I am a bit confused regarding KeyEvents. I need to listen for the user 
pressing a specific F-key. Is it not possible to set a key-listener for an 
entire frame? It seems like the event is not comming through to the frame, 
if the active control has any kind of key-listener (like a TableFrame).

I am used to the events bubbeling up from a compunent to its parent until it 
hits the container in Delphi. Is this different in Java?

In this project I am compiling to a Java application (JAR executable).

I am using JBuilder2005, but I suppose that does not make any difference.

I had this kind of considerations before. As a general rule (which may 
have exemptions), nothing in Java Swing happens in a systematic way and 
all seems to depend on arcane handling knowledge. Unfortunately! - We 
may guess that time restraints have played a roll in design here.
