       "Tickit::Widget::VBox" - distribute child widgets in a vertical column

SYNOPSIS

          use Tickit;
          use Tickit::Widget::VBox;
          use Tickit::Widget::Static;

          my $vbox = Tickit::Widget::VBox->new;

             $vbox->add(
                Tickit::Widget::Static->new(
                   text   => $position,
                   align  => "centre",
                   valign => $position,
                ),

          Tickit->new( root => $vbox )->run;

DESCRIPTION

       This subclass of Tickit::Widget::LinearBox distributes its children in a vertical column.
       Its width will be the width of the widest child, and its height will be the sum of the
       heights of all the children, plus the inter-child spacing.

STYLE

       The default style pen is used as the widget pen.

       Note that while the widget pen is mutable and changes to it will result in immediate
       redrawing, any changes made will be lost if the widget style is changed.

       The following style keys are used:

       spacing => INT
           The number of lines of spacing between children
