NAME

SDL::Event - a SDL perl extension

SYNOPSIS

  use SDL::Event;
  my $event = new SDL::Event;             # create a new event
  while ($event->wait()) {
         my $type = $event->type();      # get event type
         # ... handle event
         exit if $type == SDL_QUIT;
  }
 
 

DESCRIPTION

"SDL::Event" offers an object-oriented approach to SDL events. By creating an instance of SDL::Event via new() you can wait for events, and then determine the type of the event and take an appropriate action.

EXAMPLE

Here is an example of a simple event handler loop routine. See also SDL::App::loop.

        sub loop {
                my ($self,$href) = @_;
                my $event = new SDL::Event;
                while ( $event->wait() ) {
                        # ... insert here your event handling like:
                        if ( ref($$href{$event->type()}) eq "CODE" ) {
                                &{$$href{$event->type()}}($event);
                                $self->sync();
                        }
                }
        }
