LabVIEW is a dataflow programming environment where the flow of data determines the execution order of block diagram elements. Event-driven programming features extend the LabVIEW dataflow environment to allow the user's direct interaction with the front panel and other asynchronous activity to further influence block diagram execution.

Note   Event-driven programming features are available only in the LabVIEW Full and Professional Development Systems. You can run a VI built with these features in the LabVIEW Base Package, but you cannot reconfigure the event-handling components.
