mouseDragged(MouseEvent event) { int valueX = event.getX(); int valueY = event.getY(); } getting the x and the y coordinates of the mouse seem to return a relative number example(-14, 0) instead of an absolute number(546, 873). How could I get that absolute value, and not the relative value based on the component setting the MouseMotionListener. thanks

Look up the API documentation for MouseEvent: getX() : Returns the horizontal x position of the event relative to the source component. The coordinates are not global to your monitor screen, they are in the coordinates within the component. -14 indicates that the mouse is now 14 pixels to the left of the left side of the component for which the mouseDragged() event was fired.

Hi, thanks for the quick reply. I know about the not global thing, I was just wondering if you knew of a solution.

You'll have to get the Component that launched the event (via event.getSource()), get the screen location of that component(via Component.getScreenLocation()), and add the x and y location of the event to this point. Voila! You have to x and y location of the event on the screen! -Nate
