title: Disabling all Keys and Key-Combinations in JAVA
body: <p>I want to disable the Windows-Key and all Windows-Key + X Combination while my Dialog is Visible. 
  CTRL + SHIFT + ESC and ALT + TAB should be disabled too. 
  Is this possible?
  I Just want that my JDialog is always on Top, so not even the StartBar should be Visible.
  Can someone help me with that out?</p>
  
  <p>EDIT: Or a way to disable the keyboard.</p>
