How to open child node in Tree control?

Hi All,
I am using arrayCollection in my tree control.
I want to open one child node based on name of that node.
How to open that chid node?
I tried tree.OpenItems and ExpandItem methods. IT is not working. Any idea how to do it?

write this statement
TreeObject.expandItem("the branch",true)
But make sure you dont call this statement right after you set the dataProvider for the tree object. Instead wait for a second or two and then call this statement. This delay is allow the tree object ot call it validate functions.
Let me know if it helps

How to add child node in Tree table programmetically

I have created tree table programmetically in bean.

Please let me know how to do this in bean.

How are you creating the tree pro-grammatically?
If you are adding a new node to underlying data structure and refresh the tree - the tree will get updated with the new data.

Hi,
you need to provide the full naming for the facet names. So instead of DepartmentsView you provide mypackage.DepartmentsView where you replace mypackage with the package structure of the the ViewObject

Since (as far as I know) treeNode is an interface, the real question to me is how are you implementing your treeNodes? Are you overriding the toString() method?

Save selected node in Tree control

I'm making this flex form for my school to add a new student
to the DB. When the admin clicks on a button it will open a Tree
control that displays the available courses and sections in the
following heirarchy:
Year>Semester>Course Name>Sections
Now I want that when he clicks on the button Select within
this new window showing the Tree, it will store the current
selected node and the full path to it, so that back in the original
form it will display the Year, Semester, Course name and section.
I've tried using the value and selecteditem methods from the tree
control but they are not working. Any ideas to figure out the full
path of the selected item?

You will need to climb back up the ancestor nodes to build
that path yourself.
"parent()" i believe returns the parent of the current node.

How to change font size of tree control content programatically

Hi,
Can I programtically change the font size of parent item and child item in the tree control.
In my application the parent and child items are changing programatically. ie the content of tree control is not constant it is dynamic.
I am using labview 8.6
Thank You
Assumptha.
Solved!
Go to Solution.

That does work...
To keep this line of instruction under the same title, how do you change ALL the text? not just the active cell? i've tried double clicking, then editing text properties using the font dialog (ctrl + 0) on a non-running vi, then saved it, and hit run. but it always reverts to some preset font properties values, and i don't know where they're being set....???
Any help would be greatly apprec!

How to design a listbox or tree control related to the database

Now i have a problem to design a listbox or tree control, it is designed to connect to the database, if the related element in database changed, the element in listbox or tree control should also change. i have managed to read the element in database, but i cannot input it to the listbox or tree control, since it has no input terminal that i can only use the Labeling tool and enter text into it.
is there any advise on it, maybe i can use another control rather than listbox or tree control. any suggestion would be appreciate.
Thank you
XuY

Hi Xuy,
On the front-panel, right-click on the text-ring control and select: Create\Property Node.
Then, on the diagram, right-click on the property-node and select "Strings[]".
The "strings[]" property is the array of strings available in the control - and you can change it.
Cheers!

How do you clear out a tree control?

I am editing items in a tree control, when the editing is complete, I re-build the tree to represent what I have after the edit. My process of deleting the items one-by-one has worked fine until the tree scrolled off the top, then, when I select the top-left item and delete everything under it, I miss the ones that have scrolled off the top.
What's the method/property I should use to clean out a tree in one operation? (before rebuilding)
...Dan

Tray Drool!
Originally I had, "How do you clear out a tree?". That's why I added "control".

How to create a Child node in Tree object

Hi All,
I have a thought to create a tree with a child object, that the child can able to create through by right click the parent tree having the options to create or delete the child objects.Please Suggest me if there is an possible way.
Thanks
Gopinath

Look at sample programm BCALV_TREE_DEMO,
and especially at the methods ADD_NODE or DELETE_SUBTREE of class CL_GUI_ALV_TREE.
For implementing the context menu, consider event ITEM_CONTEXT_MENU_REQUEST.

