The SmartGridLayout is different: it tries to maximimze the space in order to present as much
of the child components as possible. If there is only one child, that child takes up 100% of the
space, filling the area of the target Group. If there are two children, the SmartGrid divides the
space in half, but gives each child 100% of the height. The children are separated into columns
up to the maxNumColumns number of columns is reached.
Once the first row is filled out, the space is divided evenly amoung the children, shrinking
the children in height, but maintaining the maxNumColumns number of columns. Once
the child-height reaches minRowHeight the children stop shrinking and continue to
fill the space vertically. If the target Group is contained within a Scroller, scrollbars should
appear.

| 產品版本: | Adobe Digital Enterprise Platform Experience Services - Composite Application Framework 10 |
| 執行階段版本: | AIR 2.6, Flash Player 10.2 |
Determines the size and position of the drop indicator, returning an Rectangle with the proper boundaries. The dropLocation always points to the item being moved, so the indicator is almost always drawn to its left (column orientation) or top (row orientation). If the location points to the last item (the index is equal to the number of items in the target), then the indicator is drawn to its right (column) or bottom (row).
參數
dropLocation:DropLocation — The position within the layout where the drop can be expected.
|
Rectangle — A rectangle the describes the area of the drop.

Determines the location of the drop (should it happen) and returns that information in the form of a DropLocation. However, since this layout is row,column based and index may not be meaningful, the object returned is an instance of MosaicDropLocation that contains row and column index information.
參數
dragEvent:DragEvent — The event that contains the position of the mouse.
|
DropLocation — The location where the drop could happen.

參數
width:Number — The width of the target Group's area.
| |
height:Number — The height of the target Group's area.
| |
updateInPlace:Boolean — If true, the children are changed, if false, they are left as-is.
| |
returnArray:Boolean — If true, an array of row and column positions is returned.
