Class TextTransfer

java.lang.Object
org.eclipse.swt.dnd.Transfer
org.eclipse.swt.dnd.ByteArrayTransfer
org.eclipse.swt.dnd.TextTransfer
public class TextTransfer extends ByteArrayTransfer
The class TextTransfer provides a platform specific mechanism for converting plain text represented as a java String to a platform specific representation of the data and vice versa.

An example of a java String containing plain text is shown below:

    String textData = "Hello World";

Note the TextTransfer does not change the content of the text data. For a better integration with the platform, the application should convert the line delimiters used in the text data to the standard line delimiter used by the platform.
