Question

I am using Java to generate a mouse press using the Robot class:

robot.mousePress(InputEvent.BUTTON1_MASK);
robot.mouseRelease(InputEvent.BUTTON1_MASK);

However, I want the Robot to press the button for a certain period of time. How can I achieve this?

Answer 1

Just sleep a bit between the two actions (specified in milliseconds):

1. Thread.sleep(long millis);

   robot.mousePress(InputEvent.BUTTON1_MASK);
   try { Thread.sleep(1000); } catch(Exception e) {} // Click one second
   robot.mouseRelease(InputEvent.BUTTON1_MASK);
   

2. Robot.delay(long millis);

   robot.mousePress(InputEvent.BUTTON1_MASK);
   robot.delay(1000); // Click one second
   robot.mouseRelease(InputEvent.BUTTON1_MASK);
