LVectorGroup

Description

The LVectorGroup class is used in conjunction with the main vector class LVectorBase, the vector layer class LVectorLayer, and the vector object class LVectorObject. This class contains the functionality for dealing with vector groups. This class contains functions for the following:

• Enumerating the vector objects in a vector group
• Removing the vector objects in a vector group
• Copying a vector group to another vector
• Getting information about a vector group
• Adding objects to a vector group
• Returning count of objects in a vector group

When calling some functions of the LVectorGroup class, the associated vector data is changed. To be notified of these changes, you can override the LVectorBase::StartChanging and LVectorBase::EndChanging functions. For more information, refer to Bitmap and Vector Change Notifications and Notification Categories.

If you derive a class from LVectorBase, the macros defined in Wrapper Macros may be helpful.

Required Libraries

• You must load all required libraries using LBase::LoadLibraries before using the classes.
• LVKRN
• For a listing of the exact DLLs and Libraries needed, based on the toolkit version, refer to Files To Be Included With Your Application.
