A function that returns a display object to be positioned in the accessory position of the renderer. If you wish to display an Image in the accessory position, it's better for performance to use accessorySourceFunction instead.

Note: As the list scrolls, this function will almost always be called more than once for each individual item in the list's data provider. Your function should not simply return a new accessory every time. This will result in the unnecessary creation and destruction of many icons, which will overwork the garbage collector and hurt performance. It's better to return a new accessory the first time this function is called for a particular item and then return the same accessory if that item is passed to this function again.

An object that stores properties for the accessory label text renderer sub-component (if using accessoryLabelField or accessoryLabelFunction), and the properties will be passed down to the text renderer when this component validates. The available properties depend on which ITextRenderer implementation is returned by accessoryLabelFactory. Refer to feathers.core.ITextRenderer for a list of available text renderer implementations.

If the subcomponent has its own subcomponents, their properties can be set too, using attribute @ notation. For example, to set the skin on the thumb which is in a SimpleScrollBar, which is in a List, you can use the following syntax:

list.verticalScrollBarProperties.@thumbProperties.defaultSkin = new Image(texture);

Setting properties in a accessoryLabelFactory function instead of using accessoryLabelProperties will result in better performance.

In the following example, the accessory label properties are customized:

A function that generates an ImageLoader that uses the result of skinSourceField or skinSourceFunction. Useful for transforming the ImageLoader in some way. For example, you might want to scale the texture for current screen density or apply pixel snapping.

The function is expected to have the following signature:

function():ImageLoader

In the following example, the loader factory is customized:

    renderer.skinLoaderFactory = function():ImageLoader
    {
       var loader:ImageLoader = new ImageLoader();
       loader.scaleFactor = 2;
       return loader;
    };

The default value is function():ImageLoader { return new ImageLoader(); }.

The field in the item that contains a starling.textures.Texture or a URL that points to a bitmap to be used as the item renderer's skin. The renderer will automatically manage and reuse an internal ImageLoader sub-component and this value will be passed to the source property. The ImageLoader may be customized by changing the skinLoaderFactory.

Using a skin source will result in better performance than passing in an ImageLoader or Image through a skinField or skinFunction because the renderer can avoid costly display list manipulation.

All of the skin fields and functions, ordered by priority:

1. skinSourceFunction
2. skinSourceField
3. skinFunction
4. skinField

In the following example, the skin source field is customized:

    renderer.itemHasSkin = true;
    renderer.skinSourceField = "texture";

The default value is "skinSource".

A function used to generate a starling.textures.Texture or a URL that points to a bitmap to be used as the item renderer's skin. The renderer will automatically manage and reuse an internal ImageLoader sub-component and this value will be passed to the source property. The ImageLoader may be customized by changing the skinLoaderFactory.

Using a skin source will result in better performance than passing in an ImageLoader or Image through a skinField or skinnFunction because the renderer can avoid costly display list manipulation.

Note: As the list scrolls, this function will almost always be called more than once for each individual item in the list's data provider. Your function should not simply return a new texture every time. This will result in the unnecessary creation and destruction of many textures, which will overwork the garbage collector and hurt performance. Creating a new texture at all is dangerous, unless you are absolutely sure to dispose it when necessary because neither the list nor its item renderer will dispose of the texture for you. If you are absolutely sure that you are managing the texture memory with proper disposal, it's better to return a new texture the first time this function is called for a particular item and then return the same texture if that item is passed to this function again.

The function is expected to have the following signature:

function( item:Object ):Object

If the item renderer is an IListItemRenderer, the function may optionally have the following signature instead:

function( item:Object, index:int ):Object

If the item renderer is an IGroupedListItemRenderer, the function may optionally have the following signature instead:

function( item:Object, groupIndex:int, itemIndex:int ):Object

The return value is a valid value for the source property of an ImageLoader component.

All of the skin fields and functions, ordered by priority:

1. skinSourceFunction
2. skinSourceField
3. skinFunction
4. skinField

In the following example, the skin source function is customized:

    renderer.itemHasSkin = true;
    renderer.skinSourceFunction = function( item:Object ):Object
    {
       return "http://www.example.com/images/" + item.name + "-skin.png";
    };

The default value is null.

If enabled, calls owner.stopScrolling() when TouchEvents are dispatched by the accessory.

In the following example, the list won't stop scrolling when the accessory is touched:

    renderer.stopScrollingOnAccessoryTouch = false;

The default value is true.

Constructor.

If the component's dimensions have not been set explicitly, it will measure its content and determine an ideal size for itself. If the explicitWidth or explicitHeight member variables are set, those value will be used without additional measurement. If one is set, but not the other, the dimension with the explicit value will not be measured, but the other non-explicit dimension will still need measurement.

Calls saveMeasurements() to set up the actualWidth and actualHeight member variables used for layout.

Meant for internal use, and subclasses may override this function with a custom implementation.

Updates the renderer to display the item's data. Override this function to pass data to sub-components and react to data changes.

Don't forget to handle the case where the data is null.

Gets the accessory to be used by the item renderer when the item renderer's currentState property matches the specified state value.

If a accessory is not defined for a specific state, returns null.

Parameters

Sets the font styles to be used to display the icon label's text when the item renderer's currentState property matches the specified state value.

If font styles are not defined for a specific state, the value of the iconLabelFontStyles property will be used instead.

Note: if the text renderer has been customized with advanced font formatting, it may override the values specified with setIconLabelFontStylesForState() and properties like iconLabelFontStyles and disabledIconLabelFontStyles.

Parameters

See also

An alternate style name to use with the default item renderer to allow a theme to give it a "check" style. If a theme does not provide a style for a check item renderer, the theme will automatically fall back to using the default item renderer style.

An alternate style name should always be added to a component's styleNameList before the component is initialized. If the style name is added later, it will be ignored.

In the following example, the check item renderer style is applied to a list's item renderers:

    list.itemRendererFactory = function():IListItemRenderer
    {
        var itemRenderer:DefaultListItemRenderer = new DefaultListItemRenderer();
        itemRenderer.styleNameList.add( DefaultListItemRenderer.ALTERNATE_STYLE_NAME_CHECK );
        return itemRenderer;
    };

See also

An alternate style name to use with the default item renderer to allow a theme to give it a "drill-down" style. If a theme does not provide a style for a drill-down item renderer, the theme will automatically fall back to using the default item renderer style.

An alternate style name should always be added to a component's styleNameList before the component is initialized. If the style name is added later, it will be ignored.

In the following example, the drill-down style is applied to a list's item renderers:

    list.itemRendererFactory = function():IListItemRenderer
    {
        var itemRenderer:DefaultListItemRenderer = new DefaultListItemRenderer();
        itemRenderer.styleNameList.add( DefaultListItemRenderer.ALTERNATE_STYLE_NAME_DRILL_DOWN );
        return itemRenderer;
    };
