Event Sources

    Last Modified: August 6, 2018

    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.
