<input type="masked" mask="( ### ) ### - ####" />

that have this behavior applied by default (see master style sheet):

• <input type=“mask” /> - inline single line
• <widget type=“mask”></widget>

• value=“text” - initial value of the input element.
• mask=“text” - input mask string. Characters with the special meaning in the string:
  • # - decimal digit position.
  • _ - alphabetic character or digit position.
  • @ - alphabetic only character position.

• EDIT_VALUE_CHANGED event - value of the element was changed due to user actions. Posted (asynchronous) event.
• EDIT_VALUE_CHANGING event - sent when value of the element is about to change. Synchronous event.
