NAME

       Layout::Manager::Grid - Simple grid-based layout manager.

DESCRIPTION

       Layout::Manager::Grid is a layout manager places components into evenly divided cells.

       When you instantiate a Grid manager, you must supply it with a count of how many rows and
       columns it will have.  For example, a Grid with 1 column and 2 rows would look like:

         +--------------------------------+
         |                                |
         |           component 1          |
         |                                |
         +--------------------------------+
         |                                |
         |           component 2          |
         |                                |
         +--------------------------------+

       The container is divided into as many <rows> * <columns> cells, with each taking up an
       equal amount of space.  A grid with 3 columns and 2 rows would create 6 cells that consume
       33% of the width and 50% of the height.

       Components are placed by specifying the cell they reside in via the row and column number.

         $container->add_component($comp, { row => 0, column => 3 });

         $container->add_component($comp, { row => 0, column => 2, height => 2 });

       Optionally, you may choose to override the default "width" or "height" of 1.  Setting it
       to a something else will cause the component to consume that many rows or columns worth of
       space.

       Grid is similar to Java's GridLayout
       <http://java.sun.com/docs/books/tutorial/uiswing/layout/grid.html>.

SYNOPSIS

         $cont->add_component($comp1, { row => 0, column => 1 });
         $cont->add_component($comp2, { row => 0, column => 2 });

         my $lm = Layout::Manager::Grid->new(rows => 1, columns => 2);
         $lm->do_layout($con);

   DYNAMIC SIZING
       If the container that the Grid is manging does not have one or both of it's dimensions
       set, Grid will compute the appropriate sizes.  The simple way for me to avoid writing a
       long explanation is to say it works similar to HTML tables.  Rows will become as big as
       their biggest consituent, as will columns.  It is common to add a Grid-managed component
       to a scene with only one of it's dimensions set.

ATTRIBUTES

   columns
       The number of columns in this Grid.

   rows
       The number of rows in this Grid.

METHODS

   do_layout
       Size and position the components in this layout.
