[Java-gnome-developer] Problem running glade program

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

Hi,

I'm trying to run this java/glade program but it doesn't work
http://java-gnome.sourceforge.net/cgi-bin/bin/view/Main/GladeGUIS

Where can I find documentation for java/glade/gtk?
In the documentation page are a lot of dead links:
http://java-gnome.sourceforge.net/cgi-bin/bin/view/Main/HintsAndTips
so this isn't useful..

Here's what I tried:

copied the glade file and java file and putted them in the files
SimpleGladeExample.java and example1.glade and removed the // lines

then compile (javac SimpleGladeExample.java or gcj --main=SimpleGladeExample
SimpleGladeExample.java)

The errors are:
SimpleGladeExample.java:19: cannot resolve symbol
symbol  : variable glade
location: class SimpleGladeExample
glade = new LibGlade(inputStream, this, gladeRoot);
^
SimpleGladeExample.java:33: non-static variable PROGRAM_NAME cannot be
referenced from a static context
Program.initGnomeUI(PROGRAM_NAME, PROGRAM_VERSION, args);
^
SimpleGladeExample.java:33: non-static variable PROGRAM_VERSION cannot be
referenced from a static context
Program.initGnomeUI(PROGRAM_NAME, PROGRAM_VERSION, args);
^
SimpleGladeExample.java:35: cannot resolve symbol
symbol  : variable Gtk
location: class SimpleGladeExample
Gtk.main();
^
4 errors

So in the code:
import java.io.*;
import org.gnu.glade.*;
import org.gnu.gnome.*;

public class SimpleGladeExample {

private final String PROGRAM_NAME = "Glade Example";
private final String PROGRAM_VERSION = "1.0";

private final String gladeFile = "example1.glade";

private final String gladeRoot = "glade_root_element";

private LibGlade libGlade;

public SimpleGladeExample() {
try {
InputStream inputStream = getClass().getResourceAsStream(gladeFile);
glade = new LibGlade(inputStream, this, gladeRoot);
} catch (GladeXMLException e) {
e.printStackTrace();
System.exit(-1);
} catch (FileNotFoundException e) {
e.printStackTrace();
System.exit(-1);
} catch (IOException e) {
e.printStackTrace();
System.exit(-1);
}
}

public static final void main(String[] args) {
Program.initGnomeUI(PROGRAM_NAME, PROGRAM_VERSION, args);
SimpleGladeExample example = new SimpleGladeExample();
Gtk.main();
}
}
I changed
private LibGlade libGlade;
to
private LibGlade glade; .....

But then when I compile tihs are the errors:
SimpleGladeExample.java:33: non-static variable PROGRAM_NAME cannot be
referenced from a static context
Program.initGnomeUI(PROGRAM_NAME, PROGRAM_VERSION, args);
^
SimpleGladeExample.java:33: non-static variable PROGRAM_VERSION cannot be
referenced from a static context
Program.initGnomeUI(PROGRAM_NAME, PROGRAM_VERSION, args);
^
SimpleGladeExample.java:35: cannot resolve symbol
symbol  : variable Gtk
location: class SimpleGladeExample
Gtk.main();
^
3 errors

Thanks for your help in advance,
David

Hi,

I understand that you are doing this in your free time and I appreciate
this. Sorry if my mail looked like a flame.

I changed the file and compiling now works! but now I get an error when I
run it:

$ java SimpleGladeExample

(java-gnome:7634): GConf-CRITICAL **: file gconf-client.c: line 547
(gconf_client_add_dir): assertion `gconf_valid_key (dirname, NULL)' failed
org.gnu.glade.GladeXMLException: <property> element should be empty.  Found
<b>.
at org.gnu.glade.LibGlade.glade_xml_new_from_buffer(Native Method)
at org.gnu.glade.LibGlade.<init>(LibGlade.java:123)
at SimpleGladeExample.<init>(SimpleGladeExample.java:20)
at SimpleGladeExample.main(SimpleGladeExample.java:35)

I don't have gnome installed (I use xfce), could this be the reason? I don't
need gnome for glade, do I?

Thanks,
David

David,

I was the one who put up the little Glade example. I know that it is far
from finished but I realized that there were no other useful examples
anywhere.... well: that's why I thought: better my more or less useless
stuff than nothing.... :-)

There are some good tutorials on how to actually RUN java-gnome
programs. For the simple example I've put online you need the gnome
libraries!

You can start the example like this:
  JNI=3D/usr/lib/jni
  CP=3D/usr/share/java
  CLASSPATH=3D$CLASSPATH:$CP/gnome2.8.jar:$CP/gtk2.4.jar:$CP/glade2.4.jar
  LD_LIBRARY_PATH=3D$JNI CLASSPATH=3D$CLASSPATH java SimpleGladeExample

My $JNI (/usr/lib/jni) contains the files:
libgnomejava2.8.so
libgtkjava2.4.so
libgladejava2.4.so

My $CP (/usr/share/java) contains:
gnome2.8.jar
gtk2.4.jar
glade2.8.jar


If you're missing any of the files (or you're using much older versions)
the program will likely be failing. If I find the time I'll put up an
example that's a bit simpler and won't utilize the gnome libraries....

Oh... and by the way. Mark was right: I had so much trouble converting
"<" and ">" that I accidentaly left some bugs in the example... dunno
how the two 'static's got lost :-)


Have fun.
  Benjamin

PS:
By the way: if any of you guys who really know how to handle java-gnome
(see... I just started using it and really dunno much 'bout it, yet!)
could have a look at what I wrote concerning threads?
http://java-gnome.sourceforge.net/cgi-bin/bin/view/Main/MultiThreaded
Just in case that's stuuupid, too :-)

Guys, Java-Gnome is needing some better skin... it's a hard to read a text like that, so badly
formatted. And things are a little bit too grey-ish... could use some white background (white is
great for reading). If you want i could even help with the css stuff.

Cheers,
J.V.

Hi,

We're currently in the process of updating how we do documentation. The website
unfortuntately has broken links. We are fixing them, but slowly since we're only
doing this in our free time. The old java-gnome tutorial used to be the only
docs we had. The wiki and HintsAndTips page is an attempt to improve the
situation by allowing anybody to add and edit documents. In this case, the
author clearly hasn't even tried to comile the code. Please do correct the
errors on the wiki page.

adding the keyword static to the field declarations for those will fix this

add import org.gnu.gtk.*;
