[RCP]populate a treeviewer using IAdapterFactory

Question

Hello, i need help on my project based on rcp platform, i'd like to list my c:\ directory using a treeviewer and IAdapterFactory to populate it but nothing appears in my view here is my code, if somebody can help me with that.
the code in my view to create the tree viewer :
private TreeViewer treeViewer;
private IAdapterFactory adapterFactory = new MyAdapterFactory();
public void createPartControl(Composite parent) {
// TODO Auto-generated method stub
treeViewer = new TreeViewer(parent, SWT.BORDER
| SWT.MULTI | SWT.V_SCROLL);
Platform.getAdapterManager().registerAdapters(adapterFactory, File.class);
getSite().setSelectionProvider(treeViewer);
treeViewer.setLabelProvider(new WorkbenchLabelProvider());
treeViewer.setContentProvider(new BaseWorkbenchContentProvider());
treeViewer.setInput(new File("c:\\"));
...and the code to populate it :
import java.io.File;
import org.eclipse.core.runtime.IAdapterFactory;
import org.eclipse.jface.resource.ImageDescriptor;
import org.eclipse.ui.model.IWorkbenchAdapter;
public class MyAdapterFactory implements IAdapterFactory {
public LogescoAdapterFactory() {
super();
// TODO Auto-generated constructor stub
private IWorkbenchAdapter fileContentAdapter = new IWorkbenchAdapter() {
public Object getParent(Object o) {
return ((File)o).getParent();
public String getLabel(Object o) {
return ((File)o).getName();
public ImageDescriptor getImageDescriptor(Object object) {
return null;
public Object[] getChildren(Object o) {
Object[] kids = ((File)o).listFiles();
return kids == null ? new Object[0] : kids;
public Object getAdapter(Object adaptableObject, Class adapterType) {
// TODO Auto-generated method stub
if(adapterType == IWorkbenchAdapter.class &&
adaptableObject instanceof File)
return fileContentAdapter;
return null;
public Class[] getAdapterList() {
// TODO Auto-generated method stub
return new Class[] {IWorkbenchAdapter.class};
}I followed the tutorial from eclipse rich client platform book but i cant adapt it for my purpose.
So i post this message hoping you can help me. Thanks a lot.
