IFSSystemView (JTOpen 20.0.7 API)

java.lang.Object
- javax.swing.filechooser.FileSystemView
- - com.ibm.as400.access.IFSSystemView

public class IFSSystemView
extends FileSystemView

Provides a gateway to the IBM i integrated file system, for use when constructing javax.swing.JFileChooser objects.

JFileChooser is a standard Java way to build dialogs for navigating and choosing files.

The following example demonstrates the use of IFSSystemView.

 
 import com.ibm.as400.access.AS400;
 import com.ibm.as400.access.IFSJavaFile;
 import com.ibm.as400.access.IFSSystemView;
 import javax.swing.JFileChooser;
 import java.awt.Frame;
 
 // Work with directory /Dir on the system myAS400.
 AS400 system = new AS400("myAS400");
 IFSJavaFile dir = new IFSJavaFile(system, "/Dir");
 JFileChooser chooser = new JFileChooser(dir, new IFSSystemView(system));
 Frame parent = new Frame();
 int returnVal = chooser.showOpenDialog(parent);
 if (returnVal == JFileChooser.APPROVE_OPTION) {
    IFSJavaFile chosenFile = (IFSJavaFile)(chooser.getSelectedFile());
    System.out.println("You selected the file named " +
                        chosenFile.getName());
 }
