column | proprietà |
public var column:AdvancedDataGridColumn| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
The id of the column for which the renderer is used.
If you omit this property,
you can use the columnIndex property to specify the column.
columnIndex | proprietà |
public var columnIndex:int = -1| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
The column index for which the renderer is used, where the first column is at an index of 0.
Il valore predefinito è -1.
columnSpan | proprietà |
public var columnSpan:int = 1| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
Specifies how many columns the renderer should span. Set this property to 0 to span all columns. The AdvancedDataGrid control uses this information to set the width of the item renderer.
Il valore predefinito è 1.
dataField | proprietà |
public var dataField:String| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
The data field in the data provider for the renderer. This property is optional.
depth | proprietà |
public var depth:int = -1| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
Depth in the tree at which the renderer is used, where the top-most node of the tree is at a depth of 1. Use this property if the renderer should only be used when the tree is expanded to a certain depth, but not for all nodes in the tree. By default, the control uses the renderer for all levels of the tree.
renderer | proprietà |
public var renderer:IFactory| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
The ItemRenderer IFactory used to create an instance of the item renderer.
rowSpan | proprietà |
public var rowSpan:int = 1| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
Specifies how many rows the renderer should span. The AdvancedDataGrid control uses this information to set the height of the renderer.
Currently, this property is not implemented in the AdvancedDataGrid control.
Il valore predefinito è 1.
AdvancedDataGridRendererProvider | () | Funzione di costruzione |
public function AdvancedDataGridRendererProvider()| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
