public function GridSortEvent(type:String, bubbles:Boolean, cancelable:Boolean, columnIndices:Vector.<int>, oldSortFields:Array, newSortFields:Array)| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4.5 |
| Versioni runtime: | Flash Player 10, AIR 2.5 |
Constructor.
Parametritype:String — The event type; indicates the action that caused the event.
| |
bubbles:Boolean — Specifies whether the event can bubble
up the display list hierarchy.
| |
cancelable:Boolean — Specifies whether the behavior
associated with the event can be prevented.
| |
columnIndices:Vector.<int> — The vector of column indices of the sorted columns.
| |
oldSortFields:Array — The array of ISortFields for the last sort.
| |

SORT_CHANGE | Costante |
public static const SORT_CHANGE:String = "sortChange"| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4.5 |
| Versioni runtime: | Flash Player 10, AIR 2.5 |
The GridSortEvent.SORT_CHANGE constant defines
the value of the type property of the event object for a
sortChange event, which indicates that a sort filter has just been
applied to the grid's dataProvider collection.
Typically, if a column header mouse click triggered the sort, then the last index of
columnIndices is the column's index.
Note that interactive sorts are not necessarily triggered by a mouse click.
This event is dispatched when the user interacts with the control.
When you sort the data provider's collection programmatically,
the component does not dispatch the sortChange event.
The properties of the event object have the following values:
| Property | Value |
|---|---|
bubbles | false |
cancelable | false |
columnIndices | The vector of column indices of the sorted columns. |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myDataGrid.addEventListener() to register an event listener,
myDataGrid is the value of the currentTarget. |
newSortFields | The array of ISortFields for this sort. |
oldSortFields | The array of ISortFields for the last sort. |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |
type | GridSelectionEvent.SORT_CHANGE |

SORT_CHANGING | Costante |
public static const SORT_CHANGING:String = "sortChanging"| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4.5 |
| Versioni runtime: | Flash Player 10, AIR 2.5 |
The GridSortEvent.SORT_CHANGING constant defines
the value of the type property of the event object for a
sortChanging event, which indicates that a sort filter is about to be
applied to the grid's dataProvider collection.
Call preventDefault() on this event to prevent the sort from occurring
or you modify columnIndices and newSortFields if you want to
change the default behavior of the sort.
Typically, if a column header mouse click triggered the sort, then the last index of
columnIndices is the column's index.
Note that interactive sorts are not necessarily triggered by a mouse click.
This event is dispatched when the user interacts with the control.
When you sort the data provider's collection programmatically,
the component does not dispatch the sortChanging event.
The properties of the event object have the following values:
| Property | Value |
|---|---|
bubbles | false |
cancelable | false |
columnIndices | The vector of column indices of the columns to be sorted. |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myDataGrid.addEventListener() to register an event listener,
myDataGrid is the value of the currentTarget. |
newSortFields | The array of ISortFields for this sort. |
oldSortFields | The array of ISortFields for the last sort. |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |
