[Java-gnome-developer] big problems with glade

[Rafael F. <ra...@op...>]

Hey everyone, 

sorry if this a stupid question but I get this crazy error:

(process:8475): GLib-GObject-CRITICAL **: gtype.c:2253: initialization
assertion failed, use g_type_init() prior to this function

(process:8475): GLib-GObject-CRITICAL **: file gobject.c: line 819

(process:8475): GLib-GObject-CRITICAL **: file gobject.c: line 1579

	at org.ophion.jyum.JyumGui.<init>(JyumGui.java:36)
	at org.ophion.jyum.Jyum.main(Jyum.java:22)

whenever I instanciate a new object of the type below:

public final class JyumGui {

    private LibGlade gladexml; 
    private final String XML = "/home/rafael/dev/Jyum/glade/gyum.glade";
    private final String XML_ROOT = "Jyum";
    private static final String PROGRAM_NAME="Jyum";
    private static final String PROGRAM_VERSION = "0.001";
    
/* 
 * Constructor
 */    
    public JyumGui() {
           
        try {
            gladexml = new LibGlade(XML,this,XML_ROOT);
            
        } catch (GladeXMLException e) 
        { 
            e.printStackTrace();
            System.exit(-1); 
        } catch (FileNotFoundException e) {
            e.printStackTrace(); System.exit(-1);
        } catch (IOException e) {
            e.printStackTrace();
            System.exit(-1);
        }
        System.out.println("gui ctor");
        
        Program.initGnomeUI(PROGRAM_NAME, PROGRAM_VERSION,null);
        Gtk.main();
     }
    
    
    /*
     * Listeners
     */ 
    public void on_about1_activate()
    {
        String  documenters[] = new String[1];
        documenters[0] ="Rafael Ferreira";
        
        About about = new About("Jyum","0.1","GPL","The Java yum
interface",documenters, documenters , null ,null);
        about.show();
    }
    
    public static void main(String[] args) {
    }
}

* All that I'm doing is a new JymGui(); call in another file... any
ideas??

thanks, 

- Rafael

I'm not sure, but you might try moving the Program.init call before the
try/catch block (i.e. before calling "new LibGlade").

[Java-gnome-developer] Backport of libgnome 2.8 - please test!

[Joao V. <jvi...@ya...>]

I've made a backport of libgnome-2.8.2 to run on Gnome 2.6. Basically what i did was to remove all
2.8-specific calls (which strangenly weren't many: just 2), and compile it on Gnome 2.6.

It compiled fine, and i ran a gnome HelloWorld just fine. But, we can't make this official because
we don't know exactly how good this backport is, if there's some problem, etc.

*So*, here's what i'm doing: i'm making the backport avaliable to allow people to test it. I've
packaged it with autopackage, you may download it here:

http://www.angelfire.com/linux/jvic/libgnome-java-2.8.2.x86.package

To install:
 * Download (you may have to 'right click->Save link...')
 * Make it executable
 * Double-click it, it will install it.

To see the files installed:
 $ package files libgnome-java

I have also made a patch avaliable, for the ones who want to build it, or to see what were the
changes. Here's the patch:
http://www.angelfire.com/linux/jvic/libgnomebackport.patch

That's basically that; please test and send feedback.

Oh, if you're wondering why i've backported it: i believe there's still many people on Gnome 2.6,
and i'd like to make Java-Gnome avaliable for this people too. Mdk, for example, is still on Gnome
2.6 and will be till July probably. And even when it releases a new version, many ppl won't
upgrade immediately. There's also a lot of ppl still using Fedora 2. So, that was the reason,
basically.

Cheers!
J.V.
