Yes, this worked.
The “trick” was to use fOutlineListView->IndexOf(tree_item); to get the
subindex, then use the subindex in the call to list_view->Select(subindex).
Not exactly intuitive, since its a 2 step process.
Ideally, a FullListSelect(index) can be added to the class API to prevent
other devs from encountering the same problem.
Thx again, now onto my next problem with BTranslationUtils when called from
many threads simultaneously (single thread access is fine) …. A topic for
another day.

Still works for me, and I don't even know what can go wrong, except maybe
the index calculation.
Here is a tested full implementation, in case you still have problems:
bool
FullListSelectItem(BOutlineListView* listview, int32 index, bool
expandIfNecessary)
{
BListItem* item = listview->FullListItemAt(index);
if (item == NULL)
return false;
if (expandIfNecessary) {
BListItem* parent = listview->Superitem(item);
while (parent) {
listview->Expand(parent);
parent = listview->Superitem(parent);
}
}
index = listview->IndexOf(item);
if (index < 0)
return false;
listview->Select(index);
return true;
}
But from what you are saying now, you already know the BListItem you want
to select and you have all the "path" expanded, so you don't need the "full
tree" index and this should be enough for you:
listview->Select(listview->IndexOf(item));
