InheritanceNativeWindow Inheritance EventDispatcher Inheritance Object

The NativeWindow class provides an interface for creating and controlling native desktop windows.

A reference to the NativeWindow instance is returned by the window constructor. A reference to a NativeWindow instance can also be accessed using the stage.nativeWindow property of any display object on that window's stage:

var window:NativeWindow = displayObject.stage.nativeWindow;

The properties of a NativeWindow instance can only be accessed by application content. If non-application content attempts to access the NativeWindow object, a security error will be thrown.

Content can be added to a window using the DisplayObjectContainer methods of the Stage object such as addChild().

You cannot not add Flex components directly to the display list of a NativeWindow instance. Instead, use the Flex mx:WindowedApplication and mx:Window components to create your windows and add the other Flex components as children of those objects. You can add Flex-based SWF content directly to a NativeWindow window as long as the SWF file is loaded into its own application domain and is application content.

To create a root HTML window for displaying HTML content it is typically easier to create the window with HTMLLoader.createRootContent(). Windows created in this way will have an HTMLLoader object added automatically. (From JavaScript code, you can also use the JavaScript window.open() function. However, this method gives you less control over the window appearance and behavior.)

The following operations on NativeWindow objects are asynchronous: close(), maximize(), minimize(), restore(), and bounds changes. An application can detect when these operations have completed by listening for the appropriate events.

If the NativeApplication.autoExit property is true, which is the default, the application will close when its last window is closed (and all close event handlers have returned). If autoExit is false, then NativeApplication.nativeApplication.exit() must be called to terminate the application.

NativeWindow objects will not be garbage collected after the window constructor has been called and before close() has been called. It is the responsibility of the application to close its own windows.

Property Detail
AIR-only activeproperty
active:Boolean  [read-only]

Indicates whether this window is the active application window.

Use the activate() method to make a window active.


Implementation
    public function get active():Boolean

See also

AIR-only alwaysInFrontproperty 
alwaysInFront:Boolean  [read-write]

Specifies whether this window will always be in front of other windows (including those of other applications).

There are two groups of windows in the system depth order. Windows in the alwaysInFront group are always displayed in front of all other windows. Depth ordering between windows within the same group is determined normally. In other words, activating a window will bring it in front of other windows in its group.

Changing alwaysInFront from false to true will bring the window to the top of all other windows. Changing the property from true to false will send the window to the back of "alwaysInFront" windows, but still in front of other windows. Setting the property to its current value will not change the window depth order.

The alwaysInFront property should rarely be set to true since windows with this setting will appear in front of the windows of other applications even when the other application is active.

Note: On Mac® OS X, setting alwaysInFront to true will have no effect when the displayState property of the window stage is fullScreen or fullScreenInteractive.


Implementation
    public function get alwaysInFront():Boolean
    public function set alwaysInFront(value:Boolean):void

Example

The following examples force a window to be displayed in front of all other windows (that are not similarly forced to the front):
windowObj.alwaysInFront = true;

With a reference to a display object on the window stage:
displayObject.stage.nativeWindow.alwaysInFront=true;

From a JavaScript routine running in an HTMLLoader object in the window (or a root HTML window):
window.nativeWindow.alwaysInFront = true;
AIR-only boundsproperty 
bounds:Rectangle  [read-write]

The size and location of this window.

The dimensions of a window include any system chrome. The dimensions of a window's stage are equal to the dimensions of the window, minus the size of any system chrome. Changing the width and height of the window will change the stage's stageWidth and stageHeight. The reverse also applies; changing the stage dimensions will change the window size.

In a root HTML window, the outerWidth and outerHeigth properties are equivalent to the window height and width properties. The innerWidth and innerHeight properties equal the stage.stageWidth and stage.stageHeight properties minus the thickness of any automatic scrollbars displayed by the window.

A resize event is dispatched whenever the width or height of this window changes. Likewise, a move event is dispatched whenever the origin (x,y) of this window changes. Setting the bounds property directly will not dispatch a moving or resizing event. To allow other components to prepare for or cancel an impending move or resize operation, your bounds-changing logic can dispatch moving and resizing events with the NativeWindow dispatchEvent() method and then check whether the event was canceled by a registered listener.

Setting the bounds property of a window is equivalent to setting its x, y, width, and height properties. Likewise, setting any of the individual dimensions is equivalent to setting the bounds property. When you set all the dimensions at the same time by using the bounds property, fewer events are displatched.

If the width and the height specified are less than the minimum or greater than the maximum allowed size, because of the minSize and maxSize properties of the window or the minimum and maximum operating system limits, then the window dimensions are set to the closest legal size. The minimum width and height of any displayed system chrome may also result in a window that is larger than the specified size.


