=head1 METHODS

=head2 new

This initiates the object.

    my $avb=Gtk2::Ex::Email::AddressVBox->new();

=cut

sub new{
	my $self={error=>undef,
			  perror=>undef,
			  errorString=>undef,
			  gui=>{
					hboxes=>{},
					},
			  };
	bless $self;
	
	return $self;
}

=head2 addHB

This adds a new HBox to the VBox. The HBox contains
the stuff for a single address.

Two option arguements are taken the first is the type to add
and the second is the address.

    #adds a new blank one
    $avd->addHB();

    #adds a new blank To one
    $avd->addHB('to');

    #adds a new blank CC one
    $avd->addHB('cc');

    #adds a new blank BCC one
    $avd->addHB('bcc');

    #adds a new blank To one set to foo@bar
    $avd->addHB('to', 'foo@bar');

	#once this is set to true, it means that a new one has been added and should not be done again
	$hbox{new}=0;

	#sets the id
	$hbox{id}=rand().rand().rand();

	#creates the first HB

=head2 getAddresses

This gets the the addresses users have entered. Any that match
'' or /^ *$/ will be ignored.

=head2 vbox

This creates the VBox that contains the widgets.

This is a array of BCC addresses.
