LabelImageElement


Label Image Element

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 properity.

For example,

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

IconSclass

[since 7.0.0]

ZK 7.0.0 integrate FontAwesome 4.0.1 with prefix z-icon. To use it, just add iconSclass attribute.

For example, add home icon on Button,

<window>
    <button iconSclass="z-icon-home" />
</window>

If you want to use other Font Awesome function such as animation icon, you can include the external font awesome CSS link and add the CSS class to iconSclass too. For example,

<?link href="http://netdna.bootstrapcdn.com/font-awesome/4.0.1/css/font-awesome.css" rel="stylesheet"?>
<window>
    <button iconSclass="z-icon-bell fa-spin" />
    <button iconSclass="z-icon-home fa-2x fa-rotate-90" />
</window>
[since 8.0.0]

ZK 8.0.0 upgrade Font Awesome version to 4.3.0. Also, there is no need to include external font awesome CSS link to use animation icon, therefore the example above would be

<window>
    <button iconSclass="z-icon-bell z-icon-spin" />
    <button iconSclass="z-icon-home z-icon-2x z-icon-rotate-90" />
</window>

The iconSclass is not only restricted to font awesome icons ("z-icon-" classes): Any css class can be applied to customize the nested tag, for example, the bootstrap glyphicons can be used there too,

<window>
    <button iconSclass="glyphicon glyphicon-envelope" />
</window>
