Subject: [SDL] bug: SDL_WarpMouse does not change MouseState

First call of SDL_WarpMouse() wraps mouse cursor but does not change
mouse position returned by SDL_GetMouseState(). This happends when mouse
starts outside window. The position remains [0, 0].                 

The second call of SDL_WarpMouse() updates mouse position to right
values.

I attached test program which wraps mouse and 10 times prints mouse
position. Start with mouse out of window and don't move it. Positions
will be [0, 0] instead of [320, 240].

System Information:

If your mouse cursor is not within the SDL frame and you warp the mouse, you
get an enter notify, not a motion notify.
Therefore, SDL does not update its internal mouse state.

What's about calling SDL_PrivateMouseMotion even when getting an EnterNotify?

Johannes

I'd like to get this fixed for SDL 1.2.10 release, if possible.
Comment 4 Sam Lantinga 2006-05-09 03:20:38 UTC 
This is fixed in Subversion.
