Hi All, I want to implement the java-gnome binding for tray( in libegg). With this feature I hope java application can be more tightly integrated into gnome desktop. For example, a java mail client will launch a tray icon in the notification area when startup. I think it is very useful. Is there any document point me how to do this? Thanks. York |

Hi, I have looked through the examples, and I am silly enough not to work out how to get the current row selected in a treeview/listview. Is there actually an example, if not, could someone show me how this is done? Also, is the cromagnon application included in the 0.82 release? I have it on my pc at home which is an older release (0.8 or 081 I think), however the file structure seems to have changed A LOT in this more recent release. Thanks :) -- [ A n d r e w ] -------|------- |

What do you mean exactly? When you have a treeview widget it should just select a row with a mouse click. Maybe are you asking how to catch the row selected event? > Also, is the cromagnon application included in the 0.82 release? No, it was removed from the distribution in order to become a standalone project. > I have > it on my pc at home which is an older release (0.8 or 081 I think), Last time I've touched CroMagnon it was version 0.2. If you want I'll send you an updated CroMagnon tarball, let me know. -- Luca De Rugeriis <pie...@li...> |

We should probably add a method for this to java-gnome. Please file a
bug report for it.
In my applications, I have added a listener to the selection of the
treeview:
pkgView.getSelection().addListener( watchSelectionChange );
private TreeSelectionListener watchSelectionChange = new TreeSelectionListener(){
public void selectionChangedEvent(TreeSelectionEvent event){
TreeSelectionForEach fe = new TreeSelectionForEach(){
public void forEach(TreeModel model, TreePath path, TreeIter iter){
...
}
};
pkgView.getSelection().forEachSelected(fe);
}
};

Are you subscribed to java-gnome-announce? I did explain the file
structure changes in an announcement of 0.8.2 release.
cromagnon is not included in 0.8.2. It is a little too big for an
example app; and if it is to survive, it should be developed in it's own
project.

Hi, Java-Gnome does not have any support for libegg at the moment. It is unlikely that we will add it in the future either, since libegg changes very quickly. However, the best bits of libegg always move into standard gtk/gnome once they become stable and are accepted as being useful. Once they are there, java-gnome will support them. Our new release schedule means that our support for them will be very shortly after gnome supports them. (For those reading this who don't know, libegg is a library for new widgets which are being developed. It changes very quickly and so is not usually supported by many applications. However, once widgets in libegg are proven to be useful, they are moved into core gtk/gnome libraries) If you do want to add support for this part of libegg yourself, the only documentation that is available is the java-gnome source code itself. you would have to create a new java-gnome module containing jni and java code. This would require quite detailed knowledge of java, jni and of course the libegg api. If you have this, then we would be glad to help out with any problems you encounter (although java-gnome developers are currently very busy adding support for gnome 2.5, so we might be a little slow in responding at the moment) -- .''`.

Hi Mark and all,
My tray icon now working very well in java application. Thanks
java-gnome developer team!
However, some small problem leaved unresolved.
1. I use tools/DesProcessor to generate jni/java code. But the
generated jni default prefix to
org_gnu_gnome_XXX. How can I control it? For example, I want to
prefix them
to org_gnu_egg.
2. The function egg_tray_icon_new has parameter of char * , so in my defs:
(define-func egg_tray_icon_new
EggTrayIcon
((string name)))
The generated java code, the native interface is defined as:
... ...
native static final protected int egg_tray_icon_new (byte[] name);
... ...
Thus 'String' in defs is convert to 'byte[]' in java. But I found in
some gtk functions, ('string name') in defs is convert to 'String' in java.
I like this way. But how can I generate 'String' instead of 'byte[]'?
Thanks

I wasn't in the project then the defsProcessor wwas being written. A simple sed line would change them all though. > 2. The function egg_tray_icon_new has parameter of char * , so in my defs: We don't actually use the defs processor any more. We now more or less write everything by hand. We completely changed the way we handled strings, but never updated the defs processor. Please take a look at the gtk/TextView for an example of how we handle strings now - it is a lot simpler (and more efficient) than using byte[]. -- .''`.
