Method Detail
adjustRow | () | method |
protected function adjustRow(contentHolder:ListBaseContentHolder, rowNum:int, yy:Number, hh:Number):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Adjusts the size and positions of the renderers for the given rowNum, row position and height.
Parameters
contentHolder:ListBaseContentHolder — The set of rows (locked rows, regular rows).
| |
rowNum:int — The row number.
| |
yy:Number — The y position of the row.
| |
hh:Number — The height of the row.

calculateRowHeight | () | method |
protected function calculateRowHeight(data:Object, hh:Number, skipVisible:Boolean = false):Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Calculates the row height of columns in a row.
If skipVisible is true>,
the DataGridBase already knows the height of
the renderers for the column that do fit in the display area
so this method only needs to calculate for the item renderers
that would exist if other columns in that row were in the
display area. This is needed so that if the user scrolls
horizontally, the height of the row does not adjust as different
columns appear and disappear.
Parameters
data:Object — The data provider item for the row.
| |
hh:Number — The current height of the row.
| |
skipVisible:Boolean (default = false)true, there is no need to measure item
renderers in visible columns.
|
Number — The row height, in pixels.
|

Removes renderers from a row that should be empty for the given rowNum.
Parameters
contentHolder:ListBaseContentHolder — The set of rows (locked rows, regular rows).
| |
rowNum:int — The row number.
|

| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Returns the item renderer for a column cell or for a column header. This method returns the default item renderer if no custom render is assigned to the column.
This method is public so that is can be accessed by the DataGridHeader class, and is primarily used in subclasses of the DataGrid control.
Parameters
c:DataGridColumn — The DataGridColumn instance of the item renderer.
| |
forHeader:Boolean — true to return the header item renderer,
and false to return the item render for the column cells.
| |
data:Object — If forHeader is false,
the data Object for the item renderer.
If forHeader is true,
the DataGridColumn instance.
|
IListItemRenderer — The item renderer.
|

| Runtime Versions: | Flash Player 9, AIR 1.1 |
Draws an item if it is visible.
Parameters
uid:String — The uid used to find the renderer.
| |
selected:Boolean (default = false)true if the renderer should be drawn in
its selected state.
| |
highlighted:Boolean (default = false)true if the renderer should be drawn in
its highlighted state.
| |
caret:Boolean (default = false)true if the renderer should be drawn as if
it is the selection caret.

via an effect.
|
finishKeySelection | () | method |

| Runtime Versions: | Flash Player 9, AIR 1.1 |
Sets selected items based on the caretIndex and
anchorIndex properties.
This method is called by the keyboard selection handlers
and by the updateDisplayList() method in case the
keyboard selection handler received a page fault while scrolling to get more items.
itemRendererToIndices | () | method |
override protected function itemRendererToIndices(item:IListItemRenderer):Point| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Returns a Point object that defines the columnIndex and rowIndex properties of an
item renderer. Because item renderers are only created for items
within the set of viewable rows, you cannot use this method to get the indices for items
that are not visible. Also, item renderers
are recycled so the indices that you get for an item might change
if that item renderer is reused to display a different item.
Usually, this method is called during mouse and keyboard handling
when the set of data displayed by the item renderers has not yet changed.
Parameters
item:IListItemRenderer — An item renderer.
|
Point — A Point object. The x property is the columnIndex
and the y property is the rowIndex.
|
layoutColumnItemRenderer | () | method |

| Runtime Versions: | Flash Player 9, AIR 1.1 |
Sizes and temporarily positions an itemRenderer for a column, returning its size as a Point. The final position might be adjusted later due to alignment settings.
Parameters
c:DataGridColumn — The DataGridColumn for the renderer.
| |
item:IListItemRenderer — The renderer.
| |
xx:Number — The x position.
| |
yy:Number — The y position.
|
Point — Size of the renderer as a Point.
