The field in the item that contains a display object to be positioned in the content position of the renderer. If you wish to display a texture in the content position, it's better for performance to use contentSourceField instead.

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

1. contentSourceFunction
2. contentSourceField
3. contentLabelFunction
4. contentLabelField
5. contentFunction
6. contentField

In the following example, the content field is customized:

    renderer.contentField = "header";

The default value is "content".

       return content;
    };

A function that generates an ITextRenderer that uses the result of contentLabelField or contentLabelFunction. Can be used to set properties on the ITextRenderer.

In the following example, a custom content label factory is passed to the renderer:

    renderer.contentLabelFactory = function():ITextRenderer
    {
        var renderer:TextFieldTextRenderer = new TextFieldTextRenderer();
        renderer.textFormat = new TextFormat( "Source Sans Pro", 16, 0x333333 );
        renderer.embedFonts = true;
        return renderer;
    };

The default value is null.

The field in the item that contains a string to be displayed in a renderer-managed Label in the content position of the renderer. The renderer will automatically reuse an internal Label and swap the text when the data changes. This Label may be skinned by changing the contentLabelFactory.

Using an content label will result in better performance than passing in a Label through a contentField or contentFunction because the renderer can avoid costly display list manipulation.

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

1. contentTextureFunction
2. contentTextureField
3. contentLabelFunction

    renderer.contentLabelField = "text";

The default value is "label".

    };

The default value is null.

An object that stores properties for the content label text renderer sub-component, 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 contentLabelFactory. 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);

In the following example, a custom content label properties are customized:

    renderer.contentLabelProperties.textFormat = new TextFormat( "Source Sans Pro", 16, 0x333333 );
    renderer.contentLabelProperties.embedFonts = true;

The default value is null.

See also

The value added to the styleNameList of the content label text renderer. This variable is protected so that sub-classes can customize the label text renderer style name in their constructors instead of using the default style name defined by DEFAULT_CHILD_STYLE_NAME_CONTENT_LABEL.

To customize the content label text renderer style name without subclassing, see customContentLabelStyleName.

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

In the following example, a custom content loader factory is passed to the renderer:

    renderer.contentLoaderFactory = 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 data that contains a starling.textures.Texture or a URL that points to a bitmap to be used as the renderer's content. 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 contentLoaderFactory.

Using an content source will result in better performance than passing in an ImageLoader or Image through contentField or contentFunction because the renderer can avoid costly display list manipulation.

    renderer.contentSourceField = "texture";

The default value is "source".

Using an content source will result in better performance than passing in an ImageLoader or Image through contentField or contentFunction because the renderer can avoid costly display list manipulation.

       return "http://www.example.com/thumbs/" + item.name + "-thumb.png";
    };

The default value is null.

Data for a footer renderer from the grouped list's data provider. A footer renderer should be designed with the assumption that its data will change as the list scrolls.

This property is set automatically by the list, and it should not be set manually.

The ID of the factory used to create this footer renderer.

This property is set by the list, and should not be set manually.

The default IStyleProvider for all DefaultGroupedListHeaderOrFooterRenderer components.

The default value is null.

The index of the group within the data provider of the grouped list.

This property is set automatically by the list, and it should not be set manually.

The index of this display object within the layout.

This property is set automatically by the list, and it should not be set manually.

The number of text lines displayed by the renderer. The component may contain multiple text lines if the text contains line breaks or if the wordWrap property is enabled.

See also

The grouped list that contains this footer renderer.

This property is set automatically by the list, and it should not be set manually.

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.

Uses the content fields and functions to generate content for a specific group header or footer.

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

1. contentTextureFunction
2. contentTextureField
3. contentLabelFunction
4. contentLabelField
5. contentFunction
6. contentField

Parameters

The default value added to the styleNameList of the content label.
