ring question

[Alron]

Hi,
1.Can I programmatically enable an item in a ring , after it has been
disabled ?
2. Can I programmatically select several ring items?

Thanks, Alexander.

Hi Alexander,

1. Yes. When you can disable it, then you can enable it too...
2. No. Only one selected item...

Hi Alexander

On your block diagram you can create a property node for the diabled nature of your ring control. If you change this node to write and then input an integer array with the elements that you want to disable then you can programaticaly control what is disabled and what isn't.

If your not sure about how to do this then tell me and I will write a short sample code for you.

best regards

If you still want to programatically select several ring items, code in its mouse down event such that on every selection you update the ring's text.text to a string array, so that you can get a list of selected items when the user has finished the operation.

But how keep several items selection colored (marked) ?

Hi,
I have tried with a property node, but could only desable an item, so any
example (Labview 8.0) will be appreciable.
Thanks, Alexander.

Perhaps you should consider using a Listbox instead. This will allow you to easily select multiple items without doing a lot of dancing around with code.

You would use the "disabledItems[]" property and give it an array of indices. To enable all, wire an empty array.

You should consider using a listbox instead so as to color several items.

But that too will not enable you to change the color of each item to be different. It ll inherit the OS settings.

I don't think the user isn't trying to use different colors for each selected item. They just want to be able to select multiple items and is using the term "colored" to indicate they're selected.
