#1482 — javax.swing.JPopupMenu ca

  To: comp.lang.java.gui
Hello All,

 To get the text of runtime built menu items, I used the following
code:
-------------------------------------------------------------------------------------------------------

	//Create a change listener and register with the menu selection
manager
	    MenuSelectionManager.defaultManager().addChangeListener(
	        new ChangeListener() {
	            public void stateChanged(ChangeEvent evt) {
	                // Get the selected menu or menu item
	                MenuSelectionManager msm =
(MenuSelectionManager)evt.getSource();
	                MenuElement[] path = msm.getSelectedPath();
	                if (path != null && path.length > 0){
               ------------>      String m_sSelectedMenuItem =
((JMenuItem)(path[path.length - 1])).getText();
	                }
	            }
	        }
	    );
-------------------------------------------------------------------------------------------------------
However, I recieve the following exception
     java.lang.ClassCastException: javax.swing.JPopupMenu cannot be
cast to javax.swing.JMenuItem
on the stared pointed line above.
This is obviously also hardens my debugging work as the exception
always being thrown when I select the menu item...

Any ideas?
Many thanks!

1) instanceof
2) 
try {
  ..one
catch(CCE) {
  try {
   ..the other
  catch(CCE) {
   ..debug the code
  }
}
3) redesign it

First andrew thanks for the reply.
Second, It may be the late afternoon which causes me a little to
misunderstand your suggestions... I'll be glad to get more detailed
help. I really didn't understand the solution...
