 </window>

Properties

Format

You are able to format the field by providing specifying the attribute with a formatting string. The default value is null.

<intbox format="#,##0"/>

since 8.5 You can provide a locale to format the number by specify the String starts with “locale:”

<intbox format="locale:zh-TW"/>

Constraint

You could specify what value to accept for input controls by use of the constraintproperty. It could be a combination of no positive, no negative, no zero, no empty.

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

<intbox constraint="no negative,no empty"/>

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

<intbox constraint="no negative: it shall not be negative"/>

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.
<intbox constraint="no negative: ${c:l('err.num.negative')}"/>
