How to assign Decoration name or number to each decoration on Front panel?

Hi Everyone,

How to assign Decoration name or number to each decoration on Control panel?

What exactly do you mean by "decoration"? You already have the Control Label. You can customize it through the controls at the top of the window. Is this what you want?

[pincpanter]

Don't use free labels associated to a specific control. Right-click on the control, select Visible Items -> Caption from the context menu.

Then, you can freely customize Caption font, color and so on. Furthermore, you will be able to change them by means of the control properties.

No. I mean if we want to program each decoration to visible or hide, we need to know decoration name or decoration ID to identify in program for that decoration will visible or hide correct object.

Because if we programming with 100+ decoration objects we need to assign each decoration name or ID for easy to manage in the program.

Then your example vi is not so good, because it contains only free labels.

Working with decorations is not a very easy task; you may use the UID property to identify them, but this number is assigned by the compiler, so you need to annotate the UID of each decoration you create.

Just to reiterate what pincpanther said: Use Captions or labels as you have easy access to those through the properties.

If you do want (and you really don't need to) use decorations, the only way I know how to do this is to get back a list of references and know where in the array they are:

So, that mean we cannot identify by our self need to follow number from compiler assigned only?

And the number from compiler assigned only one way to know is use index to check which decoration is visible/not visible?

In the past I had some main vis with a lot of decorations. At that time (LV 7.1) decorations had less properties, so I was forced to identify them by means of their position in the Decorations array. This is far from ideal, because the position will change depending on the decoration Z-order.

So, I wrote a small vi to find decorations in a given vi. You need to load both vi's, set the right vi name in Highlight decorations.vi, then run it.

As you navigate through the array, you will see the corresponding decoration highlighted in the other vi's Front Panel.

I attach a modified version, adding the UID as additional info.

Try these.

Obviously, you can use their index, if there are just a few, or if they are all the same.

Each decoration (each object actually) has a UID. These will not usually change, I think they stay linked to an object until it's deleted. You can use those.

The other way is to tag the objects. Each object can be tagged, including decorations. Those posted VI's use tags to attach a label to decorations.

Sadly the label that can be given from the UI has never worked... There are idea exchange posts about that (like this one) but apparently nobody cares...
