It's a very simple UI widget to restrict integer and double input into regular TextField. At this moment, it works powerfully with just two types. Integer type just allows digits (0-9) and negative signal (-) at the beginning. Double type allows digits (0-9), negative signal (-) at the beginning, and decimal separator. The decimal separator used is the same of application locale, if you need to change it, use application setLocale(). Features: - Integer and Double restrict numerics characteres. - Double complete with decimals until scale defined (e.g. [scale=4] "10.12" -> "10.1200") - Double fills the field without decimal separator (e.g. [scale=2] "10" -> "10.00"). - Double put a zero at the beginning if the user leave it without (e.g. ".12" -> "0.12") - Double removes* excessive decimals (e.g. [scale=2] "10.8987" -> "10.89") - Accepts validator to certify the value at server side. - Default Double/Integer validator preconfigured - see on code example. * Removes, not rounds the value. In future, we'll be better: - Per mille sign. - Currency symbol.
