Property Value

The AnnGroupObject that contains this AnnObject.

An AnnObject can be part of one AnnGroupObject only at any given time.

When adding or removing objects to or from a group, you do not need to manually set this property to the container value: this operation is performed internally by the LEADTOOLS annotation toolkit. However, you can check the value of this property to determine the group (if any) to which a certain object currently belongs.

Public Sub AnnObject_Group()
   ' add an object to the first container
   Dim line As AnnLineObject = New AnnLineObject()
   line.Name = "Line1"
   ShowGroupAndContainer(line)

   ' add it to a group
   Dim group As AnnGroupObject = New AnnGroupObject()
   group.Name = "Group1"
   group.Objects.Add(line)

   ShowGroupAndContainer(line)

   ' add the group to a container
   Dim container As AnnContainer = New AnnContainer()
   container.Name = "Container1"
   container.Objects.Add(group)
