Re: [Java-gnome-developer] glade event problem and glade java examples wanted

[Clint A. <ca...@au...>]

Here's a little program I use to test out my Glade GUIs.  You could easily
subclass it and have it handle events for a specific widget.

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

I don't know about the errors (just started using java-gnome..) but I just
created an example how to 'communicate' between java and glade. Because it's
verry simple but it took me a long time to find out how..

Its here: egzz.net/java-glade.html
If you (the website maintainers) like it, I can convert it to wiki and add
it to the java-gnome site?

[Java-gnome-developer] glade event problem and glade java examples wanted

[Michael S. <mic...@gm...>]

hi

i installed java-gnome today and wanted to try it out with glade. i compiled
and ran the HelloWorldGlade example from:

http://java-gnome.sourceforge.net/cgi-bin/bin/view/Main/JavaGnomeHelloWorld#HelloWorldGlade

The gui shows but the events don't work (clicking on the button does not do
anything, and closing the window does not terminate the application either).
when i launch the application the following message appears on the command
line twice (i suppose once for the button event and once for the window
event):

java.lang.reflect.InvocationTargetException: ListenerDelegate.create failure

does anyone have any idea to why this happens and how to fix it?
and does anyone know of a / have a bigger / better example of how to use
glade with java-gome (on how to access widget properties and to handle
events)?

also the the jgo.sh script on the the java-gnome.sf.net website should
probably mention that its last line:

${JAVA} -classpath
${JG_JARS}gtk2.4.jar:${JG_JARS}gnome2.8.jar:${JG_JARS}glade2.4.jar:${JG_JARS}gconf2.8.jar:${CLASSPATH}
$@

might need modifications regarding the version numbers of jar files. it took
me hours to figure out why my java-gnome installation didn't work. maybe on
of the website maintainers reads this email and can mention that.

thanks

Re: [Java-gnome-developer] Word wrap in a CellRenderText

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

Hmmmm

Here's a quick hack: if you put <br> tags, it'll break lines... but of course it won't be as
dynamic as you want :P

So... the *real* solution to your problem, i believe, would be this: write a custom cell renderer.
Now that's the challenge: how hard is it to write a custom cell renderer with JG? Maybe JG should
provide some base class for custom cell renderers (*hint hint*).

Here's a C tutorial on how to write custom cell renderers:

[Java-gnome-developer] Word wrap in a CellRenderText

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

Hey there,

I'm in the process of using a simple single-column ListStore backed
TreeView to display a summarized version of some data, and I'm having a
little trouble fine tuning the rendering - I need word wrap.

As some of you know, I'm working on something which, broadly stated,
involves displaying XML data. This particular window is a high level
summary, which simplifies navigation around the more specific details of
the document in other windows. As such, I've just read in selected XML
nodes, and composed a single string - with Pango markup - for display in
the TreeView widget.

Pango obviously provides for wrapping text in Labels; and likewise
TreeView (care of TreeViewColumn and CellRendererText.Attribute.MARKUP)
provides for displaying text with pango markup, so text of 

                This is <big>some huge</big> text, and <span
                size=small>this is small</span>

works. The trouble is that there's no markup code (that I can find) for
word wrap.

I looked up the GNOME manual, and Labels definitely have a wrap
property, and java-gnome lets you at it with Label.setLineWrap(true).
However, the text cells in a TreeView are not Labels, even though the
same pango engine is used to render them.

CellRendererText has a method called setAttributes(AttrList attr). That
seems to be the way to Pango, but when I look at the org.gnu.pango
classes, I can't figure out how to create the Attribute objects which it
uses.

Within org.gnu.pango there's a Layout class, which has
setWrapStyle(WrapMode.WORD), but I can't figure out how to get to
Attribute from Layout, or vice versa - for that matter, I can't figure
out what generates Layout objects.

So obviously I'm way off in left field here. If <span wrap="true">
worked, then this would be easy, but that doesn't work (and, in fact,
throws quite the error :)).

If I wasn't using a TreeView, then it would just be labels and would be
easy - but if I was forced to do that then it would mean trying to
manually duplicate the effect of the TreeView widget, and that's going
to be near impossible.

Help? :)

A small screenshot of what I'm fighting against is attached. The lines
in italics are all much longer, and the ones that need to be wrapped
instead of cut off.

Re: [Java-gnome-developer] GTKExtra

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

Having never heard of GTKExtra, I did a quick search:
http://gtkextra.sourceforge.net/

This project seems to be abandoned since 4 years ago and implementes widgets
which are already part of gtk+.
In terms of binding for java, you'd probably have to work on a full set of
gtk1.2 bindings first... It's not worth it.

[Java-gnome-developer] How to use the Canvas

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

I've been trying to use the Canvas lately, but with no success... i've tried to add a CanvasText
to a Canvas, but its just not appearing. Is there a problem with the Canvas? Is there an example
of how to use it? I've tried doing:

------
Canvas canvas = (Canvas) glade.getWidget("canvas1");
CanvasText text = new CanvasText(canvas.getRoot());
text.setData("text", "testing...");
canvas.showAll();
------

Thanks,

[Java-gnome-developer] Specific GTK macro

[Noup <lu...@ma...>]

Hello everyone.
I'm currently intending on writing an application using the java-gnome 
API. I've never used this API before, and so i have a doubt that 
strongly constraints whether i will or not be able to use this 
collection of bindings instead of gtk itself: is there any 
correspondence to the GDK_WINDOW_XWINDOW macro (see 
http://www-eleves-isia.cma.fr/documentation/GtkDoc/gdk/gdk-x-window-system-interaction.html#GDK-WINDOW-XWINDOW-CAPS)?


