MosaicLayoutBase component is the base class for most composite application layouts, such as FlowLayout and SmartGridLayout.
Layouts using this base class must support padding, vertical and horizontal gaps, when placing their Group's children.
All layouts derived from MosaicLayoutBase automatically get maximize capability as well as some animation effects (eg, when an item is deleted).
The calculateLayoutPositions() function is the key layout function and should be overridden in every sub-class. This is the function that distinguishes one layout from another.

The DisplayObject that this layout uses for
the drop indicator during a drag-and-drop operation. | LayoutBase | |

a specific size isn't specified. | LayoutBase | |
| useVirtualLayout : Boolean
A container can hold any number of children. | LayoutBase | |

공용 메서드

|---|---|---|---|
| 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 | |
|
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 | |
|
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 | |
|
지정된 속성이 객체에 정의되어 있는지 여부를 나타냅니다. | 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 | |
|
Object 클래스의 인스턴스가 매개 변수로 지정된 객체의 프로토타입 체인에 있는지 여부를 나타냅니다. | Object | |
|
Measures the target's default size based on its content, and optionally
measures the target's default minimum size. | LayoutBase | |
|
지정된 속성이 존재하고 열거 가능한지 여부를 나타냅니다. | Object | |
|
Removes a listener from the EventDispatcher object. | OnDemandEventDispatcher | |
|
루프 작업에서 동적 속성을 사용할 수 있는지 여부를 설정합니다. | Object | |
|
Sizes, positions and parents the drop indicator based on the specified
drop location. | LayoutBase | |
|
로캘별 규칙에 따라 서식이 지정된 이 객체의 문자열 표현을 반환합니다. | Object | |
|
지정된 객체의 문자열 표현을 반환합니다. | 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 | |
|
지정된 객체의 프리미티브 값을 반환합니다. | Object | |
|
Checks whether an event listener is registered with this EventDispatcher object or any of its ancestors for the specified event type. | OnDemandEventDispatcher | |
보호 메서드

|---|---|---|---|
|
Calculates how much to scroll for the specified dropLocation
during a drag and drop gesture. | LayoutBase | |
|
Calculates the bounds for the drop indicator that provides visual feedback
to the user of where the items will be inserted at the end of a drag and drop
gesture. | LayoutBase | |
|
Returns the bounds of the first layout element that either spans or
is above the scrollRect's top edge. | LayoutBase | |
|
Returns the bounds of the first layout element that either spans or
is below the scrollRect's bottom edge. | LayoutBase | |
|
Returns the bounds of the first layout element that either spans or
is to the left of the scrollRect's left edge. | LayoutBase | |
|
Returns the bounds of the first layout element that either spans or
is to the right of the scrollRect's right edge. | LayoutBase | |
|
Returns the bounds of the target's scroll rectangle in layout coordinates. | LayoutBase | |
|
Called when the verticalScrollPosition or
horizontalScrollPosition properties change. | LayoutBase | |
