Example 1 with ITreeNodeFilter

use of org.eclipse.scout.rt.client.ui.basic.tree.ITreeNodeFilter in project scout.rt by eclipse.

the class JsonTreeTest method testNodeFilter.

@Test
public void testNodeFilter() throws JSONException {
    TreeNode nodeToFilter = new TreeNode();
    nodeToFilter.setEnabled(false);
    List<ITreeNode> nodes = new ArrayList<ITreeNode>();
    nodes.add(nodeToFilter);
    nodes.add(new TreeNode());
    nodes.add(new TreeNode());
    nodes.add(new TreeNode());
    ITree tree = createTree(nodes);
    JsonTree<ITree> jsonTree = m_uiSession.createJsonAdapter(tree, null);
    String node0Id = jsonTree.getOrCreateNodeId(nodes.get(0));
    assertNotNull(node0Id);
    assertNotNull(jsonTree.optTreeNodeForNodeId(node0Id));
    tree.addNodeFilter(new ITreeNodeFilter() {

        @Override
        public boolean accept(ITreeNode node, int level) {
            return node.isEnabled();
        }

    JsonTestUtility.processBufferedEvents(m_uiSession);
    assertNull(jsonTree.optNodeId(nodes.get(0)));

    List<JsonEvent> events = m_uiSession.currentJsonResponse().getEventList();
    assertEquals(1, events.size());
    assertEventTypeAndNodeIds(events.get(0), "nodesDeleted", node0Id);
}

Example 3 with ITreeNodeFilter

use of org.eclipse.scout.rt.client.ui.basic.tree.ITreeNodeFilter in project scout.rt by eclipse.

the class JsonTreeTest method testMultipleFilterChanged.

@Test

    System.out.println("Response #1: " + response);
    String node0000Id = jsonTree.getNodeId(node0000);
    JsonTestUtility.endRequest(m_uiSession);
    // --------------------------------------
    // 3 events: filterChanged, nodeChanged, filterChanged
    // filterChanged events are converted to nodesDeleted event in JsonTree.
    // Because of coalesce the nodeChanged event will be removed (it is obsolete, because nodes are deleted and re-inserted later).
    tree.addNodeFilter(new ITreeNodeFilter() {

        @Override
        public boolean accept(ITreeNode node, int level) {
            return node.isEnabled();
