The IDMCnrItem class represents container-specific items in a direct manipulation. Containers create objects of the IDMCnrItem class when either of the following occurs:
This class provides virtual functions that implement direct manipulation support for the container. You can derive item classes to support the direct manipulation of container items if the default Open Class Library support does not meet your requirements.
You can construct and destruct objects of this class.

Yes | Yes | Yes |
![]() |
public:
IDMCnrItem(const IDMItem::Handle& dragItem)
Use this constructor to construct IDMCnrItem objects for the target of a direct manipulation. It is called by the member function, IDMItemProviderFor::provideTargetItemFor, of the container's item provider for the container item class.
Windows | OS/2 | AIX |
Yes | Yes | Yes |
public:
IDMCnrItem( IContainerControl* container, IContainerObject* object, IDMSourceOperation* sourceOperation, const ISize& imageOffset )
Use this constructor to construct IDMCnrItem objects for the source of a direct manipulation. It is called by the member function, IDMCnrItem::generateSourceItems.
Windows | OS/2 | AIX |
Yes | Yes | Yes |
Use these members during the drop operation of a direct manipulation.
![]() |
public:
virtual bool targetDrop(IDMTargetDropEvent& event)
Implements container-item-specific rendering when the container item that
represents a container object is dropped on a target container. This function
adds the object into the target container. Derived classes should override
this function to insert the associated container object into the target
container if the default support does not meet your requirements.
Note:
IInvalidRequest | The drop cannot be completed. A source object must exist for this operation. |
Windows | OS/2 | AIX |
Yes | Yes | Yes |
Use these members to access and manipulate source items involved in a direct manipulation.
![]() |
public:
virtual unsigned long containerId() const
Returns the source container's ID.
Windows | OS/2 | AIX |
Yes | Yes | Yes |
![]() |
public:
static bool generateSourceItems( IDMSourceOperation* sourceOperation )
Generates container drag items that represent container objects selected in the source container. This function is called by the container's implementation of IDMItemProvider::provideSourceItems in the template class IDMItemProviderFor.
The default implementation of this function in this class creates
IDMCnrItem objects and adds them to the source operation.
If you use the IDMItemProviderFor template class and you have defined
a derived item class, you must implement IDMCnrItem::generateSourceItems
in your derived container item class. In your implementation, create one or
more objects of your derived container item class and call
IDMOperation::addItem
to add the objects to the source operation.
Note:

Yes | Yes | Yes |
![]() |
public:
virtual IContainerControl* sourceContainer() const
Returns a pointer to the source container.
Windows | OS/2 | AIX |
Yes | Yes | Yes |
