Intbox
Employment/Purpose
An intbox is used to let users input integer data.
Example
While input invalid data:
<window title="Intbox Demo" border="normal" width="200px">
int box:<intbox/>
</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 8.5.2 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 constraint property.
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')}"/>
