1. ListView Question
What's the difference between,
ok=sendMessage( ListView1, LVM_SETCOLUMNWIDTH, 1,124)
and
setColumn(ListView1,1 124 )

Hello everybody,
I have 2 small questions here.
if I go:
for x=1 to 10 do
VOID &=addLVItem(LV,0,sprintf("%d",x))
end for
I get in Listview column 1:
10
9
8
7
6
5
4
3
2
1
1.) Is there a way to reverse the order (1 at the top; 10 at the bottom) without
having to hit the headings tab?
2.) Is there a way to put just the number in without using sprintf?
VOID &=addLVItem(LV,0,x))?
TIA
Don Cole

for x=10 to 1 by -1 do

probably not.

Thank you c.k.lester,
1.) I thought of that but thought I might mess other things up. I suppose not.
2.) addLVItem must use text (I guess).
Thanks,

From Win32lib docs:
[func]
setLVInsert (integer pFlag )
Sets the default position for ListView inserts.
Returns: The flag setting before this change.
Category: ListView Control
If pFLag is zero, addLVItem() adds new items to the top of the list, else new
items are added at the end. The default is to add items to the top of lists.
Example:
integer lvInsert
-- Make listviews add to end of lists.
lvInsert = setLVInsert( 1 )

Yes. There are two ways. The first is to call ...
atom OldVal
OldVal = setLVInsert(1)
Then from now on, all addLVItem calls will add to the end of the list.
The second is to call addLVItem like this ...
VOID &= adLVItem( {LV, -1}, 0, x)
The -1 here means add to end of list. You can have other positive numbers here
to add at other positions too.

There is a bug in the code. It is meant to be able to do this but the signature
is wrong.
> Replace ...
global function addLVItem(object id, atom iIcon, sequence text )
> With ...
global function addLVItem(object id, atom iIcon, object text )
And then you can say things like
for x = 1 to 10 do
VOID &= addLVItem({LV,-1},0,x))
end for

Thanks Judith and Derek,
That's exactly what I was looking for on both counts.
Both meaning, Judith and Dereck.
And both meaning, Derek's explination of two different problems.
Just one more question. In my code I only have one listView and Judith's code
works perfectly on that. But supposen' I had multiple listViews how would
lvInsert = setLVInsert( 1 )
know which listView to apply itself to?

It has a global effect. It effects all listviews. That is why you can use the
syntax
addLVItem( { lv, -1}, ... )
Also, one could code ...
-- Set effect on
temp = setLVInsert( 1 )
addLVItem ( ... )
-- Revert to previous setting.
temp = setLVInsert( temp )

In the various mods I made and submitted to Derek, setLVinsert() can act
locally (ie each ListView has its own flag, and you can act on either the
local or global one). Perhaps this will make it to the next official lib.
