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,
