RE: [Java-gnome-developer] Gnome Library

[Jeffrey M. <Jef...@Br...>]

We might be able to assist you in two ways.  

1) If you do decide to compile java-gnome on Win32 we 
will try to offer all of the support we can.  There are
others in the community that have expressed interest in
this and they might be willing to contribute.

2) If you find java-gnome classes that need to be enhanced
to support better drawing features please post those requests
to the list.  We will make every attempt to enhance the
bindings.

Hi Fernando,
Thanks for all.
I want my application, a GPL P2P Chat with the possibility to live draw (
unfortunatly only in italian ), runs on all system (at the moment I use
Swing but look&feel is awful).
So I want port my application to SWT, but I want to expand the feature of my
application when it runs on gnome for a better system integration.
After your answer I think that I have two possibility:
1) Try compiling java-gnome using the GTK port for Win32 ( I try GIMP on
windows and it's work very well), so it work on
linux, unix and win system; in Italy there are few Mac system !
2) Using only SWT ( I'm not able to exapand SWT, I'm a 23 years old student
of software engineering).
