问题
Is there a simple way to use pygame to switch to an OS-defined cursor? For example, switching to the windows loading circle or apple beach-ball when loading, or changing to arrows when hovering over a draggable object?
Pygame provides the cursor module for loading a bitmap to replace the cursor, but I'd like to defer to the OS-defined cursors instead.
