[Java-gnome-developer] Objects in TreeView

[Marc R. <mar...@gm...>]

Hi, is there any way to store actual objects in a TreeStore instead of 
the string value? For example, normally I call the setValue() method in 
the TreeStore, and pass in a tree iter, data column and string value. 
What I really want to do is stuff a set of objects in a Tree and be able 
to get the selected object back; somehow, a renderer somewhere would 
render the object to a string for displaying in the tree cell (similar 
to how swing works).

Is this possible?
Marc

Thanks all for your answers, finally i resolved it. It was a problem of 
glade3. I installed glade2 and do again the interface and all works fine.

Okay, where is libgladejni-2.12.so located on your computer? What is
the argument that you have specified in Eclipse's "VM Arguments"
textbox in your run configuration? Have you tried running your
application from the command line? Does it work? In Eclipse's "Debug"
view (Window -> Show View -> Other -> Debug -> Debug), right-click on
your terminated process, access its properties, what is the command
line argument?

I find this highly unlikely despite being out of the loop since September.

[Java-gnome-developer] Problems with Eclipse

[<pab...@ho...>]

Hello everybody,

I've installed recently ubuntu edgy.

Today, i have download all packages of java-gnome, and when i tried to 
develop and application (Eclipse + Glade) I've founded some problems. These 
are about the exception: java.lang.UnsatisfiedLinkError

I've put the string argument correctly like the example of java gnome web, 
but i obtained the error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: no gladejni-2.12 
in java.library.path
	at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1682)
	at java.lang.Runtime.loadLibrary0(Runtime.java:822)
	at java.lang.System.loadLibrary(System.java:993)
	at org.gnu.glade.LibGlade.<clinit>(LibGlade.java:262)
	at PruebaGlade.<init>(PruebaGlade.java:19)
	at PruebaGlade.main(PruebaGlade.java:32)

I've tried with different path like /usr/lib/ and /usr/lib/jni obtaining the 
same result.

Any body knows why it's happening? it could be a problem of new versions of 
java-gnome???

Hi Chris!

Welcome to the boat!

> Hello, my name is Chris. I am a CS student learning programming that finished the Data Stuctures class last using the Java language. I use Linux often and as my main OS. I found the Java Gnome project through Google, and now I want to get started. What should I read first? Should I read about gtk programming first? I thought it was used with the C language, so I will not understand it much. I have Eclipse IDE and Glade, and I watched the flash video. How do I get started? Thanks.

I recommend you to read some tutorials and documentation here:

  http://java-gnome.sourceforge.net/cgi-bin/bin/view/Main/HintsAndTips

Get a look on the javadoc too:

  http://java-gnome.sourceforge.net/docs/javadoc/index.html

I always use VIM for coding, btw I understand that most people will
prefer an IDE like eclipse with autocompletion and integrated javadoc.

Glade allows you to reduce drastically your LOCs and keep your software
easily maintainable and portable to other languages without huge effort.

So, I recommend you to start coding simple hello worlds with your
favorite editor, and later make use of a complete IDE that will make
you probably happier.

If you get the basics of the JavaGnome API you'll be able to develop
apps fastly without having to read javadoc or use autocompletion, because
most of it is bastly logical and easy to use. :)

Well, I think if you've seen the video, you should probably understand
how the bare basics work. There is some other documentation located at
our website [1] that may be of your interest.

I don't really know how to answer a "How do I get started?" since it's
a pretty broad question. For myself I started out using Glade and
tried to develop a little application. Best way to learn an API is to
try to use it, so I guess you could try starting off by mimicing an
application you've created with another widget toolkit from before or
if you've never done one before, try to mimic an existing application
that you currently use.

Incidentally, one of the things I've been leaning towards adding in 4.0
is a Glib.init(). There isn't such a thing in as g_init() of course
(although one DOES have to call g_type_init() if using gobject et al and
even though gtk_init() does that for you I'm doing it explicitly much
earlier in the execution path) but for the case where you're not
actually using GTK it is a but strange to have to fire it up in your
code.

And the main loop is a GLib construct, after all.

So maybe we'll expose a GLib.main() but block its use if Gtk.init() /
Gtk.main() have been used.

The other possibility is to do it on library load automatically. Still
fiddling. I'll write an email to -hackers when something concrete
precipitates out.

