Struct accesskit::Tree [−][src]

pub source_string_encoding: StringEncoding,
pub parent: Option<TreeId>,
pub root_scroller: Option<NodeId>,
}
Expand description
The data associated with an accessibility tree that’s global to the tree and not associated with any particular node.
Fields
id: TreeId
root: NodeId
source_string_encoding: StringEncoding
The string encoding used by the tree source. This is required
to disambiguate string indices, e.g. in Node::words
.
When the tree is serialized, the encoding specified by
the target serialization format is always used. But this way,
the tree source doesn’t have to convert string indices;
the platform adapter will do this if needed.
parent: Option<TreeId>
The ID of the tree that this tree is contained in, if any.
root_scroller: Option<NodeId>
The node that’s used as the root scroller, if any. On some platforms like Android we need to ignore accessibility scroll offsets for that node and get them from the viewport instead.
