Java MouseListener - Events

Question

Does any know if the following is the expected behaviors in terms of what MouseEvents are fired? One seems to be missing or consumed elsewhere.

1. Right-click on JPanel and display JPopupMenu:

   MousePressed java.awt.event.MouseEvent[MOUSE_PRESSED,
     (469,347),absolute(2214,490),button=3,modifiers=Meta+Button3,
     extModifiers=Button3,clickCount=1]
   
   MouseReleased java.awt.event.MouseEvent[MOUSE_RELEASED,
     (469,347),absolute(2214,490),button=3,modifiers=Meta+Button3,
     extModifiers=Meta,clickCount=1]
   
   MouseClicked java.awt.event.MouseEvent[MOUSE_CLICKED,
     (469,347),absolute(2214,490),button=3,modifiers=Meta+Button3,
     extModifiers=Meta,clickCount=1]
   

   So far so good all 3 from button 3 and in correct order

2. With JPopupMenu still showing left-click somewhere in the JPanel not in the JPopupMenu:

   What happened to the MousePressed event?

   MouseReleased java.awt.event.MouseEvent[MOUSE_RELEASED,
     (452,339),absolute(2197,482),button=1,modifiers=Button1,clickCount=1]
   
   MouseClicked java.awt.event.MouseEvent[MOUSE_CLICKED,
     (452,339),absolute(2197,482),button=1,modifiers=Button1,clickCount=1]
   

Thanks in Advance.

Answer 1

So the event that causes the popup menu to close has disappeared.

IIRC, exactly how this is implemented changed from 1.5 to 1.6. In 1.5 there is a glasspane, in 1.6 AWTEventListeners are used. See BasicPopupMenuUI sources for details. It looks as if you can (globally) stop the event being consumed with:

UIManager.put("PopupMenu.consumeEventOnClose", false);
