Joel,
Good to hear from you! That sounds great. I don't do that sort of pathway
business, but I can see that if I did, this would be the way to go. It is
Java based, but there is no indication that they were able to port that
directly to JavaScript. To me it sounds like they started from scratch.
Which is what we are trying to avoid.
What SwingJS is about is taking a *pure*, functional Java applet (or main
program, for that matter) and just transferring that to JavaScript and
having it on a web page in short order. A second little applet is on its
way -- http://chemapps.stolaf.edu/swingjs/site/swingjs/Boltzmann.htm This
one demonstrates using an independent thread that smoothly handles both
multi-cycle calculations and periodic rendering. It's definitely slower
than Java. Also shows simple text boxes and text areas. Nothing fancy, but
I think with 2D graphics, buttons, labels, text fields, and text areas one
can do a lot. I don't see any issues with other basic controls; still
haven't thought about popup menus, but since those are working in Jmol,
that suggests they should be no trouble to implement in their basic form.
I think the basics are worked out now. The thread business works very
nicely; basic controls will have some differences in JavaScript than in
Java, but mostly they function the same.
Lots of blanks to be filled in, but I'm optimistic we can have Jalview and
VARNA working without too much trouble. Those are my target applets for the
summer.
