Expand description

Parent data for a RenderBox subclass that uses ContainerRenderObjectMixin.

Flutter’s ContainerBoxParentData: a convenience class that mixes ContainerParentDataMixin into a BoxParentData. Here it is the pair of accessors a container’s parent data provides, one for each half.

Required Methods§

Source

fn box_parent_data(&self) -> &BoxParentData

Mixin field access: the BoxParentData half.

ParentData::provide must answer BoxParentData with the same value, or the box protocol cannot position this child.

Source

fn box_parent_data_mut(&mut self) -> &mut BoxParentData

See box_parent_data.

Provided Methods§

Source

fn offset(&self) -> Offset

The offset at which to paint the child in the parent’s coordinate system.

Source

fn set_offset(&mut self, value: Offset)

Sets offset.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
