Numeric cell in Tree control ?

Hi y'all !
I'd like to have numeric input cells in my TREE CONTROL. I can see the types string, ring, combo box, etc. ... but NUMERIC is not included.
I'm using CVI 2012.
Is there an alternative or does anyone know at least why it is not supported ?
Thanks!

Hi carolynturnell,
Indeed cell types included in a tree control are String,Ring, ComboBox, CheckBox, ColorPicker and HorizontalBar.
Tree controls are used to view a hierarchical list of items.
Why do you want to display Numeric/use tree control ?

Renaming the text of a cell in tree control during run time

Hello all,
Actually i am stuck up at one point.In the picture of front panel i attached,there is a tree control and two buttons (re,stop).when i press the rename button,i want the selected cell in the tree control to be focussed and when i enter some text through the key board the cell should be renamed.Can anybody suggest me how to do this?

LV7 Tree control Modify Left Cell String

Is it possible to modify the "Left Cell String" of a tree node - I can't find the appropriate method or property to do this.
Cheers,
Wayne

Pleeeeaaaasssseee don't use stacked sequence structures. Use flat sequence structures if you need to. And even then in your code you can eliminate most of them by using property nodes and error wires appropriately..
Look at https://decibel.ni.com/content/docs/DOC-4519. Use Defer Panel updates to speed up the execution when updating multiple tree control properties.
See attached modified VI.

Tree Control Property Node for Accessing "Child Text" String Array

When adding items to a tree control using the EditTreeItems invoke nodes, the inputs include "Child Tag", "Item Indent", "Child Only?", "Glyph Index", "Child Text", and "Left Cell String" as can be seen in this screenshot.
There are property nodes for the tree control for accessing each of these elements, except for the "Child Text", which is an array of strings. It is possible to access this data as outlined in this forum post, but this method is somewhat involved and round about.
I suggest that a property for the Tree class be created to access the Child Text array directly.

The work around only works if you do not have an empty string element some where in the middle.
At lest could the "Active Celltring Property" read return an error when you have gone beyond the end of the array.

How to get access to Row Data (Child Text) in a Tree Control Pragmatically?

In LabVIEW 2010, I have entered Row Data into a Tree Control pragmatically using the Add Item method and providing the Child Text array and the Child Tag for the Row. When a Row in the Tree Control is selected, I can get the Row Tag in the Value Property of the Tree. But how do I access the Child Text array data when the Row is selected? I can't seem to find a Tree Control Property or Method that will return that data back again.
What I am trying to do is: once a Row in a Tree is selected and a button is pushed, if the Row Tag is valid, I want to transfer all of the Row data into another similarly formatted Tree. To do that I need the Row Data for the Tree and Row that was selected. I can not find a way to get access to this Row Data after it has been entered into the Tree.
Can anyone tell me how to pragmatically access the Child Text or Row Data in a Tree Control from a selected Row in the Tree? I have the Tag for the Row, but how do I access the data?
Thanks for your assistance.

Go to Solution.

As mentioned in the posting here, you can use the Active Item:Tag property to set the item to which subsequent property changes apply. This includes pulling the Active Celltring values out in a for loop as you increment the Active Cell:Active Column Number to get the row's Child Text data programmatically as I was originally wanting to do.
Note that wiring a 0 to the ActiveColNum property and reading the String value will return the tree item's visible name (in column 0), but not the unique item Tag (which is somewhat intangible after its creation). Therefore, I save the unique item tag when I add the item to the tree control (the output of the Add Item invoke node) and store it as a separate column of the Child Text array and place it out of sight in the tree control so I have access to it later. It might be useful, it might not.
I find the tree control totally non-intuitive and not well explained anywhere, but that's how a lot of LabVIEW coding is I guess. Play with it long enough and you become an expert. I had to learn the hard way, but I hope this helps someone else.

Save Labview tree Control to file and Load from file

I want to save all of the information from my Labview (8.2) tree control to a file and be able to read it back from a file and re-populate the tree control. I am using different symbols as well as multiple columns and level of children in my control. Does anyone have any suggestions on how to do this?
Thanks
Steve M.

