InheritanceScreen Inheritance EventDispatcher
Runtime Versions:  1.0

The Screen class provides information about the display screens available to this application.

Screens are independent desktop areas within a possibly larger "virtual desktop." The origin of the virtual desktop is the top-left corner of the operating-system-designated main screen. Thus, the coordinates for the bounds of an individual display screen may be negative. There may also be areas of the virtual desktop that are not within any of the display screens.

The Screen class includes static class members for accessing the available screen objects and instance members for accessing the properties of an individual screen. Screen information should not be cached since it can be changed by a user at any time.

Note that there is not necessarily a one-to-one correspondance between screens and the physical monitors attached to a computer. For example, two monitors may display the same screen.

You cannot instantiate the Screen class directly. Calls to the new Screen() constructor throw an ArgumentError exception.

addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void
Registers an event listener object with an EventDispatcher object so that the listener receives notification of an event.
EventDispatcher
 Inherited
Dispatches an event into the event flow.

[static] Returns the (possibly empty) set of screens that intersect the provided rectangle.

removeEventListener(type:String, listener:Function, useCapture:Boolean = false):void
Removes a listener from the EventDispatcher object.

Property Detail
boundsproperty
bounds:Rectangle  [read-only]
Runtime Versions:  1.0

The bounds of this screen.

The screen location is relative to the virtual desktop.

colorDepthproperty 
colorDepth:int  [read-only]
Runtime Versions:  1.0

The color depth of this screen (expressed in number of bits).

mainScreenproperty 
mainScreen:Screen  [read-only]
Runtime Versions:  1.0

The primary display.

screensproperty 
screens:Array  [read-only]
Runtime Versions:  1.0

The array of the currently available screens.

Modifying the returned array has no effect on the available screens.

visibleBoundsproperty 
visibleBounds:Rectangle  [read-only]
Runtime Versions:  1.0

The bounds of the area on this screen in which windows can be visible.

The visibleBounds of a screen excludes the task bar (and other docked desk bars) on Windows, and excludes the menu bar and, depending on system settings, the dock on Mac OS X. On some Linux configurations, it is not possible to determine the visible bounds. In these cases, the visibleBounds property returns the same value as the screenBounds property.

Method Detail
getScreensForRectangle()method
function getScreensForRectangle(rect:Rectangle):Array
Runtime Versions:  1.0

Returns the (possibly empty) set of screens that intersect the provided rectangle.

Parameters

rect:Rectangle — A rectangle with coordinates relative to the origin of the virtual desktop, which is the top-left corner of the primary screen.

Returns
Array — An array of Screen objects containing the screens that contain any part of the area defined by the rect parameter.
