Package org.eclipse.swt.dnd
Class TextTransfer
java.lang.Object
org.eclipse.swt.dnd.Transfer
org.eclipse.swt.dnd.ByteArrayTransfer
org.eclipse.swt.dnd.TextTransfer
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.
