Only View a Single Branch of a Tree Control at a Time

[BCho]

Overview: This VI demonstrates how to only have a single 'branch' to be expanded at a time.

---

Description:

When using tree controls, it is sometimes desirable to only see a single 'branch' or 'thread' of that tree at a time. By default, if you expand a branch in a tree control, it remains expanded until you close it. This VI demonstrates how to only have a single 'branch' to be expanded at a time. So, if you had one branch expanded and expanded a seperate branch, this VI programmatically closes all other branches.

---

Requirements: LabVIEW 2012 (or compatible). Hardware: none.

---

Steps to Implement or Execute Code:

1. Run the VI.
2. Expand the different branches of the 'Controlled Tree Control'.
3. Notice that if you expand a separate branch, the previously open branch closes.
4. Expand the different branches of the 'Default Tree Control'.
5. Notice that expanding one branch has no effect on other branches.
