$l->SetItemState( 3,    0,     wxLIST_STATE_SELECTED );
                  ^     ^      ^
                  item  state  mask

theidea behind state and mask is that you specify in the mask
the flags you want to change
( e.g. wxLIST_STATE_SELECTED|wxLIST_STATE_FOCUSED ) and list
in the state the states you want to set asn don't list the
states you want to clear. So for deselecting the mask contains
_SELOCTED and the state contains nothing, since you want to
clear the selection. I hope you undertand this
confuse explanation...

BTW, the docs for wxLC::GetNextItem use wxLIST_NEXT_ALL to search
for the next selected item.

Strange, doesn't happen for me.

> if i pass "-1" as item, it doesn't find the next (first) selected item...
Possibily because it looks like BELOW means 'in the same column'
( at least for icon views )
and a -1 item isn't in any column, so there can't be any item in the
same column, right?

Are you using the wxLC in icon or report mode? Doesn't
wxLIST_NEXT_ALL work for you? What are you exactly trying to achieve?

As usual: minimal patch against listctrl ( or another ) example
showing the problem welcome.

yes, i didn't understand the wxwindows documentation but i understand
yours... thanks...

but i found out a better way to solve my problem...
i use now "GetNextItem" with "wxLIST_NEXT_BELOW" but it dosn't work the way
i expect it...

if i pass the last selected item to it, i think it should return "-1"... but
it returns the item i passed to GetNextItem...
if i pass "-1" as item, it doesn't find the next (first) selected item...

any hints/ideas?
