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.

Work with ZK6 MVVM

Icon info.png 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>
