• 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,

• Edit Tree Control Question, specific cells

  Hello

  I have a question on the modification of tree controls.

  I have played around with the properties and to date have not thought to it. That's what I'm doing:

  I have a tree with multi-column control.

  The columns are essentially: name, Description, value 1 and value 2

  I want to do is be able to select the value 1 and value 2 and change them individually on each line.

  I want to be able to change the name and Description.

  What I was able to do so far is the editable table and every time I get the string in the active cell regardless of the cell that I click in returns always the value of the first column.

  I had this problem by making my changes of value by calling a pop-up box and change the values, but I would rather simplify it by editing the tree.

  I can't give my real code, but if it helps I can make an example facsimile...

  Here's a suggestion:

  -tour of the edition on the tree cell

  -When the clicks double user on a cell, if the column index is 2 or 3 then set the position of the appropriate cell editing

  see this: (in this example, I'm not filtering the column index, but I'm sure that you'll be able to add this feature)

  

• 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.

• 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.

  OK, so I'm unable to set up a tree control the way I want to...

  I have a 2D channels table that looks something like this [1, 1, 1, 2, 2] row 0

  For each unique element in row 0, a parent tag must be created and an item added to the tree of the same name as the parent tag.

  As I was mountain BIKING in the train a simple useful optimization appeared to me, saving a lot of redundant comparisons: use the iterator from the most to the loop as long as the start of the next loop index.  In addition, loop if the array is empty (you would think that it's automatic, but it turns out that an autoindexed for loop with an entry in a table of 4 x 0 will be still go 4 times, at least with the highlight performance enabled).  Here is an excerpt showing the change, which was not tested, but I think it's good:

  

• 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.
