[Java-gnome-developer] Possibility to built SWING on top uf Java-GTK?

[Linuxhippy <lin...@we...>]

Hi there again!

My laptop is still broken, I write this mail with my old 15´ 60Hz 
Monotir ;-)

Very often I hear about OpenSource-VMs like Kaffe, GCJ, ORP and many others.
Many oft them are supporting AWT none of them have builtin-support for 
SWING.

My IDEA (its only an idea!) is, to make not the same fault as SUN did 
with SWING (althought SWING is not bad, but its really slow and does 
absolutly not integrate in the native gui-interface).
I thought that it should be possible  to reinvent SWING an the top of a 
native gui-toolkit, but I want to ask you here, because of here are the 
real gui-gurus! (especally Jeff!!!)
This implementation does not need to be exatly 100% compytible, I know 
this is not possible....


So please let me ask some questions relating to this theme:

1.) Would it be possible to use Java-GTK as the underlaying "platform".
I know many things need to be reinvented in SWING style, but its better 
to code SWING in a "high-level-way" with java-gtk than dealing with 
native funktions.
java-gtk does so many nice things for me (e.g. Memory handling), that I 
think it would be much easier to start with jgtk than from scratch...

2.) What about events and layouts?
a) Would it be possible to widly emulate swing event, using and 
extending the current java-gtk event-model?
b)How would it be possible to recode the swing-layouts using java-gtk. I 
know that swt has realized some java-like layouts using gtk...
Would it be possible too rebuild all the layout-managers using a 
gtk-layout with fixed position?
Would it be possible with boxes and tables?

3.)Is it important to rebuild exactly that heredity-hirachy (I´m sorry 
for my bad english, I know that word is wrong..) like sun does in swing?


I know I not experienced with both Java/JNI/java-gtk enough to start a 
such project, but so many people are asking, and nobody does begin.
This really bothers me so much, so that I want to start. I know I´m 
always a little bit rash, but so I´m ;-)
I want to start this project, if its possible in most parts. I know its 
a very big amount of work, SWING is very big and SUN did not design 
SWING to be easy portable to native guis. But I´ve heard of a 
static-win32 Java-Compilier which translates SWING to native 
MFC-Programs, so its theoretical possible!


Good luck again, Clemens

PS: I was able to built Java-GTK on Windows using Cygwin.
Hmm, but thats quite a very dirty port. It still requires an X-Server.
The whole libraries (without the X-Server) are around ~20Mb (only GTK2, 
Pango, ZLIB.......).

Hi Mark

I asure you gtk.jar and gnome.jar are in ther correct paths. The lib file=
s are also ok. Some examples compile and run fine, but others don't. I go=
t the tutorial from the website. The First.java example compiles and work=
s ok. The Second.java and Third.java are also fine. But the Fourth.java s=
ends me the following messagens when compiling:

chacal@Insanidade:~/progJava/GTK$ javac Fourth.java

[Java-gnome-developer] Code in CVS

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

Hi, 
  For using the code in CVS:

1) Checkout the java-gnome module from the cvs repository. Details can
be found at http://sourceforge.net/cvs/?group_id=1522

2) run ./configure to set up Make files

3) run Make. This will compile the libraries, producing shared libraries
(.so files) and java bytecode in jar files. These will all be placed in
the java-gnome-dir/lib directory.

Example applications can be found in src/examples/[gtk|gnome|..].

Before using them, you must set up your environment:
export LD_LIBRARY_PATH=/path-to-java-gnome/lib/   -this will make the
system search here for the shared libraries.
export
CLASSPATH=/path-to-jg/lib/gtk.jar:/path-to-jg/lib/gnome.jar:$CLASSPATH 
-this will allow java to find the java bytecode.

then compile the example, e.g.
javac buttonbox/ButtonBoxes.java
and run:
java buttonbox/ButtonBoxes

Hope that helps.

