UIX:Tree Control
Hi,
Has anybody used or know to use the UIX:Tree control part of the UIX Simple JSP Components? If so can you please tell me if this helps creating a DHTML Tree component?
Thanks
mn
Hello there,
You should check out the "Data Trees" chapter of the UIX Developer's Guide. It goes into a lengthy description of the tree component and how to code it in UIX. The tree component does not use DHTML, but rather rerenders based on its state (what is expanded and collapsed).

Hi
I have created ADF UIX Tree Component on my screen and i want to have button expand all / collapse all for my tree .
Can i create event for expand all / collapse all ADF UIX Tree ?
If i can ,could you please advise how i should to do ?
ThanksHi Daniel,
Are there any one can tell me when the new ADF UIX
demo based on uix 2.2 be released?I'm not sure when any sample applications will be released, but there is an ADF UIX tutorial available here:
http://otn.oracle.com/products/jdev/collateral/tutorials/9050/adfuix_tut.html
I want to know if we can get databind uix tree
component (or other ui components) from ADF data
action control which return dataobject and something
else.I'm not sure about the tree component - I'll try to find out whether that is/will be supported. Once your data controls are available in the Data Control Palette, you can bind them to components in your UIX page by:
1. Selecting the data control that you want to bind.
2. Selecting a component type from the "Drop As" choice.
3. Dragging the data control onto the UIX page.
This process is illustrated in the tutorial above.

How can I display and change built-in symbols of a tree control programmatically?
I want to set the built-in symbols of a tree control during runtime.
I only found an example to assign custom pictures but not how to select one of the 40 built-in symbol.
Many Thanks
Solved!
Go to Solution.The ActiveItem.SymbolIndex will allow you to select the symbol for the active item. You can use the ListBox Symbol Ring Constant (Dialog and User Interface palette) to select a symbol (or you can just enter the number directly if you know what it is).

Not able to get the database data into the Tree Control
Hi Everybody,
I have to populate the tree control with nodes and items, which is to be populated from the database, and the tree control is <b>dynamic</b>. I mean, there is a <b>toolbar</b>, whenever a <b>pushbutton is clicked</b>, depending on that the tree contents has to be changed.
If anybody had worked with <b>CL_GUI_COLUMN_TREE</b> control to get the data from database, depending upon the <b>pushbutton selected in Toolbar</b>, please paste the seudocode for it.

How to get all items under a parent item in a tree control
Hello,
I have 2 questions regarding a tree control:
1) Is there any way to specify a parent item tag and get an array of ALL its sub item tags? For example, in the attached vi, specify the Parent#2 parent tag and get an array containing Item#P21 and Item#P22
2) Is there a way to specify a range to the ActiveCell property. For example, all items from line#1 to line number#3
Any ideas?

Did you try a search? There's no direct way of doing this. You have to navigate the tree and build up an array. You can find an example here: http://forums.ni.com/t5/LabVIEW/get-all-children-of-a-parent-in-tree/td-p/729548
2) Is there a way to specify a range to the ActiveCell property. For example, all items from line#1 to line number#3
No. (It's called ActiveCell, not ActiveCells) Presumably you are trying to perform an operation on multiple items. Unfortunately, you need to use a loop. You should defer panel updates if you're doing this a lot. -
Uix:Tree - How to populate in jsp ?
Hello all,
I'm having trouble to know how to populate an <uix:tree> in a JSP page. I see the UIX Developer's guide and the SimpleTreeData example and the documentation about uix:jsp is very poor. The data that will be posted in the <uix:tree> was provided by IFS. Then, I populate a DataObjectList with the files name. The point is that I don't know how to make a link between this DataObjectList, populated in a class(*.JAVA) file and the <uix:tree>(*.JSP) file. I wanna know how to use only <uix:jsp> and don't use *.UIX files, only *.JSP and *.JAVA files, ok ?
Here are some code part :
This is the JSP file
<%@ taglib uri="http://xmlns.oracle.com/uix/ui" prefix="uix" %>
<%@ page import="Hierarquia" %>
<%@ page import="oracle.cabo.ui.data.DataObjectList" %>
<%@ page contentType="text/html;charset=windows-1252"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>
Ifs - Publicação de Documentos
</title>
</head>
<uix:document>
<uix:styleSheet />
<body>
<uix:body>
<uix:pageLayout>
<uix:contents>
<uix:form name="teste">
<uix:contents>
<%
DataObjectList dados = null;
Hierarquia x = new Hierarquia();
x.conecta();
x.populateTree();
dados = x.getResultSet();
%>
<uix:formattedText text="Teste" />
<uix:tree id="arvore_teste" nodesBinding="????" formName="teste">
</uix:tree>
</uix:contents>
</uix:form>
</uix:contents>
</uix:pageLayout>
</uix:body>
</body>
</uix:document>
</html>
Thanks folks !

