Issue Details

  • I have a text ring (or enum) that has elements that are more than 255 characters of length (For example a very long file path). I am able to add them correctly to the text ring (or enum), but the control at the front panel only shows 255 characters per element, so I can't see the full name of the element.
  • Can I change the number of displayed characters to be higher?
  • For example, if the enum element has the following string for the first element:
Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation  ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate

Then, the enum control only shows the first 255 characters  of the string:


LabVIEW text ring & enum front panel controls displays a maximum of 255 characters per each element of the list. If this size is not enough to differentiate between two elements of the list, then you should consider the following alternatives:
  1. To shrink the text so it can fit within the 255 characters limit.
  2. To change the format of the text so the text ring or enum can show enough information to differentiate between two or more elements.
