NumericStepper.previousValue

Availability

Flash Player 6 (6.0.79.0).

Edition

Flash MX 2004.

Usage

numericStepperInstance.previousValue

Description

Property (read-only); the previous sequential value. This property can contain a number of up to three decimal places.

Example

The following example sets the initial value of the NumericStepper instance to equal the minimum value of 6. It sets the stepSize value to 3 and creates a listener object for a change event. When a change event occurs, the example displays the previousValue property in the Output panel.

Drag an instance of the NumericStepper component onto the Stage, and enter the instance name my_nstep in the Property inspector. Add the following code to Frame 1 of the timeline:

/**
 Requires:
  - NumericStepper component on Stage (instance name: my_nstep)
*/

var my_nstep:mx.controls.NumericStepper;

my_nstep.minimum = 6;
my_nstep.value = my_nstep.minimum;
my_nstep.maximum = 120;
my_nstep.stepSize = 3;

// Create listener object.
var nstepListener:Object = new Object();
nstepListener.change = function(evt_obj:Object) {
 trace("previous value = " + evt_obj.target.previousValue);
}

// Add listener.
my_nstep.addEventListener("change", nstepListener);
