This is caused by not having the gnome jar in your classpath. You need both the
classpath set correctly so java finds the java libraries and the LD_LIBRARY_PATH
(-D) setting so that they can find the native part of the libraries.

Re: [Java-gnome-developer] Re: About window

[Rishabh M. <rma...@gm...>]

Hi,
Thanks for writing back. 
I tried using Program.initGnomeUI(I think thats wat u meant) and used
showAll on every widget. Yet I get the same error.
What I mean by nothing happens is that Once I have opened the
Help->About window(all the click events on the menubar are working
just fine), No click events are registered on the About window which
has just been opened. For example when I click on Close, the window
doesnt close, if I click on credits, the new window showing all the
credits doesnt open up either. Basically No click events work on the
newly opened About window. However, the main window still works just
fine.
I hope this clears up what I meant by nothing happens. 
I am attaching my .java file incase you/someone has time to go over it
and suggest a solution/workaround.
Thanks

[Java-gnome-developer] Java-Gnome Changes

[Mark H. <mh...@ti...>]

Hello,

A lot has been happening in the java-gnome world over the past week, this email
will hopefully let you all know about it.

Java-Gnome developers have unfortunately been too busy in real life lately. New
developers wanting to help out have had their questions left unanswered and 
some confused java-gnome users have been getting even more confused due to our
lack of good up to date documentation and replies to their questions.

We want to change all that. And we are doing. We're making a number of changes
to make life easier. So, the changes so far:

Bug tracking moved to bugzilla.gnome.org. 
This gives us a far superior tool for tracking and dealing with bugs in
java-gnome. It also makes it easier for gnome developers to get involved. We're
going to move all existing reports from the sourceforge system to bugzilla over
the next few days. If you have an open bug report, please move it over yourself
so we might have more time to answer the report.

New website: http://java-gnome.sf.net/cgi-bin/bin/view/
This is still very much under development, but we really would love to hear your
views on it - if you think something is missing, or could be said better, please
let us know, or just fix it yourself. The website is a wiki, so we would really
like everyone to contribute -- please consider giving something back in return
for the java-gnome bindings.

Binary Packages
They're coming. The website will now keep up to date info about them too

Release status
2.8.0 has been released, but we didn't make an announcement. We have some big
fixes to the build system in cvs and they will be in 2.8.1 release, which will
have a release announcement.

HintsAndTips
A new section to the website. This is where we really want your help. We want
any hints and tips for java-gnome newbies and also experienced developers.
Absolutely any topic you think is useful. Please give us your tips. If you need
advice on how to do something, add it to the hintsandtips section so that
someone will tell you how.

JavaGnomePrimer
Our tutorial at the moment tells you how to write java-gnome apps using our api
alone. With tools like glade and eclipse, there are far better ways of
developing applications with java-gnome. This primer will perhaps replace the
tutorial, telling new users how to do these things. The primer is still very
much in need of work -- please consider sparing a few moments to write a section
of it, or just review what's already there. Add your comments to the primer
itself. That's why we made it into a wiki after all

I look forward to seeing lots of changes in the website RecentChanges page and
hope that in the future java-gnome can be even more useful for you.

Re: [Java-gnome-developer] Re: About window

[Mark H. <mh...@ti...>]

You definitely need to use Program.UnitGnomeUI -- this will load the static
gnome libraries (so it can find gnome_about_new). What exactly happens when you
say the window opens but nothing can be done with it?

BTW: you should use showAll() in preference to show() -- in fact, that might
hopefully solve your problem :)

Re: [Java-gnome-developer] properties patch?

[Mark H. <mh...@ti...>]

Hi, 

Sorry for taking so long to reply. We (java-gnome developers) have been far too
busy in real life recently. We're starting to get on top of java-gnome bugs.
Hopefully we should look at this in the next couple of weeks. It'll probably be
moved to our new bug tracking system (bugzilla.gnome.org) first though.

This is a bug. We're obviously using prefix/lib/jni rather than libdir in the
gnome makefiles. Please report this to bugzilla.gnome.org

Did you manage to get the rest of the library compiled in the end?

Hi,

Sorry for taking so long to reply.
The following page should help answer your question:
http://java-gnome.sourceforge.net/cgi-bin/bin/view/Main/WhyJavaGnome

That page says why to choose java-gnome rather than alternatives. There is a lot
more that could be said on that page -- if anyone is reading this who knows what
those things are (comparing java-gnoe to alternatives), please add them to the
above page.

Re: [Java-gnome-developer] bonobo and eclipse

[Mark H. <mh...@ti...>]

Hi,

Sorry for the late reply.

