Overlapping listeners in layers, help

Question

Hi,
I have one more question.
I am using a JLayeredPane, and in there i have multiple panels in different layers.
Each panel has it's own mouse motion listener, and the parent panel containing layered pane also has mouse listeners.
depending on which panel is on top, i want different things to happen.
I noticed that when the parent panel has its mouse motion listener working, the listeners of the panel who is at the topmost layer don't work.
how do you control multiple listeners of overlapping layers?

Answer 1

The top layer (parent's glass pane?) will always grab the click. Java makes a good guess, like using a Button if it's added to a Panel but if your needs are more complex, you should take over and not depend on a layering scheme.
Set some sort of flag when you change panels. Then have your code call an appropriate listener based on the flag:
final static int
    THIS_PANEL = 1,
    THAT_PANEL = 2,
int activePanel = 0;
// after setting thisPanel
activePanel = THIS_PANEL;
// in main mouse listener
// MouseEvent is "me"
switch activePanel {
  case THIS_PANEL:
    thisListener( me );
    break;
  case THAT_PANEL:
    thatListener( me );
    break;
  default: // whatever
} // end switch
