Thanks for the patch. It is in CVS. Everybody; it is time. I have tagged the cvs for the next release. I know there are numerous bugs remaining but they will have to wait 8-( Thanks to all of you who have contributed patches, reported bugs, or provided feedback. I hope to have this release out within 24 hours. Luca, I will address the items you reported as soon as this release goes out. What lies ahead? For the next release I hope to continue to address bugs, but I also wish to start adding functionality. There are several areas in which the bindings could be expanded. Please let me know which of the following items you would like to see and in what order: GConf gnome-print Bonobo panel-applet - requires Bonobo gnome-vfs enhancements to gnomecanvas -Jeff > On Tue, 04 Nov 2003 15:07:31 +0200, Jonas Berlin > <jb...@ni...> > wrote: > > > Here's the first patch, which adds all missing java methods for > > Well lol at me..

1. Bug fixes, memory leak detection/fixes (will mostly come from user bug reports for now, I guess). 2. Implementation of gtk-demo in java-gnome gconf - essential (IMHO) for any large application for storing state at least. bonobo - I'd really like to see my bugviewer app running in galeon :) gtkhtml - I think it would be useful. I'd be interested to hear from people who use the c version already. gnome-print - I'd say leave it out for now. I think upstream are making some big changes to it, or planning to. Ximian have a huge patch to rewrite this to look far better, but it only works on systems with cups. There's been quite a bit of debate about it on the Debian mailing lists recently. I'm busy at uni at the moment so unfortunately should not help with java-gnome. Things will hopefully be different in December though. -- .''`.

Elias, the way to do custom components in GTK2 is to have a DrawingArea=20 widget. It's present in java-gnome, too, but currently as Jeffrey said,=20 there's not much that has been done on this front, so you can't do much=20 with it yet, or should I say anything.. =3D) Elias btw have you tried using glade-2 to design the UIs? It works great=20 with java-gnome. For tricky ui:s, you can still choose to create some of=20 the widgets by code. However, as I got a need to write a custom component myself (a complex=20 graph widget for plotting all sorts of data) I thought that I could give=20 it a try to implement the missing methods, or at least the most important= =20 ones. If you don't hear from me on this front in a few weeks then I=20 probably got too busy to finish it. Otherwise, you'll hear from me soon..= =20 wish me luck :) - xkr47 |

It was kind of a bummer. :-) > Elias btw have you tried using glade-2 to design the UIs? It works > great with java-gnome. For tricky ui:s, you can still choose to create > some of the widgets by code. Yes, that's what I used. It works great by the way, even though I would like some more control as to on which handler class the callbacks are called. Maybe there is, if so I'd love to know about it. I had to read the source and try to figure out how it was weant to work. Good work still. :-) > However, as I got a need to write a custom component myself (a complex > graph widget for plotting all sorts of data) I thought that I could > give it a try to implement the missing methods, or at least the most > important ones.

I'll be waiting for it. :-) The test application I intended to write while learning java-gnome was a small paint program. And for that you need graphics methods. :-) Regards Elias |

Here's the first patch, which adds all missing java methods for functions= =20 provided by the native GDK GC. This doesn't add much value currently, but= =20 will be nice to have later when I get the Drawable methods implemented. I= =20 wanted to provide this patch separately, to make future patches more=20 comprehensible. Jeffrey, could you check it and put it into cvs if you find it acceptable= .=20 If you want to discuss the code, that's ok with me, but it should all be=20 pretty simple. If you feel some other active java-gnome developer should=20 be contacted instead, please inform me, thanks =3D) - xkr47 |
