Not at the moment.

Your interest seems to break down into two tasks:

1. Write an applet
2. Access all open windows and command them to minimize.

(I'm actually wondering if you're mis-using the term "minimize" here;
the opposite of Window.maximize() is Window.unmaximize(), aka restore.
To minimize is to iconify out of view)

The second part is tricky because it implies talking to the window
manager and using it to command all open windows (not just the ones in
your program) to minimize.

As for the first part, I spent quite a bit of time at linux.conf.au last
week talking to Davyd Madeley (gnome-applet maintainer) about applets
and it turns out a) they are really rather complex due to the fact that
the panel has bonobo get a factory which then creates instances, and b)
the applet library & API really needs a rewrite, as they know language
bindings around it has been really tough.

I have some thoughts on the topic (look for a blog posting from me
sometime this week on the subject) but the immediate answer is that we
don't have a language binding around "lib panel applet" at this time.

However if you want an applet to minimize all windows, there already is
one - the "Show Desktop" applet. If you know about that and it doesn't
quite do what you want, you may find a few lines of C code may get you
your heart's desire... or you could join java-gnome-hackers and help us
write a libpanelapplet-java binding :)

As ever with Open Source software, the directions and priorities are set
by those who make the contribution. I too would love to see a language
binding around evolution-data-server, but I myself don't have the
technical competence to understand their APIs (sic). 

That's actually a fairly major theme for us - we're all attracted to
java-gnome because we want to do GNOME programming from Java. Go figure.

But that also indicates the background of most of us. I started with C
in the 80s and have a reasonable facility with it but want absolutely
nothing to do with writing application code in Glib/GTK C today. On the
other hand, all the guys who understand how to code GTK in the original
C layer have already mounted that learning curve and have no reason to
use (and thus help us fix) Java bindings.

So whenever you see an long time GNOME person in #java-gnome, give them
a hug. :)

As for eds, I'd love to see a binding but it have to wait until someone
can invest the time in learning their API and then wrapping it. Given
that Novell paid a bunch of guys to do that for the C# binding is indeed
worth leveraging when the time comes.

[Java-gnome-developer] Evolution Data Server

[Trond A. <tro...@gm...>]

I saw a few posts regarding Evolution Data Server (eds), but could not
find any major posts on the mailing list regarding this subject.

Are there any plan to add support for eds, or is this down prioritized
compared to other APIs which have been under Gnome umbrella for a
longer time?

The reason I'm asking is that I'm considering adding a feature to
Freemind (http://freemin.sf.net) that would require eds APIs available
from Java.

I also browsed the source code from eds and found the "glue" code used
by the C# API. Does anyone know if this glue code actually would give
any value seen from a Java-Gnome perspective?

[Java-gnome-developer] Preventing minimize

[Andrew C. <an...@op...>]

I've written a small applet like program (which I intend to *make* an
applet, but that'll come later) which tells you whether or not the drive
is spinning. It just displays a little indicator icon in a tiny
undecorated, skip taskbar, skip pager, keep on top window.

Since it's undecorated, there is no minimize button, but I just hit (by
accident) Alt-F9 on it when it was focused and poof it disappeared...
then I realized that I had minimized it and since its not in the taskbar
or pager it can't be Alt-TAB 'ed to get back on screen. So. Kill
program, restart. Oops.

What I need to do is trap the minimize (iconify?) event and then ignore
it.

I'm sure there must be a GTK signal for this, but I couldn't find it
anywhere in our bindings. I would have though that this would have been
in LifeCycleListener's LifeCycleEvent.TYPE, but apparently not. Maybe
one of the things there *is* what I'm looking for, but the javadoc there
is rather sparse.

Any suggestions?

[Java-gnome-developer] It's java-gnome week!

[Andrew C. <an...@op...>]

Hey,

The next 7 days will be java-gnome week!

{Mumbles in the background . What's he smoking?}

There are lots and lots of people who lurk in the java-gnome community.
There are hackers old and new who have made contributions through the
years, and many more who have watched our progress with enthusiasm and
support. But we don't have any full time hackers devoted to the bindings
nor do we have a compelling set of projects which drive us to meat
release deadlines. It's easy to forget the thing we have in common and
certainly there are always other calls on our time.

But not next week!

