Hey!
Uff, yes. When Germ�n and I did this project: http://ss3.gemstone.com/ss/KinematicTemplates.html, we had to fight a lot with that.
Take a look at the code.

In the package KinematicTemplates-FFI there's a class Invokator that changes the cursor position at OS level:

Invokator(class)>>apiCGWarpMouseCursorPosition: aCGPoint
��� "CGError CGWarpMouseCursorPosition(CGPoint newCursorPosition);"
��� < apicall: void 'CGWarpMouseCursorPosition' ( CGPoint )� module: 'CoreGraphics.framework'>��
��� ^ self externalCallFailed.���

And then, an example of usage:

Invokator apiCGWarpMouseCursorPosition: (CGPoint from: 30@30 ).

Tricky detail: if after evaluating that example you print World activeHand position, it will not be 30@30, so you also have to update the activeHand's position:

World activeHand position: 30@30.

Tell me if you need something else, or if this isn't really what you needed :P

Cheers,
Carla.

Hi all!

��� I'm doing a bizarre experiment where i need to change the position of the mouse to a fixed point (like make the mouse pointer to jump from where it is to a button). Does anyone have a clue about how to?
