Glade and org.gnome.gtk.Builder

I have wrote a medium sized app with the bindings and they work well.
But I have not been able to get org.gnome.gtk.Builder working with even the
simplest example.
Should I be using a certain version of Glade?

Using Ubuntu 12.04

OpenJDK 7 and Sun Java6

Glade 3.8 and 3.12

OK, got it to work but I had to define the object types to use first or it
would not parse the file.

Example simple window with one button

w = window
b = button

So, that means I have to know what is in the builder/glade file before
hand?

Hm, I thought I'd sent a reply to your first message, though all I was
going to say is "can you show us the code that isn't working?"

Um, no, you shouldn't; just getting a reference to the top level Window
object should be more than enough.

You did call w.showAll(); right?

I am making it work doing some funny stuff on Ubuntu 12.04 with 4.1.2 from
the java-gnome ppa.

I can not get Designer.java to work with simple.ui sample.

http://research.operationaldynamics.com/bzr/java-gnome/mainline/tests/prototype/Designer.java

***@Michelle:~/TESTING$ javac Designer.java
***@Michelle:~/TESTING$ java Designer
Exception in thread "main" java.text.ParseException: Invalid object type
`GtkLabel'
at org.gnome.gtk.Builder.addFromFile(Builder.java:107)
at Designer.setupUserInterface(Designer.java:46)
at Designer.main(Designer.java:80)
***@Michelle:~/TESTING$

I can then pre-define Label() or whatever widget before calling builder and
it works.

And in my case, I have done some glade files with hundreds of widgets.
As long as define say one widget type of say a Spinbutton then it will
load the other 50 spinbuttons fine.

Thanks, so far other than that they are some really nice bindings and I
definitely want to see them stay around.

Ah, damn. Not your fault. There is an engineering problem and
unfortunately the person working on it has been busy with other work the
past year.
Have a read of
http://article.gmane.org/gmane.comp.gnome.bindings.java.devel/1606
For the mean time, the workaround of forcing instantiation of the
[native] class is indeed going to work. I'll see if we can get our heads
together to get a more proper fix. Clearly this sucks; I'll start a
thread on java-gnome-hackers.

Hi!

I had worked on that a long time ago. However, I've been really busy the last year, so I had no time to finish it.
I case any of you is interested on this, I have pushed the last code I had to:

http://research.operationaldynamics.com/bzr/java-gnome/hackers/vreixo/gtkbuilder/

The approach is rather different to both Gtk+ and the old java-gnome way of handling glade-based UI.
My approach makes use of java annotations, which provides an elegant and highly productive way of dealing with the loading of glade-based files.
It is based on an old (and great!) code submitted by Franco Bulgarelli.

I remember to have written some examples/demos, so I hope that would be enough for you to understand
how this works.
In any case, I think I have not finished the support for thing like handlers. In fact, my local branch has several uncommitted

changes related with handler support.
Unfortunately, my last commit is almost a year ago, and I don't really remember what my code was or what parts were missing.
I would need to spend some time on it, but I am writing my PhD thesis right now and I have no time for this, I'm really sorry.
I just remember most of the work was already done. I will try to finish this as long as I have time, but that won't be at least until November.
Please remember me my commitment if you don't hear anything from me by then.

In any case, if any of you wants to continue my work, be free to contact me. I be willing to send you the uncommitted changes I have and help you as most as I can.

Best regards
Vreixo
