import com.vaadin.event.ItemClickEvent;
import com.vaadin.server.FileResource;
import com.vaadin.server.VaadinService;
import com.vaadin.ui.*;
import java.io.File;

public class DocumentTreeView extends VerticalLayout {
    // A menu tree
    Tree docCtgList = new Tree();

    public DocumentTreeView(){

        // An item with hierarchy
        docCtgList.addItem("Category Documents");
        docCtgList.addItem("SPAJ");
        docCtgList.addItem("SPAK");

        docCtgList.setChildrenAllowed("SPAJ", false);
        docCtgList.setChildrenAllowed("SPAK", false);

        docCtgList.setParent("SPAJ", "Dokumen Penutupan Polis");
        docCtgList.setParent("SPAK", "Dokumen Penutupan Polis");

        docCtgList.setImmediate(true);
        docCtgList.expandItem("Dokumen Penutupan Polis");

        addComponent(docCtgList);
        setSizeFull();

        docCtgList.addItemClickListener( new ItemClickEvent.ItemClickListener() {
            @SuppressWarnings("deprecation")
            public void itemClick(ItemClickEvent event) {

                // Pick only left mouse clicks
                if (event.getButton() == ItemClickEvent.BUTTON_LEFT)
                    Notification.show("Left Click",
                                      Notification.Type.HUMANIZED_MESSAGE);
                    // Find the application directory
                    String basepath = VaadinService.getCurrent()
                            .getBaseDirectory().getAbsolutePath();

                    // Image as a file resource
                                    FileResource resource = new FileResource(new File (basepath +
                                                                                              "images/icon/32/search.png"));

                    // Show the image in the application
                                    Image image = new Image("Image from file", resource);

                    // Let the user view the file in browser or download it
                                    Link link = new Link("Link to the image file", resource);

            }
        });
    }
