I know  thet the actual java event model is the delegation model (that
substituted the containment model) , based on a source target interaction.
Here are the questions:

1. I read on a jguru course that AWT events are not garanteed to be
dispatched in a definite order: is this true even in the jdk1.2 , so that if
you register two listeners with the same source and the second need the
result of the response of the first, this is not a good idea, because it is
not guaranteed that the second listener will receive the event after the
first one?
2. Is this true even for swing classes ? I was conviced that events are
processed synchronously and that they are dispatched in the order listeners
are registered, because the source take them out in order from the list (a
Vector I think) and call the adhoc method of the listener (say
actionPerformed, for example).
3. Why is there this difference (if there is any) between AWT and swing?


Thanks in advance
