| 11 The following nsIAccessible 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. | |
