Edit Tree Control Question, specific cells

• Question of tree control column - hot/indicator

  Is it possible to have some columns in a tree control will be hot (Edition) and others as indicators (no parameter)?  It seems as if all columns (except the first column "0th") must be all hot or all indicators.  I also looked in the attributes of the cell, and there is no way to make cells either as hot or indicators indiviidual either (like Table controls).

  I noticed that the elements can be mitigated using tho attribute ATTR_CELL_DIMMED, which gives a behavior similar to what I'm looking for (the user cannot change the value of the cell), but also gives the cell a greyed look.  I tried to manually adjust the appearance of the cell back to what I would (IE ATTR_LABEL_TEXT to black), but of course, it didn't have an effect.  Any ideas?  Thank you.

  You can choose the columns and cells you want to change using the tree callback function, if you have a CVI 2009 or later. You can use ATTR_TREE_RUN_STATE and ATTR_TREE_EDITABLECELLS inside the EVENT_LEFT_CLICK (and probably EVENT_LEFT_DOUBLE_CLICK too) to achieve this. I enclose a simple project with a tree that you can edit the first column of a double-click, the 2nd column with a single click and you can not change the data in column 3 at all. You can even specify individual cells make you it editable if that's what you wanted to do.

• Extraction of a particular tree in Front pannel cell value

  Hi all

  I would like to make my problem in a simple way

  I have a structure of tree on the front panel with 2 columns and 20 rows. I filled all the attributes of a camera in this tree.  First coloumn contains the name of the attributes of the camera, second coloumn is their values. I want to use the value of the attribute 'image size' in my program to make the initial memory allocation.

  How can I extract a particular tree structure attribute value? I referred the thread below, but he described to extract the line on 'ActiveIteamTag' (I don't have this notion).

  http://forums.NI.com/T5/LabVIEW/reading-second-column-in-tree-control/TD-p/421668

  can we have a simple solution to extract a value of tree?

  Hello

  No, of course, you don't have to enter this advanced programming.

  The tree control is powerful enough and not always easy to deal with.

  To return to your original question, in order to be able to read a specific attribute of the tree in the example, you reference, here's what you can do:

  

  One thing that is a bit tricky with trees is that you can have several times the same value of the cell (string displayed) but each 'line' of the tree has a single tag, in this example the screw that fill the tree using some kind of 'course' with ': ' as the separator.

  Hope this helps

• Tree control: how to change an element

  I know how to create a tree. It's very pretty.

  The next natural step is to edit something:

  For this example, let's say I have a level superior element called 'Rob' and he has two children "Nora" and "Caleb". The names are the values of the "chain of cell to the left" and tags, we will tell you. Nora is 4 years old, Caleb is 1, so when I create the tree I make tables 1 d of these values and put them in "text of the child".

  Now, I leave the program going until the beginning of November and the day of the anniversary of Nora I want to programmatically change the '4' to a '5 '.

  There are methods add an element and remove the element, but no method of Edit Item.

  Call me puzzled. This happens on the list of 10 things.

  Meanwhile, someone would have an answer to my quandry? Thanks in advance.

  Follow-up: When I invoke add something, I have a string output. What is c? The tag assigned, I guess? Aid does not mention it. It's a trick question, because I don't actually think it is possible, given the add part function works when you call it twice in a row with the same entries.

  P.S. "you're a jerk" is certainly a reasonable response to this post.

  I played a bit with tree controls. You're right, they are not really intuitive.

  Here is an example of one that I go fairly reliable... http://decibel.NI.com/content/servlet/JiveServlet/download/3968-1-4990/m3u%20playlist%20generator.LL...

  I think you need to do is on the tag active that you want to change (property node) "Active: element tag.

  Then you can write to the property "Active celltring '.

• How to get the position of a ring in a tree control?

  Okay, this is probably a stupid question, but how can we get the position of a ring within 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 do you get the position once the user has changed the control?  I found the functions GetTreeCellRingIndexFromValue() and GetTreeCellRingValueFromIndex(), but I have not found a way to get the Index or the value of the ring (I'm looking for is the index, but if I can get the value I can from there).  Thanks in advance!

  You can get the value of the cell in the tree of GetTreeCellAttribute (ATTR_LABEL_TEXT). Then, as you noted, you can use GetTreeCellRingIndexFromValue() to get the index.

