direction | property |
direction:String
[read-write]
The direction in which this control lays out its children.
Possible values are TileBaseDirection.HORIZONTAL
and TileBaseDirection.VERTICAL
.
The default value is TileBaseDirection.HORIZONTAL
.
If the value is TileBaseDirection.HORIZONTAL
, the tiles are
laid out along the first row until the number of visible columns or maxColumns
is reached and then a new row is started. If more rows are created
than can be displayed at once, the control will display a vertical scrollbar.
The opposite is true if the value is TileBaseDirection.VERTICAL
.
This property can be used as the source for data binding.
Implementation public function get direction():String
public function set direction(value:String):void
maxColumns | property |
maxColumns:int
[read-write]
The maximum number of columns that the control can have.
If 0, then there are no limits to the number of
columns. This value is ignored
if the direction is TileBaseDirection.VERTICAL
because the control will have as many columns as it needs to
to display all the data.
The default value is 0 (no limit).
Implementation public function get maxColumns():int
public function set maxColumns(value:int):void
maxRows | property |
maxRows:int
[read-write]
The maximum number of rows that the control can have.
If 0, then there is no limit to the number of
rows. This value is ignored
if the direction is TileBaseDirection.HORIZONTAL
because the control will have as many rows as it needs to
to display all the data.
The default value is 0 (no limit).
Implementation public function get maxRows():int
public function set maxRows(value:int):void
measuringObjects | property |
protected var measuringObjects:Dictionary

unscaledHeight:Number (default = -1 ) — The height of the listContent before any external scaling is applied.
|
createItemRenderer | () | method |
public override function createItemRenderer(data:Object):IListItemRenderer
Get the appropriate renderer, using the default renderer if none is specified.

|
drawTileBackground | () | method |
protected function drawTileBackground(s:Sprite, rowIndex:int, columnIndex:int, width:Number, height:Number, color:uint, item:IListItemRenderer):DisplayObject
Draws the background for an individual tile. Takes a Sprite object, applies the background dimensions and color, and returns the sprite with the values applied.
Parameterss:Sprite — The Sprite that contains the individual tile backgrounds.
|
|
rowIndex:int — The index of the row that contains the tile.
|
|
columnIndex:int — The index of the column that contains the tile.
|
|
width:Number — The width of the background.

Draws the backgrounds, if any, behind all of the tiles.
This implementation makes a Sprite names "tileBGs" if
it doesn't exist, adds it to the back
of the z-order in the listContent
, and
calls drawTileBackground()
for each visible
tile.
makeListData | () | method |
protected function makeListData(data:Object, uid:String, rowNum:int, columnNum:int):BaseListData
Creates a new ListData instance and populates the fields based on the input data provider item.
Parametersdata:Object — The data provider item used to populate the ListData.
|
|
uid:String — The UID for the item.
|
|
rowNum:int — The index of the item in the data provider.
|
|
columnNum:int — The columnIndex associated with this item.

A newly constructed ListData object.
|
scrollHorizontally | () | method |
protected override function scrollHorizontally(pos:int, deltaPos:int, scrollUp:Boolean):void
Adjusts the renderers in response to a change in scroll position.
The list classes attempt to optimize scrolling
when the scroll position has changed by less than
the number of visible rows. In that situation
some rows are unchanged and just need to be moved,
other rows are removed and then new rows are added.
If the scroll position changes too much, all old rows are removed
and new rows are added by calling the makeRowsAndColumns()
method for the entire viewable area.
Not implemented in ListBase because the default list is single column and therefore doesn't scroll horizontally.
Parameterspos:int — The new scroll position.
|
|
deltaPos:int — The change in position. This value is always a positive number.
|
|
scrollUp:Boolean — true if scroll position is getting smaller.
|
