  21  * This test suite currently works by building a quite complex hierarchy of
  22  * objects in a variety of styles and then performs a limited number of tests
  23  * for the previous and next dialog group or tab items.
  24  *
  25  * The test specifically does not test all possibilities at this time since
  26  * there are several cases where the Windows behaviour is rather strange and
  27  * significant work would be required to get the Wine code to duplicate the
  28  * strangeness, especially since most are in situations that would not
  29  * normally be met.

 276  *
 277  * Tests 9-14 test descent
 278  *
 279  *   9. DS_CONTROL does not result in descending the hierarchy for Tab Next
 280  *  10. DS_CONTROL does not result in descending the hierarchy for Group Next
 281  *  11. WS_EX_CONTROLPARENT results in descending the hierarchy for Tab Next

 290  *  16. Next Group of a visible enabled non-group control wraps around to the

 309  * the WS_EX_CONTROLPARENT style and so cannot be reached from the top of
 310  * the dialog.

 315  *  27. Next Tab of an inaccessible control is as if it were accessible