Implementation
    public function get bounds():Rectangle
    public function set bounds(value:Rectangle):void

Throws
ArgumentError — If the rectangle is null or contains invalid values.
 
IllegalOperationError — If the bounds property is accessed after this window has been closed.

See also


Example

The following examples set the bounds of a window with a reference to a NativeWindow object:
windowObj.bounds = new Rectangle(200, 200, 1000, 800);

With a reference to a display object on the window stage:
displayObject.stage.nativeWindow.bounds = new Rectangle(20, 20, 800, 600);

From a JavaScript routine running in an HTMLLoader object in the window (or a root HTML window):
window.nativeWindow.bounds = new air.Rectangle(20, 20, 800, 600);
AIR-only closedproperty 
closed:Boolean  [read-only]

Indicates whether this window has been closed.

Accessing the following properties on a closed window will throw an illegal operation error:

Likewise, calling the following methods on a closed window will also throw an illegal operation error:


Implementation
    public function get closed():Boolean

Example

The following examples show how to access the closed property of a window:
var isWindowClosed:Boolean = windowObj.closed;

With a reference to a display object on the window stage:
var isWindowClosed:Boolean = displayObject.stage.nativeWindow.closed;

From a JavaScript routine running in an HTMLLoader object in the window (or root HTML window):
var isWindowClosed = window.nativeWindow.closed;
AIR-only displayStateproperty 
displayState:String  [read-only]

The display state of this window.

Constants for the possible values are defined in the NativeWindowDisplayState class:


Implementation
    public function get displayState():String

Throws
IllegalOperationError — If the displayState property is accessed after this window has been closed.

See also


Example

The following example shows how to get the current window display state given a reference to the window object:
var state:String = windowObj.displayState;
AIR-only heightproperty 
height:Number  [read-write]

The height of this window in pixels.

The dimensions of a window include any system window chrome that is displayed. The height of the usable display area inside a window is available from the Stage.stageHeight property.

Changing the height property of a window is equivalent to changing the height through the bounds property.

If the height specified is less than the minimum or greater than the maximum allowed height, because of the minSize and maxSize properties of the window or the minimum and maximum operating system limits, then the window height is set to the closest legal size.


Implementation
    public function get height():Number
    public function set height(value:Number):void

Throws
ArgumentError — If the value set is null or invalid.
 
IllegalOperationError — If the property is accessed after this window has been closed.

See also

AIR-only maximizableproperty 
maximizable:Boolean  [read-only]

Reports the maximizable setting used to create this window.

The maximizable setting cannot be changed after a window is created.


Implementation
    public function get maximizable():Boolean

Throws
SecurityError — When trying to set to false without sufficient privilege.
 
IllegalOperationError — If the property is accessed after this window has been closed.

See also

AIR-only maxSizeproperty 
maxSize:Point  [read-write]

The maximum size for this window.

The size limit is specified as the coordinates of a Point object. The point x property corresponds to the window width, the y property to the window height.

The maxSize restriction is enforced for window resizing operations invoked both through ActionScript code and through the operating system.

Setting maxSize will change the window bounds if the current bounds are larger than the new maximum size.

Note: Maximizing a window will only enlarge the window to the maxSize value even if the maximized window will be smaller than the operating system screen. The window will still be in the maximized display state.


Implementation
    public function get maxSize():Point
    public function set maxSize(value:Point):void

Throws
IllegalOperationError — If assigned size is not within the operating system minimum and maximum window sizes.
 
SecurityError — If size is forbidden for the content's current privilege.
 
ArgumentError — If the size is null or contains invalid values.
 
IllegalOperationError — If the maxSize property is accessed after this window has been closed.

See also


Example

The following examples show how to set the maximum allowed size for a window.
windowObj.maxSize = new Point(1040,920);

With a reference to a display object on the window stage:
displayObject.stage.nativeWindow.maxSize = new Point(800,600);

From a JavaScript routine running in an HTMLLoader object in a window (or in a root HTML window):
window.nativeWindow.maxSize = new air.Point(960,960);
AIR-only menuproperty 
menu:NativeMenu  [read-write]

The native menu for this window.

When a NativeMenu object is assigned to the window menu property, a native menu will be displayed for a window if NativeWindow.supportsMenu is true, unless the window systemChrome property is NativeWindowSystemChrome.NONE.

Note: Assigning a menu to a window when NativeWindow.supportsMenu is false or when the window systemChrome property is NativeWindowSystemChrome.NONE is allowed, but does nothing.


Implementation
    public function get menu():NativeMenu
    public function set menu(value:NativeMenu):void

See also

AIR-only minimizableproperty 
minimizable:Boolean  [read-only]

Reports the minimizable setting used to create this window.