Can't get child node in tree selection listener

I am making a fusion web application using JDeveloper 11G (11.1.1.2.0).
I have created two view objects linked together. Let's call them VoDepartments and VoEmployees, linked on DepartmentId.
I hava made a tree with a af:switcher
<af:switcher id="s1" facetName="#{node.hierType.structureDefName}">
<f:facet name="view.VoDepartments">
<af:outputText value="#{node}" id="ot1"/>
</f:facet>
<f:facet name="view.VoEmployees">
<af:outputText value="#{node}" id="ot2"/>
</f:facet>
</af:switcher>I made a selection listener based on a guide by Frank Nimphius
RichTree tree1 = (RichTree) selectionEvent.getSource();
RowKeySet rks2 = selectionEvent.getAddedSet();
Iterator rksIterator = rks2.iterator();
if (rksIterator.hasNext()){
List key = (List)rksIterator.next();
JUCtrlHierBinding treeBinding = null;
treeBinding = (JUCtrlHierBinding) ((CollectionModel)tree1.getValue()).getWrappedData();
JUCtrlHierNodeBinding nodeBinding = nodeBinding = treeBinding.findNodeByKeyPath(key);
String nodeStuctureDefname = nodeBinding.getHierTypeBinding().getStructureDefName(); //Here is the nullpointerexception for employees
String employees = "view.VoEmployees";
String departments = "view.VoDepartments";
if (nodeStuctureDefname.equalsIgnoreCase(departments)){
   String dept = (String) nodeBinding.getAttribute("Department_name");
   System.out.println("Department = "+dept);
else if (nodeStuctureDefname.equalsIgnoreCase(employees)){
   String emp = (String) nodeBinding.getAttribute("First_name");
   System.out.println("Employee = "+emp);
else{
   //what the heck did the user click on? Ask him ;-)
}Pagedef:
Executables:
<iterator Binds="VoDepartments2" RangeSize="25" DataControl="AppMainDataControl" id="VoDepartments2Iterator"/>
Bindings:
<tree IterBinding="VoDepartments2Iterator" id="VoDepartments2">
<nodeDefinition DefName="view.VoDepartments" Name="VoDepartments20">
<AttrNames>
   <Item Value="DepartmentId"/>
</AttrNames>
<Accessors>
   <Item Value="VoEmployees"/>
</Accessors>
</nodeDefinition>
<nodeDefinition DefName="view.VoEmployees2" Name="VoDepartments21">
<AttrNames>
   <Item Value="First_name"/>
   <Item Value="Last_name"/>
</AttrNames>
</nodeDefinition>
</tree>The tree works just fine and list all it should list. I can click the department and my selection listener print the departments name in the console.
I can expand a department and list all employees. The problems is when I click an employee, I get null pointer exception.
I have found out that the selectin listener can't find nodeBiding for employees. So nodeBinding.getHierTypeBinding().getStructureDefName(); throw NullpointerException.
Anyone have an idea of what's wrong? Please help.

Hi,
if you open the tree binding editor, it has an entry "Target Data Source" for each of the node levels that you can use and point to an iterator binding representing the node. Not sure if this solves the issue, but chaces are.
1. create an iterator for a child VO (using the not dependent child VO instance)
2. Edit Target Data Source for the binding to e.g. ${bindings.EmployeesView1Iterator}

How to create multi node /data Tree by using few loops or small code

HI.
I WANT TO CREATE A TREE WHICH IS HAVING MULTI NUMBER OF NODE LEVEL (USER HAVE THE ABILITY TO CREATE AS MANY AS REQUIRED NODE LEVEL OR SUBLEVEL). HOW CAN I POPULATE THE TREE WITH SMALL CODE. AS EVERY NODE LEVEL NEED ON NESTED LOOP. SO HOW CAN I MANAGE TO POPULATE THE NODE WITH FEW LOOPS. OR THERE IS ANY OTHER WAY TO MANAGE THIS PROBLEM.
THANKS

Hi ,
I am trying to do the job , but i do not understand where
is the problem with my loop , i am sending it , could you
see it , and sujjest me , what to do. or if you have time
can you write the code for me. as i am very much needy for
this job.
The Table is as:-
CREATE TABLE TREE_01(
RECORD_NO NUMBER(10), --
OWN_CODE VARCHAR2(10),
PARENT_NO NUMBER(10),
PARENT_CODE VARCHAR2(10),
LEVELL NUMBER(4),
DEPT NUMBER(6),
CONSTRAINT RNO_PK PRIMARY KEY(RECORD_NO));
INSERT INTO TREE_01 VALUES(1,'1',0,'0',2,8540);
INSERT INTO TREE_01 VALUES(2,'2',0,'0',2,8540);
INSERT INTO TREE_01 VALUES(3,'3',0,'0',2,8540);
INSERT INTO TREE_01 VALUES(4,'4',0,'0',2,8540);
INSERT INTO TREE_01 VALUES(5,'1',1,'0',3,8540);
INSERT INTO TREE_01 VALUES(6,'2',1,'0',3,8540);
INSERT INTO TREE_01 VALUES(7,'3',1,'0',3,8540);
INSERT INTO TREE_01 VALUES(8,'1',3,'0',3,8540);
INSERT INTO TREE_01 VALUES(9,'2',3,'0',3,8540);
the loop shoud look like
|_DataProcessing
| |+Work_orders
| |_Programmers File
| | |_James
| | | |+Requests
| | | |+Leves
| | | |_Projects
| | | |_Projects001
| | |+Steven
|+HealthCare
|+Transportation
So the loop should be such that it can be go to any level of any node.
the Code i writter is As follows.
The Following Procedure is called in form leve
When new forms instance.

Question regarding DOM, XML and how to insert child nodes...

Hi,
I'm a QA student working on some big project.
Say you have an XML library holding some symbols by their categories, there are many categories, say we have two 'Miscellaneous' and 'Categories'.
I want to add to both categories another child:
the problem is that the way it is done now is:
symbolCategoryItem.appendChild(newSymbolNode)As you probably know, appendChild(newChild) deletes from the tree the newChild if exists, before inserting it again...
What should I do to avoid it?