I get this erros messagens when compiling some of the examples from the C=
VS repository:

FileEntryTest.java:6: package org.gnu.gnome does not exist
import org.gnu.gnome.Program;
                     ^

Mark Howard has told me some has changed since last java-gnome released v=

Have you set the LD_LIBRARY_PATH to the library? I don't know what the
GTKJava library is called (I guess libGTKJava.so), find the path where
it lives, then:

export LD_LIBRARY_PATH=3D/path/where/lib/is/

Yes, there's lots of ppl here. 
We were quite confused with your previous message with subject send
messagens. Hopefully you have now discovered how to subscribe properly (
https://lists.sourceforge.net/lists/listinfo/java-gnome-developer)

Java-Gnome is currently been rewritten for GTK+2. Our efforts so far are
available in CVS. These do work, however they are as of yet incomplete -
that's why we haven't released them officially as 0.8.0.

On the website, you may also download version 0.7. This is an old
version based on GTK1.2. This is obsolete and we highly recommend that
it is not used.

I believe the problem you are encountering is that you are trying to run
one of the java-gnome 0.7 tutorial applications using the latest code
from cvs. This will not work as much has changed since 0.7.

If you do want to try out the latest code, many of the examples in cvs
(in the src/examples directories) do work. At present, however, there is
no tutorial for the latest code. Documentation exists only in the form
of API references produced by javadoc.

Hmm, I tried this Method when the widget was stored in a hbox, but it

It seems you are supposed to use pointer type and set the pointer to a
gdk pixbuf - but this all means c pointers, not java pointers. I have
modified the glib and tree files so this should now be possible in
java-gnome. However, the required gdk.Pixbuf classes haven't been
implemented yet. 
I've just been looking at the docs and it seems like these are huge
classes, so it may be a while before they are complete.

Pango markup tags don't apply for alignment. They're used for things
like fonts and colours.

There is a pango attribute for alignment, however you should rarely need
to use this as many widgets will provide their own method for aligning
text.

In a label widget, for example, you can use the
setJustification(Justification.CENTER ) method.

[Java-gnome-developer] Can't catch a clicked event of FileSelector

[FORT D. <pop...@fr...>]

The example of FileSelector doesn't catch the clicked signal of the Ok button,
and i have the impression that it's because in GTK2.0 the signal registration
is dynamic. In org.gnu.gtk.event.ButtonEvent types of signal are allocated
as 1, 2, 3... were they should be get by using g_signal_lookup. My impression
is that if buttons are created first everything is fine because signals are
registered in the expected order, but in the FileSelectionBox the Gtk core 
registers other signal before registering the signal for Button, so it's not
anymore 1, 2, 3.... And finally as the signal aren't registered correctly the
corresponding callbacks are never called.

Please correct me if i'm wrong, and consider telling me "It's late your should 
be sleeping, or please drink another cup of coffee".

I *think* that you are supposed to use a string, containing the filename
of the image.

Unfortunately, I haven't tested all features of the tree widgets in
great detail, so cannot give exact details. As previously said, this is
work in progress, so should improve with time. If you have any specific
suggestions for how we can make improvements, please give them. 

Good luck!

I dont wont to give up, dont worry. I want to produce a mainstream-app usi=
ng Java-GTK and GCJ, two technics whch are not very common, but great. Hmm=
, I dont have the choice, because SWT doesnt understand GC, so its out of =
the race ;-)

May I ask one question: The store needs an array with types of the type Ty=

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

I couldn't agree with you more.  Our first pass is just an
attempt to wrap the widget as it exists in the native library
to make sure we can get all of the functionality working
properly.  We are not quite there yet.  Once we get this working
well we will probably try to create a higher level wrapper
that will hide much of this complexity (much like we did with
the list widget).

Please don't give up on us just yet.  We are working very
hard to fix the current problems.  We will be addressing
the complexity of these libraries over time.  We will also
be providing more documentation as time goes on.  Your
input will help us make this better.

No such type.... Re: [Java-gnome-developer] Tree-Widget with Pixmaps at the nodes?

[Linuxhippy <lin...@we...>]

Hi!

I´ve read alle the examples, and wow, this widget isnt easy.

My problem is, that I need to create a TreeStore  with Objects defined 
in Class Type...
But which Object is an Image? - Is it O.K. to use a Image, I dindt find 
any useful Pixbuf-stuff
I tried it with several types, but I only became this:

(java-gnome:1653): Gtk-WARNING **: gtktreestore.c:801: Unable to convert 
from gpointer to GObject

I´m really frustrated, I want to learn Java-GTK, but some parts are so 
counterintuitive, I dont really understand this widget..

Has anybody already written an app using images in Treeview? Some 
sourcecode would help extremly....

