Scroll to focused item on Windows Explorer left pane

[ssimop]

Supposed that a folder is selected/focused on Windows Explorer left pane (child id 100). The following macro moves the mouse pointer to this item. No problem up to now. The question rises when - for some reason - the item is not visible, although focused. How should I scroll to it? I understand that SendMessage with LVM_ENSUREVISIBLE does not work in this case inasmuch it is an outline object. Any advice is welcome.

Function tempf10

Code:

int w=win("" "ExploreWClass")
int c=id(100 w) ;;outline
act c
Acc a=acc()
a.Mouse(0)
a.Select(SELFLAG_TAKEFOCUS|SELFLAG_TAKESELECTION)
