[cp-patches] Fix for Component.postEvent for top-level components

[Dalibor Topic]

Hi all,

the attched patch fixes postEvent for top-level components, by only 
delegating unhandled events to the parent component in case that a 
parent component exist. It's been reported after Stephane tried out 
Odonata on Kaffe [1].

Also attached is a small test case. And the obligatory ChangeLog entry is

2004-09-16  Dalibor Topic  <address@hidden>

        * java/awt/Component.java (postEvent):
        Only delegate to parent if a parent exists.

        Reported by: Stephane Meslin-Weber <address@hidden>


cheers,
