Re: Detect when menu is c

> Reading it up once again I see I've got it wrong.  Now I see you
want a single action listener for all menu items and you want it
called back for any new items there may be added to the container,
right?  I'm sorry to say I haven't thought about that.

I don't know whether I understand this, but let me try to rephrase my
question. Assume you have the menu:
A
+- B
|  +- C
|  +- D
|
+- E
   +- F
   +- G

Now, assume you click on A. It would open this:
A
+- B >
+- E >

This is because A is e.g. JMenuBar that is activated by a click, not
by mouse roll over. Now, if you only roll over B and wait, but not
click, you will get the following:

A
+- B
|  +- C
|  +- D
|
+- E >

This is what is called selection. I can get notifications about this
by adding the following:

		menu2.addItemListener(new ItemListener() {
			public void itemStateChanged(ItemEvent e) {
				System.out.println("menu2: itemStateChanged: " +
e.getStateChange());
			}
		});

before the for loop in my code sample. This is not what I want.

Assume now, in this state, you actually move your mouse over C and
actually click on C (which is a JMenuItem). It will raise an action
event on the respective MenuItem instance. You also get this if you
type Enter while item C is selected. That is a normal behavior. What
is important is that method is not relevant - whether I click with the
mouse or press Enter key on my keyboard or I have an application
programmatically generate this event - is irrelevant and that is a
good abstraction. I get actionPerformed, which means the item has been
chosen.

Now, assume you move your mouse over B and actually click on B (which
is a JMenu). What I would like is that the action listener I
registered this receives this. The only thing I get is mouse clicked
event, as demonstrated by the example. I cannot get keyboard events,
nor can I get action events. This is logically incorrect from my
perspective:
- JMenu is a descendant of AbstractButton - you, by every logic,
should be able to click on buttons and react, shouldn't you?
- You can receive mouse, but not keyboard events
- You cannot determine that JMenu has been chosen, you can only
determine whether it was (de)selected

Hope this explains the problem and the solution I am searching for in
a better way.
