=head1 NAME
Prima::ExtLists - extended functionality for list boxes
=head1 SYNOPSIS
use Prima::ExtLists;
my $vec = '';
vec( $vec, 0, 8) = 0x55;
Prima::CheckList-> new(
items => [1..10],
vector => $vec,
);
=head1 DESCRIPTION
The module is intended to be a collection of list boxes with
particular enhancements. Currently the only package is contained
is C<Prima::CheckList> class.
=head1 Prima::CheckList
Provides a list box, where each item is equipped with a check box.
The check box state can interactively be toggled by the enter key;
also the list box reacts differently by click and double click.
=head2 Properties
=over
=item button INDEX, STATE
Runtime only. Sets INDEXth button STATE to 0 or 1.
If STATE is -1, the button state is toggled.
Returns the new state of the button.
=item vector VEC
VEC is a vector scalar, where each bit corresponds to the check state
of each list box item.
See also: L<perlfunc/vec>.
=back
=head2 Methods
=over
=item clear_all_buttons
Sets all buttons to state 0
=item set_all_buttons
Sets all buttons to state 1
