Re: [Jmol-users] Question: How is Info intended to be used?

Thanks, Bob!  JSmol is really amazing.

Info is now pretty minimalist and I am not reusing it.

I was wondering why Info needs to specify j2sPath given that Jmol seems to
locate the js path without an explicit path name in Info. I think I'm missing
something here that may be important when I deploy my app.

thanks,

Here's a follow on question: Assuming that I've created a Jmol Object using an
Info variable, what happens when I change (say) Info.script instead of calling
the script() function?

The Info object is only used at applet start-up. After that all applet
parameters are transferred (after adding default options to Info itself -- so
that you can inspect that as you have) to the variable applet.__Info, where
applet is your applet object. These values in Info are then never read again
and may be changed when setting up the next object.

It is recommended that you use different Info variables for different applets,
but you don't have to.

Many thanks,

Chuck,

I'm sorry. I misunderstood. I thought you were trying to write Info variable
data to Jmol.setInfo.

Chuck and Angle,

I think I'm in basic agreement with Angle. I look at this as a scratch pad per
the following JS function:

function scratchPad(header, content) {
header = (!header) ? "" : header;
content = (!content) ? "" : content;
if (header == "" && content == "") { Jmol.setInfo(jmolApplet0, content, false);
return null; }
jmolApplet0._infoHeader = header;
Jmol.setInfo(jmolApplet0, content, true);
return null;
}

I write to it as needed using the above - e.g. display pdb header or pdb
content. Storage of a given content/header pair would have to be in some type
of global variable. Long term storage would have to be server side, although
for small bits of information I've used cookies.

Only because I found out the hard way, 10 cholesterol molfile cookies will
break the cookie jar. I did not realize what a pain a broken cookie jar could
be for the user!

Hi, Chuck

this is how I see it (but I may not be right)

There is not "your" variable and "Jmol's" variable. The single Info
variable belongs to the Jmol Object once you invoke getApplet.

What you do is initialize some values/parameters that are part of the
Info variable (which is more properly a Javascript object with many
name/value pairs). Jmol has defaults for all of them and will change
just the ones you state.
So I am not suprised at all that Jmol "writes" in the Info variable.

In summary
1. a single Info variable
2. has defaults for all its properties or parts or parameters
3. the defaults are overwritten by your data
4. Jmol will be using all the time the single Info variable

Ah, of course if you have two Jmols they may use separate Infos,
that's why you need to assign Info in the Jmol.getApplet() call.
