| Herança | Clipboard  Object |
A Clipboard object may contain the same information in more than one format. By supplying information in multiple formats, you increase the chances that another application will be able to use that information. Add data to a Clipboard object with the setData() method.
The standard formats are:
The standard formats are automatically translated between ActionScript data types and the native clipboard when a transfer between an AIR application and the operating system occurs. The ClipboardFormats class defines string constants for the standard format names.
You can use application-defined formats to add ActionScript objects to a Clipboard object. If an object is serializable, both a reference and a clone of the object can be made available. Object references are only valid within the originating application.
When it is computationally expensive to convert the information to be transferred into a
particular format, you can supply the name of a function that will perform the conversion
if and only if that format is read by the receiving component or application.
Add a deferred rendering function to a Clipboard object with the
setDataHandler() method.

String constants for the names of the standard formats are defined in the ClipboardFormats class. Other, application-defined, strings may also be used as format names when the data to be transferred is an object.

| getData | () | método |
public function getData(format:String, transferMode:String):Object
Gets the data in the specified format.
When a standard data format is accessed, the data is returned as a new object of the corresponding AIR type.
When an application-defined format is accessed, the value of the
transferMode parameter determines whether a reference to the original
object or an anonymous object containing a serialized copy of the original
object is returned.
When one of the "preferred" modes is specified, AIR will return the alternate
version when the preferred version is not available. When one of the "only"
modes is specified, AIR will return undefined when the desired
version is not available.
Parâmetros
format:String — the data format to return. The format string can contain one of the standard
names defined in the ClipboardFormats class, or an application-defined name.
|
|
transferMode:String — specifies whether to return a reference or serialized copy
when an application-defined data format is accessed. The value must be one
of the names defined in the ClipboardTransferMode class. This value is
ignored for the standard data formats.
|
Object — an object of the type corresponding to the data format

Boolean — true, if data in the specified format is present.

| setData | () | método |
public function setData(format:String, data:Object, serializable:Boolean = true):Boolean
Adds a representation of the information to be transferred in the specified data format.
Different representations of the same information can be added in different formats to increase the ability of other components or applications to make use of the available data. For exemplo, an image could be added as bitmap data for use by image editing applications, as a Bitmap object for use by other AIR applications, and as an encoded .png file for transfer to the native file system.
The data parameter must be the appropriate data type for the specified format:
| Format | Type | Descrição |
|---|---|---|
ClipboardFormats.TEXT_FORMAT | String | string data |
ClipboardFormats.URL_FORMAT | String | URL string |
ClipboardFormats.BITMAP_FORMAT | BitmapData | bitmap data |
ClipboardFormats.FILE_LIST_FORMAT | array of File | an array of files |
| Custom format name | any | object reference and serialized clone |
Custom format names cannot begin with "air:" or "flash:". To prevent format naming collisions when using custom formats, you may wish to use your application ID or a package name as a prefix to the format, such as, "com.exemplo.applicationName.dataPacket".
When transferring within or between AIR applications, the serializable parameter
determines whether both a reference and a copy are available, or whether only a reference to
an object is available. Set serializable to true to make both the reference
and a copy of the data object available. Set serializable to false
to make only the object reference available. Object references are only valid within the current
application so setting serializable to false will also mean that the data
in that format will not be available to other AIR applications. A component can choose to get
the reference or the copy of the object by setting the appropriate ClipboardTransferMode
when accessing the data for that format.
Note: the standard formats are always converted to native formats when data is pasted or
dragged outside an AIR application, so the value of the serializable
parameter does not affect the availability of data in the standard formats to non-AIR applications.
To defer rendering of the data for a format, use the setDataHandler() method instead.
If both the setData() and the setDataHandler() methods are used to add a
data representation with the same format name, then the handler function will never be called.
Parâmetros
format:String — The information to add.
|
|
data:Object — The format of the data.
|
|
serializable:Boolean (default = true)true for objects that can be serialized (and deserialized).
|
Boolean — true if the data was succesfully set;
false otherwise.
|
Error — If data is undefined.

| setDataHandler | () | método |
public function setDataHandler(format:String, handler:Function, serializable:Boolean = true):Boolean
Adds a reference to a handler function that produces the data for the specified format on demand. Use this method to defer creation or rendering of the data until it is actually accessed.
The handler function must return the appropriate data type for the specified format:
| Format | Return Type |
|---|---|
ClipboardFormats.TEXT_FORMAT | String |
ClipboardFormats.URL_FORMAT | String |
ClipboardFormats.BITMAP_FORMAT | BitmapData |
ClipboardFormats.FILE_LIST_FORMAT | Array of File |
| Custom format name | non-void |
The handler function will be called when and only when the data in the specified format is read. Note that the underlying data can change between time the handler is added and the time the data is read unless your application takes steps to protect the data. The handler function will be called only once. Subsequent accesses will return the data produced by the first function call.
To add data directly to this Clipboard object, use the setData() method instead.
If both the setData() and the setDataHandler() methods are called with the same
format name, then the handler function will never be called.
Parâmetros
format:String — A function that returns the data to be tranfered when called.
|
|
handler:Function — The format of the data.
|
|
serializable:Boolean (default = true)true if the object returned by handler
can be serialized (and deserialized).
|
Boolean — true if the handler was succesfully set;
false otherwise.
|
Error — If data is undefined.
