No known use case. The nsIAccessible state is not currently supported. STATE_FLOATING: No ATK equivalent. No known use case. The nsIAccessible state is not currently supported. STATE_MOVEABLE: No ATK equivalent. No known use case. The nsIAccessible state is not currently supported. STATE_SELFVOICING: No ATK equivalent -- the object has self-TTS. The nsIAccessible state is not currently supported. STATE_LINKED: The object is formatted as a hyperlink. Supported via ATK_ROLE_LINK. STATE_EXTSELECTABLE: Indicates that an object extends its selection. This is supported via STATE_MULTISELECTABLE. STATE_PROTECTED: The object is a password-protected edit control. Supported via ATK_ROLE_PASSWORD_TEXT STATE_HASPOPUP: Object displays a pop-up menu or window when invoked. No ATK equivalent. The nsIAccessible state is not currently supported. The following ATK states are not supported: ATK_STATE_ARMED: No clear use case, used briefly when button is activated ATK_STATE_HAS_TOOLTIP: No clear use case, no IA2 equivalent ATK_STATE_ICONIFIED: Mozilla does not have elements which are collapsable into icons ATK_STATE_TRUNCATED: No clear use case. Indicates that an object's onscreen content is truncated, e.g. a text value in a spreadsheet cell.