The minimizable setting cannot be changed after a window is created.


Implementation
    public function get minimizable():Boolean

Throws
SecurityError — When trying to set to false without sufficient privilege.
 
IllegalOperationError — If the property is accessed after this window has been closed.

See also

AIR-only minSizeproperty 
minSize:Point  [read-write]

The minimum size for this window.

The size limit is specified as the coordinates of a Point object. The point x property corresponds to the window width, the y property to the window height.

Setting minSize, will change the window bounds if the current bounds are smaller than the new minimum size.

The minSize restriction is enforced for window resizing operations invoked both through ActionScript code and through the operating system.

Note: The width and height of any displayed system chrome may make it impossible to set a window as small as the specified minimum size.


Implementation
    public function get minSize():Point
    public function set minSize(value:Point):void

Throws
IllegalOperationError — If the assigned size is not within the operating system minimum and maximum window sizes.
 
SecurityError — If size is forbidden for the content's current privilege.
 
ArgumentError — If the size is null or contains invalid values.
 
IllegalOperationError — if the minSize property is accessed after this window has been closed.

See also


Example

The following examples show how to set the minimum allowed size for a window:
windowObj.minSize = new Point(200,80);

With a reference to a display object on the window stage:
displayObject.stage.nativeWindow.minSize = new Point(120,60);

From a JavaScript routine running in an HTMLLoader object in a window (or in a root HTML window):
window.nativeWindow.minSize = new air.Point(80,60);
AIR-only resizableproperty 
resizable:Boolean  [read-only]

Reports the resizable setting used to create this window.

The resizable setting cannot be changed after a window is created.


Implementation
    public function get resizable():Boolean

Throws
SecurityError — When trying to set to false without sufficient privilege.
 
IllegalOperationError — If the property is accessed after this window has been closed.

See also

AIR-only stageproperty 
stage:Stage  [read-only]

The Stage object for this window. The Stage object is the root object in the display list architecture used in ActionScript 3.0-based SWF content.

The stage is the root of the display list for the window. Add visual display objects to a window by adding them to the stage or to another object already in the display list of this stage. The stage dimensions are those of the window client area when the window uses system chrome. The stage dimensions are equal to the dimensions of the window if system chrome is not used.


Implementation
    public function get stage():Stage

See also


Example

The following example shows how to set stage properties for a NativeWindow instance:
import flash.display.StageAlign;

windowObj.stage.align = StageAlign.TOP_LEFT;
AIR-only supportsMenuproperty 
supportsMenu:Boolean  [read-only]

Indicates whether AIR supports native window menus on the current computer system.

When NativeWindow.supportsMenu is true, a native menu will be displayed for a window when a NativeMenu object is assigned to the window menu property (unless the window systemChrome property is NativeWindowSystemChrome.NONE).

Note: Assigning a menu to a window when NativeWindow.supportsMenu is false or when the window systemChrome property is NativeWindowSystemChrome.NONE is allowed, but does nothing.


Implementation
    public static function get supportsMenu():Boolean

See also

AIR-only supportsNotificationproperty 
supportsNotification:Boolean  [read-only]

Indicates whether AIR supports window notification cueing on the current computer system.

When NativeWindow.supportsNotification is true, calling the window's notify() method will result in a visual cue to the user that an event of interest has occurred. This visual cue will conform to the operating system convention of the native system. For example, on Windows®, the task bar icon will flash.

Note: Calling notify() when NativeWindow.supportsNotification is false is allowed, but does nothing.


Implementation
    public static function get supportsNotification():Boolean

See also

AIR-only systemChromeproperty 
systemChrome:String  [read-only]

Reports the system chrome setting used to create this window.

The values returned by NativeWindow.systemChrome will be one of the constants defined in the NativeWindowSystemChrome class.

The system chrome setting cannot be changed after a window is created.


Implementation
    public function get systemChrome():String

Throws
SecurityError — When trying to set to false without sufficient privilege.
 
IllegalOperationError — If the property is accessed after this window has been closed.

