  • glasspane doesn't consume keyevents
  • have add keylistener jcomponent added glasspane, , override consume()
  • mouseevents consumed in area covering jpanel or jcomponent, top component on hierarchy
  • add jlabel (transparent default) covering whore rootpane area, add proper layoutmanager jlabel, there put jpanel or ....
  • invoke glasspane jframe.getrootpane
