1.18.1.4 Working with Event Control

MATRIX VISION devices can generate Event notifications. An Event is a message that is sent to the host application
to notify it of the occurrence of an internal event. With "Setting -
you can handle these notifications.
At the moment, it is possible to handle
• Exposure End (= sensor's exposure end)
• Line 4 (= DigIn0) Rising Edge
• Line 5 (= DigIn1) Rising Edge
• Frame End (= the camera is ready for a new trigger)
1.18.1.4.1 Setting Event notifications using wxPropView
To activate the notifications, just
1. Select the Event via "Setting -
ExposureEnd .
2. Set the "Event Notification" to "On" .
Afterwards, it is possible to attach a custom callback that gets called whenever the property is modified. E.g. if you
want to attach a callback to the Frame ID after the exposure was finished, you have to
1. select "Setting -
Exposure End Frame ID",
2. right-click on the property, and
