SWT C++ is not a Java/Native hybrid. It is 100%
native C++; it is not a C++ layer on top of the Java runtime. Unlike certain
other C++ toolkits, it is not a C++ layer on top of a C foundation. It is
C++ all the way through. In fact, it could be considered more native than Qt
because SWT C++ (and SWT Java) use the Win32 platform's native widgets
whereas Qt uses emulated widgets. In addition, SWT C++ is built on standard C++
and does not depend on C++ compiler extensions or non-standard preprocessors. It
is a natural experience for C++ developers. For example, on Windows, you can do
everything in Visual C++; there are no special build steps or extra tools to
run. Lastly, unlike much older C++ GUI toolkits, SWT C++ is designed and
implemented on modern C++ and standards-compliant C++ compilers. From the ground
up, SWT C++ is designed to use "smart pointers," templates, exception handling,
and other C++ features that were not chosen or not available when the older C++
GUI toolkits were designed.
SWT C++ is a indeed new toolkit. This new
toolkit is also in its third major release.

Wow!
That sounds great, Grant Gayed!
Thanks a lot for the link.
Just a few more doubts which I think you being an expert may be able to
shed light upon :)
(I am also saving myself going through lengthy docs as well ;)
)
Please do help if you know.
1) We have already written a fair amount of code in SWT Java.
Can it be converted into C++ code by some Pure-Native tool?
2) After we have converted SWT Java code to C++ (by tool or manually),
we should need only a C++ lib of SWT C++ to link with along with some
headers. Is that correct? Please confirm.
Thanks again for the reply.
It really helped me.
Thanks

As mentioned below, the answer is Yes. It's called SWT C++ and it's a
100% native C++ implementation of SWT. It's produced entirely from the SWT
Java implementation. Basically, it is SWT Java source code compiled to C++
source code instead of compiled to Java bytecode. It is like another
platform target for SWT: native C++, requiring no JRE and no JNI. It is
feature-for-feature, bug-for-bug, and pixel-accurate to SWT Java.
Presently, it is at SWT version 3.4.1 and only supported for Win32 desktop
and Win CE (Pocket PC and Windows Mobile), and Visual C++ 8.0 (Visual
Studio 2005) and 7.1 (Visual Studio 2003). Visual C++ 9.0 (Visual Studio
2008) support is working but not released. Other target OS platforms are
being considered.
Regarding the use case " such that even the GUI elements
could be coded in C++ only," this is not supported out-of-the-box, and we
have not pursued this ourselves. That being said, by nature of SWT's
design, it should be entirely possible to re-host an SWT C++ control in a
SWT Java control or an Eclipse Workbench part (either a view or an editor)
along with a JNI wrapper for the SWT C++ control. It may even be possible
to do this without changing SWT C++ at all but no guarantees. There's a
good explanation of how to wrap a native Win32 or Motif control as an SWT
Java control along with JNI DLL on the Eclipse Web site. See the headings
" Wrapping a Native Widget", "Windows Native
Code", and "Motif Native Code" in the following
article:

First to answer your question, there is a project at
http://www.pure-native.com/ that takes an SWT
release and converts it to C++ for use in C++ apps (note: win32 only).
However, if I understand your question correctly, you'll be
writing/re-writing your UI in SWT from scratch, and you want your app to
run as an eclipse plug-in, right? If so, I would suggest writing
your UI using SWT's java implementation. This will make the
integration of your UI into eclipse straight-forward, and will be
cross-platform. You would then use JNI to interact with the
application logic that you want to preserve from your existing C++ app.
