Vector Notification Messages

When calling vector class library functions, notification messages are sent through the LVectorBase::StartChanging and LVectorBase::EndChanging member functions. These functions are called before and after executing the function that changes the vector. By overriding the virtual functions, you can do other processing, or even halt the operation. For a complete list of messages, please refer to Bitmap and Vector Change Notifications and Notification Categories

The following methods are used in conjunction with vector notification messages:

LVectorBase::StartChanging

LVectorBase::EndChanging

LVectorBase::EnableChangeNotification

LVectorBase::IsChangeNotificationEnabled

LVectorBase::EnableAlwaysEndNotification

LVectorBase::IsAlwaysEndNotification
