* Accessibility clients use child identifiers to specify | |
* whether they want information about a control or one of its children. | |
* Child identifiers are positive integers > 0. | |
* The identifier CHILDID_SELF (0) represents the control. | |
* When returning a child identifier to a client, you may use CHILDID_NONE | |
* to indicate that no child or control has the required information. | |
* </p><p> | |
* Note: This adapter is typically used by implementors of | |
* a custom control to provide very detailed information about | |
* the control instance to accessibility clients. | |
