[Java-gnome-developer] win32 patches, build howto and tarballs

[Robert S. <rob...@gm...>]

Hi,

patches for building the basic java-gnome packages on win32 are
attached to bug #339270 [1]. The changes are minimally invasive, just
some *nix-isms that have crept in since the last porting effort. A
brief step by step build howto is included as well.

[2] has fresh builds which have been verified to work for simple test
apps. These have been done using mingw (unlike some cygwin attempts
discussed recently on this list).

If anyone interested could try the patches or builds and provide
feedback that'd be great. Andrew agreed to accept the stuff once it
has been confirmed working by a broader audience.

[Java-gnome-developer] Localization tutorial and gDVB release plans

[pancake <pa...@ph...>]

This morning I wrote a new tutorial for JavaGnome explaining how to localize
Java-Gnome applications. This is done by using the i18n API from the Classpath,
giving some tips for proper coding to skip translation problems.

I've also fixed some other pages in the wiki to use the
%CODE{"java"}% // %ENDCODE%

[gdvb]

I'm planning the release of gdvb 0.4 for this week, with dvb-t, dvb-c
support, lot of fixtures and code cleanup, with spanish/catalan/german/english
translations, channel filtering support and more ...

For the impatients:

[Java-gnome-developer] 2.8 binaries for windows?

[Manuel C. <ll...@us...>]

Hi all,

The binaries for windows at:

http://java-gnome.sourceforge.net/cgi-bin/bin/view/Main/GetJavaGnome#Binary_for_windows

are for version 2.6. The 2.6 release contains the bug where you can't
save Objects to TreeModel Columns, different constructor for Window, ...

Has anyone a 2.8 binary package?

Thanks!

On my system, libcairojni.so links against libfontconfig.so.1, so I
would assume the answer would seem to be yes.

[Java-gnome-developer] cairo-java dependency on fontconfig

[Emmanuel R. <emm...@gm...>]

Hi,

I noticed that the package cairo-java depends on fontconfig but I don't 
think that fontconfig is directly used by the bindings.
The include directives of the JNI files have no reference to fontconfig.

I know that cairo uses fontconfig but I don't think that cairo-java has 
to depend on fontconfig.

Is fontconfig really necessary?

So I ran into something similar when trying to profile one of our
applications with JMP, http://www.khelekore.org/jmp/ 

I *did* call Gtk.init(). Then, same as you, right as the first thing
that constructs a Window [in this case from LibGlade] but well before I
get to Gtk.main(), this spits out:

        Xlib: unexpected async reply (sequence 0x1435)!

and the Java program hangs. A few minutes later this spits out:

        (jmp:3790): Gdk-CRITICAL **: gdk_drawable_get_screen: assertion
        `GDK_IS_DRAWABLE (drawable)' failed

No surprise there - thing is hung.

I've seen the dreaded unexpected async thing before, usually when I've
done something stupid, though stupidly I can't remember what that might
have been.

I suspect that we're doing something wrong in java-gnome, somewhere deep
down. But I can't begin to think what.

AfC

P.S. In case you're curious, one runs JMP via a -Xrun argument to your
VM; command line I used is:

        $ java \
                -Xrunjmp:jvmhold \
                -classpath /opt/local/java-gnome/share/java/glade2.12.jar:/opt/local/java-gnome/share/java/gtk2.8.jar:/opt/local/java-gnome/share/java/glib0.2.jar:tmp/classes \

Problems such as this are long since fixed in newer versions of
java-gnome. Please try again with libgtk-java 2.8.5, which is part of
the latest release:

[Java-gnome-developer] Integrating Java-GNOME into Eclipse

[Remy S. <rem...@gm...>]

Hi,

I was wondering if anyone had any experience with using the bindings from
within an Eclipse instance. Say something like clicking an IAction which in
turn runs the code below...

w =3D new Window();
w.showAll();

or something like that. The VM crashes on me instantaneously when
instantiating any Eclipse UI functions after the fact (such as opening up
the preferences window). It might also occur before the fact, but I forgot
to test that (and I am not in a position of testing that theory right now).
I also forgot to test whether this happens with just a standalone SWT
application or not, but the way that SWT is talking to GTK+ is most likely
the reason why this clash is occurring. I did not call Gtk.init(null) since
I figured SWT would've called it already. I also didn't call Gtk.main()
since it just blocked the SWT thread and prevented Eclipse from starting at
all (the startup progress bar just hanged).

