Thanks for looking into this. Is there anything else I need to apply
other than these 2? I am still having the same problems. I will try to
make a standalone test case in a bit.

Perhaps you are right.  I view this as a coding error on my
part and a bug on Sun's part.  I would hate to see gcj implement
all of Sun's bugs! 8-)

If Sun's JVM accepts this, and libgcj doesn't, then there is some 
argument for gcj to support it too. No doubt there'll be some 
application out there that relies on it.

Re: [Java-gnome-developer] Assertion failure while drawing on DrawingArea

[Jeff M. <ku...@gm...>]

I do have some good news for you.   There have been many bugs
fixed in the latest cvs.  I just ran your example and it works without
the crash.  In fact, it is now in our cvs.  If you are runing the HEAD
you should be able to create your DrawingArea now.  If you are using
anonymous cvs you may have to wait until tomorrow for all of the
fixes to appear.

[Jeff M. <ku...@gm...>]

Mark,

There is one strange issue that I am unable to understand.  Our
textbuffer.TextBuffer example compiles and runs under kaffe
and Sun's JDK but crashes under gij.  It doesn't print a stacktrace.
It just prints "Aborted".  Have you seen this before?

Re: [Java-gnome-developer] Re: java.lang.ClassNotFoundException: Lorg.gnu.glib.Handle32Bits;

[Jeff M. <ku...@gm...>]

Mark,

It was a silly error.  The call to FindClass was as follows:

(*env)->FindClass(env, "L/org/gnu/glib/Handle;");

The leading 'L' and trailing ';' were causing the problem.

Do you have an example of such a wrong call?
Maybe we can improve the way FindClass handles this to give better
diagnostics of the problem.

This error has been fixed and is in cvs.  The two files updated are
org.gnu.gtk.Widget.java and org_gnu_glib_GObject.c.  The changes
are quite small and you might be able to apply the changes yourself
if you do not wish to wait for anoncvs to sync.  Here are the diffs:

http://cvs.gnome.org/viewcvs/java-gnome/libgtk-java/src/jni/org_gnu_glib_GObject.c?r1=1.33&r2=1.34
http://cvs.gnome.org/viewcvs/java-gnome/libgtk-java/src/java/org/gnu/gtk/Widget.java?r1=1.77&r2=1.78

I thank you very much for your bug reports and appologize for the problems
you are having.  There have been many changes lately and we are in the
process of tracking down all remaining bugs.  You have helped by point out
two!

[Java-gnome-developer] eclipse plugin?

Does anybody know what happened to the eclipse plugin?  It would be
nice the find the existing code and re-establish the effort.

That is a good question.  I still have to write the presentation and soon.
I am open to ideas!

There are going to be many people from other open source java
projects like classpath, gcj, kaffe,  Red Hat's awt/swing effort,
and ikvm.net.  I am sure there will be a lot of discussion about the
current state of open source java and where it is going.

I am going to be speaking about java-gnome at FOSDEM in
Brussels Belgium on February 26th.  Many open source
java projects will also be presenting there and it should
be a great time.  If you are able to attend I look forward to 
meeting you there.

If you are using anonymous cvs then you need to wait until tomorrow. 
Gnome anonymous cvs runs as much as 24 hours behind the regular
cvs.

This should be fixed in the cvs head now.  Funny, a call to FindClass
was made with incorrect parameters and failed with gcj and kaffe but
worked with Sun's JDK.  Anyway, it now works with all jvms.

[Java-gnome-developer] Re: java.lang.ClassNotFoundException: Lorg.gnu.glib.Handle32Bits;

[Ka-Hing C. <ka...@gm...>]

Interesting thing is, if I try to call new Handle32Bits() in main,
both IBM's runtime and gij runs fine, but with gcj I get a
NullPointerException when the constructor is called:

Exception in thread "main" java.lang.NullPointerException
   at java.lang.Class.initializeClass() (/usr/lib/libgcj.so.5.0.0)

[Java-gnome-developer] java.lang.ClassNotFoundException: Lorg.gnu.glib.Handle32Bits;

[Ka-Hing C. <ka...@gm...>]

Using libgtk-java 2.5.3 or cvs HEAD, the above exception is thrown
whenever I call the constructor of any org.gnu.gtk.* class. Tried with
IBM's powerpc 1.4.2 runtime as well as gcj (3.4, both by compiling to
native code or using gij).

For example, this is my main:

Gtk.init(args);
org.gnu.gtk.Window win = new org.gnu.gtk.Window(WindowType.TOPLEVEL);
win.showAll();
Gtk.main();

Here's the trace:

Re: [Java-gnome-developer] libtgtk-java refresh?

[Benjamin P. J. <bp...@gm...>]

Replace the line that reads:
  label.setText("after");

It should be sth. like that:
  org.gnu.glib.CustomEvents.addEvent(new Runnable() {
    public void run() {
      label.setText("after");
    }
  });

Cheers!
  Benjamin

[Java-gnome-developer] Article: "Stop Saying 'Our Implementation Is Open Source,' It Is Not"

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

Very good article!

http://www.sys-con.com/story/?storyid=47603&DE=1

"Stop saying that 'Java is not Open Source,' and realize that 'Sun's 
implementation is not open
source.' Even better, stop saying that 'Our implementation is open 
source,' it is not you know
that, and this is OK, we're not blaming you, we want to work with you." 
As part of our end of year
round-up of the Best of 2004, read Bruno Souza's answers to Sun's Onno 
Kluyt, who earlier this
year asked what the open-sourcing of Java would make possible that 
people can't already do today
with Java (...)"

Cheers,
J.V.

[Java-gnome-developer] libtgtk-java refresh?

[Abcdefg <ab...@so...>]

Hi,

I'm creating a Gtk program (not Gnome) but I have a problem that stuff
doesn't refresh until I move my mouse over the window. It's hard to explain
the problem so here's an example program.

import org.gnu.gtk.*;

public class Test extends Thread {
Label label;

public static void main (String arg[]) {
Gtk.init(arg);
new Test();
Gtk.main();
}

public Test() {
Window window = new Window(WindowType.TOPLEVEL);
label = new Label("bevore");
window.add(label);
window.showAll();
start();
}

public void run() {
try {
sleep(1000);
} catch(InterruptedException e) {
}
label.setText("after");
//refresh?
}
}

The text "after" only show up after I move the mouse over the window and not
after 1 second. Do I have to add some refresh line or something? Or am I
doing something else wrong (I don't need App do I?) This happens for
everything I tried (labels, buttons, progressBar)

Thanks and happy new year ;)
David

Re: [Java-gnome-developer] FileChooserDialog Questions

[Skip C. <sco...@gm...>]

Hey there, 

Thanks.  I have FileChooserDialog sort of working with glade now.  I
am wondering if anyone has noticed that the buttons do not appear when
the dialog is shown.  I can add the buttons with addButton().  When I
manually add the buttons, I don't know how to tell which button was
pushed by the user.  Anyone have any suggestions.
