SDL::Event(3) User Contributed Perl Documentation SDL::Event(3)NAMESDL::Event - a SDL perl extension
SYNOPSIS
use SDL::Event;
my $event = new SDL::Event; # create a new event
$event->pump(); # pump all events from SDL Event Queue
$event->poll(); # Get the top one from the queue
while ($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();
}
}
}
