Is that really the only error you get?
What version of aclocal and autoconf are you using?

I'm not quite sure what you mean by this? Are you saying that the example
doesn't work unless you have a call to getWidget in the code (even if you don't
use it)?

Well, I've been trying to do some work on the gtkhtml2 bindings, but 
have been stalled due to personal schedule overload.  I can try to take 
a look at this later today... I hope. :)

[Java-gnome-developer] Making native binaries

[Thomas P. <per...@ao...>]

Hello, List!

I'm currently developing a GUI for FunkyMD using java-gnome (the libgtk-
java thing actually only).

As I don't want to require ALL users who just want to run the program
but are not motivated to download and install java-gnome, I want to
compile my java code into a native linux binary.

I've tried this with gcj, and it looks like it is working somehow.

Can somebody come up with a step-by-step instruction on how to compile a
java-gnome application "right" and how to deploy it then? (statically
linked executable?, putting libs into the package? which libs?)

Thanks for all information!
Thomas Perl

[Java-gnome-developer] configure problem with CVS version.

[Nicholas R. <ni...@mn...>]

I've been having problems trying to compile java-gnome from source.  I
have tried both the 2.7.4 tarball and the CVS version (by hand and via
jhbuild).  Here's what i get when running configure in libgtk-java:

me: /usr/local/src/java-gnome/libgtk-java> ./configure

when running autogen.sh i get this:

me: /usr/local/src/java-gnome/libgtk-java> ./autogen.sh
Illegal variable name.

can anyone point me in the right direction?
thanks in advance for your help,
Nick

[Java-gnome-developer] Re: ImageMenuItem without a stockid

[Jeffrey M. <jef...@br...>]

You are right.  Please replace the getImage method with:

        public Image getImage() {
            int hndl = gtk_image_menu_item_get_image(getHandle());
            if (0 == hndl)
                return null;
            GObject obj = retrieveGObject(hndl);
            if (null != obj)
                return (Image)obj;
            return new Image(hndl);
        }

This method will cache the image the first time and return
the cached version on subsequent calls.

	public void setImage(Image image) {

	}
	
	public Image getImage() {
	    int hndl = gtk_image_menu_item_get_image(getHandle());
	    if (hndl > 0)
	        return new Image(hndl);
	    return null;
	}

This is going to return a new Image instance each time you call
getImage(), and it may fail since a handle can be negative, but I see
the point. Thanks.

RE: [Java-gnome-developer] ImageMenuItem without a stockid

[Jeffrey M. <Jef...@Br...>]

This is a current limitation of the bindings.  The gtk library
has methods to set and get an Image.  Please open a bug against
the bindings.  We will be starting our 2.9 development effort
in the next week or so and I can quickly add this capability.  If
you want the feature now you can just past the following code
into the ImageMenuItem.java file above the declaration of the
native methods.

	public void setImage(Image image) {
	    gtk_image_menu_item_set_image(getHandle(), image.getHandle());
	}
	
	public Image getImage() {
	    int hndl = gtk_image_menu_item_get_image(getHandle());
	    if (hndl > 0)
	        return new Image(hndl);
	    return null;
	}

I think what is happening in that particular example (and the reason you
don't have any getWidget()s in the code and yet it still works) is that
the glade file used in the example defined the callback functions it
needed and so libglade would auto attach them with those found in the
java code. Now, you still have to getWidget() if you want to do any kind
of widget manipulation cause the only things auto connected are
callbacks (which libglade will complain about if they don't exist in
your code).

If I recall this one is one of those gnome issues. There are special
"helper" classes for the Appbar, as it's called in libgnome-java, to
help you get the statusbar. I'd suggest reading the libgnome-java
javadocs a couple of times... It took me more than a couple times to get
it the first time...

You can use jhbuild if we want, see the Hints and Tips sec. on the site.
Probably all the problems you've experienced with java-gnome-2-6 will go
away.

That's the normal behaviour and a common problem. Set the windows
visibility on *glade* to hidden and it should be fixed.

Re: [Java-gnome-developer] UnsatisfiedLinkError on HTMLDocument ( html_document_new)

[Nicholas R. <ni...@mn...>]

Thanks for the info.

It is quite strange.  Here's a small test program that shows the
problem.

import java.io.IOException;
import java.net.MalformedURLException;
import org.gnu.gnome.App;
import org.gnu.gnome.Program;
import org.gnu.gtk.Gtk;
import org.gnu.gtk.ScrolledWindow;
import org.gnu.gtkhtml.HTMLDocument;
import org.gnu.gtkhtml.HTMLView;

public class TestHTML {

    public static void main( String[] argv ) {
        // Initialization
        Program.initGnomeUI("First", "0.1", argv);

        App app = new App("First", "First App");
        app.show();

        HTMLDocument document = new HTMLDocument();
        HTMLView view = new HTMLView();
        ScrolledWindow sw = new ScrolledWindow();
        sw.add( view );
        try {
            document.loadURL( "http://www.google.com" );
            view.setDocument( document );
        } catch( MalformedURLException ex ) {
            System.err.println( ex );
        } catch( IOException ex ) {
            System.err.println( ex );
        }

