/** serves a single purpose - let ZoomText read the drawers ...
|
|
|
|
Strange enough, ZoomText does not read the drawers when they get the focus (in none of the combinations
|
|
of AccessibleRoles I tried), except when it does have an AccessibleChild with the role LABEL. To "inject"
|
|
such a child into the A11Y hierarchy, we use this window here.
|
|
|
|
(We could also inject the A11Y component on the A11Y level only, but this would mean additional code. With
|
|
this approach here, VCL/toolkit will take care of creating and maintaining the A11Y component for us.)
