delete programmatically a an item of a string ring control

[olivier66]

Hi,
I'd like to know what's is the property node wich can give the value of the digital display, because I have a ring control and I need to allow the user to add or remove some of the items
I succed to do it for adding but not for deleting, and I think it is because I cannot find a property node on the value of the digital display, the property node value only gives the value of the current item.
I attached a capture of my program.

Thanks

Olivier

Hi Olivier,

using property node 'Strings and values' you can read and set the strings of the ring control AND their corresponding value! Make up an array with needed values and wire it to this property node.

In your block diagram you just add (by 'build array') new items to the ring control! You have to look for the selected item (via it's value) and then delete it from the 'strings and values' array!

Hi,
Could you give me an example of what you are saying "You have to look for the selected item (via it's value) and then delete it from the 'strings and values' array!"
because I don't understand how I delete the item

Thanks

Hi Olivier,

that's easy:

But remember: there's no error checking in the example...
