Hi,

I'm searching a way to make a Applet running in full fullscreen on
MacosX. Including no menubar in top.

any idea ?

That would depend on the browser.

Why an applet? What does the applet do?

The applet is based on the PApplet of processing.org . It allows
animations and stuff like that ...
I once heard about making an application fullscreen and then incorporate
the applet in it . Would that be possible ?

So, you control the code? [1]

There are some nice applets there, well suited
to Java based screensavers.

[1] Sure, but if you have the code, it is a lot easier
to add a main() to the applet so it can run as an
application as well. Then you can have the best of
all worlds.

The code of processing.org is opensource and freely downloadable. It
produces an applet and I would not like to modify the processing.org
code .
That's why I produce an Applet too ...

I've checked , but the framewwork is not supported on Macosx ...

Adding a 'main' to the applet is OK, but what should I put in it to
produce fullscreen output ?

Convert an applet to an application:

http://www.rgagnon.com/javadetails/java-0305.html

Use JNI to bridge Java to Cocoa:

http://java.sun.com/docs/books/tutorial/native1.1/

Use Cocoa to set up a full screen:

http://developer.apple.com/technotes/tn2002/tn2062.html

PS. I can't promsise this all works...and it sounds pretty complicated
to me. I'm just suggesting this as one avenue to investigate.

When you're done, you'll have a Java app that only runs on OS X,
however, unless you write full-screen windowing libraries for each other
system you want to run it on.

Why not just use Cocoa to begin with? The entire Cocoa API is exposed in
Java anyway, you would just have to use Cocoa drawing commands instead
of AWT/Swing. It would be pretty simple with Xcode 2: you can link
straight to the OS X screen saver framework.

Did you find a mac-specific solution or something cross-platform?

I did not try it, but it should work cross-platform ... However other
platforms don't have the menubar on top of screen, so that should not be
a problem at all

Probably no way. An application could do it, maybe, with JNI calls to a
cocoa library that you write to set up the full screen window.

Caveat: I haven't done applets in a long while.

In theory, it might be possible for your applet (in Java 1.4) to:
a) get the local java.awt.GraphicsEnvironment
b) from that, get the java.awt.GraphicsDevice[]
c) find the appropriate one (should be a TYPE_RASTER_SCREEN)
d) check that it supports full screen (call isFullScreenSupported() )
e) create a Window to draw on
f) pass that to setFullScreenWindow()
g) do your layout on the Window

(Substitute Window subclass as appropriate for your purposes.)

I rather suspect that your greatest difficulty will be getting all that
past the security manager. (Are Applets even allowed to spawn new windows
or frames? I told you it's been a long while since I touched applets.)

Anyhow, the code to get a Java _application_ to go fullscreen on my iBook
is only about seven lines of Q&D code. Doing it right shouldn't take more
than 10 to 15 lines.
