Integrate branch of IAccessible2
in sc/source/ui/navipi/navipi.cxx with
+ case FID_KILLEDITVIEW:
+ aLbEntries.ObjectFresh( SC_CONTENT_OLEOBJECT );
+ aLbEntries.ObjectFresh( SC_CONTENT_DRAWING );
+ aLbEntries.ObjectFresh( SC_CONTENT_GRAPHIC );
+ break;
even though we already have a handler of
case SfxHintId::ScDrawChanged:
m_xLbEntries->Refresh( ScContentId::GRAPHIC );
m_xLbEntries->Refresh( ScContentId::OLEOBJECT );
m_xLbEntries->Refresh( ScContentId::DRAWING );
break;
and those "Refresh" as opposed to "ObjectFresh" try not to clear and refill the
navigator unless content has changed.
and that ObjectFresh seems to really center on the use of "sKeyString" which is
only set by ScContentTree::KeyInputHdl (in that same commit) if space is used
to select an entry with the comment "Make KEY_SPACE has same function as
DoubleClick".
I suspect ObjectFresh is a cut and paste job from Refresh that just wants to
keep the same item selected (and expanded) in the navigator that was selected
by the user before any content change that might cause the navigator to refill</pre>
