[Java-gnome-developer] installing in ubuntu breezy

[Eric K. <er...@um...>]

I am trying to install java-gnome in ubuntu breezy but keep getting the 
following error:

The following packages have unmet dependencies:
  libgnome-jni: Depends: libgnome-java (= 2.10.1-1) but 2.12.1-0ubuntu1 
is to be installed
  libgtk-jni: Depends: libgtk-java (= 2.6.2-1) but 2.8.1-0ubuntu1 is to 
be installed

can anyone help me?

Re: [Java-gnome-developer] special sidebar combobox-style widget

[Adam J. <ajo...@re...>]

Hi Lars,

To the best of my knowledge and what I've been able to glean off the GTK 
docs, no such widget exists in GTK and therefore in Java-GNOME. However, 
implementing such a widget yourself if definitely possible within the 
widget set that GTK (and Java-GNOME) provides, which is probably what 
the people in Nautilus did.

Best of Luck!

[Java-gnome-developer] special sidebar combobox-style widget

[Lars W. <la...@di...>]

Hi everyone,

there's this special type of ComboBox widget that's used in the sidebars
of newer versions of the Nautilus browser or evince for example.  (It's
special mostly in that it appears as a label with a downwards arrow by
default and only changes to a button when the mouse is above it.)  Is
this widget also available in Java-GNOME?  If so, what's it's name?
(I'm not even sure wheter the widget is part of GTK...)

Regards,
Lars

[Java-gnome-developer] ListStore and null in String column

[Damian M. <da...@sp...>]

I wanted to set value to null in a column of ListStore but noticed it is 
actually not null but an empty String.
After investigating the problem I found this :
in

org.gnu.glib.Value
public void setString( String value)
{
        if (value == null)
            value = "";
        g_value_set_string(handle, value);
}

Is this normal? And what about setting the null value ?

Hm. Does this mean that we need to add a addListener(PanedListener) to
Paned and a PanedEvent class with CHECK_RESIZE, MOVE_HANDLE and
ACCEPT_POSITION?

[Java-gnome-developer] JavaGnome with ACR tutorial updated!

[pancake <pa...@ph...>]

I've updated the tutorial about how to use ACR to create './configure' scripts for java-gnome projects. 

The git-devel tree of gdvb is really nice :) now with TDT support.

http://java-gnome.sourceforge.net/cgi-bin/bin/view/Main/UsingACR


PD: How is the libegg development? I would like to appletize gdvb into the notification area like gaim. Someone at irc point me at http://bugzilla.gnome.org/show_bug.cgi?id=330432, but seems that nothing changed since then.

Thanks for this great API.

[Java-gnome-developer] JNI fix-a-thon results

[Adam J. <ajo...@re...>]

Hey everyone,

After the jni cleanup effort by Sami, Andrew and myself we were able to 
find and fix a large number of little buglets that we believe would 
break 64 bit compatibility. We've gotten frysk to run after these fixes, 
and we would like to encourage everyone to try out Java-Gnome on 64 bit 
so we can flush out any further bugs.

Thanks,

Adam

[Java-gnome-developer] signal questions

[Lars W. <la...@di...>]

Hi everyone!

Two questions related to signals/listeners:

1) What am I supposed to do if I want to get notified of position
changes of the handle in a Paned widget?  Connecting handlers to the
check_resize, move_handle or accept_position signals in Glade doesn't
seem to work here and neither does adding a ContainerListener that tests
for CHECK_RESIZE events.

2) For TreeSelections, does anyone know of a clean way to get more
detailed information on what kind of user action changed the selection
(that is, in addition to the fact *that* it changed)?  The problem is
that I'd like to differentiate between replace actions (simple click)
and add/remove actions (Ctrl-click).  (Comparing the selection after
each change wouldn't always work since I need to differenciate the two
actions even in situations where there was previously no item selected.)
Is manually testing whether the Control-key was pressed during selection
the only/correct way to do it?

Thanks in advance for any suggestions!

