參數

	`type:String` — The event type; indicates the action that caused the event.

	`bubbles:Boolean` (default = `false`) — Specifies whether the event can bubble up the display list hierarchy.

	`cancelable:Boolean` (default = `false`) — Specifies whether the behavior associated with the event can be prevented.

	`kind:String` (default = `null`) — The kind of changing event. The valid values are defined in `GridSelectionEventKind` class as constants. This value determines which properties in the event are used.

	`selectionChange:CellRegion` (default = `null`) — The proposed or accepted change to the current selection. Use the Spark DataGrid selection methods to determine the current selection.

常數詳細資訊

SELECTION_CHANGE

常數

public static const SELECTION_CHANGE:String = "selectionChange"

語言版本:

ActionScript 3.0

產品版本:

Flex 4.5

執行階段版本:

Flash Player 10, AIR 2.5

The GridSelectionEvent.SELECTION_CHANGE constant defines the value of the type property of the event object for a selectionChange event, which indicates that the current selection has just been changed.

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 selectionChange event.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	false
`currentTarget`	The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
kind	The kind of changing event. The valid values are defined in GridSelectionEventKind class as constants. This value determines which properties in the event are used.
`selectionChange`	The just completed selection change that was triggered by a user gesture. Use the DataGrid selection methods to determine the current selection.
`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.SELECTION_CHANGE

SELECTION_CHANGING

常數

public static const SELECTION_CHANGING:String = "selectionChanging"

語言版本:

ActionScript 3.0

產品版本:

Flex 4.5

執行階段版本:

Flash Player 10, AIR 2.5

The GridSelectionEvent.SELECTION_CHANGING constant defines the value of the type property of the event object for a selectionChanging event, which indicates that the current selection is about to change. Call preventDefault() on this event to prevent the selection from changing.

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 selectionChanging event.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	false
`currentTarget`	The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
kind	The kind of changing event. The valid values are defined in GridSelectionEventKind class as constants. This value determines which properties in the event are used.
`selectionChange`	The upcoming selection change that is triggered by a user gesture.
`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.SELECTION_CHANGING
