How to put a component on top of all other components?

[Mickey Segal]

For adding components on top of other components, all code that I've seen
uses the method "add(Component, 0)" to add a component such as a ToolTip on
top of other components. Such "add(Component, 0)" code works everywhere
that I've tried except for the Macintosh implementation of Java 1.4
(demonstrated with a working applet and full source code at
http://Segal.org/java/AddOrder2/).

I can't find anything in the Java documentation to argue that the Macintosh
Java 1.4 behavior must be considered a bug, so I am not holding my breath
for Apple to change their implementation. Numerous GUI bugs that were known
since Apple Java 1.4 was released have not been fixed (details at
http://segal.org/macjavabugs) so arguable errors are likely to get even less
attention.

Is there some other way to place a component on top of others? I can't just
use Java 2 ToolTips; the goal is to create a Choice-like component that has
more functionality than the standard Choice, using a pull-down section that
will overlap other components while it is pulled down.

For adding components on top .. Macintosh implementation of Java 1.4

Are you _sure_ the Mac is using 1.4?

AFAIU, in some Mac implementations you have
to configure Java jars to use 1.4 specifically,
otherwise they default to 1.3 (shrugs - go figure)

It would be interesing to see what
'wassup' reported for the Mac in qn.

BTW - why the 3 x X-posting?

I think this might be best suited to
c.l.j.programmer for the moment,
so I'll direct f'ups there.

Yes, Macintosh Java 1.4 can be recognized with confidence by those familiar
with its many known bugs (e.g. http://segal.org/macjavabugs/) and by its
self-reporting of MRJ version as tested with
http://segal.org/java/configuration/ (non-Safari browsers use the older
3.3.3; i.e. Java 1.3).

BTW - why the 3 x X-posting?

Sorry. I almost always post just to c.l.j.programmer but this is a very
GUI-specific issue so it was unclear what the best choice should be.

OK well, if I'm wrong about the version,
it might pay to reinclude c.l.j.gui,
cannot see a reason for c.l.j.help though,
we would just confuse the posters there!

Using Java 2 would cut out a majority of our users in order to satisfy the
small number who use Java 1.4 on the Macintosh. Is there any Java 1.1 way
of doing this?