I believe that the best way to do this is to use scriptable variables, eg:
<uix:tree id="arvore_teste">
<%
// Assuming "dados" contains your tree data
arvore_teste.setNodes(dados);
%>
</uix:tree>See the "Scriptable Variables" section in the "UIX JSP Tag Libraries" chapter of the UIX Developer's Guide for more info...

How to binding incoming xml node list to the tree control as dataProvider
Recently, I faced into one issue: I want to binding incoming xml node (it's not avaliable at start) list to the tree control as a dataProvider.
Since the incoming xml node list is not avaliable at beginning but I needs to bind it to the tree, so I create one virtual one in the xml, and prepare to remove it before the tree is shown. (ready for the actual node adding). But It did not work.
Please see the presudo-code here:
1. Model layer(CsModel.as)
public class CsModel
[Bindable]
public var treeXML:XML=<nodes><car label="virtualOne" id="1">
</car></nodes>;
(Here, I want to build binding relationship on the <car/> node,
one 'virtual/stub' node is set here with lable="virtualOne".
But this node will be deleted after IdTree
control is created completely.)
[Bindable]
public var treeData:XMLList =new XMLListCollection(treeXML.car);
2. view layer(treePage.mxml)
private var _model:CsModel = new CsModel();
private function addNode():void
var newNode:XML=<car/>;
newNode.@label="newOne";
newNode.@id=1;
_model.treeXML.appendChild(newNode);
private function cleanData():void
delete _model.treeXML.car;
<mx:VBox height="100%" width="100%">
<mx:Button label="AddNode" click="addNode()" />
<mx:Tree id="IdTree" labelField="@label"
creationComplete="cleanData()"
dataProvider="{_model}"/>
</mx:VBox>
3. Top view layer (App.Mxml)
<mx:application>
<treePage />
</mx:application>
For method: cleanData()，It's expected that when the treePage is shown, we first delete the virutalOne to provide one 'clear' tree since we don't want show virtualOne to the user. The virutalOne node just for building the relationship between treeData and treeXML at beginning. But the side effect of this method, I found, is that the relationship between treeXML and treeData was cut off. And this leads to that when I added new node (by click the 'addNode' button) to the xmlXML, the xmlData was not affected at all !
So Is there any other way to solve this issue or bind the incoming xml node list to the xmlListCollection which will be used as Tree control's dataProvider ?If u want to display the name : value then u can do like this
<xsl:eval>this.selectSingleNode("name").nodeName</xsl:eval> : <xsl:value-of select="name" /> -
How can I save the all the values of a tree control ?
I have a problem, in run time, I adds new items on a tree control, but i don´t know how I can save the values of the child text of each item in a file.
Thanks.I'm no expert on the tree control, but I made a small example to save all items to a textfile, including item tag, item string, and indent level. One drawback of this method is that it fully expands the tree regardless how the user left it. To go the other direction, you'd have to write a routine to go through the text file and programmatically build the tree.
To master the tree control, I think you have to resort to creating a control reference for it and using the Invoke Node to do some operations. For another approach to traversing and operating on a tree, check out the "Traversing Tree Controls and Setting Custom Symbols" (search the NI Developer Zone site).
Best of luck,
John

How can I drag and drop an item from one Tree control to another in LabVIEW 7.1?
You can use the mouse up and down event on the two tree controls but the problem is making the correct selection in the second tree control. I want to be able to switch over to the selection bar of the second tree control so that I can place my item in the correct position. I know all possible workarounds with double-clicks and so on... but I really want a windows drag and drop.
This is what I have for the moment. Please check the library below. I need to activate the selection bar of the second tree control somehow to get the position in the control. The VI below is written in LV 7.1

Drag&Drop.llb 65 KBHi Jones,
As far as I know this feature is currently not supported by the Tree control. A workaround, would be to use the vertical position of the mouse in the button up event to determine what line you�re dropping the item.
If you would like the Tree control to include the drag and drop feature, please submit this as a Product Suggestion under the feedback at www.ni.com/contact.
Good luck!

