How to generate mouse clicks to the Operating System?

Shane Brennan — Thu, 13 Sep 2007 02:21:47 -0400

I am writing a program which tracks a laser light that is
shined onto a wall. The code is able to track the laser
fine, and I am able to recognize when the user "clicks" (by
turning the laser off and on real quick). However, I do not
know how to transmit this click information to the Operating
System.

What I am wondering is, is there a MATLAB function or some
other method I can use to generate a mouse click?

There is no Matlab function for it. There might be an
ActiveX control (maybe), or dll function you could use.
If you are using Windows, this page might be useful:

I found a different page that indicated that simulating a
right click might be relatively difficult:

% create a robot
import java.awt.*;
import java.awt.event.*;
rob=Robot;
rob.mousePress(InputEvent.BUTTON1_MASK)%change button here
%may want a pause here
rob.mouseRelease(InputEvent.BUTTON1_MASK)%change button here

% to see more robot options
methodsview(rob);

I learned how to do this when I wanted to write a matlab
program to draw lines in linerider.

this site has more information about the robot

<SNIP to weak to press a button...

one of the solutions was outlined in this reply, which
shows how to simulate mouse moves/clicks...

items...My question: is it possible to do this right click
of the mouse by writing a M-Code in matlab...and thanks in
