Relations List
MSAA Relation | Description | Gecko Relation |
---|---|---|
NAVRELATION_CONTROLLED_BY = 0x1000
| Some attribute of this object is affected by a target object. | RELATION_CONTROLLED_BY |
NAVRELATION_CONTROLLER_FOR = 0x1001
| This object is interactive and controls some attribute of a target object. | RELATION_CONTROLLER_FOR |
NAVRELATION_DESCRIBED_BY = 0x100e
| This object is described by the target object. | RELATION_DESCRIBED_BY |
NAVRELATION_DESCRIPTION_FOR = 0x100f
| This object is describes the target object. | RELATION_DESCRIPTION_FOR |
NAVRELATION_EMBEDDED_BY= 0x100a
| This object is embedded by a target object. | RELATION_EMBEDDED_BY |
NAVRELATION_EMBEDS = 0x1009
| This object embeds a target object. This relation can be used on the OBJID_CLIENT accessible for a top level window to show where the content areas are. | RELATION_EMBEDS |
NAVRELATION_FLOWS_FROM = 0x1007
| Content flows to this object from a target object. | RELATION_FLOWS_FROM |
NAVRELATION_FLOWS_TO = 0x1006
| Content flows from this object to a target object. | RELATION_FLOWS_TO |
NAVRELATION_LABEL_FOR = 0x1002
| This object is label for a target object. | RELATION_LABEL_FOR |
NAVRELATION_LABELLED_BY = 0x1003
| This object is labelled by a target object. | RELATION_LABELED_BY |
NAVRELATION_MEMBER_OF = 0x1004
| This object is a member of a group of one or more objects. When there is more than one object in the group each member may have one and the same target, e.g. a grouping object. It is also possible that each member has multiple additional targets, e.g. one for every other member in the group. | RELATION_MEMBER_OF |
NAVRELATION_NODE_CHILD_OF = 0x1005
| This object is a child of a target object. | RELATION_NODE_CHILD_OF |
NAVRELATION_PARENT_WINDOW_OF = 0x100c
| This object is a parent window of the target object. | RELATION_PARENT_WINDOW_OF |
NAVRELATION_POPUP_FOR = 0x100b
| This object is a transient component related to the target object. When this object is activated the target object doesn't loose focus. | RELATION_POPUP_FOR |
NAVRELATION_SUBWINDOW_OF = 0x1008
| This object is a sub window of a target object. | RELATION_SUBWINDOW_OF |
NAVRELATION_DEFAULT_BUTTON = 0x100d
| This object is a sub window of a target object. | RELATION_DEFAULT_BUTTON |
NAVDIR_DOWN (not currently supported)
| Navigate to the sibling object located below the starting object. | nsIAccessible.getAccessibleBelow()
|
NAVDIR_FIRSTCHILD
| Navigate to the first child of this object. When using this flag, the lVal member of the varStart parameter must be CHILDID_SELF. | nsIAccessible.firstChild |
NAVDIR_LASTCHILD
| Navigate to the last child of this object. When using this flag, the lVal member of the varStart parameter must be CHILDID_SELF. | nsIAccessible.lastChild |
NAVDIR_LEFT (not currently supported)
| Navigate to the sibling object located to the left of the starting object. | nsIAccessible.getAccessibleToLeft()
|
NAVDIR_NEXT
| Navigate to the next logical object, generally a sibling to the starting object. | nsIAccessible.nextSibling |
NAVDIR_PREVIOUS
| Navigate to the previous logical object, generally a sibling to the starting object. | nsIAccessible.previousSibling |
NAVDIR_RIGHT (not currently supported)
| Navigate to the sibling object located to the right of the starting object. | nsIAccessible.getAccessibleToRight()
|
NAVDIR_UP (not currently supported)
| Navigate to the sibling object located above the starting object. | nsIAccessible.getAccessibleAbove()
