Use the Groups property to access the control's groups collection. Use the Add method property to add new groups to the control. Use the AddItem method to add new items to the group. Use the BeginUpdate and EndUpdate methods to maintain performance while adding new groups or new items. Use the Font property to specify the control's font. Use the GroupHeight property to specify the height of the captions for all groups. Use the ItemHeight property to specify height of the items in the group's list.

            .AddItem "Item 2"

The following C++ sample adds two groups and two items to each group:

#include "Item.h"

COleVariant vtMissing; V_VT( &vtMissing ) = VT_ERROR;
m_listbar.BeginUpdate();
CGroups groups = m_listbar.GetGroups();
CGroup group1 = groups.Add( "Group 1" );
group1.AddItem( "Item 1", vtMissing );
group1.AddItem( "Item 2", vtMissing );
CGroup group2 = groups.Add( "Group 2" );
group2.AddItem( "Item 1", vtMissing );
group2.AddItem( "Item 2", vtMissing );
m_listbar.EndUpdate();
