11 : The following accessible states aren't translated, just ignored:
12 : STATE_READONLY: Supported indirectly via EXT_STATE_EDITABLE
13 : STATE_HOTTRACKED: No ATK equivalent. No known use case.
14 : The nsIAccessible state is not currently supported.
15 : STATE_FLOATING: No ATK equivalent. No known use case.
16 : The nsIAccessible state is not currently supported.
17 : STATE_MOVEABLE: No ATK equivalent. No known use case.
18 : The nsIAccessible state is not currently supported.
19 : STATE_SELFVOICING: No ATK equivalent -- the object has self-TTS.
20 : The nsIAccessible state is not currently supported.
21 : STATE_LINKED: The object is formatted as a hyperlink. Supported via ATK_ROLE_LINK.
22 : STATE_EXTSELECTABLE: Indicates that an object extends its selection.
23 : This is supported via STATE_MULTISELECTABLE.
24 : STATE_PROTECTED: The object is a password-protected edit control.
25 : Supported via ATK_ROLE_PASSWORD_TEXT
26 : STATE_PINNED: The object is pinned, usually indicating it is fixed in
27 : place and has permanence. No ATK equivalent. The
28 : accessible state is not currently supported.
29 :
30 : The following ATK states are not supported:
31 : ATK_STATE_ARMED: No clear use case, used briefly when button is activated
32 : ATK_STATE_HAS_TOOLTIP: No clear use case, no IA2 equivalent
33 : ATK_STATE_ICONIFIED: Mozilla does not have elements which are collapsable into icons
34 : ATK_STATE_TRUNCATED: No clear use case. Indicates that an object's onscreen content is truncated,
35 : e.g. a text value in a spreadsheet cell. No IA2 state.
