public Class FileTransfer

extends ByteArrayTransfer
Class Inheritance
Imports
org.eclipse.swt.internal.*, org.eclipse.swt.internal.gtk.*
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();
