Class FileTransfer
java.lang.Object
org.eclipse.swt.dnd.Transfer
org.eclipse.swt.dnd.ByteArrayTransfer
org.eclipse.swt.dnd.FileTransfer
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();
