for a ButtonBar
.
Egenskap | Definieras med | ||
---|---|---|---|
clipAndEnableScrolling : Boolean
If true, specifies to clip the children to the boundaries of the viewport. | LayoutBase | ||
constructor : Object
En referens till klassobjektet eller konstruktorfunktionen för en given objektinstans. | 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 [skrivskyddad]
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,

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 | ||
[åsidosätt]
Intercepts the element being added and resizes it to take up the entire space of
the layout. | StackLayout | ||
[åsidosätt]
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 | ||
Anger om det finns en egenskap angiven för ett objekt. | 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 | ||
Anger om en instans av klassen Object finns i prototypkedjan för objektet som anges som parameter. | Object | ||
Measures the target's default size based on its content, and optionally
measures the target's default minimum size. | LayoutBase | ||
Anger om den angivna egenskapen finns och är uppräkningsbar. | Object | ||
Removes a listener from the EventDispatcher object. | OnDemandEventDispatcher | ||
Anger tillgänglighet för en dynamisk egenskap för slingåtgärder. | Object | ||
Sizes, positions and parents the drop indicator based on the specified
drop location. | LayoutBase | ||
Returnerar det här objektets strängrepresentation, formaterad i enlighet med språkspecifika konventioner. | Object | ||
Returnerar det angivna objektets strängbeteckning. | Object | ||
[åsidosätt]
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 | ||
Returnerar det angivna objektets primitiva värde. | Object | ||
Checks whether an event listener is registered with this EventDispatcher object or any of its ancestors for the specified event type. | OnDemandEventDispatcher |
