How to warp the mouse pointer position

Leandra Vicci — Fri, 02 Jan 2009 13:42:02 -0500

I wish to snap the mouse pointer to the exact coordinates of a known point in the active axes. X Windows has a function for such purposes, but I can't find an equivalent Matlab graphics function. Does one exist? If not, are there primitives I could use to write one? The axes CurrentPoint, CurrentPoint.x, and CurrentPoint.y properties are read-only, so I can't just set them.

You can use the 'PointerLocation' property of the root (0), in conjunction with figure position and axes position.

YES! It works perfectly. Thanks, Jiro.
