Class FileTransfer

java.lang.Object
org.eclipse.swt.dnd.Transfer
org.eclipse.swt.dnd.ByteArrayTransfer
org.eclipse.swt.dnd.FileTransfer
public class FileTransfer extends ByteArrayTransfer
The class FileTransfer provides a platform specific mechanism for converting a list of files represented as a java String[] to a platform specific representation of the data and vice versa. Each String in the array contains the absolute path for a single file or directory.

An example of a java String[] containing a list of files is shown below: 

     File file1 = new File("C:\temp\file1");
     File file2 = new File("C:\temp\file2");
     String[] fileData = new String[2];
     fileData[0] = file1.getAbsolutePath();
     fileData[1] = file2.getAbsolutePath();
