Zope3 UI Layer, resource and viewlets bundles for ExtJS v3 JavaScript library


Download ExtJS v3.x (http://extjs.com/products/extjs/download.php) and put it in your operating system anywhere. For example for me it is the following path: /usr/lib/ext-3 Within this folder must be located extracted ExtJS v3 framework distribution.

Anywhere in you project register resource directory has named as ext-3. For example:


This package will looking for the resourceDirectory named ext-3, so it's important that you use the same name in the resourceDirectory statement.

How to use?

This package provide two Viewlet Managers: IExtLayerCSS and IExtLayerJavaScript. You may use it in you project skin template. For example like this:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"
    <meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
    <meta http-equiv="cache-control" content="no-cache" />
    <meta http-equiv="pragma" content="no-cache" />
    <tal:block replace="structure provider:IExtLayerCSS" />
    <tal:block replace="structure provider:IExtLayerJavaScript" />

Or derive/implement your own managers for falkolab.ext3.layer.IExtLayerCSS and falkolab.ext3.layer.IExtLayerJavaScript interfaces.

NOTE: For necessary script including order, please use ordered manager: zope.viewlet.manager.WeightOrderedViewletManager

This package contain several viewlet bunles for ExtJS. Use one of them according base library you use:

ext-all.css All ExtJS library CSS styles.
ext-standalone ExtJS library with own adapter (without any external dependences). IExtStandaloneLayer and IExtStandaloneDebugLayer layers.
ext-jquery ExtJS library with jQuery adapter (WARNING: read note below). IExtJQueryLayer and IExtJQueryDebugLayer layers.
ext-yui ExtJS library with YUI adapter (WARNING: read note below). IExtYUILayer and IExtYUIDebugLayer layers.
ext-prototype ExtJS library with Prototype adapter (WARNING: read note below). IExtPrototypeLayer and IExtPrototypeDebugLayer layers.

NOTE: For bundles which dependet on external library jQuery, YUI or Prototype you must manualy register corresponding resources in your project and place it to your template before this package inclusions. Please see http://extjs.com/learn/Ext_Getting_Started#What_is_the_proper_include_order_for_my_JavaScript_files.3F for details.
