This week's giveaway is in the EJB and other Java EE Technologies forum. We're giving away four copies of EJB 3 in Action and have Debu Panda, Reza Rahman, Ryan Cuprak, and Michael Remijan on-line! See this thread for details.
In the javadoc for java.awt.Component.getLocation(), there is such a description:
Due to the asynchronous nature of native event handling, this method can return outdated values (for instance, after several calls of setLocation() in rapid succession). For this reason, the recommended method of obtaining a component's position is within java.awt.event.ComponentListener.componentMoved(), which is called after the operating system has finished moving the component.
But I don't understand what this statement means and if the call isn't reliable at all why it is there? If I dont want the trouble of using a listener, how should we use getLocation() to retreive the component's location?
