Class | public class ScrollScreen |
Inheritance | ScrollScreen ![]() ![]() ![]() ![]() |
Implements | IScreen |
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 container will auto size itself to fill the entire stage.

INTERACTION_MODE_MOUSE | Constant |
public static const INTERACTION_MODE_MOUSE:String = mouse
The user may only interact with the scroll bars to scroll. The user cannot touch anywhere in the scroller's content and drag like a touch interface.
See also
INTERACTION_MODE_TOUCH | Constant |
public static const INTERACTION_MODE_TOUCH:String = touch
The user may touch anywhere on the scroller and drag to scroll. The scroll bars will be visual indicator of position, but they will not be interactive.
See also
INTERACTION_MODE_TOUCH_AND_SCROLL_BARS | Constant |
public static const INTERACTION_MODE_TOUCH_AND_SCROLL_BARS:String = touchAndScrollBars
The user may touch anywhere on the scroller and drag to scroll, and the scroll bars may be dragged separately. For most touch interfaces, this is not a common behavior. The scroll bar on touch interfaces is often simply a visual indicator and non-interactive.
One case where this mode might be used is a "scroll bar" that
displays a tappable alphabetical index to navigate a
GroupedList
with alphabetical categories.

SCROLL_BAR_DISPLAY_MODE_FIXED | Constant |
public static const SCROLL_BAR_DISPLAY_MODE_FIXED:String = fixed
The scroll bars are always visible and appear next to the scroller's view port, making the view port smaller than the scroller.
See also
SCROLL_BAR_DISPLAY_MODE_FLOAT | Constant |
public static const SCROLL_BAR_DISPLAY_MODE_FLOAT:String = float
The scroll bars appear above the scroller's view port, overlapping the content, and they fade out when not in use.
See also
SCROLL_BAR_DISPLAY_MODE_NONE | Constant |
public static const SCROLL_BAR_DISPLAY_MODE_NONE:String = none
The scroll bars are never visible.
See also
SCROLL_POLICY_AUTO | Constant |
public static const SCROLL_POLICY_AUTO:String = auto
The scroller may scroll if the view port is larger than the scroller's bounds. If the interaction mode is touch, the elastic edges will only be active if the maximum scroll position is greater than zero. If the scroll bar display mode is fixed, the scroll bar will only be visible when the maximum scroll position is greater than zero.
See also
SCROLL_POLICY_OFF | Constant |
public static const SCROLL_POLICY_OFF:String = off
The scroller does not scroll at all. If the scroll bar display mode is fixed or float, the scroll bar will never be visible.
See also
SCROLL_POLICY_ON | Constant |
public static const SCROLL_POLICY_ON:String = on
The scroller will always scroll. If the interaction mode is touch, elastic edges will always be active, even when the maximum scroll position is zero. If the scroll bar display mode is fixed, the scroll bar will always be visible.

VERTICAL_SCROLL_BAR_POSITION_LEFT | Constant |
public static const VERTICAL_SCROLL_BAR_POSITION_LEFT:String = left
The vertical scroll bar will be positioned on the left.
