create a property definition vi in LabVIEW class

[James.M · Accepted solution]

No problem. Personally, I don't use the property definition functionality very much, I just use data access VIs. There are some cases where it's helpful, but I haven't found a huge need. I kinda hope someone else comes in here and points out a huge use-case that I haven't thought of.

Generally, you don't need to do this manually. In the dialog for creating accessors (which you access by right clicking the class in the project window or specific items in the private data cluster) there is a checkbox for creating the accessors as properties which does this for you.

As for use cases, the most obvious one is if you want to set multiple fields in the same object - the code is much cleaner and easier to read if you can use a property node and extend it down. It can also save time on creating icons, which some people frown at. Of course, some people also frown at the whole concept of public accessors, instead preferring to have well defined VIs for every action done by the class.
