NAME

       Graph::Easy::Layout::Grid - Grid management and size calculation

SYNOPSIS

	       use Graph::Easy;

	       my $graph = Graph::Easy->new();

	       my $bonn = Graph::Easy::Node->new(
		       name => 'Bonn',
	       );
	       my $berlin = Graph::Easy::Node->new(
		       name => 'Berlin',
	       );

	       $graph->add_edge ($bonn, $berlin);

	       $graph->layout();

	       print $graph->as_ascii( );

	       # prints:

	       # +------+     +--------+
	       # | Bonn | --> | Berlin |
	       # +------+     +--------+

DESCRIPTION

       "Graph::Easy::Layout::Grid" contains routines that calculate cell sizes on the grid, which is necessary for ASCII, boxart and SVG output.

       Used automatically by Graph::Easy.

EXPORT

       Exports nothing.

SEE ALSO

       Graph::Easy.

METHODS

       This module injects the following methods into Graph::Easy:

   _prepare_layout()
	       my ($rows,$cols,$max_x,$max_y, @V) = $graph->_prepare_layout();

       Returns two hashes ($rows and $cols), containing the columns and rows of the layout with their nec. sizes (in chars) plus the maximum
       framebuffer size nec. for this layout. Also returns reference of a list of all cells to be rendered.

NAME

       Graph::Easy::Group::Cell - A cell in a group

SYNOPSIS

	       use Graph::Easy;

	       my $ssl = Graph::Easy::Edge->new( );

	       $ssl->set_attributes(
		       label => 'encrypted connection',
		       style => '-->',
		       color => 'red',
	       );

	       $graph = Graph::Easy->new();

	       $graph->add_edge('source', 'destination', $ssl);

	       print $graph->as_ascii();

DESCRIPTION

       A "Graph::Easy::Group::Cell" represents a cell of a group.

       Group cells can have a background and, if they are on the outside, a border.

       There should be no need to use this package directly.

METHODS

   error()
	       $last_error = $group->error();

	       $group->error($error);		       # set new messags
	       $group->error('');		       # clear error

       Returns the last error message, or '' for no error.

   as_ascii()
	       my $ascii = $cell->as_ascii();

       Returns the cell as a little ascii representation.

   as_html()
	       my $html = $cell->as_html($tag,$id);

       Returns the cell as HTML code.

   label()
	       my $label = $cell->label();

       Returns the name (also known as 'label') of the cell.

   class()
	       my $class = $cell->class();

       Returns the classname(s) of this cell, like:

	       group_cities gr gb

       for a cell with a bottom (gb) and right (gr) border in the class "cities".

EXPORT

       None.
