<h1>How to Add a PrefsTree Pref Editor Widget to a CCK Wizard Page</h1>
|
|
|
|
<h2>Introduction</h2>
|
|
The Pref Editor is a widget for CCK/Factory, named <i>PrefsTree </i>in
|
|
.ini files. It is a tree control which displays prefs in a hierarchy and
|
|
allows a user to edit their values. It reads an XML file to determine the
|
|
structure of the tree control. The details of the XML file format can be
|
|
found in the document <a href="PrefsTreeFileFormat.htm">PrefsTreeFileFormat.htm</a>.
|
|
That document, together with this one, describe how to add a pref editor
|
|
tree control to CCK.
|
|
<h2>Example</h2>
|
|
The easiest way to understand how to add a PrefsTree pref edit widget is
|
|
