listbox in prefwindow?

[Anthony Lieuallen]

I've successfully set up a <prefwindow> with <checkbox> and <textbox>
items. Now, I want a <listbox> containing a list of multiple string
values. I haven't figured out any way to get that to work.

Does anyone out there have an example of a properly working <listbox>
which the user can add and remove values to/from, set up inside a
<prefwindow> container to handle the preference work?

<prefwidnow> can contain any control, just like a regular window. Some
of them can be tied to a preference so that the preference is
automatically updated as the control is manipulated. Others, like
<listbox>, cannot be so tied, but one can always write a script that
updates preferences explicitly, via nsIPrefBranch interface.

Okay. What confused me though was the fact that the docs of listbox [1]
say:

" preference
Type: element id
Connects the element to a corresponding preference. This attribute
only has any effect when used inside a prefwindow. The value of the
preference will be updated to match the value property of the element."

Just like the other elements that work, no strings attached, with
prefwindow. Is this a lazy copy/paste?

It works similarly to the menulist control - you can associate values
with your listitems and the listbox's value will be the value of the
selected item. The listbox's value attribute is what gets saved to the
preferences.
