java-gnome-developer — For people using the bindings to write their own applications

[Java-gnome-developer] RE: Mark Howard's Blog

[Jerry H. <jh...@fe...>]

You seem to think Java is not used for Open Source work. You may in fact
be correct at least for highly visible applications. How many public
Desktop applications do you know of that are written in Java? I can
count them on one hand. But library's? Hundreds of not thousands. Just
look at Jakarta! Hibernate, Castor. There are tons of examples.

Behind the scene, Java is used immensely. Desktop applications inside
corporations, when not built using some Microsoft language, are almost
always Java. You rarely hear about these unless you work for a company
in question.

Where does Java-Gnome fit in? I'm not entirely sure. I recently
discovered it while looking for a solution for my company's in house
applications. We were originally however going to go with SWT. However,
what changed our minds was the potential for RAD that Java-Gnome offers.
Combined with Glade it is an unbeatable combination. I also think the
API is quite a bit cleaner than SWT. I really like it!

Hacking on Java-Gnome is something I am really interested in. I have a
lot of ideas I am working on right now. A major stumbling block I am
hitting is the build system you mention.

I find the need to write JNI bindings for each widget that you want to
wrap unnecessary and excessive. I would like to create GObjects from
within Java (overriding TreeModel), so I am working on these things. Is
anybody else? (Being able to inspect GObject vmethods would sure
help!!!)

After this, integrating a Glade designer into Eclipse should be a snap.
One I'd be happy to work on. This is where it's at guys! We have an
amazing potential for RAD that I can only classify as "kind of like VB".
Quick prototyping and usage of widgets and forms. The difference being
Java doesn't suck. ;)

More visibility would help. It took me awhile to realize that there was
even a Java-Gnome.

If you'd like to hear some more of my ideas about getting rid of JNI,
let me know. I have a lot of them. :0

Hi,

Java-gnome 2.x has small example applications built into it. 0.8 is now
extremely old and deprecated. Please condiser upgrading to 2.6

Re: [Java-gnome-developer] Java Gnome Code generator

[Mark H. <mh...@ti...>]

The code generators were used to create the original bindings. We have not used
them since. Conversion to using Strings instead of byte[] was done manually, as
was writing most of the interfaces.

[Java-gnome-developer] Java Gnome Code generator

[Ashish G. <ash...@gm...>]

Hi 
  i am trying to generate JNI wrappers for C library using Java-gnome
code genrator (version 2.6.1). What i understand is code generator
utilises JNIprops.txt file for conversion of data types between C and
Java. I find corresponding to (char*) there is byte [] defined in
JNIprops.txt so there should be byte array in generated code but if
you see the Java code it has String instead of byte array. Am i using
some different code generator or can some one explain how to generate
String instead of byte array.
 
Thanks

[Java-gnome-developer] Re: About window

[Rishabh M. <rma...@gm...>]

I have been fooling around some more and this is what I have got now:-
I get this error when i try to open the About window:

I have changed the method for activating the about window to look like this:

public void on_about1_activate(MenuItemEvent event) {
                String title = "Java Fortune Teller";
                String version = "Version " + appVersion;
                String license = "(c) Rishabh Manocha. Released under
the(GPL). See COPYING for details.";
                String[] authors = { "Rishabh
Manocha(rma...@cs...)" };
                String[] documenters = { "Rishabh Manocha" };
                String comments = "jfortuneui is a graphical/frontend
interface to the command line program jfortune.";
                About about = new About(title, version, license,
comments, authors, documenters, "", null);
                about.show();
}

I get the above error string when i sue Gtk.init(args) in main instead
of the code given in the tutorial:
Program.initGnomeUI("jfortune", jfortuneui.appVersion, args);
with this command the window does open but nothing can be done with
it, while with Gtk.init(args) the window does not open at all, it only
displays the above error string.
can someone decode it for me and tell me what I might need to add/remove.
Thanks

taken care of etc.(I am using glade...and I love it).
I have one small problem though. Whenever I open the about

It was working when i initially made the design using glade. But then

I think he means new Radiobutton( new RadioButton[0] {}, string, bool)

Alternatively, you could cast the null to one of the two alternatives:
(RadioButton) null

Yeah, I tried that and ended up being tricked by the same inadequacies
of UIInfo that you were. It's just not a very good way to do things.=20

What I've settled on is using libglade for basic window layout, because
it's really good at taking care of all the mundane property setting l
(like packing on VBoxs, window sizes, gravity, etc) - and then I use
straight up GTK calls to add elements to the UI as I need them.