See also


Example

The following example :

With a reference to a display object on the window stage:
var sysChromeType:String = displayObject.stage.nativeWindow.systemChrome;

From a JavaScript routine running in an HTMLLoader object in the window (or root HTML window):
var sysChromeType = window.nativeWindow.systemChrome;

The following example shows how to change the apparent system chrome and transparency settings by creating a new window and moving all child display objects to the new window:
import flash.display.NativeWindow;
import flash.display.NativeWindowSystemChrome;
import flash.display.NativeWindowInitOptions;

public function deChromeWindow(oldWindow:NativeWindow):NativeWindow{
    if(oldWindow.systemChrome != NativeWindowSystemChrome.NONE){
        var newOptions:NativeWindowInitOptions = new NativeWindowInitOptions();
        newOptions.systemChrome = NativeWindowSystemChrome.NONE;
        newOptions.transparent = true;
        
        var newWindow:NativeWindow = new NativeWindow(newOptions);
        newWindow.stage.stageWidth = oldWindow.stage.stageWidth;
        newWindow.stage.stageHeight = oldWindow.stage.stageHeight;
        newWindow.stage.align = oldWindow.stage.align;
        newWindow.stage.scaleMode = oldWindow.stage.scaleMode;
        
        for(var i:int = 0; i < oldWindow.stage.numChildren; i++){
            newWindow.stage.addChild(oldWindow.stage.getChildAt(i));
        }
        newWindow.activate();
        oldWindow.close();
        
        return newWindow;
    }
    return oldWindow;
}

AIR-only systemMaxSizeproperty 
systemMaxSize:Point  [read-only]

The largest window size allowed by the operating system.

The size limit is specified as the coordinates of a Point object. The point x property corresponds to the window width, the y property to the window height.


Implementation
    public static function get systemMaxSize():Point
AIR-only systemMinSizeproperty 
systemMinSize:Point  [read-only]

The smallest window size allowed by the operating system.

The size limit is specified as the coordinates of a Point object. The point x property corresponds to the window width, the y property to the window height.


Implementation
    public static function get systemMinSize():Point
AIR-only titleproperty 
title:String  [read-write]

The window title.

The title will appear in the system chrome for the window, if displayed, as well as in other system-dependent locations (such as the task bar).


Implementation
    public function get title():String
    public function set title(value:String):void

Throws
IllegalOperationError — If the property is accessed after this window has been closed.

Example

The following example sets the title of a window object:
windowObj.title = "Window Title";
AIR-only transparentproperty 
transparent:Boolean  [read-only]

Reports the transparency setting used to create this window.

The transparent property cannot be changed after a window is created. Transparency affects both the visual appearance and the mouse behavior of the window. If the alpha value of a pixel is below a certain threshold, which varies between about .06 and .01 depending on the operating system, then the window will not capture mouse events above that pixel.


Implementation
    public function get transparent():Boolean

Throws
SecurityError — When trying to set to false without sufficient privilege.
 
IllegalOperationError — If the property is accessed after this window has been closed.

See also

AIR-only typeproperty 
type:String  [read-only]

Reports the window type setting used to create this window.

The values returned by NativeWindow.type will be one of the constants defined in the NativeWindowType class.

The type setting cannot be changed after a window is created.


Implementation
    public function get type():String

Throws
SecurityError — When trying to set to false without sufficient privilege.
 
IllegalOperationError — If the property is accessed after this window has been closed.

See also

AIR-only visibleproperty 
visible:Boolean  [read-write]

Specifies whether this window is visible.

An invisible window is not displayed on the desktop, but all window properties and methods are valid.

By default, visible is set to false. To display a window, set visible to true or call NativeWindow.activate().

Note: On Mac OS X, setting visible=false on a minimized window will not remove the window icon from the dock. If a user subsequently clicks the dock icon, the window will return to the visible state and be displayed on the desktop.


Implementation
    public function get visible():Boolean
    public function set visible(value:Boolean):void

Throws
SecurityError — When trying to set to false without sufficient privilege.
 
IllegalOperationError — If the property is accessed after this window has been closed.

See also


Example

The following examples show how to access the visible property of a window:
windowObj.visible = true;

With a reference to a display object on the window stage:
displayObj.stage.nativeWindow.visible = true;

From a JavaScript routine running in an HTMLLoader object in the window (or root HTML window):
window.nativeWindow.visible = true;
AIR-only widthproperty 
width:Number  [read-write]

The width of this window in pixels.

The dimensions reported for a native window include any system window chrome that is displayed. The width of the usable display area inside a window is available from the Stage.stageWidth property.

Changing the width property of a window is equivalent to changing the width through the bounds property.

If the width specified is less than the minimum or greater than the maximum allowed width, because of the minSize and maxSize properties of the window, or the minimum and maximum operating system limits, then the window width is set to the closest legal size.


Implementation
    public function get width():Number
    public function set width(value:Number):void

Throws
ArgumentError — If the value set is null or invalid.
 
IllegalOperationError — If the property is accessed after this window has been closed.

See also

AIR-only xproperty 
x:Number  [read-write]

The horizontal axis coordinate of this window's top left corner relative to the origin of the operating system desktop.

