[Java-gnome-developer] I'm Compiling Java-Gnome For Windows

[Jerry H. <jh...@fe...>]

Yes, you heard it. I'm giving it a shot. I don't think it should be too
hard, all of Gtk at least is available. The build system does suck. I
have a few ideas for that now after having looked at it.

Has anybody given this a shot yet? It doesn't seem that hard to me. The
JNI files will be compiled against the GTK distribution that Gimp gives
out, should work fine. Obvious pieces like Gconf aren't going to work.

I'm looking for advice. :0

Re: [Java-gnome-developer] java gnome app...

[Sean C. <exc...@gm...>]

Thanks for your response Mark,

I appreciate your renewed effort with regards to correspondance on the
java-gnome mailing list, i'm working a on and off on a few other
java-gnome projects right now... most concentrating on time saving
frameworks around java-gnome.

I work in an XP team, and we unit test and acceptance test all our
apps, i've being working on an acceptance test framework for
java-gnome and look forward to telling ye guys about it when its
ready. i believe it'd be the first acceptance test framework for
gnome?

I've also been working on an xmlGuiBuilder which ties into my HMVC
framework for java-gnome for event firing and event listening, and it
will allow for quite a nice seperation of domain and gui in my humble
opinion.

Again thanks for all your hard work, and i will add jbalor to the list
of apps on the website.

[Java-gnome-developer] Busy loops

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

I'm writing something that is mostly doing a lot of hard work in the
background; the GUI is just there to report status.

Obviously I'm going to be updating a Gtk.ProgressBar as I go.

The question I have is how best to structure such a program? Event
driven programs, of course, get kicked off when

	Gtk.main()

gets called, at which point you "loose" the conventional thread of
execution.

Should I be starting a new thread, just before the call to start the
main loop, to do all the work, and then just update the ProgressBar and
Labels as necessary from there?

In fact, other than someone hitting "Cancel" there are no [user] events
that I'm expecting.

For some reason Gtk.mainIteration() comes to mind, but I'm not sure how
that fits in with main()'s loop.

Any pointers? [Either java-gnome or GTK best-practice or...]

Re: [Java-gnome-developer] debbuggtk

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

A bugzilla backend to debbuggtk would be excellent. Bugzilla has quite a nice
xml interface, so it should be really easy to access that. The problem is that
debbuggtk is very much debbugs specific at the moment and is also not writen
particularly well. Adding bugzilla support would give me a chance to make a few
important design changes which debbuggtk desperately needs and as you say it
would be extremely useful (I only know of one other bugzilla viewer - that was
written in xul and when I tried it, it wasn't very impressive)

I guess the short answer is that I'd love to add bugzilla support to debbuggtk
and make it into a flgship application for java-gnome. Unfortunately at the
moment I really don't have time to do that, especially not on my own. I might
start drafting some designs for it though. I'm interested again.

[Java-gnome-developer] debbuggtk

[Luca De R. <pie...@fa...>]

Mark, I've always had in mind that an official j-g application would be
great to demonstrate concretely what j-g can do.
AFAICT the most maintained and active j-g app is debuggtk.
I've always thought if it's designed in a way that it's easy to add new
backends, namely I've always thought about a bugzilla backend.
Now that we use bugzilla, would be great if sometime in the future we'll
have a team developed app that we find useful too.
I've read that bugzilla makes extensive use of perl. Do you think there
will be a way to use it from java?
What do you think about this long-time proposal?

> WHY I SHOULD USE JAVA-GNOME TO DEVELOP MY APPLICATION?

Don't shout.

It basically boils down to this:

There is a group of people who want to write GNOME/GTK apps using Java
in order that they can create applications that work well on Linux,
specifically on a Gnome desktop. And we are all doing so quite happily.

java-gnome a Gnome language binding. That's it. That's the job spec.=20

Many Java developers, seeing the possibility of writing cross platform
applications, become obsessed with writing cross-platform applications.
It tends to mean they have trouble seeing past Swing.

There are, however, many reasons why someone might want to choose NOT to
write a cross platform application. One I can think of off the top of my
head is "I'm an open source software developer, and could give a *beep*
about Windows". More precisely, I am working on Gnome applications for
Linux, and so am pleased to have a framework that allows rapid
application development (Eclipse + Glade + Java-gnome + GCJ) of Linux
native binaries from my preferred language, Java.

As for "reasons", well, I've observed the performance of the java-gnome
language bindings to be fine, and am certain that it will but improve
over time. Certainly operating directly with native widgets means there
is none of the widget emulation that Swing and SWT are forced to use.

Here
http://java-gnome.sourceforge.net/cgi-bin/bin/view/Main/WhyJavaGnome
there is a little paragraph about the advantages of java-gnome among
other libraries.

About the performance I think that now with native gcj compilation they
could be comparable. (still thinking that c++ bindings can be faster.)

Well, I've read these article very attentively. But it didn't tell me:
WHY I SHOULD USE JAVA-GNOME TO DEVELOP MY APPLICATION?
Here just the minuses: why should I leech to external native libraries
(libgnome and others)?
Just because java-gnome is good but <quote>Very few people say that

Swing with its MVC-architecture is well designed and formed
cross-platform library.
I think that in fact development of java-gnome is a sort of game. Very
interesting. But nobody need it really.

This might be a stupid question but are you sure you have a Main
method in the program??
Is it in the correct format(public static void main(String[] args) ??).
You can also check if you have a package decleration at the top of the
file indicatiing a path. That can cause problems too.

[Luca De R. <pie...@fa...>]

You need to add your current work directory to the classpath (as in
other java apps).
export CLASSPATH=3D.:/usr/share/java/gnome2.6.jar:/usr/share/java/gtk2.4.=
jar

Mark this should be in the HintsAndTips section.

Re: [Java-gnome-developer] Executing examples

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

you need to export the classpath and the LD_LIBRARY_PATH.=20
after:
smelc$ CLASSPATH=3D/usr/share/java/gtk2.4.jar:/usr/share/java/gnome2.6.jar

you need to do:
export CLASSPATH and the same with the LD_LIBRARY_PATH.
May I suggest adding these two to your .bashrc/.profile so that you
dont need to do this for every new session.

Re: [Java-gnome-developer] Executing examples

I tried to set both classpath and location of native part of the libraries but 
it didn't work :

smelc$ CLASSPATH=/usr/share/java/gtk2.4.jar:/usr/share/java/gnome2.6.jar

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

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

hi,
I tried using the Pixbuf instead of null but I still get the same result.
As for errors, if I use Program.initGnomeUI, I do not get any
errors/exceptions, however, when I use Gtk.init(args) to start the
application(in static main), I get the following error when I click on
the Help->About menu button:

ListenerDelegate.fireEvent(org.gnu.gtk.event.MenuItemEvent[source=org.gnu.gtk.ImageMenuItem@81c8408,id=ACTIVATE]):

I thought this was some sort of a listener error and that is when I
had added the MenuItemEvent parameter in the about method. Yet, that
does not seem to solve the problem.
Thanks for the help.

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

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

I'm not sure if this will help, but could you try adding  new
org.gnu.gdk.Pixbuf( "/usr/share/pixmaps/gnome-applications.png" ) (or any other
icon) in place of the null at the end of the call to new About(..). If this
fixes it, then there's a bug in our code. If it doesn't help, could you possibly
check for any warnings on the command line when you run it. The code looks
absolutely fine to me, so I'm not sure why it's not working.
