示例1: SDL_WarpMouse
void SDL_WarpMouse (Uint16 x, Uint16 y)
{
SDL_VideoDevice *video = current_video;
SDL_VideoDevice *this = current_video;
if ( !video || !SDL_PublicSurface ) {
SDL_SetError("A video mode must be set before warping mouse");
return;
}
/* If we have an offset video mode, offset the mouse coordinates */
if (this->screen->pitch == 0) {
x += this->screen->offset / this->screen->format->BytesPerPixel;
y += this->screen->offset;
} else {
x += (this->screen->offset % this->screen->pitch) /
this->screen->format->BytesPerPixel;
y += (this->screen->offset / this->screen->pitch);
}
/* This generates a mouse motion event */
if ( video->WarpWMCursor ) {
video->WarpWMCursor(this, x, y);
} else {
SDL_PrivateMouseMotion(0, 0, x, y);
}
