RE: [flexcoders] Restrict NumericStepper to only numeric characters

[Paul Kukiel]

Thanks Alex,

 

I was able to get this working.  I was already using a subclass of
numericStepper.  Here is the code if anyone needs to use it:

 

package classes

{

 

      import flash.events.Event;

      

      import mx.controls.NumericStepper;

      import mx.controls.TextInput;

      import mx.core.mx_internal;

      import mx.formatters.NumberFormatter;

      

      use namespace mx_internal;

      

      public class NumericStepperFormatted extends NumericStepper

      {

            public function NumericStepperFormatted()

            {

                  super();

                  

                  addEventListener(Event.CHANGE, handleChange);

            }

            

            private function handleChange(e:Event=null):void

            {

                  var nf:NumberFormatter = new NumberFormatter();

                  nf.precision = 2;

                  nf.useThousandsSeparator = false;

                  

                  var txt:TextInput = mx_internal::inputField;

                  txt.restrict = "[0-9\.]";

                  var formatted:String = nf.format( Number(txt.text) );

                  

                  //add a leading 0 for values that are missing a leading 0

                  if ( formatted.indexOf(".") == 0 )

                        formatted = "0" + formatted;

                  

                  txt.text = formatted;

            }

            

            override protected function commitProperties():void

            {

                  super.commitProperties();

                  

                  //since commit properties is the only method that

                  //calls setValue without dispatching the change

                  //event, we need to make sure we update the value

                  //here too

                  handleChange();

            }

      }

}

 

 

Paul.

I can't think of a supported way to do it, but you can subclass, get the
mx_internal inputField, and change its .restrict property

Anyone know a simple way or a prebuilt adaption of NumericStepper that
restricts Restrict NumericStepper to only numeric characters only.  I need
to stop the user inputting commas.