On systems with more than one monitor, x can be negative. If you save the value, perhaps to reposition a window at its previous location, you should always verify that the window is placed in a usable location when the position is restored. Changes in screen resolution or monitor arrangement can can result in a window being placed off screen. Use the Screen class to obtain information about the desktop geometry.

Changing the x property of a window is equivalent to changing the location through the bounds property.


Implementation
    public function get x():Number
    public function set x(value:Number):void

Throws
ArgumentError — If the value set is null or invalid.
 
IllegalOperationError — If the property is accessed after this window has been closed.

See also

AIR-only yproperty 
y:Number  [read-write]

The vertical axis coordinate of this window's top left corner relative to the upper left corner of the operating system's desktop.

On systems with more than one monitor, y can be negative. If you save the value, perhaps to reposition a window at its previous location, you should always verify that the window is placed in a usable location when the position is restored. Changes in screen resolution or monitor arrangement can can result in a window being placed off screen. Use the Screen class to obtain information about the desktop geometry.

Changing the y property of a window is equivalent to changing the location through the bounds property.


Implementation
    public function get y():Number
    public function set y(value:Number):void

Throws
ArgumentError — If the value set is null or invalid.
 
IllegalOperationError — If the property is accessed after this window has been closed.

Constructor Detail
AIR-only NativeWindow()Constructor
public function NativeWindow(initOptions:NativeWindowInitOptions)

Creates a new NativeWindow instance and a corresponding operating system window.

The settings defined in the initOptions parameter cannot be changed after the window is created. Invalid initOptions settings will cause an illegal operation error to be thrown. Settings that are valid but not available on the current system will not throw an exception. The window capabilities specific to the current operating system can be detected, if desired, using the static NativeWindow members such as systemMaxSize.

The default window size is determined by the operating system, but can be changed by setting the window bounds. The change will not be visible if the window visible property is false.

Parameters
initOptions:NativeWindowInitOptions — An object containing the initialization properties for this window.

Throws
IllegalOperationError — If the initOptions parameter is invalid.

Example

The following example creates and activates a new NativeWindow instance:
import flash.display.NativeWindowInitOptions;
import flash.display.NativeWindowSystemChrome;
import flash.display.NativeWindowType;
import flash.display.NativeWindow;
import flash.display.StageAlign;
import flash.display.StageScaleMode;
import flash.geom.Rectangle;

var windowOptions:NativeWindowInitOptions = new NativeWindowInitOptions();
windowOptions.systemChrome = NativeWindowSystemChrome.STANDARD;
windowOptions.type = NativeWindowType.NORMAL;

var newWindow:NativeWindow = new NativeWindow(windowOptions);

AIR-only activate()method
public function activate():void

Activates this window.

Activating a window will:

Example

The following examples show how to activate a window.

With a reference to a display object on the window stage:

displayObject.stage.nativeWindow.activate();

With a reference to an instance of the NativeWindow class:
windowObj.activate();

From JavaScript in an HTML page rendered in the window (where window is the global JavaScript window object):
window.nativeWindow.activate();
AIR-only close()method 
public function close():void

Closes this window.

A close event is dispatched as soon as the close operation is complete. A closing event will not be dispatched. If cancellation of the close operation should be allowed, dispatch a closing event and check whether any registered listeners cancel the default behavior before calling the close() method.

If display object instances that are currently in the window are not referenced elsewhere they will be garbage collected and destroyed, except on the initial application window created by AIR. To allow display objects on the initial window to be garbage collected, remove them from the window stage.

After being closed, the NativeWindow object is still a valid reference, but accessing most properties and methods will throw an illegal operation error.

Closed windows cannot be reopened. If the window is already closed, no action is taken and no events are dispatched.

Note: to hide a window without closing it, set the window's visible property to false.

Example

The following examples show how to close a window:

With a reference to the NativeWindow instance (windowObj):

windowObj.close();


With a reference to a display object on the window stage:
displayObj.stage.nativeWindow.close();

From a JavaScript routine running in an HTMLLoader object (or HTML root window):
window.close(); //overriddable in HTMLHost

Or:
window.nativeWindow.close(); //not overriddable

The following example illustrates how to allow cancellation of a close operation (where windowObj is the NativeWindow instance to be closed):
public function closeCommand():Boolean{
    var closeEvent:Event = new Event(Event.CLOSING,true,true);
    windowObj.dispatchEvent(closeEvent);
    if(!closeEvent.isDefaultPrevented()){
        windowObj.close();
        return true;
    } else {
      return false;
    }
}

