title: Panel for drag and drop image file, with java swing
body: <p>I'm trying to make a java swing panel, where you can drag and drop images. And save the images displayed on the panel.
  I found <a href="http://www.java2s.com/Code/Java/Swing-Components/GlassPaneDragDrop.htm" rel="nofollow">this</a> which I think would help me a lot.
  But on my computer with windows 7 does not work. I can not drag images to the application. I would appreciate any advice. thanks</p>
