Tree Control - Performance

Hi,
Am using a tree control in our web application created using
class - CL_GUI_LIST_TREE with checkbox items.
When a user 'checks' the item , it went to hourglass for 2 to 3 mins.
Can you please let me know, is there any fine tuning is required
at code level or is there any parameter setting at ITS Level.
We are in ITS 620 and R3 4.7.
Thanks in advance,
Srini S

Hi,
At coding level, a solution could be to subgroup the main nodes in your tree control and send the 'children' of a node only when it is clicked.
Kind Regards,

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.

How to search a tree control.

Hi all,
I just started learning Flash Builder not too long ago, quite a learning experience I have to say. I am a little lost and woul like some help from you guys.
I am trying to build a menu tree that will display and image and information about that image when the corresponding node is selected.
I also want to have the menu tree searchable, I looked at a few examples of tree controls to get some ideas but I keep hitting brickwalls left and right.
I started over few times trying to follow some of the examples. Right now, I only have the visual elements, please see the code below.
Thank you so much in advance.
Here's the code I have so far:

You should take a look at the help documentation about the tree component. They have an example code at the bottom that shows how to load in data to the tree and how to perform actions when a node in the tree is selected. Below is a link to the help documentation on the tree component.

Hello Mohit
Here is a sample routine (taken from BCALV_TREE_02) which you have to add and adapt for your report. It does two things:
1. Register events that should be handled (required but not sufficient for event handling)
2. Set event handler for registered events
The first step is different from ALV grid controls because here all events are already registered with the control (not the control framework).
Set the event handler (statement SET HANDLER) registers the event handling with the control framework.
FORM register_events.
*§4. Event registration: tell ALV Tree which events shall be passed
* from frontend to backend.

*§4a. Frontend registration(i): get already registered tree events.
* The following four tree events registers ALV Tree in the constructor
* method itself.
* - cl_gui_column_tree=>eventid_expand_no_children
* (needed to load data to frontend when a user expands a node)
* - cl_gui_column_tree=>eventid_header_context_men_req
* (needed for header context menu)
* - cl_gui_column_tree=>eventid_header_click
* (allows selection of columns (only when item selection activated))
* - cl_gui_column_tree=>eventid_item_keypress
* (needed for F1-Help (only when item selection activated))
* Nevertheless you have to provide their IDs again if you register
* additional events with SET_REGISTERED_EVENTS (see below).
* To do so, call first method GET_REGISTERED_EVENTS (this way,
* all already registered events remain registered, even your own):
call method g_alv_tree->get_registered_events
 importing events = lt_events.
* (If you do not these events will be deregistered!!!).
* You do not have to register events of the toolbar again.
*§4b. Frontend registration(ii): add additional event ids

SAP GUI hangs up - tree control

Hi,
I have written an ABAP program to display a report in tree format. This tree(designed using SAPGUI tree control) has close to 75K nodes. When I exit from this application(report), the SAPGUI hangs up. It takes about 25-30 minutes to exit this report program.
Further analysis tells me that it is only the front end process and NOT the runtime of the program. I am using Windows.
I am not sure how much this forum is relevant to this problem. But, any inputs on the reason for a slow performing GUI is appreciated.
Thanks,
Hema

There are some known performance issues with older patchlevels, since you neither mention, what GUI version you use and which patchlevel I would just recommend updating to 7.20 and the latest patchlevel and try again.
If that doesn't help the only thing left is to decrease the amount of data being sent to the frontend.

Is a tree control appropriate for this application?

I've been playing with the idea of designing a Visio-like application in LabView. (See my post from a year ago or so... Playing with the idea for a long time, I guess...)
My first approach was to use a flat array to hold all the objects that would be drawn. To draw them, I treated the flat array like a tree, adding new objects to the end, and traversing it carefully when drawing a page. (This page has this "group" object, which contains these other objects...)
Would the tree control be appropriate for this type of application? I don't necessarily need to show the user the tree. I would use it primarily for behind-the-scenes bookkeeping. Or is the tree primarily a GUI-oriented control?
Secondly, how can I relate items in the tree with the information I need to display on the canvas? For example, If I come across an object titled "panel\group_2\square_5" -- well, how do I use that to access all the properties of "square_5" (size, color, etc.)? When the tree is used for representing a directory structure, a tag named "c:\dir2\file5" is very convenient -- the computer knows what to do with that, and no massaging is needed. But what good is "panel\group_2\square_5"? Do I then perform a string "match pattern" of an array of tags, and use that index to the flat array of objects? Ugh, that doesn't seem very efficient.
Thanks!
Tom

Someone who's used OOP will undoubtedly jump in here and tell you this is an ideal case for OO, because they can easily have children and you can represent your tree structure in a logical fashion. Another approach would be to use variants. Since variants can have named attributes, and attributes are themselves variants, you can easily construct a tree representing all your objects. Each object might also have a "properties" attribute allowing you to access all the relevant properties of, for example, your square.

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 dynamic. I mean, there is a toolbar, whenever a pushbutton is clicked, depending on that the tree contents has to be changed.
If anybody had worked with CL_GUI_COLUMN_TREE control to get the data from database, depending upon the pushbutton selected in Toolbar, please paste the seudocode for it.

P.S: Helpful answers will be rewarded.

have you seen this demo program

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

Hi 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 R

Hi 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,
