mouse coordinates
May 26th, 2006, 6:25pm  
I want to use processing to do this:  http://www.we-make-money-not-art.com/archives/008513.php

I wanna drop a mouse ontop of a moving surface and use the changing coordinates to make visualisations.

From the examples I have seen i can only get coordinates if the mouse cursur is within the java applet window.  How can i get mouse coordinates in the case when the mouse would move waaaaaay off of the screen.  I.e. the limitation of the coordinates would not be mearly 768x1024 pixels but infinite.

Thanks in advance.  Joost

If this is for a sketch you want to run on your own system or similar, yuo can use the java Robot class to set the mouse x/y position, and then measure the changes in position from that fixed position, giving you infinite mouse movement.

However this will not work in an online applet unless you sign the applet, and the user accepts it, since you could use it for evil...

yeah that is what I am wanting to do, run it locally on my machine only.

I have been unsuccessfully trying to find further info on the "java Robot class", I am still new with Processing, could you point me in the right direction where I might be able to find an example or some other kind of reference material?

Thanks

Heh, heh.

   robot.keyPress(keys1[i]);
   robot.keyRelease(keys1[i]);
 }
}

Non malicious, windows only. I tried to get it open the command prompt and write rm * or something but the synchronisation and focus is pretty hard to keep control of.