I tried linking the java-gnome jni.so libraries into my executable once,
but I couldn't get it to work. If I had to guess, it's because
System.loadLibrary() seems to require that there be a separate library
be findable by dlopen() at runtime by name.

You'd think, though, that libgcj would have hacked theirs up so that it
could find its symbols linked in to the final binary. Maybe someone
smarter than me can point out how to do it right.

Interestingly, although the library as a whole gets loaded, Sun's JVM
does the symbol lookups on a class by class basis. Try

	java -verbose:jni MyProgram

sometime. And try doing

	ldd ./myprogram

on a java-gnome binary built with GCJ. It's quite the monster list, so
somehow removing the JNI .so's wouldn't really change much.

Be aware that Ubuntu is out of date:
https://launchpad.net/distros/ubuntu/+source/glib-java/+bug/70113/
so Ubuntu users need to show some of that Ubuntu magic that Ubuntu
lovers are always going on about and get some new java-gnome packages
made up!

I'm sorry, I really don't know about that one.  I don't think one can
get rid of the JNI library requirements without actually linking in all
of them as well.  I still don't understand how your gcj invocation above
is working.  Don't you need -findirect-dispatch if you're using
the .jar.so files?

Yeah, that sounds fishy to me.

Re: [Java-gnome-developer] undefined reference to `org::gnu::gtk::Entry::class$'

[Jean-Christian de R. <jc...@ec...>]

Thanks for you response, I did't know about the ABI species.

I finally get my stuff working, but the result raised two new questions:


1) I did not success removing completely the JNI stuff. For exemple I=20
can compile fine with the following command an application that only use=20
GTK:

gcj --classpath=3D/usr/share/java/gtk2-10.jar:/usr/share/java/glib0.4=20
/usr/lib/gcj/gtk2.10.jar.so /usr/lib/gcj/glib0.4.jar.so=20
--main=3Dch.eclis.ch.test.Simple -o Simple src/ch/eclis/test/Simple.java

But it run fine only if I use the command:

LD_LIBRARY_PATH+=3D/usr/lib/jni ./Simple

Without the LD_LIBRARY_PATH I get this message:

Exception in thread "main" java.lang.UnsatisfiedLinkError:=20
libgtkjni-2.10: libglibjni-0.4.so cannot open shared object file: No=20
such file or directory

I did not understand why the GCJ library still make the JNI stuff=20
required. I that normal or I still make someting wrong ?


2) If I understand correctly the packages that provids a GCJ library=20
have to install at least 2 files: a classmap *.db file (under=20
/usr/share/gcj/classmap.d/ on the Ubuntu Edgy) and a library *.jar.so=20
file (under /uar/lib/gcj/ on the Ubuntu Edgy). This is at least what I=20
can see in all packages I have, with the exception of the=20
libglade-java-gcj package that install a classmap *.db file but no=20
library *.jar.so file at all. This sound very strange to me because the=20
classmap point to a /usr/lib/gcj/glade2.12.jar.so file that is not=20
included into the libglade-java-gcj package.

This can be a Ubuntu Edgy specific issue. But I want to know if there is=20
something special I did't understand or if this is a real issue.


Thanks,

Yep, that was it. Wrapping the code with Gtk.init() / Gtk.main() makes
it work as expected.

Probably not. That code was written several years ago by {Jeff?} and I
don't think anyone has touched it since. I'm glad to hear that at least
getting works.

Did you try looking at the example code in libgconf-java/doc/examples ?

If you figure it out and want to contribute a patch, or need to talk
about the internal details of the present 2.x code, then by all means
come up on java-gnome-hackers or #java-gnome

I've not tried, but I'd expect that this is integrated with the glib

[Java-gnome-developer] Problem getting change notifications from GConf

[Pierre-Charles D. <pc...@gm...>]

Hi all,

I'm trying to use the gconf bindings (libgconf-java-2.12.5) from Java.
It works well when requesting values, but I can't seem to get
notifications of changes. I'm new both to java-gnome and gconf itself,
so I may be missing something obvious.

Below is the code I am running. While it is waiting on the last line,
I run gconf-editor and manually change the (boolean) value of the key
"/apps/baobab/properties/enable_home_monitor"; I was expecting my
listener to be called, but it is not. Am I doing something wrong /
misunderstanding gconf, or is this feature not supported yet?

