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 integrates FontAwesome 4.0.1 with the prefix z-icon. To use it, just add the iconSclass attribute. For a complete list of icons, please refer to FontAwesome Cheatsheet.

For example, to add a home icon on a Button,

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

If you want to use other Font Awesome function such as the animation icon, you can include the external font awesome CSS link and add the CSS class to iconSclass. 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 integrates Font Awesome 4.3.0. Also, with ZK 8 there is no need to include external font awesome CSS link to use animation icon. Therefore the example above becomes

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

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

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