NAME

HTML::Display::Common - routines common to all HTML::Display subclasses

__PACKAGE__->new %ARGS

Creates a new object as a blessed hash. The passed arguments are stored within the hash. If you need to do other things in your constructor, remember to call this constructor as well : 
   package HTML::Display::WhizBang;
   use parent 'HTML::Display::Common';
 
   sub new {
     my ($class) = shift;
     my %args = @_;
     my $self = $class->SUPER::new(%args);
 
     # do stuff
 
     $self;
   };

$display->display %ARGS

This is the routine used to display the HTML to the user. It takes the following parameters : 
   html     => SCALAR containing the HTML
   file     => SCALAR containing the filename of the file to be displayed
   base     => optional base url for the HTML, so that relative links still work
 
   location    (synonymous to base)

Basic usage :

   my $html = "<html><body><h1>Hello world!</h1></body></html>";
   my $browser = HTML::Display->new();
   $browser->display( html => $html );

Location parameter :

If you fetch a page from a remote site but still want to display it to the user, the "location" parameter comes in very handy :

   my $html = '<html><body><img src="/images/hp0.gif"></body></html>';
   my $browser = HTML::Display->new();
 
   # This will display part of the Google logo
   $browser->display( html => $html, base => 'http://www.google.com' );