The following example illustrates how to close a window from a JavaScript routine running in an HTMLLoader object (or HTML root window), while allowing the operation to be canceled:
<script src="AIRAliases.js" type="text/javascript"></script>
<script type="text/javascript">
    var dirtyData = false;
    function closeWindow(){
            var closingEvent = new air.Event(air.Event.CLOSING,true,true);
            window.nativeWindow.dispatchEvent(closingEvent);
               if(!closingEvent.isDefaultPrevented()){
                   window.nativeWindow.close();
                //or use: window.close(); 
               return true;
           } else {
               return false;
        }
    }
        
    function onClosing(event){
        if(dirtyData){
            event.preventDefault();
            //Save data...
        }
    }    

    window.nativeWindow.addEventListener(air.Event.CLOSING,onClosing);        
</script>
AIR-only globalToScreen()method 
public function globalToScreen(globalPoint:Point):Point

Converts a point in pixel coordinates relative to the origin of the window stage (a global point in terms of the display list), to a point on the virtual desktop.

Virtual desktop coordinates are relative to the upper, lefthand corner of the primary monitor.

Parameters

globalPoint:Point — The point on the stage to convert to a point on the screen.

Returns
Point — The specified global point relative to the desktop.

AIR-only maximize()method 
public function maximize():void

Maximizes this native window.

Calling maximize() method dispatches a displayStateChange event, and, if applicable, a move and a resize event. Whereas system chrome will dispatch a displayStateChanging event that can be canceled when a maximize command is initiated by a user, your maximize logic must implement this behavior, if desired.

The maximize() method executes asynchronously. To detect the completion of the state change, listen for the displayStateChange event.

If the window is already maximized, no action is taken and no events are dispatched.

Note: On operating systems, such as Mac OS X, in which maximizing a window does not also prevent resizing, calling maximize() will zoom the window to fill the screen, but will not prevent subsequent resizing of the window. Resizing a zoomed window will also restore the display state.


Throws
IllegalOperationError — If the maximizable property of this window is false or if the method is called after this window has been closed.

See also


Example

The following example illustrates how to allow cancelation of a maximize operation:
public function maximizeWindow(nativeWin:NativeWindow):Boolean{
  if(nativeWin.displayState != NativeWindowDisplayState.MAXIMIZED){
    var beforeState:String = nativeWin.displayState;
    var afterState:String = NativeWindowDisplayState.MAXIMIZED;
    var displayStateEvent:NativeWindowDisplayStateEvent = 
        new NativeWindowDisplayStateEvent(NativeWindowDisplayStateEvent.DISPLAY_STATE_CHANGING,
                                              true,true,beforeState,afterState);
    nativeWin.dispatchEvent(displayStateEvent);
    if(!displayStateEvent.isDefaultPrevented()){
        nativeWin.maximize();
        return true;
    } else {
      return false;
    }
  }
  return false;
}

The following example illustrates how to allow cancelation of a maximize operation from a JavaScript routine running in an HTMLLoader object on the window (or an HTML window):
function maximizeWindow(nativeWin){
    if(nativeWin.displayState != air.NativeWindowDisplayState.MAXIMIZED){
        var beforeState = nativeWin.displayState;
        var afterState = air.NativeWindowDisplayState.MAXIMIZED;
        var displayStateEvent = 
            new air.NativeWindowDisplayStateEvent(air.NativeWindowDisplayStateEvent.DISPLAY_STATE_CHANGING,
                                              true,true,beforeState,afterState);
        nativeWin.dispatchEvent(displayStateEvent);
        if(!displayStateEvent.isDefaultPrevented()){
            nativeWin.maximize();
            return true;
        } else {
          return false;
        }
     }
     return false;
}
AIR-only minimize()method 
public function minimize():void

Minimizes this native window.

Calling minimize() dispatches a displayStateChange event, and, if applicable, a move and a resize event. Whereas system chrome will dispatch a displayStateChanging event that can be canceled when a minimize command is initiated by a user, calling minimize() directly does not. Your minimize logic may implement this behavior, if desired.

The minimize() method executes asynchronously. To detect the completion of the state change, listen for the displayStateChange event.

If the window is already minimized, no action is taken and no events are dispatched.


Throws
IllegalOperationError — If the minimizable property of this window is false or if the method is called after this window has been closed.

