NAME

SDL::Cursor -- Mouse cursor structure

CATEGORY

Core, Mouse, Structure

SYNOPSIS

 my $cursor = SDL::Cursor->new(
     \@data,
     \@mask,
     $width,
     $height,
     $hotspot_left,
     $hotspot_top );

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

DESCRIPTION

the SDL::Cursor module handles mouse cursors, and provide the developer to use custom made cursors. Note that the cursors can only be in black and white.

METHODS

new

Create a cursor using the specified data and mask (in MSB format). The cursor width must be a multiple of 8 bits.

The cursor is created in black and white according to the following:

 Data / Mask   Resulting pixel on screen
    0 / 1      White
    1 / 1      Black
    0 / 0      Transparent
    1 / 0      Inverted color if possible, black if not.

Cursors created with this function must be freed with SDL_FreeCursor.

If you want to have color cursor, then this function is not for you; instead, you must hide normal system cursor with SDL::Cursor-new> and in your main loop, when you draw graphics, also draw a SDL::Surface at the location of the mouse cursor.

Example:

 use SDL;
 use SDL::Cursor;
 use SDL::Mouse;
 use SDL::Video;
 
 SDL::init(SDL_INIT_VIDEO);
 SDL::Video::set_video_mode( 640, 480, 16, SDL_SWSURFACE);
 
 my @data = (
     0b00000000,
     0b00111100,
     0b01111110,
     0b01111110,
     0b01111110,
     0b01111110,
     0b00111100,
     0b00000000
 );

 my @mask = (
     0b00111100,
     0b01111110,
     0b11100111,
     0b11000011,
     0b11000011,
     0b11100111,
     0b01111110,
     0b00111100
 );

 my $cursor = SDL::Cursor->new( \@data, \@mask, 8, 8, 0, 0 );
 
 sleep(1);
 SDL::Mouse::set_cursor($cursor);
 
 sleep(5);
