Overview

Description

Example Code Developed by James Baker - Amfax Ltd

The following community example demonstrates how to store and subsequently retrieve the hierarchy of a tree control.

The code uses a state machine with events to allow the user to; randomise the tree status, save the current status and restore a saved state.  It does this using the ActiveItemRowNumber and Open? properties.

 

Requirements

  • LabVIEW 2012 (or compatible)

 

Steps to Implement or Execute Code

  1. Run the VI.
  2. Click on Randomise Tree to randomise tree structure.
  3. Click on Save State to store and display current hierarchy.
  4. Click on Restore Sated to restore the previously saved hierarchy.
