Label Image Element

• Demonstration: N/A
• Java API: LabelImageElement
• JavaScript API: LabelImageWidget

Employment/Purpose

An HTML element with a label and an image.

Preload Image

Since 6.0.0

The feature is applied to all of the LabelImageElement and Image components.

By default the preload function is disabled, so users have to specify the custom-attributes and set it to true. For example,

<button image="xxx.png">
  <custom-attributes org.zkoss.zul.image.preload="true"/>
</button>

Or specify it just below the root component.

For example,

<window>
  <custom-attributes org.zkoss.zul.image.preload="true"/>
  <button image="xxx.png"/>
  <image src="xxx.png"/>
</window>

As you can see, the custom-attributes will be checked recursively (see also Scope.getAttribute(String, boolean)).

Since 6.5.2

The feature can also applied from zk.xml as a library property.

For example,

<!-- zk.xml -->
<zk>
    <library-property>
        <name>org.zkoss.zul.image.preload</name>
        <value>true</value>
    </library-property>
</zk>
