The icon you use to represent your SubVI can tell you or other developers a lot about what the SubVI does without ever having to open the SubVI. Taking the time to create at least simple text VI icon is a requirement when sharing code between developers. The use of images in VI icons can also enhance their meaning when text can't be used because of length or in cases where code is shared across different spoken languages. National Instruments keeps an Icon Art Glossary to help developers who are less experienced making easy to recognize icons.
Editing the VI Icon
See Icon Editor.
|In LabVIEW 2011 the Connector Pane was changed to always be visible on the Front Panel window next to the VI Icon. LabVIEW 2010 and earlier only the Connector Pane or the VI Icon was visible at a time and they were toggled between via a right-click menu (Show Connector or Show Icon).|
|In LabVIEW 2012 the Icon API is released as Object-Oriented Classes. It allows for scripting Icons with access to Text, Glyph, and user levels.|
