-Once in a while .... (set_event_filter) +SDL Alpha 2: A sneak preview

-

-Once in a while
-Things just work!
-
+
Pretty or Ugly,
+
Code is Code
+
New or Old,
+
Code is Code
+
Fast or Slow
+
Code is Code 

+So over the past week we have been working hard to release the next Alpha for SDL-2.3. In this release we have ported SDL_Image completely, fixed false negatives in our testing suite, improved conditional building. Also we have also started to migrate the very pretty SDL_GFX library. Here is the test for it, enjoy.

-So I have been hacking for a while on SDL::Events::set_event_filter. The code below is an example usage. The magic behind this is here
-
-
 1 #!/usr/bin/perl -w
- 2 use strict;
- 3 use warnings;
- 4 use SDL v2.3; #Require the redesign branch
- 5 use SDL::Video;
- 6 use SDL::Event;
- 7 use SDL::Events;
- 8 
- 9 SDL::init(SDL_INIT_VIDEO);
-10 my $display = SDL::Video::set_video_mode(640,480,32, SDL_SWSURFACE );
-11 my  $event = SDL::Event->new();
-12 
-13 #This filters out all ActiveEvents
-14 my $filter = sub { 
-15      my ($e, $type) = ($_[0], $_[0]->type); 
-16      if($type == SDL_ACTIVEEVENT){ return 0 } 
-17      elsif($type == SDL_MOUSEBUTTONDOWN && $e->button_button == 1){ return 0 }
-18      else { return 1; }
-19       };
-20 
-21 SDL::Events::set_event_filter($filter);
-22 
-23 while(1)
-24 {
-25 
-26   SDL::Events::pump_events();
-27   if(SDL::Events::poll_event($event))
-28   {
-29 
-30   if(  $event->type == SDL_ACTIVEEVENT)
-31  {
-32  print "Hello Mouse!!!\n" if ($event->active_gain && ($event->active_state == SDL_APPMOUSEFOCUS) );
-33  print "Bye Mouse!!!\n" if (!$event->active_gain && ($event->active_state == SDL_APPMOUSEFOCUS) );
-34         }
-35   if( $event->type == SDL_MOUSEBUTTONDOWN)
-36    {
-37  my ($x, $y, $but ) = ($event->button_x, $event->button_y, $event->button_button);
-38  warn "$but CLICK!!! at $x and $y \n";
-39  }
-40 
-41       last if($event->type == SDL_QUIT);
-42   }
-43 }
-44 SDL::quit(); 
 
 
Tinker with $filter and look at perldoc lib/SDL/pods/Event.pod. 
 
Have fun,
