Date: Sat, 06 Dec 2008 15:27:00 +0100 From: Couriersud Subject: SDL: Relative mouse movements The patch below will reenable processing of relative mouse movements. The DirectFB drivers generates those in "grabbed" mode. These ensure, that even in fullscreen mode relative movements are reported. SDLMAME depends on this for games with trackballs. Looking at the code I ask myself whether relative movements should be handled in the drivers (x11, directfb). Both x11 and directfb are able to report relative movements. This would leave it to the driver to use the most appropriate method for relative movements when at the border of a fullscreen window or being "grabbed".
