IAccessible interface
Exposes methods and properties that make a user interface element and its children accessible to client applications.
When to implement
Servers implement this interface on controls to make them accessible to client applications.
Members
The IAccessible interface inherits from the IDispatch interface. IAccessible also has these types of members:
Methods
The IAccessible interface has these methods.
| Method | Description |
|---|---|
| accDoDefaultAction |
Performs the specified object's default action. Not all objects have a default action. |
| accHitTest |
Retrieves the child element or child object at a given point on the screen. All visual objects support this method. |
| accLocation |
Retrieves the specified object's current screen location. All visual objects support this method. |
| accNavigate |
Note The accNavigate
method is deprecated and should not be used. Clients should use other methods and properties such as AccessibleChildren, get_accChild, get_accParent, and IEnumVARIANT.
Traverses to another user interface element within a container and retrieves the object. All visual objects support this method. |
