Detailed Description#

class Pylon::CActionTriggerConfiguration;

Changes the configuration of the camera so that it is triggered by the first available action command.

This configuration enables the frame start trigger and disables all other trigger types. As trigger source the first available action command is selected, i.e., the camera will be triggered by action commands issued by the application.

In contrast to using the software trigger triggering with action commands allows to trigger multiple cameras simultaneously.

Either register this configuration as an Instant Camera's event handler or apply the configuration to the node map of an opened pylon device using one of the ApplyConfiguration methods.

The CActionTriggerConfiguration is provided as header-only file. The code can be copied and modified for creating own configuration classes.

function OnAttach#

inline virtual void OnAttach(
    CInstantCamera & camera
)

This method is called before a Pylon Device (Pylon::IPylonDevice) is attached by calling the Instant Camera object's Attach() method.

Parameters:

• camera The source of the call.

Error Safety:

C++ exceptions from this call will be caught and ignored. All event handlers are notified.

Thread Safety:

This method is called inside the lock of the camera object.

This method can not be used for detecting that a camera device has been attached to the PC. The camera's Attach() method must not be called from here or from subsequent calls to avoid infinite recursion.

function OnAttached#

inline virtual void OnAttached(

C++ exceptions from this call will be caught and ignored. All event handlers are notified.

Thread Safety:

This method is called inside the lock of the camera object.

This method can not be used for detecting that a camera device has been attached to the PC. The camera's Attach() method must not be called from here or from subsequent calls to avoid infinite recursion.

Camera Close must not be called from here or from subsequent calls to avoid infinite recursion.

function OnClosed#

inline virtual void OnClosed(
    CInstantCamera & camera
)

This method is called after the attached Pylon Device has been closed.

Parameters:

function OnGrabStart#

inline virtual void OnGrabStart(
    CInstantCamera & camera
)

This method is called before a grab session is started.

Parameters:

• camera The source of the call.

Error Safety:

Exceptions from this call will propagate through. The notification of event handlers stops when an exception is triggered.

Thread Safety:

This method is called inside the lock of the camera object.

Camera StartGrabbing must not be called from here or from subsequent calls to avoid infinite recursion.

function OnGrabStarted#

inline virtual void OnGrabStarted(
    CInstantCamera & camera
)

This method is called after a grab session has been started.
