Implements IScreen

Product Version : Feathers 1.3.0

A screen for use with ScreenNavigator, based on ScrollContainer in order to provide scrolling and layout.

This component is generally not instantiated directly. Instead it is typically used as a super class for concrete implementations of screens. With that in mind, no code example is included here.

The following example provides a basic framework for a new scroll screen:

package
{
    import feathers.controls.ScrollScreen;
    
    public class CustomScreen extends ScrollScreen
    {
        public function CustomScreen()
        {
            super();
        }
        
        override protected function initialize():void
        {
            //runs once when screen is first added to the stage
            //a good place to add children and customize the layout
            
            //don't forget to call this!
            super.initialize()
        }
    }
}

The properties of the event object have the following values:

PropertyValue
