NumericStepper class

Inheritance MovieClip > UIObject class > UIComponent class > NumericStepper

ActionScript Class Name mx.controls.NumericStepper

The properties of the NumericStepper class let you set the following at runtime: the minimum and maximum values displayed in the stepper, the unit by which the stepper increases or decreases in response to a click, and the current value displayed in the stepper.

Setting a property of the NumericStepper class with ActionScript overrides the parameter of the same name set in the Property inspector or Component inspector.

The NumericStepper component uses the Focus Manager to override the default Flash Player focus rectangle and draw a custom focus rectangle with rounded corners. For more information, see Creating custom focus navigation in Using Components.

Each component class has a version property, which is a class property. Class properties are available only on the class itself. The version property returns a string that indicates the version of the component. To access this property, use the following code:

trace(mx.controls.NumericStepper.version);

NOTE

The code trace(myNumericStepperInstance.version); returns undefined.
