The layout attempts to size all children to their preferred size. If there is enough space, each child is set to its preferred size, plus any excess space evenly distributed among the children.
If there is not enough space for all the children to be sized to their preferred size, then the children that are smaller than the average width are allocated their preferred size and the rest of the elements are reduced equally.
All children are set to the height of the parent.

Constructor. | ButtonBarHorizontalLayout | ||
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 | ||
Called by the target after a layout element
has been added and before the target's size and display list are
validated. | LayoutBase | ||
This method must is called by the target after a layout element
has been removed and before the target's size and display list are
validated. | LayoutBase | ||
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 | ||
Indica si un objeto tiene definida una propiedad especificada. | 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 | ||
Indica si hay una instancia de la clase Object en la cadena de prototipo del objeto especificado como parámetro. | Object | ||
Measures the target's default size based on its content, and optionally
measures the target's default minimum size. | LayoutBase | ||
Indica si existe la propiedad especificada y si es enumerable. | Object | ||
Removes a listener from the EventDispatcher object. | OnDemandEventDispatcher | ||
Establece la disponibilidad de una propiedad dinámica para operaciones de bucle. | Object | ||
Sizes, positions and parents the drop indicator based on the specified
drop location. | LayoutBase | ||
Devuelve la representación de cadena de este objeto, con formato según las convenciones específicas de configuración regional. | Object | ||
Devuelve la representación de cadena del objeto especificado. | Object | ||
Sizes and positions the target's elements. | LayoutBase | ||
Called by the target at the end of its updateDisplayList
to have the layout update its scrollRect. | LayoutBase | ||
Devuelve el valor simple del objeto especificado. | Object | ||
Checks whether an event listener is registered with this EventDispatcher object or any of its ancestors for the specified event type. | OnDemandEventDispatcher |
gap | propiedad |

The horizontal space between layout elements. Note that the gap is only applied between layout elements, so if there's just one element, the gap has no effect on the layout.
El valor predeterminado es 0.
