Groupbox

Employment/Purpose

A group box is used to group components together. A border is typically drawn around the components to show that they are related. The label across the top of the group box can be created by using Caption component. It works much like the HTML legend element. Unlike Window, a group box is not an owner of the ID space. It cannot be overlapped or popped up.

Example

ZKComRef Groupbox Example.png

 <groupbox width="250px">
     <caption label="Fruits"/>
     <radiogroup>
         <radio label="Apple"/>
         <radio label="Orange"/>
         <radio label="Banana"/>
     </radiogroup>
 </groupbox>

Java Example

Groupbox gb = new Groupbox();

new Caption("Here is Caption").setParent(gb);

gb.setMold("3d");
gb.setWidth("200px");
gb.appendChild(new Label("Here is Content"));

// register an onOpen event.
gb.addEventListener(Events.ON_OPEN, new EventListener() {
	public void onEvent(Event event) throws Exception {
	if (((OpenEvent)event).isOpen())
		//do something you want.
	}
});
gb.setParent(outer);

Properties

ContentStyle

Specify the CSS style for the content block of the groupbox.

ZKComRef Groupbox ContentStyle.png

<groupbox width="250px" mold="3d"
    contentStyle="border: 3px blue dashed;border-top:0px">
    <caption label="Fruits"/>
    <radiogroup>
        <radio label="Apple"/>
        <radio label="Orange"/>
        <radio label="Banana"/>
    </radiogroup>
</groupbox>

ContentSclass

Specify the CSS class for the content block of the groupbox.

ZKComRef Groupbox ContentStyle.png

<zk>
<style>
.mygroupbox-cnt {
    border: 3px blue dashed;
    border-top:0px
}
</style>
<groupbox width="250px" mold="3d"
    contentSclass="mygroupbox-cnt">
    <caption label="Fruits"/>
    <radiogroup>
        <radio label="Apple"/>
        <radio label="Orange"/>
        <radio label="Banana"/>
    </radiogroup>
</groupbox>
</zk>

Closable

Default: true

Specify whether the groupbox can be collapsed or not.

For example,

<groupbox width="250px" mold="3d" closable="true">

Note: the function can only be applied when the Caption exists.

Open/Close

Default: true

Specify the display of the groupbox, whether it is open or closed. For example,

<groupbox width="250px" mold="3d" open="false">

Note: false means the groupbox is closed, i.e. no content can appear.

Limitation of the Default Mold

The default mold of groupbox uses HTML FIELDSET to represent a groupbox visually. It is efficient, but it has some limitations:

  1. The look might be different from one browser to another
  2. The real width and height might not be exactly the same as the specified value in some browsers, such as Firefox.

If it is an issue, you could use the 3d mold instead.

Groupbox-3d.jpg

 <groupbox width="250px" mold="3d">
     <caption label="Fruits"/>
     <radiogroup>
         <radio label="Apple"/>
         <radio label="Orange"/>
         <radio label="Banana"/>
     </radiogroup>
 </groupbox>

Since 6.0.0

The default mold uses the same method as 3d mold to represent a groupbox, the limitation is gone.

Configure to Use the 3d Mold as Default

If you prefer to use the 3d mold as default, you could configure ZK by adding the following to /WEB-INF/zk.xml

<library-property>
    <name>org.zkoss.zul.Groupbox.mold</name>
    <value>3d</value>
</library-property>

Supported Events

Name
Event Type
onOpen
Event: OpenEvent

Denotes user has opened or closed a component. Note:

unlike onClose, this event is only a notification. The client sends this event after opening or closing the component.

It is useful to implement load-on-demand by listening to the onOpen event, and creating components the first time the component is opened.

Supported Molds

Available molds of a component are defined in lang.xml embedded in zul.jar.