Example

The following example illustrates how to allow cancelation of a call to minimize() by dispatching a displayStateChanging event:
public function minimizeWindow(nativeWin:NativeWindow):Boolean{
    if(nativeWin.displayState != NativeWindowDisplayState.MINIMIZED){
        var beforeState:String = nativeWin.displayState;
        var afterState:String = NativeWindowDisplayState.MINIMIZED;
        var displayStateEvent:NativeWindowDisplayStateEvent = 
            new NativeWindowDisplayStateEvent(NativeWindowDisplayStateEvent.DISPLAY_STATE_CHANGING,
                                              true,true,beforeState,afterState);
        nativeWin.dispatchEvent(displayStateEvent);
        if(!displayStateEvent.isDefaultPrevented()){
            nativeWin.minimize();
            return true;
        } else {
          return false;
        }
     }
     return false;
}

The following example illustrates how to allow cancelation of a call to minimize() in JavaScript running in an HTMLLoader object (or HTML window):

        var beforeState = window.nativeWindow.displayState;
        var afterState = air.NativeWindowDisplayState.MINIMIZED;
        var displayStateEvent = 
            new air.NativeWindowDisplayStateEvent(air.NativeWindowDisplayStateEvent.DISPLAY_STATE_CHANGING,
                                              true,true,beforeState,afterState);
        window.nativeWindow.dispatchEvent(displayStateEvent);
        if(!displayStateEvent.isDefaultPrevented()){
            window.nativeWindow.minimize();
            return true;
        } else {
          return false;
        }
     }
     return false;
}
AIR-only notifyUser()method 
public function notifyUser(type:String):void

Triggers a visual cue through the operating system that an event of interest has occurred.

When NativeWindow.supportsNotification is true, the visual cue will conform to the operating system convention of the native system. For example, on Windows, the task bar icon will flash.

The type parameter determines the intensity of the cue. Constants for the permitted values are defined in the NotificationType class, and may be:

The cues provided for informational notifications are of short duration; those provided for critical notifications will last until the user activates this window.

Note: Calling notifyUser() when NativeWindow.supportsNotification is false is allowed, but does nothing.

Parameters

type:String — A string representing the urgency of the notification.

AIR-only orderInBackOf()method 
public function orderInBackOf(window:NativeWindow):Boolean

Sends this window directly behind the specified window.

Does not activate or acquire the focus for the window or the application. Minimized or hidden (visible is false) windows cannot be reordered.

Parameters

window:NativeWindow — An application window.

Returns
Booleantrue if this window was succesfully sent to the back; false if this window is invisible or minimized.

Example

The following examples show how to move a window just below another window with references to the NativeWindow instances:
windowBehind.orderInBackOf(windowFront);

With references to display objects on the window stages:
displayObjBehind.stage.nativeWindow.orderInBackOf(displayObjectFront.stage.nativeWindow);


From a JavaScript routine running in an HTMLLoader object (or HTML root window) using references to two JavaScript Window objects:
jsWindowObjBehind.nativeWindow.orderInBackOf(jsWindowObjFront.nativeWindow);
AIR-only orderInFrontOf()method 
public function orderInFrontOf(window:NativeWindow):Boolean

Brings this window directly in front of the specified window.

Does not activate or acquire the focus for the window or the application. Minimized or hidden (visible is false) windows cannot be reordered.

Parameters

window:NativeWindow — An application window.

Returns
Booleantrue if this window was succesfully brought to the front; false if this window is invisible or minimized.

Example

The following examples show how to move a window just above another window with references to the NativeWindow instances:
windowFront.orderInFrontOf(windowBehind);

With references to display objects on the window stages:
displayObjFront.stage.nativeWindow.orderInFrontOf(displayObjectBehind.stage.nativeWindow);


From a JavaScript routine running in an HTMLLoader object (or HTML root window) using references to two JavaScript window objects:
jsWindowObjFront.nativeWindow.orderInFrontOf(jsWindowObjBehind.nativeWindow);

AIR-only orderToBack()method 
public function orderToBack():Boolean

Sends this window behind any other visible windows.

Does not activate or acquire the focus for this window or the application. Minimized or hidden (visible is false) windows cannot be reordered.

If alwaysInFront is true, then calling this method will not send this window behind any windows which have alwaysInFront set to false.

Returns
Booleantrue if this window was succesfully sent to the back; false if this window is invisible or minimized.

Example

The following examples show how to move a window behind all other windows in the application (with the same alwaysInFront setting):
windowObj.orderToBack();


With a reference to a display object on the window stage:
displayObj.stage.nativeWindow.orderToBack();

From a JavaScript routine running in an HTMLLoader object in the window (or a root HTML window):
window.nativeWindow.orderToBack();

AIR-only orderToFront()method 
public function orderToFront():Boolean

Brings this window in front of any other visible windows.

Does not activate or acquire the focus for this window or the application. Minimized or hidden (visible is false) windows cannot be reordered.

If alwaysInFront is false, then calling this method will not send this window in front of any windows which have alwaysInFront set to true.

Returns
Booleantrue if this window was succesfully brought to the front; false if this window is invisible or minimized.

