However, some capabilities of Adobe AIR are not listed as properties in the Capabilities class. They are properties of other classes:
| Property | Description |
|---|---|
NativeApplication.supportsDockIcon
| Whether the operating system supports system dock icons. |
NativeApplication.supportsMenu
| Whether the operating system supports a global application menu bar. |
NativeApplication.supportsSystemTrayIcon
| Whether the operating system supports system tray icons. |
NativeWindow.supportsMenu
| Whether the operating system supports window menus. |
NativeWindow.supportsTransparency
| Whether the operating system supports transparent windows. |
Do not use Capabilities.os or Capabilities.manufacturer to
determine a capability based on the operating system. Basing a capability on the operating system
is a bad idea, since it can lead to problems if an application does not consider all potential
target operating systems. Instead, use the property corresponding to the capability for which you
are testing.
You can send capabilities information, which is stored in the
Capabilities.serverString property as a URL-encoded string, using the
GET or POST HTTP method. The following example shows a server
string for a computer that has MP3 support and 1600 x 1200 pixel resolution and that is
running Windows XP with an input method editor (IME) installed:
A=t&SA=t&SV=t&EV=t&MP3=t&AE=t&VE=t&ACC=f&PR=t&SP=t&

Note: The value of Capabilities.language property is limited
to the possible values on this list. Because of this limitation, Adobe AIR applications
should use the first element in the Capabilities.languages
array to determine the primary user interface language for the system.
The server string is L.
See also
| languages | property |
languages:Array [read-only] | Runtime Versions: | 1.1 |
An array of strings that contain information about the user's preferred user interface languages, as set
through the operating system. The strings will contain language tags (and script and region information,
where applicable) defined by RFC4646
(http://www.ietf.org/rfc/rfc4646.txt)
and will use dashes as a delimiter (for example, "en-US" or "ja-JP").
Languages are listed in the array in the order of preference, as determined by the operating system
settings.
Operating systems differ in region information returned in locale strings. One operating system
may return "en-us", whereas another may return "en".
The first entry in the returned array generally has the same primary language ID
as the Capabilities.language property. For example, if Capabilities.languages[0]
is set to "en-US", then the language property is set to "en".
However, if the Capabilities.language property is set to "xu" (specifying
an unknown language), the first element in this array will be different. For this reason,
Capabilities.languages[0] can be more accurate than Capabilities.language.
The server string is LS.
| localFileReadDisable | property |
localFileReadDisable:Boolean [read-only] | Runtime Versions: | 1.0 |
Specifies whether read access to the user's hard disk has been
administratively prohibited (true) or allowed
(false). For content in Adobe AIR, this property
applies only to content in security sandboxes other
than the application security sandbox. (Content in the application
security sandbox can always read from the file system.)
If this property is true, AIR content outside of the
application security sandbox cannot read files from the user's
hard disk. For example, attempts to read a file on the user's
hard disk using load methods will fail if this property
is set to true.
The server string is LFD.
| manufacturer | property |
manufacturer:String [read-only] | Runtime Versions: | 1.0 |
Specifies the manufacturer of the AIR runtime, in the format "Adobe
OSName". The value for OSName
could be "Windows", "Macintosh",
"Linux", or another operating system name. The server string is M.
Do not use Capabilities.manufacturer to determine a capability based on
the operating system if a more specific capability property exists. Basing a capability on the operating
system is a bad idea, since it can lead to problems if an application does not consider all potential
target operating systems. Instead, use the property corresponding to the capability for which you
are testing. For more information, see the Capabilities class description.
| maxLevelIDC | property |
maxLevelIDC:String [read-only] | Runtime Versions: | 1.5 |
Retrieves the highest H.264 Level IDC that the client hardware supports. Media run at this level are guaranteed to run; however, media run at the highest level might not run with the highest quality. This property is useful for servers trying to target a client's capabilities. Using this property, a server can determine the level of video to send to the client.
The server string is ML.
| os | property |
os:String [read-only] | Runtime Versions: | 1.0 |
Specifies the current operating system. The os property
can return the following strings: "Windows XP", "Windows 2000",
"Windows NT", "Windows 98/ME", "Windows 95",
"Windows CE" (available only in Flash Player SDK, not in the desktop version),
"Linux", and "Mac OS X.Y.Z" (where X.Y.Z is the version number, for example:
Mac OS 10.5.2).
The server string is OS.
Do not use Capabilities.os to determine a capability based on
the operating system if a more specific capability property exists. Basing a capability on the operating
system is a bad idea, since it can lead to problems if an application does not consider all potential
target operating systems. Instead, use the property corresponding to the capability for which you
are testing. For more information, see the Capabilities class description.
| pixelAspectRatio | property |
pixelAspectRatio:Number [read-only] | Runtime Versions: | 1.0 |
Specifies the pixel aspect ratio of the screen. The server string
is AR.

Specifies the type of runtime environment. This property can have one of the following values:
"ActiveX" for the Flash Player ActiveX control used by Microsoft Internet Explorer"Desktop" for the Adobe AIR runtime (except for SWF content loaded by an HTML page, which
has Capabilities.playerType set to "PlugIn")"External" for the external Flash Player"PlugIn" for the Flash Player browser plug-in (and for SWF content loaded by
an HTML page in an AIR application)"StandAlone" for the stand-alone Flash PlayerThe server string is PT.
| screenColor | property |
screenColor:String [read-only] | Runtime Versions: | 1.0 |
Specifies the screen color. This property can have the value
"color", "gray" (for grayscale), or
"bw" (for black and white).
The server string is COL.
| screenDPI | property |

Specifies the dots-per-inch (dpi) resolution of the screen, in pixels.
The server string is DP.
| screenResolutionX | property |
screenResolutionX:Number [read-only] | Runtime Versions: | 1.0 |
Specifies the maximum horizontal resolution of the screen.
The server string is R (which returns both the width and height of the screen).
This property does not update with a user's screen resolution and instead only indicates the resolution
at the time an Adobe AIR application started.
Also, the value only specifies the main monitor.
| screenResolutionY | property |
screenResolutionY:Number [read-only] | Runtime Versions: | 1.0 |
Specifies the maximum vertical resolution of the screen.
The server string is R (which returns both the width and height of the screen).
This property does not update with a user's screen resolution and instead only indicates the resolution
at the time an Adobe AIR application started.
Also, the value only specifies the main monitor.
| serverString | property |
serverString:String [read-only] | Runtime Versions: | 1.0 |
A URL-encoded string that specifies values for each Capabilities property.
The following example shows a URL-encoded string:
A=t&SA=t&SV=t&EV=t&MP3=t&AE=t&VE=t&ACC=f&PR=t&SP=t&
SB=f&DEB=t&V=WIN%208%2C5%2C0%2C208&M=Adobe%20Windows&

version information:
WIN 9,0,0,0 // Flash Player 9 for Windows
MAC 7,0,25,0 // Flash Player 7 for Macintosh
LNX 9,0,115,0 // Flash Player 9 for Linux
Do not use Capabilities.version to determine a capability based on
the operating system if a more specific capability property exists. Basing a capability on the operating
system is a bad idea, since it can lead to problems if an application does not consider all potential
target operating systems. Instead, use the property corresponding to the capability for which you
are testing. For more information, see the Capabilities class description.
The server string is V.
