Openg Get Cluster Element Names__ogtk.vi

[yanzhanglin]

it seems doesn't work if cluster contain map or set

[paul_a_cardinale]

Check if the elements in your cluster constants have non-null labels.

map cann‘t be null？？？

I don't have the OpenG Toolkit, but when I use the built-in functions, it works for me.

Look inside the OpenG code.  See if you can find where things are going wrong.

As far as I know, the OpenG VIs are older than maps and sets and therefore cannot handle maps and sets.

I don't know how to fix

This is true, but on the other hand the Label.Text property is rather basic, implemented in the Control class.

And Maps are undoubtedly controls.

Hi,

This question has been asked and resolved many times already like in this post:

Simply use the VIs present in the Data Type Parsing palette:

@ pincpanter

Not that simple, if you look at the implementation of "Get Data Name from TD__ogtk.vi", the Pascal string containing the name of the data starts at different offsets in the type descriptor, depending on the data type. The Map/Set case is clearly not implemented (at least in the last OpenG version for LV2021, which I have tested).

Raphaël.
