numColumns
which defaults to 3.
Each child's width is changed so that all of the columns maintain the same width. Each
child's height is retained, however, unless the child is less than minRowHeight
.
This pattern means that the columns will be of differing heights. Whenever a new child is added to the end of the target Group's display list, it is added to the shortest column.
When a child is deleted, the children below it in its column are moved upward, the other columns are not affected.
Public Properties
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 | |
![]() | 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 |

Public Methods
Method | Defined By | ||
---|---|---|---|
![]() | 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 | |
![]() |
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 | |
![]() |
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 | |
![]() |
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 | |
![]() |
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 |
Protected Methods
Method | Defined By | ||
---|---|---|---|
![]() |
Calculates how much to scroll for the specified dropLocation
during 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 |