So if anyone has a code snippet or know of a way for Java-GNOME to work wit=
h
SWT/Eclipse, please let me know!

Thanks,
Rem

A bugzilla user by the name of "Cygwin Ports Maintainer" (Yaakov
Selkowitz, I think) sent us some patches a while back; I would assume he
got at least something to build as a result of them. See
http://bugzilla.gnome.org/show_bug.cgi?id=324665
perhaps these changes need to be applied to the other libraries as well?

A bug that seems like it's been open forever is
http://bugzilla.gnome.org/show_bug.cgi?id=155115 ; perhaps it would give
you some insight.

Good luck!

[While we (my firm) don't have any interest in targetting Windows
ourselves (we write Java for Linux, not Java for cross platforms), I
certainly have nothing against the idea of java-gnome being able to be
used on win32. Open source is about choice, after all. You get to choose
to use Windows, I get to choose not to. Of course, you have to get it to
work first :) but I will happily apply patches that make it do so]

Hi,

I got inspired by Gustavo Hexsel's mail and I also tried to compile the 
Java-GNOME bindings for Windows XP.

I assumed that the way to do it was to install cygwin in order to have 
make, gcj, gcc and g++ and then to install the GTK Win32 binaries from 
the gladewin32 site (http://gladewin32.sf.net).

So far I managed to build cairo-java, glib-java and libgtk-java, but I 
got into some serious problems when I tried to run a simple example that 
uses the gtk libraries. At first, java (Sun's JDK 1.5) kept complaining 
that the Java-GNOME DLLs where missing. I noticed that cygwin created a 
bunch of files with the extension '.dll.a' so I removed the '.a' from 
all the files in order to have the '.dll' extension and now I get a 
windows popup with the following error:

"The application or DLL 
C:\cygwin\home\hpadmin\eclipse-bin\libgtkjni-2.8.dll is not a valid 
Windows image. Please check this against you installation diskette."

I'm starting to think that using cygwin is not the way to go.

Any advice?

We had some terrible glitches with Color about 15 months ago. Does
anyone remember if we sorted that out or if there are outstanding
concerns?

[I recall that I had a horrid time when I expected Color to react to hex
values representing values in the 0-255 range. GDK's Color, however,

Interesting is that on the KDE machine and on the Gnome machine the versions
of all packets are the same (debian with dist-upgrade on both).
The problem doesn't appear if the colors are made not by string , but by 
int values for the RGB. Maybe this is some bug in gnome libraries

Just a thought: This may be an excellent time to cut the branch for

Hi there java-gnome people!

We're going to be cutting releases to comprise java-gnome 2.13.4 this
weekend. Bug fixes all round - just about every library has been touched
in some way or other.

Some of you have open bugs that you've kindly reported on Bugzilla.
We're getting better at using it as a tool, but we're still not perfect
[nor will we be; this is, after all a volunteer project]... so if you
have an issue which has been holding you up or some problem you ran into
that you want to see fixed, we REALLY need you to:

* Find your bug and tell us if it is still a current problem by adding a
comment. Many issues were reported up to a year ago, and libgtk-java
especially has made huge strides in stability and completeness since
then.

* If you ARE still having the problem, then if you can duplicate it with
current CVS and comment the bug accordingly. [If you need help with
that, talk to us on #java-gnome on gimpnet]

* If the bug isn't current anymore, then please do close it.

Talk to you soon!
