1.14 +The following nsIAccessible states aren't translated, just ignored:
1.15 + STATE_READONLY: Supported indirectly via EXT_STATE_EDITABLE
1.16 + STATE_HOTTRACKED: No ATK equivalent. No known use case.
1.17 + The nsIAccessible state is not currently supported.
1.18 + STATE_FLOATING: No ATK equivalent. No known use case.
1.19 + The nsIAccessible state is not currently supported.
1.20 + STATE_MOVEABLE: No ATK equivalent. No known use case.
1.21 + The nsIAccessible state is not currently supported.
1.22 + STATE_SELFVOICING: No ATK equivalent -- the object has self-TTS.
1.23 + The nsIAccessible state is not currently supported.
1.24 + STATE_LINKED: The object is formatted as a hyperlink. Supported via ATK_ROLE_LINK.
1.25 + STATE_EXTSELECTABLE: Indicates that an object extends its selection.
1.26 + This is supported via STATE_MULTISELECTABLE.
1.27 + STATE_PROTECTED: The object is a password-protected edit control.
1.28 + Supported via ATK_ROLE_PASSWORD_TEXT
1.29 + STATE_HASPOPUP: Object displays a pop-up menu or window when invoked.
1.30 + No ATK equivalent. The nsIAccessible state is not currently supported.
1.31 + STATE_PINNED: The object is pinned, usually indicating it is fixed in place and has permanence.
1.32 + No ATK equivalent. The nsIAccessible state is not currently supported.
1.33 +
1.34 +The following ATK states are not supported:
1.35 + ATK_STATE_ARMED: No clear use case, used briefly when button is activated
1.36 + ATK_STATE_HAS_TOOLTIP: No clear use case, no IA2 equivalent
1.37 + ATK_STATE_ICONIFIED: Mozilla does not have elements which are collapsable into icons
1.38 + ATK_STATE_TRUNCATED: No clear use case. Indicates that an object's onscreen content is truncated,
1.39 + e.g. a text value in a spreadsheet cell. No IA2 state.
