Input array to tree control and selected items - to output array

[Berezka]

Hi,

I'm new to LabVIEW and any help will be appreciated.

I would like to create VI with a tree control which receives an array of tests, displays this array as tree and returns an array of tests selected by user.

The input array is as following:

Module1 Test1

Module1 Test2

Module1 Test3

Module2 Test4

Module2 Test5

...

The tree should be as below:

+ Module1

           Test1

           Test2

           Test3

+ Module2

           Test4

           Test5

A user may select more than 1 test (using a mouse + Ctrl or Shift).

If a user selects a module (expanded or not expanded), then all tests of this module are selected (it's not must, but nice to have option). 

For example, a user selected Module1->Test1 and the whole Module2. The output array should be as following:

Module1 Test1

Module2 Test4

Module2 Test5

Can anyone please give an example of how to do this.

Thanks in advance.

For setting up the Tree you have to use property nodes and invoke nodes. This can become a bit tricky. Selecting mode for items can be configured in the context menu. For start see example VI.

For the desired extended you need to check whether a parent item or all child items are selected. To start this process you can detect the events generated by the Tree control. Tip: use the child tags to detect which element belong to which group. But the rest will be your job.

Example is in LV 8.6

Hi,

If I wanted to create a tree control from a 2D array of strings containing data such as:

parent1 child 1

parent1 child 2

parent1 child 3

parent2 child 1

parent2 child 2

parent2 child 3

etc...

I basically have over 500 "child" entries and about 20 different "parent" entries I will be getting the list from a sql server and bringing it into LV as a 2D string array, is there a way to take this array and convert it into a tree control?

Thanks In advance

Well, I believe that I may have solved my own problem. If interested, here is an example of what I did.

The vi will run properyly provided the size of the "ParentColumn"  and the "#ChildperParent" array are same... or else you may end up with some issues

I have a similar problem which has been bugging me for several days..  It will be greatly appreciated if you can re-post the example in Labview 8.5.   Thanks

Here's that example in 8.5:
