Use captions on LabVIEW front panel objects to support VI localization without changing object names or recompiling callers. Captions also let you add detailed descriptions of objects without cluttering the block diagram.

Front panel objects can have captions in addition to owned labels. Use captions as the localizable text to localize the user interface of a VI without breaking the VI. Because an owned label affects the name of the object in LabVIEW code that references the object, localizing an owned name can break the VI.

In addition, you can use captions as a more descriptive object label than an owned label. Because the caption appears only in the front panel window, longer captions do not clutter the block diagram.

If you assign the object to a connector pane terminal, the caption appears in a tip strip when you use the Wiring tool to move the cursor over the terminal on the block diagram. The caption also appears next to the terminal in the Context Help window if you move the cursor over the connector pane or VI icon.

Note When the text of the caption changes, LabVIEW does not need to recompile the VI or its callers.
  1. To show or hide the caption, right-click the front panel object and select Visible Items » Caption.
  2. Edit the caption text.

You can also interact with and change captions programmatically.
