title: jframe actionperformed jframe
body: <p>I currently have a button that, when clicked, performs a method that creates a jframe with a panel that loads multiple images. If this button is clicked multiple times, the images keep adding onto the prexisting images loaded onto the jframe. What code should I use so that if the button is clicked after the jframe and elements have been loaded, after clicking once, nothing else will be added.</p>
  
  <p>Many thanks</p>
