Represents a widget in the access info tree.

Fields

id: AccessNodeId

Widget ID.

role: Option<AccessRole>

Accessibility role.

commands: Vec<AccessCmdName>

Commands the widget supports.

state: Vec<AccessState>

Accessibility state.

transform: PxTransform

Widget transform (in the parent space).

size: PxSize

Widget bounds size (in the transform space).

children: Vec<AccessNodeId>

Children, including nodes that are not present in the tree because they did not change since last update.

Can be empty if all children are present in the tree. If not empty it must contain all children, omitted and present, in the logical order.

See AccessTreeBuilder::push for more details.

children_len: u32

Number of children nodes actually present in the tree.

See AccessTreeBuilder::push for more details.

descendants_len: u32

Number of descendant nodes actually present in the tree.

See AccessTreeBuilder::push for more details.