Sorry, but I really, really read very much documentation...

thx Linuxhippy

Only one short questions..:

How can I make the text of a widget right-alligned, i read that i=B4ve to wo=
rk with pango-tags, and I looked at the pango-site, but I dont understand =
anything....
Only a very short answer would do it, so I dont waste too much of your tim=

RE: Java-Bonobo integration [was Re: [Java-gnome-developer] Gnome 2 for Solaris DE]

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

This is very good news.  I a future version of the bindings
we hope to provide bonobo integration.  At that time I would
like to talk to you in detail about this code.  Currently we
are trying to stabilize the bindings after a major rewrite
so we can produce our next release.

Why, I dont understand. As far as I know, java-gnome was made for people w=
ho doesnt like SWING or have already coded in GTK+ and want to use the adv=
anced language-features of Java.
The main-goal of java-gnome is not to provide a java/gnome integrations, i=
t was made (as far as I know!) to let programmers code in a great language=
 and have a fast, native gui!

Java-Bonobo integration [was Re: [Java-gnome-developer] Gnome2 for Solaris DE]

The only other work that I am personally aware of is java-bonobo
integration work.  The work in that area that I am aware of is public,
and personally I think it may be more promising for general java/GNOME
integration for some projects than the java/gtk+ bindings that this
mailing lists members are working on.

A GTK+ Swing look and feel would make embedding of Swing apps into GNOME
(and vice-versa) considerably more attractive however.

Erdi Gergo (ca...@ru...) had a project called 'monkeybeans' some
time ago that was an attempt to provide a bonobo implementation for
Java.  I think he got frustrated with it; but we (GNOME accessibility
folks) needed to do this as part of our work, too.  So we discovered
some of the reasons why monkeybeans was blocked (I think) and now we
have GNOME's Bonobo::Unknown and bits of the other base libbonobo IDL
implemented in Java, along with all of the GNOME Accessibility IDL in
'at-spi'.  (Unfortunately the CORBA support in versions of Java before
1.4 was pretty broken, it's not too surprising that Erdi was having
problems.  Also there were misunderstandings about how the "POA"
worked...)

Erdi has blessed the idea of calling the new work "monkeybeans2".  At
present the code lives in GNOME CVS's "java-access-bridge" for
historical reasons, but we have agreed that Java/Bonobo implementation
code and bindings are of general interest and the Bonobo:: parts of
java-access-bridge should be split out into a new "monkeybeans2"
module.  So far I haven't had time, but it's not a big job to do this
bit of surgery and it makes a lot of sense, since other GNOME CVS
modules are also using this work.  For instance 'gnome-speech' which
provides text-to-speech services; one of the available drivers (for the
FreeTTS service) is implemented in Java and thus uses java-bonobo.

At the moment we've mostly just implemented Unknown and some of the
basic PropertyBag APIs from Bonobo, but most of libbonobo will soon be
required, and libbonoboui (the GUI embedding and control stuff) would
make sense to do.  Having this would make embedding, control, and the
ability to write GNOME components in Java (and vice-versa) possible.

If someone on this list is interested in this type of java/GNOME
integration, and would like to help split the existing work into the new
CVS module (monkeybeans2), or even help maintain it, I would be
grateful.

Bill Haneman

Re: [Java-gnome-developer] Gnome2 for Solaris DE

[Tom B. <Tom...@Su...>]

The only related work is a Swing L&F which *simulates* GTK by reading
the theme info and using the referenced graphics files.  Perhaps a demo
of that work got the writer excited, so that he jumped to an unwarranted
conclusion.

Although it's possible some random engineer is working on a GTK AWT
toolkit (Sun's a big place), neither the Mad Hatter or JavaSoft teams
are, and they are where such a project would get released.

No problem. We'll help wherever possible & I'm sure other readers of
this list are glad to hear such advice.

Look at src/example/gtk/tree/TreeExample. 

You can add multiple renderers to each column (as is done in the first
column of the example). If the first one you add is a
CellRendererPixbuf, then you should get your desired effect. 

You will have to (for now) store the names of the image to be displayed
at each node in one of the data blocks of the treestore and map this to
the renderer in the column using something like
myTreeColumn.addAttributeMapping( myPixbufRenderer,
CellRendererPixBuf.Attibute.PIXBUF, 1)
