Hi, I'm having an issue which with warping the mouse pointer on Mac OS X that is generally expected, but behaves differently than on other platforms.
That is, when you warp the mouse pointer using either of the warp functions (GraphicsWindowCarbon uses CGDisplayMoveCursorToPoint), all input is frozen for 0.25 seconds. When trying to implement a mouse look style mouse movement, the normal method is to move the mouse pointer back to the center of the screen even frame on other platforms, but doing this blocks all input in OS X for a quarter second unless I call CGSetLocalEventsSuppressionInterval(0); The other method is to disassociate the mouse pointer position from the mouse movement, but that solution won't work with the current osx window classes because they track the mouse position, not its movement. I was going to submit a change adding the above line to GraphicsWindowCarbon, and possible the Cocoa version, but it appears that this function is deprecated in 10.6 in favor of CGEventSourceSetLocalEventsSuppressionInterval(...); So, to conclude, I have two points to this post. 1. I think we should make this the default behavior so it will work the same across platforms, unless there is another solution 2. I don't know how to implement this using the other function because I'm not an expert on event sources, and I haven't really been able to make it work. Does anyone more skilled than I in this area know how to make this work or do you recommend I just use the older function for now? Thank you!
