Synopsis

print 
$query->scrolling_list('name',\@list[,selected,size,'true',\%labelhash]);

Generates a scrolling list.

name

The name to assign the input to (required).

\@ list

An array reference with the list items. You can also use an anonymous array reference.

selected

The menu item(s) to be initially selected (default is that nothing is selected). This can be a single value or a reference to a list of values.

size

The number of elements to display in the list box.

'true'

Allows multiple selections.

\% labelhash

A hash reference listing labels for each list item. Default is the list text itself. (See popup_menu for an example.) Using named parameters, the syntax is:

print $query->scrolling_list(-name=>'name',
                             -values=>\@listarray,
                             -default=>selected,
                             -size=>size,
                             -multiple=>'true',
                             -labels=>\%labelhash,
                             -onChange=>function,
                             -onFocus=>function,
                             -onBlur=>function);
-onChange=> function
