-SDL Perl Windows Status +Once in a while .... (set_event_filter)

-Hello windows users,

Here is a simple picture explaining the status of SDL Perl on windows. I am hoping this changes. I know that Alias is interested in this too.

Here are steps needed to solve this:
  1. Find out exactly what gcc flags are needed to make this work with strawberry's toolchain
  2. Get the deps here. Put the deps in C:/strawberry/c.
  3. Try to make a Module::Build script work for win32 and win64 (There are differences apparently)
  4. Try and emulate this in our current build system ( make/lib/Build.pm, and make/lib/Build/Win32.pm )
  5. Give me a shout on RT or sdl-devel@perl.org ( even if you just make it to 3.)
  6. Enjoy SDL and lots of ++ from Alias, CSJewell and SDL_perl devs.
There easy as pie

+Once in a while
+Things just work!
+
+

+
+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,
--yapgh
