Event Sources

Last Modified: August 9, 2019

You can configure the Event Structure to handle events from any supported source.

  • User Interface—mouse clicks, key presses, and so on.
  • External I/O—hardware timers or triggers that signal when acquisition completes or when an error condition occurs.
  • Programmatically generated events—events triggered by diagram code, without any user interaction.
Each event is associated with a control on the panel of the VI, the panel window of the VI, a pane of the VI, or the application.

The application generates events for a VI only while that VI runs or when another running VI calls that VI as a subVI.
