1. Run the app (attached).
The app shows whatever mouse events happen on the two colored squares. Move or click mouse and you sill see.
2. Push "test" button
in the output I see:
BLUE MOVED (100, 150) ...
BLUE PRESSED (110, 160) ...
3. If not - repeat a few times

Here is the robot code:
                                    Robot robot = com.sun.glass.ui.Application.GetApplication().createRobot();;
                                    robot.mouseMove(100, 150);
                                    robot.mousePress(1);
                                    robot.mouseRelease(1);
                                    robot.mouseMove(110, 160);
