You're correct. That code only changes the status of the item you've
specified, but doesn't 'unselect' the currently selected item(s). I'm not
certain when I sent that to you, but in my copy of .55, I've modified setIndex
(did it on 1/26/01):
I added integers:
integer msg,
-- added for listview:
start, check, ix, count
and added an elsif clause that cycles through the listview and
deselects/selects as appropriate. It might be faster for larger listviews to
merely get the selected group of items and deselect those, then selecting your
list.
elsif window_type[id] = ListView then
if atom( index ) then
index = { index }
end if
start = 0
result = struct_LVITEM( LVIF_STATE, start, 0, 0,
LVIS_SELECTED, 0, 0, 0 )
store( result, LVITEM_stateMask, LVIS_SELECTED )
count = sendMessage( id, LVM_GETITEMCOUNT, 0, 0)
while count do
ix = getLVItemlParam( id, start )
if find( ix, index ) then
store( result, LVITEM_state, LVIS_SELECTED )
else
store( result, LVITEM_state, 0 )
end if
VOID = sendMessage( id, LVM_SETITEMSTATE, start, result )
start += 1
count -= 1
end while
-- release the structure from memory
ix = new_memset()
manage_mem( ix, result )
release_mem( ix )
return
