[Zope] Zope Button

[Casey Duncan]

As I think you have found (or not found ;^), there is none. Zope is an ob=
ject=20
publishing system. The cute little folders and file icons you see are jus=
t an=20
illusionary file-system-ish object hierarchy called OFS.

So back to your question, p_ is not a folder at all. It is an object=20
(technically its a class, but that is neither here nor there) which is an=
=20
attribute of (IOW its attached to) the root folder, which is a folder (bu=
t a=20
special one). The p_ attribute is defined in the Zope code as a container=
 for=20
Zope software to put things in that are built into the system.=20

In technobabble terms, it is a special global "namespace" for the Zope=20
software itself to store resources it uses. This namespace is separated=20
(under the name p_) from the rest of the OFS so that you can define your =
own=20
objects with just about any name, including "ZopeButton", without obscuri=
ng=20
the ones in p_.

So where does it come from? ZopeButton comes from a file in your Zope=20
installation. The Zope software wraps this file in a special ImageFile ob=
ject=20
(which knows how to load image files as object) and then "mounts" it in p=
_.=20
There are all kinds of other images in there as well, mostly all for use =
by=20
the ZMI: icons, decorations, other powered by icons, etc. If you don't=20
believe me, check out $Zope/lib/python/OFS/misc_.py
