Glade and Java

[covert215]

I am using Glade to design the GUI for a program I am working on. I have installed libgconf-java, libglade-java, libgnome-java and libgtk-java. However, Glade does not give me the option of building in Java. What could I be doing wrong?

Use the Glade class (http://java-gnome.sourceforge.net/4.0/doc/api/org/gnome/glade/Glade.html) to go directly from a Glade XML definition to a running Java GUI.

No need to do code generation via Glade. You just load the Glade XML at runtime from the filesystem.

Make sure the Java GTK bindings are on the CLASSPATH of your Java project.

The binding should be in a JAR file with GTK in the filename in the directory /usr/share/java.
