Member Data Documentation

◆ eventNotification

readonly mv.impact.acquire.PropertyI64 eventNotification = new mv.impact.acquire.PropertyI64()

An enumerated integer property. Activate or deactivate the notification to the host application of the occurrence of the selected Event.

Activate or deactivate the notification to the host application of the occurrence of the selected Event.

The following string values might be valid for this feature:

  • Off (Display string: 'Off'): The selected Event notification is disabled.
  • On (Display string: 'On'): The selected Event notification is enabled.
  • Once (Display string: 'Once'): The selected Event notification is enabled for one event then return to Off state.
  • GigEVisionEvent (Display string: 'Gig E Vision Event')
Note
Depending on the device some of these values might not be supported and especially when working with third party devices there might be custom values which are not listed here. To get a complete and reliable list of supported values at runtime an application should therefore call mv.impact.acquire.EnumPropertyI<T>.listOfValidStrings() or one of the other functions dealing with translation dictionaries for enumerated properties.
