JAVA! generate mouse events

juanctes · 12-09-2008, 03:54 PM

Hi, hope to be clear enough so someone can help me.
After a couple of hours digging i cant find a way to make a java program to generate mouse events. I found the Robot class that has the method mousemove(x,y) but I dont need the pointer to be relocated at some position in the screen.
What i need is to translate some input (from jinput, already reading a book on that) to "real" mouse movements.
for example:
if you press key 1: the mouse should go 1 unit forward.
if you press key 2: the mouse should go 2 units forward.
and so on..

the Robot.mousemove(x,y) will magically make the pointer appear at x y in the screen. besides if I see that the pointer is at (10, 10) an I relocate it at (10,9) and repeat it several times the screen will end at (10,0)...

I would like to enable an other program that is expecting mouse movements to believe that the mouse moved forward, backward, etc... like if someone actually moved the mouse. NOTHING TO DO WITH the screen!

Hope someone knows how to do this.
cheers!

So basically, you're trying to move the cursor programatically?

hi, a new lesson i learned today:

Be Forthright When Cross Posting To Other Sites.
It can be frustrating posting an elaborate answer only to later find out that someone has posted the same answer previously on another forum.

I asked the same questionat those sites in order to maximize the chances of getting a good answer:

so, basically I need to make the same effect as if the user is moving the mouse, not just relocating the pointer at some coordinates. Imagine a program that would be rolling a ball if the user is moving the mouse, here the screen coordinates doesn't help..

THANKS to guys in Javaranch.

Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent(
new MouseEvent( miComponente,MouseEvent.MOUSE_CLICKED,0,0,-1,-1,2,false ) );

in this link you'll find more. if you like spanish... other wise googling '"new MouseEvent"' would do.
