Re: [platform-swt-dev] Support for JSR-198 (was SWT port for Swing!)

I really dislike the characterization of SWT as "not pure Java". The
truth of the matter is that, SWT is closer to being written in pure Java
than AWT is. At least in SWT, most of the interesting work is done above
the level of the natives.
There is a world of difference between Java binaries and native
binaries. And 100% Pure Java is not simply a marketing slogan.
I agree that the implementation approach used for the AWT toolkits in
Sun's JDK & JRE was (and is) deeply flawed (ditto for most of the rest
of the non-JVM code in the JDK).
I also agree SWT's approach to host system API and implementing the
toolkit layer in Java is superior. That is why I care about SWT at all,
because I see it as important that Java adopt a standard method for
writing code for the operating system-specific APIs. Clearly it will
benefit the GUI situation.
The real problem, which you see as "pure Java-ness", is just that the
SWT libraries don't ship with the standard Java installs. It makes more
sense to attempt to fix that problem than it does to code an SWT on top
of AWT. Ugh.
I agree again. That is going to require a JSR to go through the JCP.
And part of that effort is bound to the requirement for a SWT
implementation that is 100% Pure Java, at least back to the level of JDK
1.2 compatibility (JDK 1.1 would be even better).
It will also require an AWT-SWT interoperability API that functions
equivalently regardless of whether it is the SWT or AWT which is
implemented natively (having both native is a special problem but
certainly could use the same API).

I have been committed for many years to Open Source Java GUI API and was
(am?) the Netscape DevEdge Champion for IFC. It is/was a really great
GUI and a builder tool that has yet to be surpassed. Yet it died as
result of bad decisions by both Sun and (I believe) IBM. I'ld hate to
see that happen to SWT, Java's last best hope for fixing the GUI.

My contribution to SWT/Eclipse was Motif and GTK+ ports for Mac OS X.
They garnered no interest (and deservedly so I suppose):
