Returns the number of children that belong to this object.
A child can provide accessibility information on its own (e.g. a child widget), or be a sub-element of this accessible object.
All objects provide this information.

Returns the 1-based index of the object child in this object's children list, or -1 if child is not a child of this object.
0 is not a possible return value.
All objects provide this information about their children.

Navigates from this object to an object that has a relationship relation to this object, and returns the respective object in target.
It is the caller's responsibility to delete *target after use.
If an object is found, target is set to point to the object, and the index of the child of target is returned. The return value is 0 if target itself is the requested object. target is set to null if this object is the target object (i.e. the requested object is a handled by this object).
If no object is found target is set to null, and the return value is -1.
The entry parameter has two different meanings:
Hierarchical and Logical relationships – if multiple objects with the requested relationship exist entry specifies which one to return. entry is 1-based, e.g. use 1 to get the first (and possibly only) object with the requested relationship.
The following code demonstrates how to use this function to navigate to the first child of an object:
Note that the Descendent
value for relation is not supported.
All objects support navigation.

Returns the current state of the object, or of the object's child if child is not 0.
