Expand description
The type of an accessibility node.
The majority of these roles come from the ARIA specification. Reference the latest draft for proper usage.
Like the AccessKit schema as a whole, this list is largely taken
from Chromium. However, unlike Chromium’s alphabetized list, this list
is ordered roughly by expected usage frequency (with the notable exception
of Role::Unknown
). This is more efficient in serialization formats
where integers use a variable-length encoding.
Variants§
Unknown = 0
InlineTextBox = 1
Cell = 2
Label = 3
Image = 4
Link = 5
Row = 6
ListItem = 7
ListMarker = 8
Contains the bullet, number, or other marker for a list item.
TreeItem = 9
ListBoxOption = 10
MenuItem = 11
MenuListOption = 12
Paragraph = 13
GenericContainer = 14
A generic container that should be ignored by assistive technologies
and filtered out of platform accessibility trees. Equivalent to the ARIA
none
or presentation
role, or to an HTML div
with no role.

ListGrid = 184
Behaves similar to an ARIA grid but is primarily used by Chromium’s
TableView
and its subclasses, so they can be exposed correctly
on certain platforms.
Terminal = 185
This is just like a multi-line document, but signals that assistive technologies should implement behavior specific to a VT-100-style terminal.