        Gtk.main();
    }
}

I compile and run this (with Java 1.4.2 or 1.5) and i get the following
exception:

Exception in thread "main" java.lang.UnsatisfiedLinkError:
html_document_new
        at org.gnu.gtkhtml.HTMLDocument.html_document_new(Native Method)
        at org.gnu.gtkhtml.HTMLDocument.<init>(HTMLDocument.java:44)
        at TestHTML.main(TestHTML.java:19)

I then run it with strace to see what's going on and i can see that it
is loading the correct library, but the UnsatisfiedLinkError is raised
just after the load.  However, if i run nm on my library, i can see that
the above mentioned function is in the library.

i thought then that it might be my compile of the libgtkhtml-2.6.2
library, so i re-emerged it.  didn't work.  then i compliled it by hand
into /usr/local.  still the same error.

perhaps if there's some other gentooers out there (with a standard
gentoo setup) they could try out the little program above and see what
happens.  i'll probably also post to the gentoo forum to see if anyone
there has had a similar experience.

As for a 2.8 ebuild, let me know if you want some help with testing.
Currently, I'm trying to get the CVS version of java-gnome installed,
hoping i'll have better luck with that (i have gnome 2.8 installed
already as it's in gentoo's ~x86).

Re: [Java-gnome-developer] StatusBar issue + 2 questions

[Fred B. <cha...@ma...>]

thanks :)

1) yup, I had noticed for the callbacks.. nifty thing. Didn't realize it
wouldn't get the whole thing :\

2) Doh me! I was just getWidget() on the window, then hide() it.. that's
better though.

3) I will read up more for the StatusBar.

[Java-gnome-developer] StatusBar issue + 2 questions

[Fred B. <cha...@ma...>]

Hello all

I am using the 2.6 libs from debian unstable. I am using eclipse 3.0 for
my IDE.

Questions first:
1) I have created a Window with glade, and I am tying it in my java code
via LibGlade. No problem thus far, except that I don't understand that
example
(http://cvs.gnome.org/viewcvs/java-gnome/libglade-java/doc/examples/glade/LibGladeTest.java?rev=1.8&view=markup)

I have tried it in my own code, but with no success. I have to do
something like the following to be able to do something with my widgets:

gladeXml = new LibGlade("/home/fblaise/Glade/jgLDAP/jgldap.glade",this);
cboExistingConn = (ComboBox)gladeXml.getWidget("cboExistingConn");

If I don't getWidget() my object like this second line shows, despite
the fact my widget has the same name in Glade and in my code, I just get
a NullPointerException when I invoke anything on it. If anyone can shade
some light.. I guess it'd very cool to not manually map each widget, and
let LibGlade do it for you.

2) My glade project includes several windows. All my windows pop up when
I start the program. Is there anyway to prevent that? 

3) The StatusBar problem:
When I try to map my status bar like this:

statbar1 = (StatusBar)gladeXml.getWidget("statbar1");

It tells me this:
could not create widget: org.gnu.gtk.Statusbar


Thanks :)

[Java-gnome-developer] ImageMenuItem without a stockid

Hello,

I can't find a way to create an ImageMenuItem with an image of my
own. Is it a current limitation or did I miss something in the docs ?

Yes, I have...

...er,  I just reconsidered the question and realized that of course I'm
running from CVS and have an entire Gnome installation in /opt/gnome2
and that's what I'm linking against.

Nicholas, java-gnome 2.8 has a considerably re-arranged internal layout
and my experience has been that it works whereas I had trouble with 2.6=20

I promise when 2.8.x is stable I'll get an ebuild out - in fact I'm
becoming a Gentoo developer presently largely so I can take care of the
java-gnome ebuild.

I have it working on fedora, however the html example works with local
file, but crashes with an "java.io.IOException: Malformed HTTP header"
when trying to load an online web page.

If you want to do fundamental changes, is better to ask before. (you can
have a discussion directly on the wiki pages).

However take a twiki account and make your changes, no-one is going to
stop you :)=20

You don't need approval, just edit the pages, or add new ones. We want to try to
fill the website with useful, up to date, hints and tips so we just let anybody
and everybody modify it. We do keep all old versions and keep track of changes
just in case anything goes wrong, but we don't expect that to be the case.

Sounds like it could be a problem with the way it was compiled. Has anyone else

Let me clarify that.. I read how to do on typing in the wiki in

what i meant was more along the lines of: Do I need to post here before
posting on the wiki to get approval, or stuff like that?

[Java-gnome-developer] wiki - EclipseDevelopment

[Fred B. <cha...@ma...>]

Hello

I would like to modify the wiki here:
http://java-gnome.sourceforge.net/cgi-bin/bin/view/Main/EclipseDevelopment

to explain how to set up the java.library.path from inside a project in
eclipse, without going through a shell script.

What is the procedure? It would be my first time doing something with a
wiki :)

thanks