Java-Gnome provides an API for writing java applications with gtk or gnome
interfaces. Eclipse uses an alternative, SWT, for its interface. If you want to
get eclipse to use a bonobo editor, you probably have to use a swt bonobo
component. 
I could be wrong though, so if you'd like to loko at eclipse source more, please
feel free to do so. AFAIK, the only eclipse plugin related to java-gnome did not
do anything with a java-gnome ui, it just had helper scripts for creating
java-gnome projects. Again, I could be completely wrong about this --
unfortunately this eclipse java-gnome plugin is no longer maintained and the
developer cannot be found.

Are you maintaining gstreamer bindings with the gstreamer project, or just as

Sounds like a good idea. I think the function we're using now was written when
we only had gtk bindings and so it was perfectly sufficient. Please file a bug
in bugzilla.gnome.org (java-gnome module) and we'll take a look at it
(with a patch, if at all possible)

That's one of the actions arising from the email thread on that list. Jeff's in
charge of the mailing lists and sourceforge project, so he'll have to sort out
the lists themselves, but I've certainly added the mailing list to the wiki

Bloody good question. I've suggested that java-gnome...

a) move its mailing lists to gnome.org

b) make both lists available (if -hackers is moderated to join, so be
it, but at least publicize it).

and

c) clearly differentiate what audiences the lists are for.

... but I'm not sure what is involved technically, or who has to be
nudged at GNOME for this to happen.

There also seems to be an undercurrent that sourceforge isn't the
greatest place to host bug tracking, so perhaps that should move to
bugzilla.gnome.org as well.

No reason not to leave the masthead banner home page at sourceforge, of
course.

If you don't know what Mark and Jerry are talking about, there's a

It started out wondering where j-g was going, and resulted in
expressions of support and quite a bit of activity.=20

This is nearly exactly what I'm talking about... in fact my approach
uses libffi also. Right now I'm working on it for GObject specifically,
not a general purpose JNI replacement.

Right now my approach is using Java 1.5 metadata and annotations to
decorate Java classes about how they link up to their GObject
equivilent. For instance, the bindings to GtkObject might look like
this:


@GBindClass(Library="gtk-2.0", Name="GObject",
TypeSymbol="gtk_object_get_type")
public class GtkObject extends GObject
{

	@GBindMethod(Name="do_something")
	public abstract void doSomething();

}


At runtime, the metadata for this class would be detected, the specified
library would be loaded with dlopen(), the TypeSymbol would be called in
order to return the GType, and all the method's marked @GBindMethod
would be replaced with proxy's to the underlying method calls.

Since there is no method introspection: at compile time, the .h files
would be scanned, and the .class file would be "enhanced" with
additional metadata that defines what byte offsets the function pointers
for the methods are at.

Creating a new GObject would be as simple as overriding an existing
wrapper.

public class MyNewGObject extends GObject
{

	public void doSomething()
	{
		// do stuff
	}

}

This would create a new GObject in the GObject system with a name like
"__java__package_name_Foo", set up that it inherits from GObject, and
override GObject's methods with libffi generated stubs.

I'm working on some prototype code for this now, to generate GObjects
from thin air at runtime, and to hook up method/signal calls. I don't
have many outstanding issues to figure out before I actually get coding.

Anyways, please comment.

Re: [Java-gnome-developer] RE: Mark Howard's Blog

[Mark H. <mh...@ti...>]

Hi Jerry,

I've decided to put a little more effort into java-gnome. After writing the blog
entry, I sent a message to java-gnome hackers mailing list. There is a
tremendous amount of support for java-gnome, it seems that we've just been
failing to channel that into productive work recently. We all have ideas about
where improvements can be made and things are looking very positive in this
respect -- we are already starting to make them.
If you're interested, please go to our temporary developmental website (I only

That's a really good point. 
Also for companies working with java-gnome, that really is something we should
think about more. AFAIK, lots of people really want gnome to be adopted more in
business. If java-gnome can help with that, then we might be able to help a lot
by modifying our website a little.
One thing I really would be interested in is extending the applications page of
the website -- having some user (developer really) comments would be really
helpful, even if it's just a couple of lines saying "I work for a company that
does foo; we use java-gnome internally for x, y, z; we chose to develop with
java-gnome because..." -- Do you think you might be able to start us off with
that?

It is a pain, but I feel we are really close now. The cvs modules reorganisation
have made a huge impact. New developers getting involved will also be easier in
the next 6 months since we will be developing against a stable gtk+ release.

I've heard other comments about people working on TreeModels, but don't know any
details.

Wow. That would be really amazing.

Any tips on how to do this?

Sure, sounds very interesting, especially if it might make it easier to develop
the bindings -- so that we can concentrate on designing a really good API.
Please add them as a new page on http://java-gnome.sf.net/cgi-bin/bin/view/ ,
linked to the development page. That way your ideas won't get lost in email
archives.

Talking about JNI, you might be interested in GDirect:

Seems like your idea, if what you want is to get rid of it.
