParentData { /* private fields */ }

Parent data for slivers that have multiple children and that position their children using absolute coordinates.

Implementations

impl SliverPhysicalContainerParentData

pub const fn new() -> SliverPhysicalContainerParentData

Creates parent data with a zero paint offset and no siblings.

pub fn sliver_physical_parent_data(&self) -> &SliverPhysicalParentData

The SliverPhysicalParentData half.

pub fn sliver_physical_parent_data_mut( &mut self, ) -> &mut SliverPhysicalParentData

See sliver_physical_parent_data.

pub fn paint_offset(&self) -> Offset

See SliverPhysicalParentData::paint_offset.

pub fn set_paint_offset(&mut self, value: Offset)

Sets paint_offset.

pub fn apply_paint_transform(&self, transform: &mut Matrix4)

See SliverPhysicalParentData::apply_paint_transform.