How to use the drop event of the tree control in LabVIEW 8.20?
Hi,
I am using the two tree controls in my application to provide a option for the user to drag and drop item from one tree to the other. I have to validate the user selection. I tried to capture the user drop event using the event structure. The problem I am facing is, I am not able to drop the item even though i have wired a constant true to the filter(Accepted?) in the event case. I have enable the property(Allow droping) in the right menu of the tree control also.
While configuring an event case for (drop, drag entered and some thing like this) only I am getting the problem otherwise it is working fine.
What do i need to do to caprture the drop event ?
Is there any way to avoid the item duplication while droping a new item in the tree control ?
or how can i do this?
Thanks,
Pandiarajan RHi Pandiarajan,
I hope you are doing well today! There is a lengthy discussion on the Tree Control Drag & Drop feature at this forums post including contributions from the developer of the Drag & Drop feature:
Tree Control Drag & Drop in LabVIEW 8
By avoiding item duplication, do you mean that you don't want the same item to be in the old tree control or do you not want more than one item in the new tree control?

How to get position of a ring in a tree control?
Ok, this is probably a stupid question, but how does one get the position of a ring inside of a tree control? I have a tree with two columns, with rings in the second column. I can set the position using SetTreeCellRingValueFromIndex(), but how does one get the position after the user has modified the control? I found the functions GetTreeCellRingIndexFromValue() and GetTreeCellRingValueFromIndex() but I haven't found a way to get either the Index or the Value of the ring (what I'm looking for is the index, but if I can obtain the value I can go from there). Thanks in advance!
Solved!
Go to Solution.Hi,
You can use GetTableCellVal function to get the value of the ring.
There is not special "ring" function for that. Maybe that's what you were searching for
From the value you can get to the index using the functions you are already aware of.
Hope this helps,

How do I get the tag of a selected line in a tree control ?
I am running LabVIEW 7.1.
I want to be able to add a parent or sibling to a tree to a selected item in a tree.The tag of the selected item is actually the output of the tree control itself. If you create an indicator from the tree control, you will get a duplicate tree control (indicator), but if you wire the output into a string indicator, the tag of the selected item will show up. You can an item to the tree by wiring the tree reference into an invoke node, calling the method "Edit Tree Items: Add Item", and wiring the output of the tree control (which will be the tag of the selected item) into the "Parent Tag" terminal. This method will only let you add a child to an item, you cannot add a parent or sibling. Items cannot have multiple parents, so it wouldn't make sense to add a parent; and to add a sibling for the selected item, you could call the method "Navigate Tree: Get Parent" and pass the tag of the parent into the "Edit Tree Items: Add Item" method.

How to render image in tree control without embed it
Hello frndz i am working on tree control and want to show imagein its node through xml list collection.i have searched a lot for this but in every example with tree control images are embeded.i dont want to hardcode the image.Need to make the image comes from database(Xml).so is there any live or demo example for tree control.
Thanks in Advance
Vineet oshoif you decompile the imaging.ear file, there is a web.xml file which you can add the following parameter:
<context-param>
<param-name>oracle.adf.view.rich.security.FRAME_BUSTING</param-name>
<param-value>never</param-value>
</context-param>
or take a look at Receiving "Warning: Unable to load content in a frame. Frame content will load at the top level." When Trying to Use the <af:inlineFrame> Component [ID 1266770.1] on Oracle Support.
Make sure you take a copy of the imaging app before you make changes. You can then upload back through the weblogic console.

Hi,
I need to program an input screen for values that have hierarchical dependencies (e.g. sums). I feel, the most adequate user-interface would be a tree control, because of the data dependencies and also because the users asked for a possibility to collapse/expand parts of the data during input.
I had a look at CL_GUI_COLUMN_TREE, but I'm not sure, if it can be used for data input. Has anyone done something like this before or can anybody direct me to some additional sample coding? (the sample coding in the reuse library didn't do it...)
Thanks for your help, greetings, Kathrin!Hello Kathrin,
Since you say that the user's input is hierarchical in nature, it is nice to have a tree-control for input. But, the choice of using a custom-control-version of the tree is a cause for some concern. I cannot recollect any of the SAP screens where the input can be given through such a tree framework (please do let me know if you have come across one). The problem with such a tree would be in the areas of even-handling. Filling the tree with appropriate data at the right times would be another challenge.
However, there's one alternative that I would like to direct your attention to. You must have observed another kind of tree, when you select an application component from the APPLICATION HIERARCHY, which is just like a list. Also, the <i>Transport Organizer (SE09)</i>, <i>Menu Painter (SE41)</i> etc., have this kind of a tree. You can use this if you (or rather your users) are very particular on having a tree display. For more information, you can see the Function Group <b>SEUT</b>, which has the required function modules to accomplish the same. The Function Group is well documented, and you might have to work a little on the function modules themselves.
Please do let me know if this is a suitable option to meet your requirement. All the best,
Regards,
Anand Mandalika.
