public final class Mouse
继承Mouse Inheritance Object

语言版本: ActionScript 3.0
运行时版本: AIR 1.0, Flash Player 9

Mouse 类的方法用于隐藏和显示鼠标指针,或将指针设置为特定样式。Mouse 类是不通过构造函数即可访问其属性和方法的顶级类。默认情况下,指针是可见的,但可以将其隐藏并实现自定义指针。

属性详细信息

cursor

属性
cursor:String

语言版本: ActionScript 3.0
运行时版本: Flash Player 10.2, AIR 1.5

本机光标的名称。



实现
    public static function get cursor():String
    public static function set cursor(value:String):void

supportsCursor

属性 
supportsCursor:Boolean  [只读]

语言版本: ActionScript 3.0
运行时版本: Flash Player 10.1, AIR 2

表示计算机或设备是否显示永久光标。

在大多数桌面计算机上 supportsCursor 属性为 true,而在大多数移动设备上为 false

注意:不管该属性是否为 true 都可调度鼠标事件。但是,鼠标事件的行为可能不同,具体取决于指针设备的物理特性。



实现
    public static function get supportsCursor():Boolean

相关 API 元素


示例  ( 如何使用本示例 )
以下示例是一个简单测试,用于指示当前是否支持永久光标。测试该示例时,单击文本字段可查看属性值:
import flash.events.*;
import flash.display.*;
import flash.ui.Mouse;
import flash.text.TextField;

var supportsCursorTxt:TextField = new TextField();
supportsCursorTxt.width = 200;
supportsCursorTxt.border = true;
addChild(supportsCursorTxt);

addEventListener (MouseEvent.CLICK, getScreenKeyboardType);

function getScreenKeyboardType(e:MouseEvent):void{
    supportsCursorTxt.text= "Supports Cursor is : " + String(flash.ui.Mouse.supportsCursor);

}
下面的示例对不同的用户输入环境进行测试并做出响应。此示例假设它是与使用光标的游戏对应的代码的一部分。首先,此示例测试该环境是否支持使用光标。如果不支持,则测试该环境是否支持与笔针交互。如果支持,则插入代码来自定义游戏以使用笔针。如果此环境支持手指交互,则插入代码来自定义程序以满足特定的手指触摸需求。如果没有任何受支持的指针设备,则开发人员需要创建替代光标或某种交互方式,例如,按键。
if(Mouse.supportsCursor) {
    //Game acts as before
} else {
    if(Capabilities.touchscreenType == TouchscreenType.STYLUS ){
        //The Game has to change so that the character is chasing the location of the stylus as 
        //it's dragged around. Some of the animations will have to change
    }else if(Capabilities.touchscreenType = TouchscreenType.FINGER){
        //Same as above, except that the hit-area is larger for a finger.
    }else{
        //There's no pointing device at all. The developer designs some sort of custom cursor to 
        //be controlled with key presses or similar input
    }
}

supportsNativeCursor

属性 
supportsNativeCursor:Boolean  [只读]

语言版本: ActionScript 3.0
运行时版本: Flash Player 10.2, AIR 1.5

MouseExample.as

下例使用 MouseExample、SimpleButton、ButtonDisplayState 和 CustomCursor 类将一个简单的按钮放在舞台上。按钮具有自定义指针,并且在单击按钮时该按钮将会发生变化。这是由以下步骤完成的:
  1. 声明下列实例属性:CustomCursor 类型的 cursor、CustomButton 类型的 child 和 uint 类型的 gutter
  2. child 赋给新的 CustomButton 实例,将其 xy 坐标设置为各 10 像素,然后将该实例添加到显示列表中。CustomButton 类覆盖 SimpleButton 中的 downStateupStateoverStatehitTestState 属性。其中的每一个属性都实例化一个 ButtonDisplayState 对象,这些对象将绘制不同的正方形,具体取决于 child 实例的状态。
  3. child 实例然后用于添加 MOUSE_OVER 事件侦听器和 mouseOverHandler() 侦听器方法以及 MOUSE_OUT 事件侦听器和关联的 mouseOutHandler() 方法。
  4. 事件侦听器的工作方式如下:
    • mouseOverHandler:隐藏“普通”指针并添加 MOUSE_MOVE 侦听器,该侦听器使用下述 mouseMoveHandler() 处理鼠标移动。
    • mouseOutHandler:当鼠标移动到自定义按钮之外时,显示“普通”指针,删除 MOUSE_MOVE 事件侦听器,并将自定义光标的可见性设置为 false
    • mouseMoveHandler:指针移到哪里,自定义光标就跟到哪里,并将自定义光标的可见性设置为 true
  5. 回到 MouseExample 构造函数中,将光标属性赋给新的 CustomCursor 对象,然后使用 addChild() 将该对象添加到显示列表中。每当鼠标停留在 child 之上时,CustomCursor 类会绘制一个几近黑色的小正方形来替代“普通”指针。
  6. 添加 MOUSE_LEAVE 类型的第四个事件侦听器以及关联的 mouseLeaveHandler() 方法。在此方法(如果鼠标离开舞台则调用此方法)中,向 mouseOutHandler() 传递一个新 mouseMove 侦听器对象,该对象彻底删除指针,使其不留在舞台上。
