Add Variant constant to the Cluster, Class, & Variant function palette

[FabiolaDelaCueva]

Every time I need a variant constant, I have to:

1) Pick any function from the Cluster, Class & Variant functions palette>>Variant

2) Place it in block diagram and right click>>create>>constant

3) Delete function.

I believe the variant constant should be in that palette.

I did a search in the functions palette for "variant constant" and it is not there.

Please add the variant constant to the Cluster, Class & Variant>>Variant function palette 🙂

Thanks,

What exactly is a variant constant?  (Though after typing it, it seems like an oxymoron.)  Since a variant is essentially a datatype that can contain any kind of information, what data or default datatype should that variant contain when you drop it on the block diagram as a constant?

Can you give an instance where you needed to use a variant constant?

(OK, I just though of one.  When defining a datatype to be fed into something else like an obtain queue.)

Fab,

Another method I use to get a variant constant is to create a control from the Modern >> Variant & Class palette, then change it to a constant.  This may be a little faster your method of creating a constant from a variant function.

I agree that it would be very nice to have this on the functions palette.  I often need an empty variant constant when I use variant attributes.

If you use the OpenG libraries, the Variant palette contains a constant that can be dropped (used to be referred to as a merge vi)

Returning to this publication. I think the creation of the Variant constant, is one of the key steps in using a design pattern (Producer / Consumer) for example, so this idea should be taken into account.
