Correct.
This type of problem frequently arises when building graphics user
interfaces.

You need to write the JavaScript to do this yourself.
When you create the checkbox control it is possible for you to pass in an
identifier (the last parameter) that will be used as the 'name' and 'id'
of the control.
function jmolCheckbox(scriptWhenChecked, scriptWhenUnchecked,
labelHtml, isChecked, id) {
(If you do not pass in a parameter, then the default id/name is
'jmolCheckbox0', 'jmolCheckbox1', ..., etc.)
The checkbox control associated with this id is a normal JavaScript
checkbox control.
When events occur in your UI, you can call
getElementById("yourCheckBoxControlID"), and query/modify the state of the
control to make the state presented to the user consistent.
Sorry ... there is no easy way.

Actually, that is not completely true. This is a generic problem. It is
*possible* that there are user interface libraries written in JavaScript
that provide a general framework to make it easier to do this. I am not
aware of such a thing, but maybe someone else is.
(If a JavaScript and/or GUI guru wants to talk about building a more
general (but very complex) mechanism to support this into Jmol.js then
please post to [EMAIL PROTECTED])
