title: How to open a new jFrame with denied access to the previous jFrame
body: <p>I want to open a new jFrame by clicking a button in another, while blocking the access to that jFrame. That means....like in message boxes.when a message box opened by clicking a button in a jFrame, we cant access the jframe anymore until we close the message box.if we try to click on the jframe there it makes a beep noise that reminds us there is a message box opened.
  Likewise I need to do this to a new jFrame.when a new jFrame opens by clicking a button on the previous jFrame,the previous frame should not be accessed anymore(should not be closed) until I close the newly opened frame. How can I do this.Is there any simple change in the property of the jframe in Netbeans(without writing codes).</p>
