Struct SemanticsNode 

pub struct SemanticsNode {
    pub id: WidgetId,
    pub parent: Option<WidgetId>,
    pub children: Vec<WidgetId>,
    pub role: Role,
    pub label: Option<String>,
    pub value: Option<String>,
    pub bounds: Rect,
    pub focusable: bool,
    pub disabled: bool,
    pub focused: bool,
    pub pressable: bool,
}

One node of the projected tree, in the form a backend reads.

id, parent and children name projected nodes only, so the backend can build a tree whose nodes all carry a role. children is the list the projection reports: the children of an unprojected widget attach to the nearest projected ancestor.

Fields

id: WidgetId

The id of the widget this node projects.

parent: Option<WidgetId>

The id of the nearest projected ancestor, or None for the root.

children: Vec<WidgetId>

The ids of the projected children, in paint order.

role: Role

The kind of control the node represents.

label: Option<String>

The accessible name.

value: Option<String>

The current value.

bounds: Rect

The node’s absolute rectangle in logical pixels, as the last layout pass left it.

focusable: bool

Whether the node can take the keyboard focus.

disabled: bool

Whether the node is disabled.

focused: bool

Whether the node holds the keyboard focus.

pressable: bool

Whether a press on the node runs a handler, so the backend can offer the press action.
