[Java-gnome-developer] Cross-process Embedding

[Josh H. <jos...@ho...>]

Hello all,

I am in the process of creating a shared library that handles cross-process 
embedding of windows in a GTK+ gui.  While the passing of windowIDs has been 
implemented in C using the GTKPlug and GTKSocket scheme, the Java bindings 
appear to only contain a Plug class.  The constructor for the Plug class 
requires an argument of type Handle, which itself has no constructor.  The 
API says Handles represent a pointer to a native peer, but I am unaware of 
how to construct anything but a null Handle.

Is this embedding implementable in Java-GTK+?

How is a Plug Handle constructed, and can it be constructed from types int 
or GTKNativeWindow?

Best Regards,
Josh Hope

Really? Huh. Hm. Oops; Bug.

Certainly.

Like all open source software, java-gnome is what people create. If I
had to guess, this shows the classic signs of being something for which
no one who knew what they were doing [and more to the point what they
wanted and how it is supposed to work].

Given that you do, it'd be terrific to get GtkPlug/GtkSocket working...

In rough order, we'd need:

1) an API that makes sense
2) some notion of what needs to be implemented
3) patches :)

If you want to pick this up, I'd suggest starting out with a
skeleton/snippet of what using this might look like. If you were to
write that in an email to jav...@li...
and/or open a bug against java-gnome:libgtk-java that'd be great!

I've attempted this personally in the past, but as we had no concept of a
GdkNativeWindow, I stopped my work and dropped the issue. From the
gdktypes.h header file, we see that...

#ifdef GDK_NATIVE_WINDoW_POINTER
typedef gpointer GdkNativeWindow;
#else
typedef guint32 GdkNativeWindow;
#endif

I'm unsure as to whether this is a big issue or not as my proficiency in C
is rather poor, but I present this information to you all anyway in hopes
that it may be useful for would-be implementors.

Regards,
Rem
