Decoration labels

[pincpanter]

If I show a decoration's Object Property dialog, a field named "Label" appears where I can type text in (LV2011). There's also a "Visible" check box above it.

However, the check box keeps to be disabled even if I put some text in the label, furthermore the text is not retained when I close the dialog.

On the other side, a decoration property node will not show any "Label" item.

What this field is good for?

Probably nothing. The Decoration class, if memory serves, inherits from Generic, which does not have a Label property. I'm guessing this is just an oversight in the dialog where no one thought to hide that field. I didn't even notice that you can open the properties dialog for a decoration.

That's a pity. I did hope to use that Label to identify decorations. Indexing the Decorations[] array it's uncomfortable and prone to errors.

Thanks for the links. In the meantime, I have written a "decoration managing" vi that may be useful to show decoration indexes and easily hide/show them.

BTW: for a label decoration the Label field matches the decoration text.

Just put a floating label next to the decoration, then group them.

What I would like to do is to show/hide and possibly move decoration programmatically. For this, I need to know the position (index) of each decoration in the Decorations[] reference array.

That index may change when you move objects forward or backward in the FP. Hence the need of a method to find the index quickly.

I would assume the index doesn't change, but i haven't tested it. Z-property doesn't change index of controls, to my knowledge, only tab-order.

The index does change indeed following the Z order. You may check it quickly using my vi.

Hmm, what if you turn the decoration references to Variants and add use Set Attribute? Then you have something to search for.
