| Method | Defined By | ||
|---|---|---|---|
MobileGridLayout(grid:MobileGrid) | MobileGridLayout | ||
 | addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void | OnDemandEventDispatcher | |
|
Calculates the drop location in the data provider of the drop target for
the specified dragEvent. | LayoutBase | |
| clearVirtualLayoutCache():void
When useVirtualLayout is true,
this method can be used by the layout target
to clear cached layout information when the target changes. | LayoutBase | |
| dispatchEvent(event:Event):Boolean | OnDemandEventDispatcher | |
| elementAdded(index:int):void
Called by the target after a layout element
has been added and before the target's size and display list are
validated. | LayoutBase | |
| elementRemoved(index:int):void
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 | |
| fractionOfElementInView(index:int):Number
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 | |
| getElementBounds(index:int):Rectangle
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 | |
| getHorizontalScrollPositionDelta(navigationUnit:uint):Number
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 | |
| getScrollPositionDeltaToElement(index:int):Point
Computes the verticalScrollPosition and
horizontalScrollPosition deltas needed to
scroll the element at the specified index into view. | LayoutBase | |
| getVerticalScrollPositionDelta(navigationUnit:uint):Number
Returns the change to the vertical scroll position to handle
different scrolling options. | LayoutBase | |
| hasEventListener(type:String):Boolean | OnDemandEventDispatcher | |
| hideDropIndicator():void
Hides the previously shown drop indicator,
created by the showDropIndicator() method,
removes it from the display list and also stops the drag scrolling. | LayoutBase | |
| measure():void
Measures the target's default size based on its content, and optionally
measures the target's default minimum size. | LayoutBase | |
| removeEventListener(type:String, listener:Function, useCapture:Boolean = false):void | OnDemandEventDispatcher | |
| showDropIndicator(dropLocation:DropLocation):void
Sizes, positions and parents the drop indicator based on the specified
drop location. | LayoutBase | |
updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void [override] | MobileGridLayout | ||
| updateScrollRect(w:Number, h:Number):void
Called by the target at the end of its updateDisplayList
to have the layout update its scrollRect. | LayoutBase | |
| willTrigger(type:String):Boolean | OnDemandEventDispatcher | |
| Method | Defined By | ||
|---|---|---|---|
| calculateDragScrollDelta(dropLocation:DropLocation, elapsedTime:Number):Point
Calculates how much to scroll for the specified dropLocation
during a drag and drop gesture. | LayoutBase | |
| calculateDropIndex(x:Number, y:Number):int
Returns the index where a new item should be inserted if
the user releases the mouse at the specified coordinates
while completing a drag and drop gesture. | LayoutBase | |
| calculateDropIndicatorBounds(dropLocation:DropLocation):Rectangle
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 | |
| getElementBoundsAboveScrollRect(scrollRect:Rectangle):Rectangle
Returns the bounds of the first layout element that either spans or
is above the scrollRect's top edge. | LayoutBase | |
| getElementBoundsBelowScrollRect(scrollRect:Rectangle):Rectangle
Returns the bounds of the first layout element that either spans or
is below the scrollRect's bottom edge. | LayoutBase | |
| getElementBoundsLeftOfScrollRect(scrollRect:Rectangle):Rectangle
Returns the bounds of the first layout element that either spans or
is to the left of the scrollRect's left edge. | LayoutBase | |
| getElementBoundsRightOfScrollRect(scrollRect:Rectangle):Rectangle
Returns the bounds of the first layout element that either spans or
is to the right of the scrollRect's right edge. | LayoutBase | |
| getScrollRect():Rectangle
Returns the bounds of the target's scroll rectangle in layout coordinates. | LayoutBase | |
| scrollPositionChanged():void
Called when the verticalScrollPosition or
horizontalScrollPosition properties change. | LayoutBase | |
updateColumnWidths(unscaledWidth:Number):void compute colum actual widths from colum width and percentWidth
simple algorithm is following:
first set all columns that have fixed width
set distribute the remainder between the percentages, normalized to 100%
