Employment/Purpose

The component used to represent CKEditor

CKEditor is a popular HTML on-line text editor developed by Frederico Caldeira Knabben.

CKEditor is a text editor to be used inside web pages. It's a WYSIWYG editor, which means that the text being edited on it looks as similar as possible to the results users have when publishing it.

It brings to the web common editing features found on desktop editing applications like Microsoft Word and OpenOffice.

Example

<ckeditor width="850px">
<attribute name="value"><![CDATA[
<table width="200" cellspacing="1" cellpadding="1" border="1">
	<tbody>
		<tr style="background: #B7B313; color:white;">
			<td>First Name</td>
			<td>Last Name</td>
		</tr>
		<tr>
			<td>Jone</td>
			<td>Hayes</td>
		</tr>
		<tr>
			<td>Mary</td>
			<td>Bally</td>
		</tr>
	</tbody>
</table>
]]></attribute>
</ckeditor>

It will turn on the save button when inside a form

<zk xmlns:n="http://www.zkoss.org/2005/zk/native">
	<n:form>
		<ckeditor width="850" />
	</n:form>
</zk>

File browser

ZK CKEditor provides a default file browser for browsing the files in a folder that you specify. You can define a target folder in index.zul and when you open the add image/flash dialog and click "Browse Server", CKEditor will open a new window, and list all the files in the file browser.

File:ZKCompRef CKEditor filebrowser.png

<zk> <ckeditor filebrowserImageBrowseUrl="img"/> </zk>

Custom File browser

since 3.6.0.2

If you wish to customize your own file browser, you can change the location by calling CKeditor.setFilebrowserImageUploadUrl(page_url), and refer to CKEditor Developers Guide to create your custom file browser.

File upload

since 3.6.0.2

ZK CKEditor provides a default file upload handler for uploading the files to the folder you specify. You can define a target folder in index.zul and when user uploads a file, it will save the file in the folder that you have specified.

File:ZKCompRef CKEditor filebrowser.png

<zk> <ckeditor filebrowserImageBrowseUrl="img" filebrowserImageUploadUrl="img"/> </zk>

Custom File upload handler

since 3.6.0.2

If you wish to customize your own file upload handler, you can change the location by calling CKeditor.setFileUploadHandlePage(page_url), and refer to CKEditor Developers Guide to create your custom file upload handler.

Custom Configuration

Prepare a javascript file for configuration like:

config.js

CKEDITOR.editorConfig = function(config) {
    //enable spell checker
    config.disableNativeSpellChecker = false;
    //Automatically enables "Spell Check As You Type" on editor startup
    config.scayt_autoStartup = true;
    //locale
    config.language = 'de';
};

Please refer to http://docs.ckeditor.com/#!/api/CKEDITOR.config for complete configuration options.

Specify the configuration file at customConfigurationsPath attribute with the absolute path.

<ckeditor customConfigurationsPath="/config.js"/>

Custom Save Button

You can implement a custom plugin to enable the save button and fire the onChange event to the server to save the editor's content. Please refer to on the github.

Plugin Installation

1. Download a plugin according to CKEditor version

   ZK Ckedtiror version aligns the bundled CKEditor version.

2. put plugin folder into plugin folder for ckeditor

   In ZK, you have to copy the plugin folder into the folder below: (assuming a Maven project)

   /resources/web/js/ckez/ext/CKeditor/plugins/

3. setup in custom config js

   Then provide a config.js mentioned at Custom Configuration.

Example

1. Download Line Height plugin
2. its js files under

   /resources/web/js/ckez/ext/CKeditor/plugins/lineheight

3. setup in your custom config js

CKEDITOR.editorConfig = function(config) {
     config.extraPlugins = 'lineheight';
}

Work with ZK6 MVVM

Notice: Since Ckeditor 3.6.0.1, we have added data binding annotation into the lang-addon.xml file, so you no more need to add the settings below.

Since 6.0.0

For work with ZK6 MVVM, it is required to create an addon XML and add the server annotation as follows:

WEB-INF/ckez-bind-addon.xml

<?xml version="1.0" encoding="UTF-8"?>
<language-addon>
	<!-- The name of this addon. It must be unique -->
	<addon-name>ckezbind</addon-name>
	<!-- Specifies what other addon this depends
	<depends></depends>
	-->
	<!-- Which language this addon will be added to -->
	<language-name>xul/html</language-name>

	<component>
		<component-name>ckeditor</component-name>
		<extends>ckeditor</extends>
		<annotation>
			<annotation-name>ZKBIND</annotation-name>
			<property-name>value</property-name>
			<attribute>
				<attribute-name>ACCESS</attribute-name>
				<attribute-value>both</attribute-value>
			</attribute>
			<attribute>
				<attribute-name>SAVE_EVENT</attribute-name>
				<attribute-value>onChange</attribute-value>
			</attribute>
			<attribute>
				<attribute-name>LOAD_REPLACEMENT</attribute-name>
				<attribute-value>value</attribute-value>
			</attribute>
			<attribute>
				<attribute-name>LOAD_TYPE</attribute-name>
				<attribute-value>java.lang.String</attribute-value>
			</attribute>
		</annotation>
	</component>
</language-addon>

then add it into WEB-INF/zk.xml

<zk>
	<language-config>
		<addon-uri>/WEB-INF/ckez-bind-addon.xml</addon-uri>
	</language-config>
</zk>

Supported Events

Name	Event Type
onChange	InputEvent Description: Denotes the content of an input component has been modified by the user.
onChanging	InputEvent Description: Denotes that user is changing the content of an input component. Notice that the component's content (at the server) won't be changed until onChange is received. Thus, you have to invoke the getValue method in the InputEvent class to retrieve the temporary value.
