Jmol developers and users -- applet:
I'm developing a simple JavaScript interface that could in principle
replace many or all requirements for applet callbacks. The development
page is at
http://www.stolaf.edu/people/hansonr/jmol/test/json/json.htm
This uses a so-far-unreleased version of the Jmol applet. I'm
interested in whether this page works for you, especially if you have
a Mac. It uses a communication method we haven't used before with the
applet -- direct synchronous JavaScript, using JSON (JavaScript Object
Notation). That is, you call the function
info=jmolApplet0.getProperty("atomInfo","(selected and not water)")
for example,
and the "info" variable is directly filled with the requested
information. This is in contrast to
jmolApplet0.script()
for example, which does not directly return a value -- operates
"asynchronously".
Two nice examples of what this can do are there:
1. Click on "monitor orientation on/off" and then drag the model
around. Fun, eh?
2. Drag the model with zoom and then click on "load THIS orientation".
You won't see much more than a flutter, yet the model has been
completely reloaded. That's because it uses
info=jmolAppletX.getProperty("orientationInfo")
to first get the current orientation and
info=jmolAppletX.getProperty("fileName")
to get the currently loaded file name, then puts them together into a
single script to reload the file with a set of rotations to reorient
it as before.
Please do give this a try and let me know what you think.
I have some ideas of how we could use this to completely replace
callbacks (replacing them with setTimeout() polling of Jmol properties
instead).
