Constructor. | FormLayout | ||
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 1.0 if the specified index is completely in view, 0.0 if
it's not, or a value between 0.0 and 1.0 that represents the percentage
of the if the index that is partially in view. | VerticalLayout | ||
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 | ||
Geeft aan of voor een object een opgegeven eigenschap is gedefinieerd. | Object | ||
Hides the previously shown drop indicator,

removes it from the display list and also stops the drag scrolling. | LayoutBase | ||
Geeft aan of een instantie van de klasse Object zich in de prototypeketen van het object bevindt dat als parameter is opgegeven. | Object | ||
Measures the target's default size based on its content, and optionally
measures the target's default minimum size. | LayoutBase | ||
Geeft aan of de opgegeven eigenschap bestaat en kan worden opgesomd. | Object | ||
Removes a listener from the EventDispatcher object. | OnDemandEventDispatcher | ||
Stelt de beschikbaarheid van een dynamische eigenschap voor lusbewerkingen in. | Object | ||
Sizes, positions and parents the drop indicator based on the specified
drop location. | LayoutBase | ||
Geeft de tekenreeksweergave van dit object weer, geformatteerd volgens de locatiespecifieke conventies. | Object | ||
Retourneert een tekenreeksrepresentatie van het opgegeven object. | 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 | ||
