[SDL] Re: How to move window with SDL

I tried to do it on Linux with:

int x = 0, y = 0;

  SDL_SysWMinfo info;
  SDL_VERSION(&info.version);

  if (SDL_GetWMInfo(&info) > 0 ) {
    if (info.subsystem == SDL_SYSWM_X11) {
      info.info.x11.lock_func();
      XMoveWindow(info.info.x11.display, info.info.x11.window, x, y);
      info.info.x11.unlock_func();
    }
  }

But it moved Widget within Windows instead of moving Windows.

I tried to get parent Windows, but was not able to find a suitable 
function to do that.

Rohit Singh.