Regards,
Lars

[Java-gnome-developer] Xlib error (sequence lost in reply type 0x0) on PPC64

[Wu Z. <woo...@cn...>]

Hi,

I am tryig to build and run Frysk, heavily using Java-Gnome, on PPC64.  
The platform I am using is FC5 test2, with all the packages being the rawhide 
(ok, about a week ago).

Frysk build ok and start also ok.  But when I click on a random process in 
the process view, it report Xlib error: sequence lost (0x10000 > > 0x2080) 
in reply type 0x0!  There is no such error in x86 platform.

I am now suspecting that it might be related with Java-Gnome on PPC64 
(anybody else else tried Java-Gnome on this platform, please let me know. :-)

The reason is that when I attach GDB to the running Frysk, I sometimes get 
SEGV signal at cario function, such as:

[Java-gnome-developer] MozEmbed.renderData() doesnt generate net events

[Andrzej B. <ab...@ge...>]

Hi,

I'm trying to load manually a document from a String. While the standard 
MozEmbed.loadURL() method works quite well, the family of methods that 
use MozEmbed.appendData() (including renderData()) don't seem to 
generate the net events when loading of the document is finished (in 
this case, all of the linked content, because the main body is loaded 
manually)...

Also, the net_stop event doesn't necessarily mean that the document is 
rendered in the browser window - sometimes there is a noticeable delay 
between these two events. Is there any event available which says 
something like "everything is loaded AND rendering is finished"?

Hm, ok - so the solution/workaround is to use firefox 1.5? I used the 
Mozilla-1.7.12. I guess I need to install Firefox first + devel 
libraries. Then, how do I tell the java bindings to use the Firefox 
version of the gtkmozembed (if Firefox comes with that library, which I 
don't know)?

Re: [Java-gnome-developer] Problem with MozEmbed.handleProgressAll

[Remy S. <rem...@gm...>]

Hi there,

Please refer to http://bugzilla.gnome.org/show_bug.cgi?id=318944 for
some information on the issue.

In essence, the code was originally using a Handle as a parameter.
However, I believe it was while Ismael was committing a patch that I
had submitted that he came to realize that the examples didn't work for
him, so he changed the callback to accept a String instead. After the
fact, it stopped working for me, which I spoke to him about, and we are
both pretty confused as to why it's like so.

I did not mention this in the bug, but the version in which it does not
work for me is Firefox 1.0.7 (that's not to say 1.0.6 and before it was
all fine for me with using a String, I can't say I remember if I tried
the bindings back then).

In the 1.5 file, it appears to explicitly state String (GTK_TYPE_STRING
| G_SIGNAL_TYPE_STATIC_SCOPE) whereas the 1.0.7 file just says
G_POINTER.

Regards,
Rem

[Java-gnome-developer] Problem with MozEmbed.handleProgressAll

[Andrzej B. <ab...@ge...>]

Hello,

I'm trying to compile and run the TestMoz example, on Fedora Core 5 
beta2. I needed some features from PixBuf, so I had to upgrade all 
java-gnome libraries to their latest CVS versions.

SelfLoadingMoz works flawlessly. But when I try to run the TestMoz 
example, it complains with the following exception:

java.lang.Exception: Java-GNOME - cannot find callback method 
handleProgressAll in the specified object with signature 
(Lorg/gnu/glib/Handle;II)V

This happens when MozEmbed tries to register the NetListener. Any help 
would be highly appreciated - in my application I need to track the 
net_stop event, so that working listeners are rather important... ;-)

Thank you!

[Java-gnome-developer] g_object_remove_toggle_ref warning

[Manuel C. <ll...@us...>]

Hi all,

I'm sometimes getting this message:

(java-gnome:23339): GLib-GObject-WARNING **: 
IA__g_object_remove_toggle_ref: couldn't find toggle ref 0xb1e49940((nil))

The same message repeats about 50 times.

Does this indicates a bug in my code? or in java-gnome code?

How should I debug it?

Thanks!

[Java-gnome-developer] Setting a ComboBox read only?

[Manuel C. <ll...@us...>]

Hi all,

You can setEditable(false) an Entry because it implements the editable 
interface, but how do you make a ComboBox *not* editable? and setting it 
insensitive doesn't count, since it renders the widget in a different way.