  I hope this helps.

• OBI10G - Format a specific cell in a pivot table dynamic

  Hello
  
  I have a question about the format of the specific cells in a PivotTable. Take a look at this image:
  
  http://ImageShack.us/f/405/PivotTable.jpg/
  
  This PivotTable is composed of 3 combined applications. The last 2 lines where you can read 'Total Mensal' and 'Total annual' built 'manually '. My question is: if I want to format only these 2 cells ('Total Mensal' and 'Total annual', let's say I want to have the text in bold) question: How can I format only these 2 cells?
  
  I know that with CSS, I can create my own classes, but that would apply to all column "Origem" if I'm not mistaken. So I guess I have to use javascript to change these cells in particular or is there another way? And if I have to use javascript are some examples that I can see how to use it? I have not touched in javascript for some time now, so I'm really rusty and have some sort of example of what I want to do would really help.
  
  Thank you

  Hello

  Here assuming that 'Total Mensal' and "Total annual" are columns of static text and they are part of the "Origem" column, then you can try below:

  -Change the format of data in the column Origem from plain text to HTML.
  -Change the static of "Total Mensal" to "Total Mensal < /b > < b >.
  -Change the static of 'Total annual' to 'Total annual < /b > < b >'

  Now, these two static texts displayed in "BOLD".

  Thank you

• Sparks tree control: ETA?

  This question is for the SDK team:

  Is there an ETA for a spark-based tree control? The project that I'm trying is heavily based on the tree control. In the last 6 months I've tweaked and customize the control tree 60 ways to Sunday. It has exposed a number of problems and bugs in the control, and by all accounts, it seems that Adobe will not address these in the future.

  Every day I fight these issues with the tree. Simple stuff can be very difficult.

  I propose that the project be migrated to Flex 4, for many reasons. However, the question has been raised by the stakeholders, who are aware of the issues that we have struggled on the current control, is when the Spark version will be released. I don't have an answer.

  Thank you

  It won't in 4.5, probably the release after.

• Count specific cells that contain '1' or 'G '.

  Hello world

  I have a sheet of numbers with the data presented as '0', ' / ', '1' or 'G '. I would like a formula that counts the combined total of '1' and 'G' entires in each column, but I'm having some trouble. I used the COUNTIF function with a range elsewhere in the sheet to count the number of entries "1". But this time I need to count the number of '1' or 'G' entires in some cells (each third cell of a range), so my previous COUNTIF(cell:cell) is not going to work.

  You can use COUNTIF with multiple values (in my case '1' and 'G') for specific cells, instead of a beach? Any help would be much appreciated. Thanks in advance.

  I should add that I am looking to count the combined total of the '1' and 'G' entires in a number of cells. Don't know if I was clear above!

• Tree control mode: Returns a validation event when the NORMAL value

  CVI 2013: I am writing a software to change the command tree modes based on the user's selection. I noticed that when the command is set to NORMAL, I got a "EVENT_COMMIT". Just for reference, I am using a custom control - group of Radio buttons, but the bug (I'm assuming that) is in the tree control are I forgot something?

  An application of Corrective Action (CAR) has been filed for this behavior. His number is 578618. You can monitor the condition of this CAR by checking the notes Readme or release new versions and checking the bug fixes section.

• chain of the evil tree control

  Hello

  I have problems with a tree control. Watch my vi, select a line and start the vi. Now, select a line after another and look at the values.

  The tag is fair, but the string is incorrect or is not available.

  Is this a bug. Or what is the problem?

  Greetings

  Schwede

  Schwede,

  You must define the number of the current column to 0 once at the beginning (before entering the loop).

  Some time would have been nice also...

  hope this helps,

• How do you get the tag line in last-one click on a tree control?

  The API for tree controls is infuriatingly obtuse.

  In response to an event initiated by the tree control, I need to query the currently selected item in the tree and get his tag, so I can handle the element and its children. How this is done? I found the method of 'Set the tag', but there is no Tag «get» In fact, the only way to get the tag of any element seems to be through the 'Point to the column line' method, which takes a pair of coordinates entry component! It's confusing!

  Oh hell. Value of tree is the tag of the element currently selected. It's so easy that I never thought to look there for it, given the complexity of almost all other actions in the API.

  * sigh *.
