commit db0044242a
Author: Michael Weghorn <m.weghorn@posteo.de>
Date: Wed Sep 6 09:12:23 2023 +0200
tdf#156683 a11y: Forward when wrapped a11y context is disposing
switched from overriding `disposing()` to overriding
`disposing(const css::lang::EventObject&)` in
`OAccessibleContextWrapperHelper` in order to
make sure that the corresponding entry in the
`AccessibleEventNotifier` client map is removed and
event listeners for the wrapper get notified
(via `AccessibleEventNotifier::revokeClientNotifyDisposing`)
when the wrapped object is disposing.
As Noel points out in [1], the `disposing()`
case should probably still be overriden/handled
and make sure that the wrapped object etc. get
disposed, so disposing one object via the other
works both ways.
(If the wrapped object is disposed, so is the
wrapper. If the wrapper gets disposed, so is
the wrapped object.)
Therefore, add back `OAccessibleContextWrapper::disposing()`
and extract the logic to a separate helper method
that is called from both `disposing` variants.
