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.
Creates a new cursor. The <C>-data</C> and <C>-mask</C> parameters should be both black and white pictures. The height and width of these surfaces should be a multiple of 8. The <C>-x</C> and <C>-y</C> are the coordinates of the cursor 'hot spot'.
+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. -
Set the position of the SDL::Cursor given as first parameter . -the new postion is set to <C>x</C>, <C>y</C> coordinates in the application window. -SDL::warp trigger a new mouse motion event. -It doesn't returns anything.
+ +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; -
Set the SDL::Cursor given as first parameter to the active cursor.
+ SDL::init(SDL_INIT_VIDEO); + SDL::Video::set_video_mode( 640, 480, 16, SDL_SWSURFACE); -When used statically <C>SDL::Cursor::get()</C>, it will return the instance of the current cursor in use. Called as a method, it will return itself.
-This method can be useful if you are dealing with several cursors.
