Class | public class StackLayout |
Inheritance | StackLayout BasicLayout LayoutBase OnDemandEventDispatcher Object |
Implements | ISelectable |
Language Version: | ActionScript 3.0 |
Product Version: | Adobe Digital Enterprise Platform Experience Services - Composite Application Framework 10 |
Runtime Versions: | AIR 2.6, Flash Player 10.2 |
StackLayout partially implements ISelectableList
so the layout may be
used as the dataProvider
for a ButtonBar
.
Property | Defined By | ||
---|---|---|---|
clipAndEnableScrolling : Boolean
If true, specifies to clip the children to the boundaries of the viewport. | LayoutBase | ||
constructor : Object
A reference to the class object or constructor function for a given object instance. | Object | ||
dropIndicator : DisplayObject
The DisplayObject that this layout uses for
the drop indicator during a drag-and-drop operation. | LayoutBase | ||
horizontalScrollPosition : Number
The x coordinate of the origin of the viewport in the component's coordinate system,
where the default value is (0,0) corresponding to the upper-left corner of the component. | LayoutBase | ||
layoutTarget : GroupBase [read-only]
The Group for which the layout is working (arranging and sizing its children). | StackLayout | ||
selectedIndex : int
The index of the currently selected element of the group target. | StackLayout | ||
target : GroupBase
The GroupBase container whose elements are measured, sized and positioned
by this layout. | LayoutBase | ||
typicalLayoutElement : ILayoutElement
Used by layouts when fixed row/column sizes are requested but
a specific size isn't specified. | LayoutBase | ||
useVirtualLayout : Boolean
A container can hold any number of children. | LayoutBase | ||
verticalScrollPosition : Number
The y coordinate of the origin of the viewport in the component's coordinate system,
where the default value is (0,0) corresponding to the upper-left corner of the component. | LayoutBase |
Method | Defined By | ||
---|---|---|---|
Constructor
| StackLayout | ||
addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void
Registers an event listener object with an EventDispatcher object so that the listener
receives notification of an event. | OnDemandEventDispatcher | ||
Calculates the drop location in the data provider of the drop target for
the specified dragEvent. | LayoutBase | ||
When useVirtualLayout is true,
this method can be used by the layout target
to clear cached layout information when the target changes. | LayoutBase | ||
Dispatches an event into the event flow. | OnDemandEventDispatcher | ||
[override]
Intercepts the element being added and resizes it to take up the entire space of
the layout. | StackLayout | ||
[override]
Removes the given element from the layout and adjusts the selectedIndex
if the element being removed as the currently selected element. | StackLayout | ||
Returns the specified element's layout bounds as a Rectangle or null
if the index is invalid, the corresponding element is null,
includeInLayout=false,
or if this layout's target property is null. | LayoutBase | ||
Returns the change to the horizontal scroll position to handle
different scrolling options. | LayoutBase | ||
getNavigationDestinationIndex(currentIndex:int, navigationUnit:uint, arrowKeysWrapFocus:Boolean):int
Delegation method that determines which item
to navigate to based on the current item in focus
and user input in terms of NavigationUnit. | LayoutBase | ||
Computes the verticalScrollPosition and
horizontalScrollPosition deltas needed to
scroll the element at the specified index into view. | LayoutBase | ||
Returns the change to the vertical scroll position to handle
different scrolling options. | LayoutBase | ||
Checks whether the EventDispatcher object has any listeners registered for a specific type
of event. | OnDemandEventDispatcher | ||
Indicates whether an object has a specified property defined. | Object | ||
Hides the previously shown drop indicator,
created by the showDropIndicator() method,
removes it from the display list and also stops the drag scrolling. | LayoutBase | ||
Indicates whether an instance of the Object class is in the prototype chain of the object specified
as the parameter. | Object | ||
Measures the target's default size based on its content, and optionally
measures the target's default minimum size. | LayoutBase | ||
Indicates whether the specified property exists and is enumerable. | Object | ||
Removes a listener from the EventDispatcher object. | OnDemandEventDispatcher | ||
Sets the availability of a dynamic property for loop operations. | Object | ||
Sizes, positions and parents the drop indicator based on the specified
drop location. | LayoutBase | ||
Returns the string representation of this object, formatted according to locale-specific conventions. | Object | ||
Returns the string representation of the specified object. | Object | ||
[override]
Adjusts the display to show the currently selected item. | StackLayout | ||
Called by the target at the end of its updateDisplayList
to have the layout update its scrollRect. | LayoutBase | ||
Returns the primitive value of the specified object. | Object | ||
Checks whether an event listener is registered with this EventDispatcher object or any of its ancestors for the specified event type. | OnDemandEventDispatcher |
layoutTarget | property |
layoutTarget:GroupBase
[read-only] Language Version: | ActionScript 3.0 |
Product Version: | Adobe Digital Enterprise Platform Experience Services - Composite Application Framework 10 |
Runtime Versions: | AIR 2.6, Flash Player 10.2 |
The Group for which the layout is working (arranging and sizing its children).
Implementation
public function get layoutTarget():GroupBase
selectedIndex | property |
selectedIndex:int
Language Version: | ActionScript 3.0 |
Product Version: | Adobe Digital Enterprise Platform Experience Services - Composite Application Framework 10 |
Runtime Versions: | AIR 2.6, Flash Player 10.2 |
The index of the currently selected element of the group target.
This property can be used as the source for data binding. When this property is modified, it dispatches the selectedIndexChanged
event.
Implementation
public function get selectedIndex():int
public function set selectedIndex(value:int):void

Language Version: | ActionScript 3.0 |
Product Version: | Adobe Digital Enterprise Platform Experience Services - Composite Application Framework 10 |
Runtime Versions: | AIR 2.6, Flash Player 10.2 |
Intercepts the element being added and resizes it to take up the entire space of the layout. If the index matches the selectedIndex, the element is made visible as well.
