SDL_sim_cursor

This small library emulates the SDL_*Cursor family of functions, useful if your driver doesnt support cursors (such as small embedded linux handhelds).

This uses the GNOME Aidwaita 24x24 cursors which have been converted to 4bit by medeirosT.

Most of the code is from SDL2, from the file src/events/SDL_mouse.c.

Usage

Place SDL_sim_cursor.h into your source tree.

/* Add the following include into a header that includes SDL.h */
#include "SDL_sim_cursor.h"

/* And in atleast 1 c/cpp file that includes the header you placed the above line in, add at the top of the file */
#define SDL_SIM_CURSOR_COMPILE 1

/* After SDL_Init() add the following: */
SDL_SIM_MouseInit();

/* And before SDL_Quit() */
SDL_SIM_MouseQuit();

If the program uses SDL_Surfaces / SDL_BlitSurface use the following:

/* You need to find the call to the SDL_BlitSurface that draws to the main window surface, call this to the surface. */
SDL_SIM_BlitCursor(window_surface);

If the program uses SDL_Renderer you need to use the following:

/* Assign the renderer to the SDL_sim_cursor library */
SDL_SIM_Set_Renderer(current_renderer);

/* Find SDL_RenderPresent and do */
SDL_SIM_RenderCursor(NULL);
