i believe that maybe a better solution could be to: 1) generate serverside an xml or a json array (this is occupy less bandwidth) instead of the arraylist... 2) change rootnode to an asynctreenode... 3) associate a TreeLoader (json) or a XMLTreeLoader (xml) 4) set the url on the treeLoader -> treeLoader.setDataUrl(url of the file or of a servlet responding a json/xml string) 4) call a reload in this way -> personRoot.reload();
i believe this solution is the smartest and simplest.... infact simply calling a reload of the rootNode will connect to server and update the tree.... bye Pat PS Sorry for the in-existent .refresh :( 2009/7/23 subbu <[email protected]> > > Hi all, > There is no TreePanel.refresh() method.How can we reload the > tree.Please give me a solution.Is there any standard method for > reloading the tree with out refreshing the page.If we refresh the page > it will come.The following is my code . > > > > final TreePanel personDriverPanel = new TreePanel(); > personDriverPanel.setBodyStyle("background- > color:#EEEEEE"); > personDriverPanel.setCollapsible(true); > personDriverPanel.setIconCls("world-icon"); > personDriverPanel.setAnimate(true); > personDriverPanel.setEnableDD(true); > personDriverPanel.setContainerScroll(true); > personDriverPanel.setAutoScroll(true); > personDriverPanel.setRootVisible(true); > personDriverPanel.setFrame(true); > personDriverPanel.setAutoHeight(true); > personDriverPanel.setTitle("Persons/Drivers"); > personDriverPanel.setWidth(200); > personDriverPanel.setHeight(250); > personDriverPanel.setId("panleid"); > > final TreeNode personRoot = new TreeNode("Persons"); > personRoot.setId("rootPerson"); > > personRoot.addListener(new TreeNodeListenerAdapter() > { > public void onDblClick(Node node, EventObject e) > { > GWT.log("Node Row " + > node.getAttribute("nbr") + " clicked", > null); > // HOW DO I KNOW IF THE CHECKBOX IS CHECKED > FROM THIS CODE BLOCK? > personDriverPanel.expandAll(); > // window.show(); > } > }); > > > personDriverPanel.addListener(new TreePanelListenerAdapter() > { > public void onContextMenu(TreeNode root, EventObject > e) { > int[] xy = e.getXY(); > showPersonDriverMenu(root, e); > } > }); > > > greetingService.buildPersonDetails(new > AsyncCallback<Object>(){ > public void onFailure(Throwable caught){ > // > com.google.gwt.user.client.Window.alert("Fail"); > } > @SuppressWarnings("unchecked") > public void onSuccess(Object result) { > > ArrayList<PersonDriver> a = > (ArrayList<PersonDriver>) result; > TreeNode parent[] = new TreeNode[a.size()]; > for(int i=0;i<a.size();i++) > { > //System.out.println("Person > nameddd:"+a.get(i).getPersonName()); > parent[i] = new > TreeNode(a.get(i).getPersonName()); > parent[i].setExpanded(false); > parent[i].setAttribute("PersonID", > "personname"); > > parent[i].setId(a.get(i).getPersonId().toString()); > personRoot.appendChild(parent[i]); > } > > //System.out.println("Depth:::"+personRoot.getDepth()); > > } > }); > > personRoot.setExpanded(true); > personDriverPanel.setRootNode(personRoot); > personDriverPanel.expandAll(); > > > > Thanks and Regards, > Subash > > On Jul 20, 5:46 pm, Patrizio De Michele <[email protected]> wrote: > > try reloading it.... > > if your root is an asynctreenode call reload....it'll go to server and > > reload the entire tree... > > otherwise add a node to the tree and call myTreePanel.refresh() > > > > 2009/7/20 subbu <[email protected]> > > > > > > > > > Hi, > > > I had created a tree in gwt ext .I had got values from db and > > > its showing.Now i want to right click on the root node and add another > > > entry .Its adding in db but not showing in the tree.Is it possible to > > > refresh the tree. > > > > > thanks and regards, > > > Subash > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "GWT-Ext Developer Forum" group.