I can only think of just putting the correct string in the combo and not 
the not selected options, but this seems overkill.

Any idea?

Thanks!

Hi Andrew,

Thanks!  I think I originally installed (older versions of) the Gentoo 
packages, which sorted out some dependencies for me, but then I ran into 
a bug which you guys fixed within about 24 hours, so I had to use CVS to 
continue.  I see that there are updated Gentoo packages now, and I'll 
give them a try soon.

By the way, I'm giving a presentation at FOSDEM 2006 about my success 
getting JFreeChart to run with GNU Classpath and Cairo.  I've tweaked a 
couple of things in my CairoGraphics2D class and I'm getting some really 
nice output now - I'll put the presentation and all the details online 
after FOSDEM (at the end of the month).  I'm happy to contribute the 
CairoGraphics2D code to cairo-java if you think it fits (I think it does).

Keep up the good work!

Dave

[Java-gnome-developer] java-gnome slowdown

[pancake <pa...@ph...>]

I've just updated the pkgsrc packes of cairo-java, glib-java amb libgtk-java (next ones will be up soon).

But I've noticed about a huge slowdown! about 2x-3x.

Bootup process:
==========
gdvb with libgtk-java-2.6 = 2 seconds
gdvb with libgtk-java-2.8 = 5 seconds.

I understand that gtk-java2.8 uses cairo and glib, and this makes gtk heavier to load...but 2-3x?!

How can this be improved?

Maybe too many checks for initializations? This makes the code secure against posible segfaults on bad code, but makes slower....

any idea? solution? tip?

Thanks

Re: [Java-gnome-developer] ComboBox Events bug?

[Manuel C. <ll...@us...>]

Hi all,

Here is what I found so far:

- It looks that there is no problem in java-gnome: ComboBox as Button 
both extend Bin, and Button is working properly. No code in the 
hierarchy captures the signal or prevents emiting it.

- Attaching a ContainerListener to the ComboBox gives you a 
SET_FOCUS_CHILD event, while doing the same in the Button doesn't.

- Looking at the gtk code, it looks that the combobox grabs the focus to 
some of his childrens, so the combobox itself never gets focus, and 
doesn't emit a focus signal itself.

- Writing a similar example in C gives the same results: the Button 
emits the focus out event and the ComboBox doesn't.

- I'm left to using the SET_FOCUS_CHILD of the Container when using a 
ComboBox.

- It remains for more experienced people to decide if this is a bug / 
design decision from GTK, and people should use SET_FOCUS_CHILD (and we 
need to document it :)).

Examples attached.

See you!

Duplicated.

Manuel, chat with the day-shift guys in Toronto on IRC, but if none of

I've only used FOCUS_OUT once, but it works ok:
http://research.operationaldynamics.com/source/darcsweb/?r=objective;a=headblob;f=/src/accounts/ui/ForeignAmountEntryBox.java#l118

(and two others in that file. I note that I'm using it against an Entry
so that doesn't necessarily prove anything for you. You might want to
have a glance there to make sure you're doing the Listener/Event
correctly, though)

Test cases are always brilliant. They are, of course, hard to generate
in a compact way so I for one always take the time to try them if
someone goes to the trouble.

[Java-gnome-developer] ComboBox Events bug?

[Manuel C. <ll...@us...>]

Hi all,

I'm trying to use the "FOCUS_OUT" event out of ComboBox, since it 
extends from Bin which extends from Container which finally extends from 
Widget, I should able to get the event, right?

I'm attaching a ComboBoxListener and I get the CHANGED event.
I'm attaching a ContainerListener and I _don't_ get any Container event.
I'm attaching a FocusListener and I _don't_ get any focus event.

So it seems that something gets wrong in ComboBox <-> Bin <-> Container.

Can anyone look into this? Should I send a simple example? Any hints to 
fix the bug myself :)?

Thanks!

Just a sidenote: I have begun to write an example program to enable
close button on notebook widget. I have really no idea how to progress
it. So any help is welcome. However I try to make what I can (notebook
example program, etc), and after I hope I can get some help from the
list.

Best regards,