In particular, I've been testing libgtkhtml. There is *no* Glade support
for GtkHtml widgets (that's not a Java issue - it's a Glade one). Rather
than giving up on glade, I simply get the container that's where I want
to put the widget from libglade (in this case "vbox1"):

	LibGlade	glade	=3D null;
	HTMLView	gtkhtml	=3D null;

	try {
		glade =3D new LibGlade("htmltest.glade", this);
	} catch (Exception e) {
		e.printStackTrace();
	}
	=09
	VBox vbox =3D (VBox) glade.getWidget("vbox1");

instantiate the GtkHTML widget,

	HTMLDocument doc =3D new HTMLDocument();
	try {
		doc.loadFile("htmltest.html");
	} catch (Exception e) {
		e.printStackTrace();
	}

	gtkhtml =3D new HTMLView();
	gtkhtml.setDocument(doc);
	gtkhtml.setMinimumSize(10,40);

and then pack the widget on the end of the vbox.

	vbox.packEnd(gtkhtml, true, true, 0);
	vbox.showAll();

Works pretty well.

hey guys,
I changed the createMEnu section to so(I noticed that App has a method
called setMenuBar which accepts a MenuBar object):

public void createMenu() {
		MenuBar bar = new MenuBar();
		MenuItem child = new MenuItem("File",false);
		Menu file = new Menu();
		MenuItem quit = new MenuItem("Quit",false);
		quit.addListener(new ItemListener() {
			public void itemEvent(ItemEvent event) {
				fileExit();
			}
		});
		file.append(quit);
		child.setSubmenu(file);
		bar.append(child);
		this.app.setMenuBar(bar);
	}

However this does not show a menubar at all. I feel I am so close but
yet so far.
Could someone pleaaaaase help me.
Thanks

For which object do I call the addListener method. I am using an array
of UIInfo objects for the menu items and then just add them to the APP
object running the whole show. I dont see where i need to add the
addListener method. Could you help me out with this?

[Mark H. <mh...@ti...>]

I've only looked at this quickly, but it seems that you've defined a listener
for menu item events but not told the menuitems to use that listener. To make
them use a listener, you must call MyMenuItem.addListener( MyMenuItemListener )
for each of them. 

One probably more important recommendation I have is to try using glade instead

development of the glade tutorial is stalled at the moment, but you should be
able to pick it up easily enough. Ask here if you need more help

This is a Java error, the first argument that you pass: "null" , can be
interpreted both as RadioButton or as RadioButton[], which confuses the
compiler.

Why not use RadioButton(0)? This could work...

[Java-gnome-developer] RadioButton - needs some help.

[Abd S. S. <ko...@ax...>]

This is my code:
================
public class test
{
	public  static void create_button(String label)
	{
	RadioButton radiobtn = new RadioButton(null,label,false);
	}
}

After i compile with javac, the error is like this :
----------------------------------------------------
test.java:23: reference to RadioButton is ambiguous, both method 
RadioButton(org.gnu.gtk.RadioButton[],java.lang.String,boolean) in 
org.gnu.gtk.RadioButton and method 
RadioButton(org.gnu.gtk.RadioButton,java.lang.String,boolean) in 
org.gnu.gtk.RadioButton match
        RadioButton radiobtn = new RadioButton(null,label,false);
                                                        ^
Anybody can help? Or may be needs to do something with RadioButton Class 
in java-gnome ??

[Java-gnome-developer] Some questions from the tutorial.

[Rishabh M. <rma...@gm...>]

Hey guys,
I am a new user of java-gnome and let me just start off by saying
thank you to all the developers who have provided this great library.
I am new to dsigning GUI's so excuse my naiveity.
I was going through the tutorial given on the main java-gnome site.
Everything seems to work fine. Only that when I click the Quit button
or the Help/About button, I get nothing. As far as i can see through
the code, I think both of these click should lead to their respective
events?
I am attaching my java file along with this e-mail for you guys to look over.
Oh and my specs: debian sid kernel 2.6.4 with the Sun 1.4.2 sdk compiler and VM.
Thanks

I am sad to admit that I haven't had a chance to look at it.
I will try to take a look in the next couple of days.

It turns out there's a [need-approval-to-join] list called java-gnome-
hackers which is where the development of java-gnome takes place, this
list being intended for people *using* the gnome java bindings to
actually write stuff.

There hasn't been much traffic there either, but if you're submitting
patches that's probably where they should go.
