window.runtime property | window.runtime.flash.display.Screen |
Inheritance | Screen EventDispatcher Object |
Runtime Versions: | 1.0 |
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.

Method | Defined By | ||
---|---|---|---|
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 | ||
dispatchEvent(event:Event):Boolean
Dispatches an event into the event flow. | EventDispatcher | ||
getScreensForRectangle(rect:Rectangle):Array [static]
Returns the (possibly empty) set of screens that intersect
the provided rectangle. | Screen | ||
hasEventListener(type:String):Boolean
Checks whether the EventDispatcher object has any listeners registered for a specific type
of event. | EventDispatcher | ||
hasOwnProperty(name:String):Boolean
Indicates whether an object has a specified property defined. | Object | ||
isPrototypeOf(theClass:Object):Boolean
Indicates whether an instance of the Object class is in the prototype chain of the object specified
as the parameter. | Object | ||
propertyIsEnumerable(name:String):Boolean
Indicates whether the specified property exists and is enumerable. | Object | ||
removeEventListener(type:String, listener:Function, useCapture:Boolean = false):void
Removes a listener from the EventDispatcher object. | EventDispatcher | ||
setPropertyIsEnumerable(name:String, isEnum:Boolean = true):void
Sets the availability of a dynamic property for loop operations. | Object | ||
toLocaleString():String
Returns the string representation of this object, formatted according to locale-specific conventions. | Object | ||
toString():String
Returns the string representation of the specified object. | Object | ||
valueOf():Object
Returns the primitive value of the specified object. | Object | ||
willTrigger(type:String):Boolean
Checks whether an event listener is registered with this EventDispatcher object or any of
its ancestors for the specified event type. | EventDispatcher |
bounds | property |
bounds:Rectangle
[read-only] Runtime Versions: | 1.0 |
The bounds of this screen.
The screen location is relative to the virtual desktop.
On Linux systems that use certain window managers, this property returns the desktop bounds, not the screen's visible bounds.
Example ( How to use this example )
var screenBounds = air.Screen.mainScreen.bounds;
colorDepth | property |
colorDepth:int
[read-only] Runtime Versions: | 1.0 |
The color depth of this screen (expressed in number of bits).
Example ( How to use this example )
var colors = air.Screen.mainScreen.colorDepth;
mainScreen | property |
mainScreen:Screen
[read-only] Runtime Versions: | 1.0 |
The primary display.
Example ( How to use this example )
var primaryScreen = air.Screen.mainScreen;
screens | property |
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.
Example ( How to use this example )
var screenArray = air.Screen.screens;
visibleBounds | property |
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.
Example ( How to use this example )
var screenBounds = air.Screen.mainScreen.visibleBounds;
getScreensForRectangle | () | method |
public 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.
|
Array — An array of Screen objects containing the screens that contain any
part of the area defined by the rect parameter.
|
Example ( How to use this example )
var rect = new air.Rectangle(-200, 100, 1000, 600); var intersectedScreens = air.Screen.getScreensForRectangle(rect);
