Re: [Java-gnome-developer] how to specify classpath

[Andrew C. <an...@op...>]

I assume you had a look at the README file that comes with java-gnome.
It has further examples of running code:
http://java-gnome.sourceforge.net/4.0/README.html#using
but the problem you're having is fairly simple to address.

Although Java searches paths for hierarchies of .class files, it does
not load .jar files. You have to specify them by name. 

$ cd doc/examples/
$ javac -classpath /usr/share/java/gtk-4.0.jar button/ExamplePressMe.java

And to run it,

$ java -client -ea -classpath /usr/share/java/gtk-4.0.jar:. button.ExamplePressMe

[You may need to add -Djava.library.path=/usr/lib/jni on Debian; I'm
not sure if that's on the default system linker search path]

Yes, this is all a bit verbose, but unfortunately that's the way Java
is.

++

Or you could do it all from another location:

$ javac -classpath /usr/share/java/gtk-4.0.jar -d /tmp/examples /path/to/java-gnome/doc/examples/button/ExamplePressMe.java
$ java -client -ea -classpath /usr/share/java/gtk-4.0.jar:/tmp/examples -Djava.library.path=/usr/lib/jni button.ExamplePressMe

Hopefully you see the pattern now.

++

If you were build java-gnome from source yourself, you would find that
`make test` also builds the example code (and puts the resulting .class
files in tmp/tests/). so,

$ java -client -ea -classpath tmp/gtk-4.0.jar:tmp/tests/ -Djava.library.path=tmp button.ExamplePressMe

would run it for you.

Good luck,

[Java-gnome-developer] how to specify classpath

[한. <yut...@gm...>]

I use Sun java from debian.

// example.java
import javax.swing.JTextField;

public void .... {
.. blah.. blah..
}
//end of example.java

as you know(s) `javac example.java` works.
because probably javax packages were registered by sun java, some
where as global settings (classpath).

To compile 'ExamplePressMe.java'; downloaded from
'http://java-gnome.sourceforge.net/4.0/doc/examples/button/ExamplePressMe.html';
'javac ExamplePressMe.java' shows error that It can't find where they are.

My error :
$ javac ExamplePressMe.java -classpath /usr/share/java
ExamplePressMe.java:13: package org.gnome.gdk does not exist
import org.gnome.gdk.Event;

Debian :

Would you tell me how I can make javac recognize these classpath, plz?

[Java-gnome-developer] missing cairo bits?

Hi. From what i can tell, the Cairo bindings - despite having a lot of

[Java-gnome-developer] java-gnome 4.0.7 released

[Andrew C. <an...@op...>]

I am pleased to announce a new release of the java-gnome user interface
library.

Tarballs of 4.0.7 can be downloaded from:
http://ftp.gnome.org/pub/GNOME/sources/java-gnome/4.0/ 

Release notes are, as usual, in the NEWS file:
http://java-gnome.sourceforge.net/4.0/NEWS.html#4.0.7

++

Serkan Kaba was mentioned as one of the people to whom credit is due;
Serkan is a long time participant in #java-gnome who took the time to
test building the 4.0.7-rc1 release candidate. Doing so he uncovered a
problem whereby String's toUpperCase() was behaving unexpectedly and
breaking the build as a result. Turned out to be a side effect of the
Turkish locale and that while Character.toUpperCase() is deterministic
in the face of changing locales, String.toUpperCase() is not. Serkan,
having seen this sort of problem with other (otherwise mature) Java
projects, was able not only to help pin down the cause but also
contributed the fix as well.

I mention this because this is the sort of bug that is bigger than any
one person or organization. They lurk in every project. It serves as an
nice reminder of the outstanding quality of Open Source as a software
development process. Thanks Serkan!

That's a reasonable thing to want to do. You need something that isn't

[Java-gnome-developer] 4.0.7-rc1 up

[Andrew C. <an...@op...>]

I've done a release candidate for java-gnome 4.0.7

As described before, there's nothing requiring us to do RCs; but they
have proved useful. This time around, there are two audiences:

One, people doing packaging can check and make sure that 4.0.7 is all
sorted for them. Remember that the goal is that *zero* configuration and
build related patches be necessary; after all, we want people to be able
to build & hack on java-gnome itself if building it themselves from
source and if a distro's packages have a huge patch set then we aren't
doing our job to support them.

Second, people with serious apps wishing to use 4.0.7 as the release
they depend on for their own next release can check that stuff they
_really_ need is in there.

I have delayed the release of 4.0.7 until 27 April or so. I are moving,
and so I will be off the direct internet for the next week (at least, I
hope it's not any longer than that. {sigh}, telcos. I will be able to
get email intermittently; if you want to chat, use the mailing lists.

Cheers,

You should be able to just do:

In most cases, that stuff documents the design process we used to get to
the architecture we have now; and so most some of it speaks from the
point of view that things stood two years ago before we had done all the
work.

I have been planning to redo that from its current historical role to
present-tense architecture documentation, but that can wait.

Also if you don't want to use the Sun JDK; on a Debian/Ubuntu system you 
could install the "java-gcj-compat-dev" package 
(http://packages.debian.org/etch/java-gcj-compat-dev) and use the

$ ./configure jdk=/usr/lib/jvm/java-gcj

The root cause problem is that GCC has a jni.h file that isn't
compatible with other things, like, say, Java. We've been battling this
for a long time now. Two things:

1) don't let your distro fool you into thinking that GCJ is a JDK. It's
many wonderful things, but a compliant JDK it is not. That, and it's a
dead project. So don't use it anymore.

2) Try 

        $ ./configure
        jdk=/path/to/whatever/the/java/home/is/on/your/system

Based on the work that Manu has been doing to build proper Debian
packages, you might find that

        $ ./configure jdk=/usr/lib/jvm/java-1.6.0-sun

could work for you.

If that doesn't work, can you send along the output of .config{,.tmp}?
Also, if you hang in #java-gnome we can probably solve this
interactively. Thanks.

You're asking about TreeStore. Given the work in place for TreeModel and
ListStore, along with the infrastructure behind them, it should be quite
achievable for someone new to contribute the necessary coverage.

The part that makes TreeStore different is that it has methods to insert
a new row as a child of an existing row, or above it, along with methods
to manipulate an existing hierarchy. That's what will need a bit of
attention as compare to ListStore.

If you're interested in doing the work on this one, give me a shout on
#java-gnome once you've read into the guts of our TreeModel bindings and
the Overrides that go with it. You'll also want to get up front and
personal with the GTK API documentation for GtkTreeStore and friends.

Thank you for answer. It works. And what about image and text in the

Yes. You [can] pack (one or more) CellRenderers into ComboBoxes the same
way you pack (one or more of) them into a TreeViewColumn.

Well, I have no idea what JLabel does or doesn't do, but in GTK you use
Pango markup to add emphasis to what would otherwise be ordinary text in
a Label or a CellRendererText. See
http://library.gnome.org/devel/pango/stable/PangoMarkupFormat.html or
http://www.pygtk.org/pygtk2reference/pango-markup-language.html

and use

Can I display combobox with images in the cell? Or html text (like
JLable)? Or text and icon inside one cell (like JLable, too)?

Also I wonder, is there any way to create a "lazy" table (or tree)
model, which provide data only as they displayed (not all data at once)?
