Struct SliverGridParentData 

pub struct SliverGridParentData {
    pub cross_axis_offset: Option<f64>,
    /* private fields */
}

Parent data structure used by RenderSliverGrid.

Fields

cross_axis_offset: Option<f64>

The offset of the child in the non-scrolling axis.

If the scroll axis is vertical, this offset is from the left-most edge of the parent to the left-most edge of the child. If the scroll axis is horizontal, this offset is from the top-most edge of the parent to the top-most edge of the child.

Implementations

impl SliverGridParentData

pub const fn new() -> SliverGridParentData

Creates parent data with no index, layout offset or cross-axis offset.

Trait Implementations

impl ContainerParentDataMixin for SliverGridParentData

type ChildType = AnyRenderBox

The previous sibling in the parent’s child list.

fn set_previous_sibling(&mut self, value: Option<Self::ChildType>)

Sets previous_sibling.

fn next_sibling(&self) -> Option<Self::ChildType>
