How to use a Glade UI (.glade file) in a Java Gnome/GTK program?

[Igor H. Vieira]

I've did a research on the Internet looking for tutorials/documentations to
explain me how to use a UI designed in Glade in a Java Gnome project, but
no luck. I already know how to create a UI from the code using the Java
Gnome/GTK. Anyway, I'd like to use a Glade UI that I've created in a Java
Gnome/Gtk project, but I have no idea from where to start. Please tell me:

- which packages I need to install;

- how to integrate the UI I've create with Glade (the .glade file) with my
Java Gnome/Gtk project (specifically in Eclipse);

- and give an example.

Thanks in advance.


That's how my Glade UI looks (Just click the image to see it bigger):

This is the XML code of the UI above:

<?xml version="1.0" encoding="UTF-8"?>
<interface>
<!-- interface-requires gtk+ 3.0 -->
<object class="GtkWindow" id="window1">

In the java-gnome source tree there is an example at
tests/prototype/Designer.java ; you might have a look at that and give
it a try?

You're probably better off just doing that, then. To be honest, that's
what we tend to recommend; Glade always seems like such a great idea,
but pretty soon you end up needing to write code to do non-trivial work
anyway, at which point the complexity of dealing with .ui files & code
is greater than just having code.

Speaking personally,

button = new Button();
button.setLabel("Hello");

and

button = (Button) builder.getObject("button42")
button.setLabel("Hello");

amounts to much the same thing while the latter is definitely more
fragile in the face of change. IMHO, anyway.
