public final class Screen
继承Screen Inheritance EventDispatcher Inheritance Object

语言版本: ActionScript 3.0
运行时版本: AIR 1.0

Screen 类提供此应用程序的可用显示屏幕的相关信息。

屏幕是位于可能更大的“虚拟桌面”内的独立桌面区域。虚拟桌面的原点是操作系统指定的主屏幕的左上角。因此,个别显示屏幕范围的坐标可能是负数。虚拟桌面也可能有一些不在任何显示屏幕内的区域。

Screen 类包括用于访问可用屏幕对象的静态类成员和用于访问个别屏幕属性的实例成员。屏幕信息不应进行缓存,因为这些信息可能会由用户随时更改。

请注意,屏幕和连接到计算机的物理监视器之间不一定有一对一的对应关系。例如,两台监视器可以显示同一个屏幕。

无法直接实例化 Screen 类。调用 new Screen() 构造函数将引发 ArgumentError 异常。

属性详细信息
    

bounds

属性
bounds:Rectangle  [只读]

语言版本: ActionScript 3.0
运行时版本: AIR 1.0

此屏幕的范围。

屏幕位置相对于虚拟桌面。

在使用某些窗口管理器的 Linux 系统中,此属性返回桌面边界,而不是屏幕的可视边界。



实现
    public function get bounds():Rectangle

示例  ( 如何使用本示例 )
下面的示例显示如何获取屏幕(在本例中为主显示屏幕)的范围:
import flash.display.Screen;
import flash.geom.Rectangle;

var mainScreen:Screen = Screen.mainScreen;
var screenBounds:Rectangle = mainScreen.bounds;
    

colorDepth

属性 
colorDepth:int  [只读]

语言版本: ActionScript 3.0
运行时版本: AIR 1.0

此屏幕的颜色深度(以位数为单位)。



实现
    public function get colorDepth():int

示例  ( 如何使用本示例 )
下面的示例显示如何获取屏幕(在本例中为主显示屏幕)的颜色深度:
var mainScreen:Screen = Screen.mainScreen;
var colors:uint = mainScreen.colorDepth;
    

mainScreen

属性 
mainScreen:Screen  [只读]

语言版本: ActionScript 3.0
运行时版本: AIR 1.0

主显示器。



实现
    public static function get mainScreen():Screen

示例  ( 如何使用本示例 )
下面的示例显示如何获取表示此计算机的“主”屏幕的 Screen 对象。
var primaryScreen:Screen = Screen.mainScreen;
    

mode

属性 
mode:ScreenMode

语言版本: ActionScript 3.0
运行时版本: AIR 29.0

Screen 对象的当前屏幕模式。mode 属性表示特定 Screen 设备的当前屏幕模式。



实现
    public function get mode():ScreenMode
    public function set mode(value:ScreenMode):void
    

modes

属性 
modes:Array  [只读]

语言版本: ActionScript 3.0
运行时版本: AIR 29.0

Screen 对象的各 ScreenMode 对象的数组。modes 属性表示特定 Screen 设备的受支持屏幕模式。



实现
    public function get modes():Array
    

screens

属性 
screens:Array  [只读]

语言版本: ActionScript 3.
运行时版本: AIR 1.0

当前可用的屏幕的数组。

修改返回的数组对可用的屏幕没有任何效果。



实现
    public static function get screens():Array

示例  ( 如何使用本示例 )
下面的示例显示如何获取包含可用屏幕的数组:
var screenArray:Array = Screen.screens;
    

visibleBounds

属性 
visibleBounds:Rectangle  [只读]

语言版本: ActionScript 3.0
运行时版本: AIR 1.0

此屏幕上可以看见窗口的区域范围。

屏幕的 visibleBounds 在 Windows 中不包括任务栏(和其他停靠的桌面栏),而在 Mac OS X 中则不包括菜单栏和停靠栏(具体取决于系统设置)。在某些 Linux 配置中无法确定可见边界。在这些情况下,visibleBounds 属性返回与 screenBounds 属性相同的值。



实现
    public function get visibleBounds():Rectangle

示例  ( 如何使用本示例 )
下面的示例显示如何获取屏幕(在本例中为主显示屏幕)的可用范围:
import flash.display.Screen;
import flash.geom.Rectangle;

var mainScreen:Screen = Screen.mainScreen;
var screenBounds:Rectangle = mainScreen.visibleBounds;
方法详细信息

    getScreensForRectangle

()方法
public static function getScreensForRectangle(rect:Rectangle):Array

语言版本: ActionScript 3.0
运行时版本: AIR 1.0

返回一组与提供的矩形相交的屏幕(可能为空)。

参数

rect:Rectangle — 一个具有相对于虚拟桌面原点(主屏幕的左上角)的坐标的矩形。

返回
Array — 包含屏幕的 Screen 对象的数组,这些屏幕包含由 rect 参数定义的区域的任何部分。

示例  ( 如何使用本示例 )

下面的示例显示如何获取至少包含给定矩形一部分的屏幕的数组:
import flash.display.Screen;
import flash.geom.Rectangle;

var rect:Rectangle = new Rectangle(-200, 100, 1000, 600);
var intersectedScreens:Array = Screen.getScreensForRectangle(rect);
ScreenExample.as

下面的示例通过定义 DockingWindow 类来创建一个停靠在屏幕某一侧的窗口。执行下列步骤可完成该任务:
  1. 响应键盘事件以确定停靠在屏幕的哪一侧。
  2. 访问静态 Screen 类方法 getScreensForRectangle() 可以获取当前显示该窗口的屏幕的 Screen 对象。
  3. 根据屏幕尺寸重新设置窗口范围。
  4. 根据新窗口尺寸重新绘制窗口内容。

请注意,此类旨在用作具有 SystemChrome="none"transparent="true" 设置的 AIR 应用程序的根类。要在具有系统镶边的窗口中使用此类,在计算窗口位置和大小时,必须将镶边的粗细和窗口的最小宽度考虑在内。

[ X ]为什么显示为英语?
《ActionScript 3.0 参考》中的内容以英语显示

《ActionScript 3.0 参考》中的部分内容未翻译成所有语言。当某个语言元素未翻译时,将显示为英语。例如,ga.controls.HelpBox 类未翻译成任何语言。因此在简体中文版的参考中,ga.controls.HelpBox 类显示为英语。
