Programmatically clicking a GUI button in Java Swing

Question

How would I programmatically click a Swing JButton in a way that would register all the relevant action/mouse events and be visible to the user (i.e. they\'d see the button

Answer 1

If doClick() is not what you want, you can move the mouse really to the button and press it:

public void click(AbstractButton button, int millis) throws AWTException
{
    Point p = button.getLocationOnScreen();
    Robot r = new Robot();
    r.mouseMove(p.x + button.getWidth() / 2, p.y + button.getHeight() / 2);
    r.mousePress(InputEvent.BUTTON1_MASK);
    try { Thread.sleep(millis); } catch (Exception e) {}
    r.mouseRelease(InputEvent.BUTTON1_MASK);
}
