NAME

       SDL_WasInit - Check which subsystems are initialized

SYNOPSIS

       #include "SDL.h"

       Uint32 SDL_WasInit(Uint32 flags);

DESCRIPTION

       SDL_WasInit  allows you to see which SDL subsytems have been initialized. flags is a bitwise OR'd combination of the subsystems you wish to
       check (see SDL_Init for a list of subsystem flags).

RETURN VALUE

       SDL_WasInit returns a bitwised OR'd combination of the initialized subsystems.

EXAMPLES

       /* Here are several ways you can use SDL_WasInit() */

       /* Get init data on all the subsystems */
       Uint32 subsystem_init;

       subsystem_init=SDL_WasInit(SDL_INIT_EVERYTHING);

       if(subsystem_init&SDL_INIT_VIDEO)
	 printf("Video is initialized.
       ");
       else
	 printf("Video is not initialized.
       ");

       /* Just check for one specfic subsystem */

       if(SDL_WasInit(SDL_INIT_VIDEO)!=0)
	 printf("Video is initialized.
       ");
       else
	 printf("Video is not initialized.
       ");

       /* Check for two subsystems */

       Uint32 subsystem_mask=SDL_INIT_VIDEO|SDL_INIT_AUDIO;

       if(SDL_WasInit(subsystem_mask)==subsystem_mask)
	 printf("Video and Audio initialized.
       ");
       else
	 printf("Video and Audio not initialized.
       ");

NAME

       SDL::Mouse - SDL Bindings for the Mouse device

CATEGORY

       Core, Mouse

CONSTANTS

       The constants for SDL::Mouse belong to SDL::Events/SDL::Event, under the export tag of ':state'.

METHODS

   warp_mouse
	SDL::Mouse::warp_mouse( $x, $y );

       Set the position of the mouse cursor (generates a mouse motion event).  Even if the mouse is warped to where it currently is, a mouse
       motion event is generated.

   set_cursor
	SDL::Mouse::set_cursor( $cursor_object );

       Sets the currently active cursor to the specified one.  See SDL::Cursor for details on cursor objects.  If the cursor is currently visible,
       the change will be immediately represented on the display.  "set_cursor()" can be used to force cursor redraw, if this is desired for any
       reason.

   get_cursor
	my $cursor_object = SDL::Mouse::get_cursor;

       Gets the currently active mouse cursor.

   show_cursor
	my $return = SDL::Mouse::show_cursor( $state );

       Toggle whether or not the cursor is shown on the screen.  Passing "SDL_ENABLE" displays the cursor and passing "SDL_DISABLE" hides it.  The
       current state of the mouse cursor can be queried by passing "SDL_QUERY", either "SDL_DISABLE" or "SDL_ENABLE" will be returned.

	use SDL;
	use SDL::Mouse;
	use SDL::Video;
	use SDL::Events ':state'; #For the constants

	SDL::init(SDL_INIT_VIDEO);
	SDL::Video::set_video_mode(640, 480, 16, SDL_SWSURFACE);

	printf("Cursor is %s
", SDL::Mouse::show_cursor(SDL_QUERY) ? 'visible' : 'not visible');

	sleep(3);

	SDL::Mouse::show_cursor(SDL_DISABLE);
	printf("Cursor is %s
", SDL::Mouse::show_cursor(SDL_QUERY) ? 'visible' : 'not visible');

	sleep(3);

	SDL::Mouse::show_cursor(SDL_ENABLE);
	printf("Cursor is %s
", SDL::Mouse::show_cursor(SDL_QUERY) ? 'visible' : 'not visible');

	sleep(3);