Thanks in advance,

[Java-gnome-developer] Backport of libgnome 2.8 - please test!

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

I've made a backport of libgnome-2.8.2 to run on Gnome 2.6. Basically what i did was to remove all
2.8-specific calls (which strangenly weren't many: just 2), and compile it on Gnome 2.6.

It compiled fine, and i ran a gnome HelloWorld just fine. But, we can't make this official because
we don't know exactly how good this backport is, if there's some problem, etc.

*So*, here's what i'm doing: i'm making the backport avaliable to allow people to test it. I've
packaged it with autopackage, you may download it here:

http://www.angelfire.com/linux/jvic/libgnome-java-2.8.2.x86.package

To install:
 * Download (you may have to 'right click->Save link...')
 * Make it executable
 * Double-click it, it will install it.

To see the files installed:
 $ package files libgnome-java

I have also made a patch avaliable, for the ones who want to build it, or to see what were the
changes. Here's the patch:
http://www.angelfire.com/linux/jvic/libgnomebackport.patch

That's basically that; please test and send feedback.

Oh, if you're wondering why i've backported it: i believe there's still many people on Gnome 2.6,
and i'd like to make Java-Gnome avaliable for this people too. Mdk, for example, is still on Gnome
2.6 and will be till July probably. And even when it releases a new version, many ppl won't
upgrade immediately. There's also a lot of ppl still using Fedora 2. So, that was the reason,
basically.

Cheers!
J.V.

I'm not sure, but you might try moving the Program.init call before the
try/catch block (i.e. before calling "new LibGlade").

My first instinct would be to say "does the identical thing happen if
you're using Sun Java JDK 1.4?" Maybe you could try that...

[I don't think too many of us are using 1.5 yet. Certainly we're not
using its language features as there is an active subgroup of us who are
using kaffe or GCJ and thus more or less limited to Java 1.2 APIs]

My second instinct would be "did you build java-gnome with this Java 1.5
JDK?"

[Java-gnome-developer] jvm crash JDK 1.5

[Rafael F. <ra...@op...>]

Hey can anyone tell me why I keep getting JVM crashes with the 1.5 JDK
and some org.gnu.gnome widgets, like About? 

For instance, I'm trying to call this:

About about = new About("Jyum","0.1","GPL","The Java yum
interface",documenters, documenters , null ,null);
about.show();

and I get a very nasty jvm crash (attached)... however, gij seems to not
have any problems.

[Java-gnome-developer] Getting started with jhbuild

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

I am frequently asked questions on irc or this list about
building a gnome environment using jhbuild.  This is
necessary if you wish to use the java-gnome cvs HEAD
as we track the gnome cvs HEAD.  What follows is an
explanation of the way I use jhbuild to maintain an
environment for java-gnome dev elopment.

Jhbuild is a tool that will grab libraries and applications
either from cvs or released soruce tars and build them
in the correct order based upon their dependencies.
What is built is driven by a file named .jhbuildrc located
in your home directory (I'll call it the config file here). 
I have attached my current file here so you can see 
my settings.  I will talk about a few of the settings in 
the next paragraphs.

The first and most important setting in the config
file is the moduleset.  This tells jhbuild what version
of each modules to build.  Currently I am using 
'gnome-2.10' since I want the development version
of the modules.

The next setting to discuss is 'modules'.  In the 
gnome world there is a new release every six months.  
As you might expect, the environment is much more 
stable later in that six month cycle than it is early in 
the cycle.  I switch my 'modules' setting about 3 months
into the cycle.  During the first three months I use
['meta-gnome-devel-platform', 'meta-gnome-devel-tools'].
Sometimes I remove the devel-tools if they seem to be
unstable.  This provides all of the core libraries that
I need to develop java-gnome.  The last three months
of the cycle I change my 'modules' setting to
['meta-gnome-desktop'].   This builds the entire desktop
and many related applications.  During the last two
months I sometimes even use this desktop.

'skip' is a very nice feature.  I almost always skip
mozilla since it takes so long to compile.  I also include
'evolution' and other applications that take a while to
compile'

'prefix' tells jhbuild where to install the newly built gnome.
'checkoutroot' tells jhbuild where to checkout and build
the applications.  I create a directory in my home directory
called gnome and a directory called cvs under gnome.  I
use these directories for prefix and checkoutroot.

'autogenargs' tells jhbuild what parameters to pass to
autogen as it builds the modules.  If you want to pass
specific parameters to one package you can use
'module_autogenargs'.  

When the compilation or installation of a module fails
there are a couple of things you can do.  Quite often
you can tell jhbuild to 'go to stage force_checkout' and
it will build correctly.  Another problem I have seen is 
when there is a conflict with a .cvsignore file.  In these
cases I usually drop to a shell and delete all of the contents
of the directory including the .cvsignore file.  When I
exit the shell and jhbuild starts again it checks out the 
files and continues with the build.  If all else fails you
can google.  There are many developers that use jhbuild
and they might have already discovered and fixed
the issue you are seeing.

Since you are going against cvs there will be some times
when the code will not compile.  Look at the module and
perhaps you can just skip it.   Sometimes you cannot complete
the process and must stop jhbuild.  The majority of the time
it will complete successfully.
