com.vaadin.ui.TreeTable

TreeTable extends the {@link Table} component so that it can also visualize ahierarchy of its Items in a similar manner that {@link Tree} does. The treehierarchy is always displayed in the first actual column of the TreeTable.

The TreeTable supports the usual {@link Table} features like lazy loading, soit should be no problem to display lots of items at once. Only required rows and some cache rows are sent to the client.

TreeTable supports standard {@link Hierarchical} container interfaces, butalso a more fine tuned version - {@link Collapsible}. A container implementing the {@link Collapsible} interface stores the collapsed/expandedstate internally and can this way scale better on the server side than with standard Hierarchical implementations. Developer must however note that {@link Collapsible} containers can not be shared among several users as theyshare UI state in the container.


public class TreeTableCssTest {
    private int debugIdCounter = 0;


    public TreeTableCssTest(TestSampler parent) {
        TreeTable treeTable = new TreeTable();
        treeTable.setId("treetable" + debugIdCounter++);
        treeTable.setWidth("100%");
        parent.addComponent(treeTable);


        HierarchicalContainer hc = createHierarchicalContainer();


        treeTable.setContainerDataSource(hc);


        for (Object itemId : treeTable.getItemIds()) {
            treeTable.setCollapsed(itemId, false);
        }
    }