Starting tomorrow we're going to shake the tree and beat the bushes and
see what we can scare up! That's right. Anything you've been thinking of
working on, NEXT WEEK IS YOUR WEEK. Patches, feature requests, helping
out new developers. Come one, come all, now's the time to get it in! For
the next 7 days we're all going to be rabidly enthusiastic and see what
we can achieve.

And at the end of the week we will release libgtk-java 2.8.3 (and any
other of our libraries that get some love)!

So drop by #java-gnome and say hello. Ask questions. Discuss on our
mailing lists. Update the wiki! Fix bugs. Clean up the example code.
Better yet, fire up your box, update your sources, and fix that little
thing that you've been meaning to do. Or if you're working on an
application that uses java-gnome, why don't you push out a release next
week and tell the world!

Me? I'm going to see if I can get a binding around gnome-applets going.
Anyone want to help?

...I'll see you 'round the net! And anyone who's going to be at
linux.conf.au in Dunedin, NZ next week, be sure to say hi...

Hi Stefan,

I believe the problem is that your libgtk-java and glib-java versions
are not in sync. If you plan to use libgtk-java-2.8.1, please use
glib-java-0.2.1, and if you're going to use glib-java-0.2.2, please use
libgtk-java-2.8.2.

See how it goes and get back to us all. :) You are also welcome to

[Java-gnome-developer] TreeView Focus OUT Problem

[Damian M. <da...@sp...>]

I have a problem with loosing focus of Renderers in a TreeView.

Whe you edit a cell in the treeview and after stopping edit you click a 
button or other
component - then you don't lose the focus of the treeview and don't lose 
focus on the Editor component so
the event cellRendererTextEvent is not triggered so the changes you have 
just made doesn't go to the model
of the treeview.

This can be avoided by after editing the cell you must click somewhere 
else in the trieview
so the cell loses focus and then everything works, the event is trigered.

Anybody faced this problem ? Any solution for this ?

I've tried grabing focus of other componets and focus listeners and so 
on but nothing
solved the problem.

this makes the combo with scrolls and is searchable

I've tried setting the property from the java-gnome API on the combobox 
or on the combobox style with no effect.

[Java-gnome-developer] LinuxTag 2006 - Call for Papers

[Robert S. <the...@gm...>]

Hi all,
this years LinuxTag takes place in Wiesbaden/Germany on May 3-6 . Like last year
the organizers plan to have a Java track. As a free software event there is lots
of interest to have presentations about GNU Classpath and all its related F/OSS
projects.

Please take this as an opportunity to tell something about the project you are
involved!

The call for papers is already open and ends at January 15th. You do not have to
submit complete documents for this date. All details about the requirements for
speakers can be found here: http://www.linuxtag.org/2006/en/home/cfp.html

I hope to see some of you in Wiesbaden. :)

cya
Robert

You'd think so.

Huh. The only time I tried to do something like this I was overriding
abstract methods anyway so they were implemented in the Bar class
anyway.

Suggestions:

1) put
	doFoo() {
		super.doFoo();
	}
into Bar.java

2) look at the code for LibGlade(). It's pretty hairy but it could well
be doing something un-java-ish that it needs to be doing. It sounds like
it's looking for a method doFoo in Bar only, not in Bar and its
supertypes. I've not done much with reflection but I suspect that
whatever LibGlade (and it's C JNI counterpart) are doing it's not doing
it quite right.

3) Be smart about it and don't use signal auto-connection. Use
addListener() instead.

Re: [Java-gnome-developer] using inherited methods in glade signal handlers

[Lars W. <la...@di...>]

Hello again,

since nobody answered to my previous question, let me try to ask it
again a little bit different and perhaps more clearly.

Let's say I have a class Foo:

        public class Foo {
                public void doFoo() {
                        System.out.println("Foo!");
                }
        }

Then I have another class called Bar extending Foo:

        public class Bar extends Foo {
                public Bar() {
                        try {
                                ui = new LibGlade("UI.glade", this);
                        }
                        catch(Exception e) {
                                e.printStackTrace();
                        }
                }
        }
        
Shouldn't it now be possible for me to specify the method doFoo() as a
signal handler in UI.glade (e.g. for a button click)?  Currently, when I
try to do something like this (or at least something similar), I get an
IllegalAccessException.

Regards,
Lars