Hi Steve,
I found a DF that talks about saving the tree to a spreadsheet file and have included it in this message. To get items from the tree control, you have to use open up the tree and remove all of the items off of that tree, while still preserving the heirarchy of the tree. The indent level property node will preserve the heirarchy of the tree and from there you can get the item tag and cell string.
To transfer the file to a tree, you will then need to read the file and insert items into the tree corresponding to the heirarchy. I have also found a tutorial on how to traverse tree controls.
I hope this helps.

Flex Using Tree Control in item renderer(Url Navigate)?

HI All.,
Iam Using flex 3 using tree control in item renderer to click haschildren label to be navigate url is possible ?.
Any one help me.....
Thanks in Advance......

You can do this by writing the item's tag to the ActiveItemTag property, the column number you're intersted in to the ActiveColNum property and reading the Cell String Property.

How to add popupMenu to Tree control in BSP

Hello,
I need to attach a popupMenu HTMLB control to htmlb:tree control in BSP (something like a hooverMenu in EP).
Any ideas?
Thanks,
Yan

i'm using this code:
jTable1.addMouseListener(new MouseAdapter() {
public void mousePressed(MouseEvent e) {
if (e.isPopupTrigger()) {
int row = jTable1.rowAtPoint(e.getPoint());
int col = jTable1.columnAtPoint(e.getPoint());
pop.show(e.getComponent(), e.getX(), e.getY());
public void mouseReleased(MouseEvent e) {
if (e.isPopupTrigger()) {
int sel = jTable1.rowAtPoint(e.getPoint());
int col = jTable1.columnAtPoint(e.getPoint());
pop.show(e.getComponent(), e.getX(), e.getY());
in the specified cell ( the cell i clicked) should be a vector with values. How can i get this vector and add the values to the popupMenu??
thanks

Embedding Tree control in TableView

Hi all,
I want to create a table which rows can be collapsed, looks like a tree embedded into a table.
But we do not know how to implement it using Portal Applications. Can anyone send an example to do it?
If I use CellRenderer to render tree control,After expanding the tree node,the subnodes are displayed in the same cell.But what I need is ,on expansion of tree the rows also should be expanded and collapsed accordingly.
Thanks in Advance,
Santhosh

Hi Santhosh,
Actually there is no need to use div tag. I am giving a sample code below. Try it and make the necessary modifications.
<html>
     <head>
          <title>
               Expand/Collapse
          </title>
          <script language='javascript'>
               function toggle(divid)
                    obj=document.getElementById(divid);
                    visible=(obj.style.display!="none");
                    if(visible)
                         obj.style.display="none";
                    else
                         obj.style.display="block";
          </script>
     </head>
     <body>
          <table border=1>
               <tr>
                    <td><a href=javascript:toggle("first")>First</a></td>
               </tr>
               <tr id="first" style="display: none;">
                    <td><b>This is the first text</b></td>
               </tr>
               <tr>
                    <td><a href=javascript:toggle("second")>Second</a></td>
               </tr>
               <tr id="second" style="display: none;">
                    <td><b>This is the second text</b></td>
               </tr>
          </table>
     </body>
</html>
Hope this solves your problem.

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.

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!

Tree control column question - Hot/Indicator

Is it possible to have some columns in a tree control be hot (edittable), and others as indicators (not edittable)? It seems as if all the columns (except for the "0th" first column) must be either all hot or all indicators. I also looked into the Cell attributes and there is no way to make indiviidual cells as either hot or indicators either (like Table controls).
I did notice that items can be dimmed using tho ATTR_CELL_DIMMED attribute, which gives a behaviour similar to what I'm looking for (user can't edit the cell value) but also gives the cell a greyed out appearance. I tried manually setting the appearance of the cell back to what I would like (ie ATTR_LABEL_TEXT to black) but naturally this didn't have an effect. Any ideas? Thanks.

Go to Solution.

You can pick and choose which columns and cells you'd like to edit using the tree's callback function if you have CVI 2009 or later. You can use ATTR_TREE_RUN_STATE and ATTR_TREE_EDITABLECELLS inside EVENT_LEFT_CLICK (and probably EVENT_LEFT_DOUBLE_CLICK too) to accomplish this. I'm attaching a simple project with a tree that you can edit the first column with a double click, the 2nd column with a single click and you can't change the data in the 3rd column at all. You could even specify individual cells you to make editable if that's what you wanted to do.

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.
