Code: Select all
text FindNeighbours(7, 5);
function FindNeighbours($pos=1, $range=1) {
$items = listpane(, , , <crlf>);
$count = gettoken($items, "count", <crlf>);
$firstPos = ($pos - $range < 1) ? 1 : $pos - $range;
$lastPos = ($pos + $range > $count) ? $count : $pos + $range;
return gettoken(gettoken($items, $firstPos, <crlf>, , 2), $lastPos - $firstPos + 1, <crlf>, , 1);
}
Good idea.tiago wrote:Trying to optimize my navigational capabilities I see it would be very useful to be able to retrieve an item's path by its position in list. More to the point, i'm interested in an item's immediate neighbors. This would save heavy and clumsy full list retrieval. Itematpos() sounded a natural place for it, but it's coordinate driven. Get() enhancement, please...?
Code: Select all
+ SC get("item") enhanced: Added an optional parameter to pass the position
of the item in the list (the first position is "1"). If missing the
focused item is returned.
Syntax: get("Item", [pane=a], [pos])
Examples:
echo get("item", , 4); //item at position 4
Also works as variable:
echo <get item 4>; //note the 2 spaces! the "pane" parameter is missing
