Employment/Purpose

An edit box for holding a constrained integer.

Example

 <window title="Spinner" border="normal" width="150px">
     <spinner />
 </window>

In-place Editing

Fixed Width

<spinner width="100px" inplace="true" value="30" />

Dynamic Width

Because inplace editing function in ZK is pure client side action, so we can use client api to modify the width (server side do not need to know)

<zk xmlns:c="client">
  <spinner inplace="true" value="240" width="30px" c:onFocus='this.setWidth("60px")' c:onBlur='this.setWidth("30px")' />
</zk>

Properties

Constraint

You could specify what value to accept for input controls by use of the constraint property. It could be a combination of no empty and the minimum and maximum to spinner.

To specify two or more constraints, use comma to separate them as follows.

<spinner constraint="no empty,min -2 max 6"/>

If you prefer to display different message to the default one, you can append the error message to the constraint with a colon.

<spinner constraint="no empty,min -2 max 6: between -2 to 6"/>

Notes:

• The error message, if specified, must be the last element and start with colon.
• To support multiple languages, you could use the 「l」 function as depicted in the Internationalization chapter.

<spinner constraint="no empty,min -2 max 6: ${c:l('err.msg.spinner')}"/>
