Adobe AIR clipboard class allows you to copy data and objects through clipboard. The operating system clipboard can be accessed by generalClipboard property.
Data to the clipboard can be added by setData() or setDataHandler method and to retrive Data from clipboard use getData()
Example
Clipboard.generalClipboard.setData(ClipboardFormats.TEXT_FORMAT,"some Text value to clipboard");
Clipboard.generalClipboard.getData(ClipboardFormats.TEXT_FORMAT);
The formats supported by Adobe AIR
BITMAP_FORMAT: a BitmapData object
FILE_LIST_FORMAT: an array of File objects
HTML_FORMAT: HTML-formatted string data
TEXT_FORMAT: string data
RICH_TEXT_FORMAT: a ByteArray containing Rich Text Format data
URL_FORMAT: a URL string
ClipboardFormats defines these constants
For Example to get a text from clipboard check if the clipboard contains text before converting it to string by using
if(Clipboard.generalClipboard.hasformat(ClipboardFormats.TEXT_FORMAT)){
var clipboardtextvalue:String = Clipboard.generalClipboard.getData(ClipboardFormats.TEXT_FORMAT);
}
Hasformat returns true or false
To clear clipboard use Clipboard.generalClipboard.clear();
The following simple example demonstrates how to copy a Text to clipboard and also how to retrive the same.
