[Java-gnome-developer] GUI Building Differences

Hi,
This might seem like a dumb question, but I thought it would clarify
things for me :)

I use Eclipse for the development of course, and I use the nice plugin
that's available. Now, this plugin can create either a gnome-app or a
glade-app.
Now I've not much experience with gnome development at all, but I have
been poking about in glade. So with glade, you can create a gnome
project, or a gtk project. Is this related to the differences in java-gnome?
I thought it was excellent to be able to build interfaces with glade.
However it appears as though (based on the documentation on java-gnome
web site) that using glade is not the main method - or even that using
glade will not tie in with development based on java-gnome.

I guess I'm asking if there are really two distinct and separate
approaches - plain gtk using glade for example, and gnome that has to be
coded completely by hand?

One of the things that I thought was great (and missing from java dev
land) is a good gui builder, and glade provides that, lets you define
your signals etc. But I get a feeling that java-gnome is down a
different path than what is provided by libglade??

Thanks.

Asking never hurts. ;)

Gnome extends GTK in several ways, the main one regarding your question =20
being libgnomeui, where you get some more widgets. Glade and Java-Gnome =20
both offer you:
- to use strictly and only GTK+ (some people don't like gnome-=20
dependencies for their application) or
- to use the full spectrum of the gnome-libs. For Glade you'll notice =20
the extra set of widgets you can use then, especially the GnomeApp, =20
which should be the base widget of any Gnome-Application.

Above I've talked about GTK+-only vs. Gnome, your next question has =20
nothing to do with that. For "programming" an app, you have the choice =20
to code the GUI by hand or to use glade, for both, gtk and gnome.
Java-Gnome uses GladeXML, which is quite language-independent, so it =20
basicly ties to java-gnome as well as to C or C++.
Code generation is not supported, but that's ugly anyways. ;)

So no, it's using libglade appropriately. Although I don't think auto-=20
connecting signals is possible, it's quite C(++)-specific, but I might =20
be wrong here.

Hope that helps a little, bye,
