How can I set the mouse position?

Question

I need to set the position of the mouse on the screen. In some other similar question, it was suggested to use CGDisplayMoveCursorToPoint(CGDirectDisplayID display, CG

Answer 1

Here's a way to do it:

// coordinate at (10,10) on the screen
CGPoint pt;
pt.x = 10;
pt.y = 10;

CGEventRef moveEvent = CGEventCreateMouseEvent(
    NULL,               // NULL to create a new event
    kCGEventMouseMoved, // what type of event (move)
    pt,                 // screen coordinate for the event
    kCGMouseButtonLeft  // irrelevant for a move event
);

// post the event and cleanup
CGEventPost(kCGSessionEventTap, moveEvent);
CFRelease(moveEvent);

This will move the cursor to point (10,10) on screen (the upper left, next to the Apple menu).
