  • Show the entire class code. From the code shown, we can't determine what "this" refers to. What Component are you trying to set invisible? – FredK Mar 31 '18 at 18:48
  • Use `DrawMap.this.setVisible(false);` or more simply `setVisible(false);` Otherwise `this` refers to the anonymous inner class. – Hovercraft Full Of Eels Mar 31 '18 at 19:27
  • I try DrawMap.this.setVisible(false); but still Frame is not hide –  Apr 01 '18 at 14:00