Example

The following examples show how to move a window in front of all other windows in the application (with the same alwaysInFront setting):
windowObj.orderToFront();


With a reference to a display object on the window stage:
displayObj.stage.nativeWindow.orderToFront();

From a JavaScript routine running in an HTMLLoader object in the window (or a root HTML window):
window.nativeWindow.orderToFront();

AIR-only restore()method 
public function restore():void

Restores this window from either a minimized or a maximized state.

Calling restore() dispatches a displayStateChange event, and, if applicable, a move and a resize event. Whereas system chrome will dispatch a displayStateChanging event that can be canceled when a restore command is initiated by a user, your restore logic must implement this behavior, if desired.

The restore() method executes asynchronously. To detect the completion of the state change, listen for the displayStateChange event.

If the window is already in the NativeWindowDisplayState.NORMAL state, no action is taken and no events are dispatched.


Throws
IllegalOperationError — If the method is called after this window has been closed.

Example

The following example illustrates how to allow cancelation of a restore operation:
public function restoreWindow(nativeWin:NativeWindow):Boolean{
    if(nativeWin.displayState != NativeWindowDisplayState.NORMAL){
        var beforeState:String = nativeWin.displayState;
        var afterState:String = NativeWindowDisplayState.NORMAL;

        }
     }
     return false;
}
AIR-only startMove()method 
public function startMove():Boolean

Starts a system-controlled move of this window.

When called from a mouseDown event, this method begins a mouse-driven move sequence that continues until a mouseUp event occurs.

When called from other code this method begins a keyboard- or mouse-driven move sequence consistent with the operating system's default sequence.

During a move sequence, a series of events will be dispatched as the window origin moves. For each incremental move, first a moving event is dispatched and then, if the moving event is not canceled, the window location is updated and a move event is dispatched. If a moving event is canceled, the move sequence is immediately terminated.

Returns
Booleantrue if the move was succesfully initiated and false if the window is maximized.

Throws
IllegalOperationError — If the method is called after this window has been closed.

Example

The following example shows how to move a window in response to a mouseDown event:
import flash.display.NativeWindow;
import flash.events.MouseEvent;

public class MovableWindow extends NativeWindow{
    private function MovableWindow():void{
        super(new NativeWindowInitOptions());
        this.stage.addEventListener(MouseEvent.MOUSE_DOWN, onMoveCommand);
        this.activate();
    }
    
    private function onMoveCommand(event:MouseEvent):void{
        this.startMove();
    }
}
AIR-only startResize()method 
public function startResize(edgeOrCorner:String):Boolean

Starts a system-controlled resize operation of this window.

When called from a mouseDown event handler this method begins a mouse-driven resizing sequence that continues until a mouseUp event occurs.

When called from other code this method begins a keyboard- or mouse-driven resizing sequence consistent with the operating system's default sequence.

During the resize sequence, a series of events will be dispatched as the window dimensions change. For each incremental change, first a resizing event is dispatched and then, if the resizing event is not canceled, the window dimensions are updated and a resize event is dispatched. If a resizing event is canceled, the the sequence is immediately terminated.

Parameters

edgeOrCorner:String (default = NaN) — A constant from the NativeWindowResize class that specifies which edge or corner of this window to resize. The following are valid values:

ValueVertical alignmentHorizontal alignment
NativeWindowResize.TOP TopCenter
NativeWindowResize.BOTTOM BottomCenter
NativeWindowResize.LEFT CenterLeft
NativeWindowResize.RIGHT CenterRight
NativeWindowResize.TOP_LEFT TopLeft
NativeWindowResize.TOP_RIGHT TopRight
NativeWindowResize.BOTTOM_LEFT BottomLeft
NativeWindowResize.BOTTOM_RIGHT BottomRight
NativeWindowResize.NONE BottomRight

Returns
Booleantrue if the resize was succesfully initiated and false if the window is maximized.

Throws
IllegalOperationError — If the method is called after this window has been closed.

Example

The following example shows how to resize a window in response to a mouseDown event:
public class ResizableWindow extends NativeWindow
{
    public function ResizableWindow()
    {
        var options:NativeWindowInitOptions = new NativeWindowInitOptions();
        super(options);
        this.stage.align = StageAlign.TOP_LEFT;
        this.stage.scaleMode = StageScaleMode.NO_SCALE;
        this.stage.addEventListener(MouseEvent.MOUSE_DOWN, onResizeCommand);
        this.activate();
    }

    private function onResizeCommand(event:MouseEvent):void{
        var resizeFrom:String = "";
        if(event.localY < this.height * .33){resizeFrom = "T";}
        else if(event.localY > this.height * .66){resizeFrom = "B";}
        if(event.localX < this.width * .33){resizeFrom += "L";}
        else if(event.localX > this.width * .66){resizeFrom += "R";}
        
        this.startResize(resizeFrom);
    }    
}
