How to use the Feathers DateTimeSpinner component

The DateTimeSpinner component allows the selection of date and time values using a set of SpinnerList components. It support multiple editing modes to allow users to select only the date, only the time, or both.

The Basics

First, let's create a DateTimeSpinner control, set up its editing mode and its range of values, and add it to the display list.

var spinner:DateTimeSpinner = new DateTimeSpinner();
spinner.editingMode = DateTimeMode.DATE;
spinner.minimum = new Date(1970, 0, 1);
spinner.maximum = new Date(2050, 11, 31);
spinner.value = new Date(2015, 10, 31);
this.addChild( spinner );

The value property indicates the currently selected date and time, while the minimum and maximum properties establish a range of possible values. You may omit the minimum and maximum properties, and reasonable defaults will be chosen automatically.

The editingMode property determines how the date and time are displayed.

Add a listener to the Event.CHANGE event to know when the value property changes:

spinner.addEventListener( Event.CHANGE, spinner_changeHandler );

The listener might look something like this:

function spinner_changeHandler( event:Event ):void
    var spinner:DateTimeSpinner = DateTimeSpinner( event.currentTarget );
    trace( "spinner.value changed:", spinner.value );

Skinning a DateTimeSpinner

The skins for a DateTimeSpinner control are divided into multiple SpinnerList components. For full details about which properties are available, see the DateTimeSpinner API reference. We'll look at a few of the most common properties below.

Skinning the SpinnerList sub-components

This section only explains how to access the SpinnerList sub-components. Please read How to use the Feathers SpinnerList component for full details about the skinning properties that are available on SpinnerList components.

With a Theme

If you're creating a theme, you can target the DateTimeSpinner.DEFAULT_CHILD_STYLE_NAME_LIST style name.

getStyleProviderForClass( SpinnerList )
    .setFunctionForStyleName( DateTimeSpinner.DEFAULT_CHILD_STYLE_NAME_LIST, setDateTimeSpinnerListStyles );

The styling function might look like this:

private function setDateTimeSpinnerListStyles( list:SpinnerList ):void
    var skin:Image = new Image( texture );
    skin.scale9Grid = new Rectangle( 2, 3, 1, 6 );
    list.backgroundSkin = skin;

You can override the default style name to use a different one in your theme, if you prefer:

spinner.customListStyleName = "custom-list";

You can set the function for the customListStyleName like this:

getStyleProviderForClass( SpinnerList )
    .setFunctionForStyleName( "custom-list", setDateTimeSpinnerCustomListStyles );

Without a Theme

If you are not using a theme, you can use listFactory to provide skins for the list sub-components:

spinner.listFactory = function():SpinnerList
    var list:SpinnerList = new SpinnerList();

    //skin the lists here, if you're not using a theme
    var skin:Image = new Image( texture );
    skin.scale9Grid = new Rectangle( 2, 3, 1, 6 );
    list.backgroundSkin = skin;

    return list;
