There is base class B, and two derived classes D1 and D2 derived from Base. Base class B, have two data members ( public or protected or private or if any).

html::display::common
HTML::Display::Common(3pm) User Contributed Perl Documentation HTML::Display::Common(3pm) 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' ); AUTHOR
