Hlayout

Hlayout

• Demonstration: N/A
• Java API: Hlayout
• JavaScript API: Hlayout

Employment/Purpose

The hlayout component is a simple horizontal oriented layout. Each component placed in the hlayout will be placed horizontally in a row.

Notice that hlayout and vlayout do not support splitter. If you need it, please use ZK Component Reference/Layouts/Hbox and ZK Component Reference/Layouts/Vbox instead.

Example

<zk>
     <vlayout>
         <button label="Button 1"/>
         <button label="Button 2"/>
     </vlayout>
     <hlayout>
         <button label="Button 3"/>
         <button label="Button 4"/>
     </hlayout>
</zk>

Spacing

The default spacing between two child components is 0.3em. You could modify it if you like:

<vlayout spacing="0">
  <textbox/>
  <button label="Click Me"/>
</vlayout>

Vertical Alignment

[since 5.0.5]

By default, the vertical alignment is middle (aka., center). You could change it to top by specifying sclass="z-valign-top", while bottom by sclass="z-valign-bottom". For example,

<vlayout>
    <hlayout>
        center: <textbox/>
    </hlayout>
    <hlayout sclass="z-valign-top">
        top: <textbox/>
    </hlayout>
    <hlayout sclass="z-valign-bottom">
        bottom: <textbox/>
    </hlayout>
</vlayout>

IE6 Limitation

Notice that, since the vertical alignment is specified in the CSS class (Component.setSclass(String)), there is some limitations for IE6. First, the vertical alignment is inherited to the inner hlayout. Thus, you have to specify the middle alignment explicitly in the inner hlayout, if you need it. For example,

<hlayout sclass="z-valign-bottom">
    bottom: <textbox/>
    <vlayout>
        <hlayout sclass="z-valign-middle">inner: <textbox/></hlayout>
    </vlayout>
</hlayout>
