AnnGroupObject Class

Summary

This class provides support for creating and managing annotation group objects.

Syntax

C++

public class AnnGroupObject : Leadtools.Windows.Annotations.AnnRectangleObject, Leadtools.Windows.Annotations.IAnnGroup, Leadtools.Windows.Annotations.IAnnHeader, Leadtools.Windows.Annotations.IAnnObject, Leadtools.Windows.Annotations.IAnnRectangle

Public Class AnnGroupObject  
   Inherits Leadtools.Windows.Annotations.AnnRectangleObject 
   Implements Leadtools.Windows.Annotations.IAnnGroup, Leadtools.Windows.Annotations.IAnnHeader, Leadtools.Windows.Annotations.IAnnObject, Leadtools.Windows.Annotations.IAnnRectangle

public ref class AnnGroupObject : public Leadtools.Windows.Annotations.AnnRectangleObject, Leadtools.Windows.Annotations.IAnnGroup, Leadtools.Windows.Annotations.IAnnHeader, Leadtools.Windows.Annotations.IAnnObject, Leadtools.Windows.Annotations.IAnnRectangle

Remarks

The annotation group object contains a collection of annotation objects from any class that is derived from theAnnObject class. This collection of objects can be treated as one while they are in a group. An annotation object can be in either a container or a group but not both at the same time. For more information about grouping and ungrouping, refer to Grouping and Ungrouping WPF Annotation Objects.

Example

This example moves all the objects from a container into a new group object.