Thanks in advance.

    public static void main(String[] args) throws Exception {
        ConfClient cc = ConfClient.getInstance();
        cc.addDirectory("/apps/baobab/properties",
ConfClientPreloadType.RECURSIVE);
        System.out.println(cc.get("/apps/baobab/properties/enable_home_monitor"));
        cc.addListener(new ConfClientListener() {
            public void clientNotify(ConfEntry entry) {
                System.out.println(entry.getKey() + " = " + entry.getValue());
            }
        }, "/apps/baobab/properties");

[Java-gnome-developer] ComboBoxEntry and ClassCastException

[Marco A. P. S. <map...@gm...>]

Hi,

I'm just starting with Java-Gnome and GTK, and I have some questions about
ComboBoxEntry.
I'm developing an application in wich I would do the following:

1) clear the text in the Entry associated with the ComboBoxEntry when the
user clicks a button
2) prevent the user from directly edit the Entry associated with that
ComboBox (setting that Entry "editable" property to false)

In order to do number 1 above, I've tried to do the following:

Entry entry= (Entry) (combo_box_entry.getChild());
entry.setText("");

which yelds a ClassCastException in the first line.
Am I doing something wrong? I've read somewhere that ComboBox is a Bin, and
thus it's child Entry is available through getChild()...is this right?

Any help is appreciated. Thanks in advance!

You're mixing the old C++ ABI and the new BC-ABI.   The .jar.so file is
a BC-ABI .so.  You'll need to add -findirect-dispatch to your
compilation line to make that work.  However, you should probably read
about the BC-ABI and gcj-dbtool.  I don't have any pointers OTTOMH, but
google should probably find some stuff.

Now I try to compile the application to get a native ELF executable but
after several test, I still can't reach this goal. The most advanced
result I have is with the following command:

collect2: ld returned 1 exit status

Using -fjni option give the same result. I have found the symbol
_ZN3org3gnu3gtk5Entry7class$$E in the /usr/lib/gcj/gtk2.10.jar.so, are
the one supposed to match the org::gnu::gtk::Entry::class$ ? As for the
glade symbols, I didn't find a glade*.jar.so or something like this.

Thanks in advance to any help,

Re: [Java-gnome-developer] Glade forms

Hi Marc,

Note that I haven't programmed in Swing in a long time, so I may be
out of context here.

You have to handle the LifeCycleEvent of the Window. I believe you
capture the DELETE and DESTROY events and then return false? Or maybe
it's true? Well, either one of them should prevent your gtk window
from being disposed. I think later you have to call showAll() or maybe
setVisible(true) to bring it up? Sorry, I haven't really programmed in
JG for a while. :/

There should a 'visible' property in the 'properties' dialog for you
to tweak this if I recall correctly. I have not used Glade in over a
year and a half or so, but it's somewhere in there. So if you set it
to false it's not going to appear upon application startup.

Regards,
Rem

[Java-gnome-developer] Glade forms

[Marc R. <ma...@sh...>]

Hi, I am new java gnome; it looks very interesting and I've decided to 
try it out. One of my questions is how do you create an instance of a 
Form. I designed it all in glade of course, but as soon as I run the 
program and load the glade file, _all_ of the forms I designed become 
visible (??) without me activating them in any way. If I close the 
forms, I can no longer show them by doing "form.show()" because the form 
has been disposed.

In swing, you do something like

JFrame frame = new MyForm1();
frame.setVisible(true);
....
frame.dispose();

and later on again, I can do that same code without any problems. Is 
there a similar mechanism using glade, or what is the recommended way of 
dealing with calling the same form multiple times. Also, how do you stop 
them all from appearing when I load the glade file.

Thanks for your time,
Marc

[Java-gnome-developer] Question about destroy

[Marek P. <mc...@o2...>]

Hello.

Could you help me with my problem?

I have a cairo drawn custom widget based on gtk.DrawingArea and
it hangs my app on closing if i don't execute withdraw() on its
gdk.Window.

What is the best way to do some custom things with widget on closing?
Send message to it by java.util.Observer? Or is there a better
way?

Thanks.
Marek
