List Item Base Widgets

Most of the list item widgets follow similar UI traits. To provide ease of implementation and uniform behavior, a set of abstract classes is used to build the list item widgets. These are classified as list item base widgets.

List Item Title Widget

This widget defines the UI elements that each list item should have.

The UI elements can be customized to match the style of the user's application. The customizations can be done programmatically using the APIs.

APIs

List of the customization APIs

• UIFont *titleFont; - The font/size to use for the title.

• UIColor *iconTintColor; - The tint color applied to the icon.
• UIColor *backgroundColor; - The background color for the widget.
