public class DragManager
继承DragManager Inheritance Object

语言版本: ActionScript 3.0
产品版本: Flex 3
运行时版本: Flash Player 9, AIR 1.1

DragManager 类管理拖放操作,您可以使用它来将数据从 Flex 应用程序中的一个位置移动到另一位置。例如,您可以选择一个对象(如 List 控件中的项目)或一个 Flex 控件(如 Image 控件),然后将其拖至另一个组件进行添加。

DragManager 的所有方法和属性都是静态的,因此不需要为其创建实例。

所有 Flex 组件都支持拖放操作。Flex 为 List、Tree 和 DataGrid 控件的拖放操作提供了附加支持。

当用户使用鼠标选择某个项目时,所选组件称为拖动启动器。拖动操作期间显示的图像称为拖动代理。

当用户将拖动代理移动到其他组件时,系统会向该组件发送 dragEnter 事件。如果该组件接受拖动,即可成为放置目标,并接收 dragOverdragExitdragDrop 事件。

拖动操作完成后,会向拖动启动器发送 dragComplete 事件。

方法详细信息

acceptDragDrop

()方法
public static function acceptDragDrop(target:IUIComponent):void

语言版本: ActionScript 3.0
产品版本: Flex 3
运行时版本: Flash Player 9, AIR 1.1

如果接受拖/放数据,将从 dragEnter 事件处理函数调用此方法。通常,您将 event.target 强制类型转换为放置目标的数据类型。在以下示例中,放置目标为 MX Canvas 容器:

DragManager.acceptDragDrop(Canvas(event.target));

参数

target:IUIComponent — 接受拖动的放置目标。

doDrag

()方法 
public static function doDrag(dragInitiator:IUIComponent, dragSource:DragSource, mouseEvent:MouseEvent, dragImage:IFlexDisplayObject = null, xOffset:Number = 0, yOffset:Number = 0, imageAlpha:Number = 0.5, allowMove:Boolean = true):void

语言版本: ActionScript 3.0
产品版本: Flex 3
运行时版本: Flash Player 9, AIR 1.1

启动拖放操作。

参数

dragInitiator:IUIComponent — 指定启动拖动的组件的 IUIComponent。
 
dragSource:DragSource — 包含正在拖动的数据的 DragSource 对象。
 
mouseEvent:MouseEvent — 包含与启动拖动相关的鼠标信息的 MouseEvent。
 
dragImage:IFlexDisplayObject (default = null) — 要拖动的图像。此参数是可选的。如果省略此参数,则在拖放操作期间将使用标准的拖动矩形。如果指定了某个图像,则必须显式设置该图像的高度和宽度,否则此图像将不显示。
 
xOffset:Number (default = 0) — 用于指定 dragImage 的 x 偏移(以像素为单位)的数字。此参数是可选的。如果省略此参数,将在拖动启动器的左上角显示拖动代理。该偏移是指从拖动代理的左边缘到拖动启动器的左边缘的距离(以像素为单位),通常为负数。
 
yOffset:Number (default = 0) — 用于指定 dragImage 的 y 偏移(以像素为单位)的数字。此参数是可选的。如果省略此参数,将在拖动启动器的左上角显示拖动代理。该偏移是指从拖动代理的上边缘到拖动启动器的上边缘的距离(以像素为单位),通常为负数。
 
imageAlpha:Number (default = 0.5) — 用于指定拖动图像所用的 Alpha 值的数字。此参数是可选的。如果省略此参数,则默认的 Alpha 值为 0.5。值为 0.0 表示图像是透明的;值为 1.0 表示图像完全不透明。
 
allowMove:Boolean (default = true) — 指示是否允许放置目标移动所拖动的数据。
