### IDMToolBarItem

  The IDMToolBarItem class represents tool-bar-specific items in a direct manipulation. Tool bars create objects of the IDMToolBarItem class when either of the following occurs:

  - A tool bar button item is dragged over a tool bar during a direct manipulation
  - A menu drag item is dragged over a tool bar during a direct manipulation

  This class provides virtual functions that implement direct manipulation support for tool bars. You can derive item classes to support the direct manipulation of tool bar items if the default Open Class Library support does not meet your requirements.
  Note: This class does not support tool bars as the source of a direct manipulation.

### IDMToolBarItem - Member Functions and Data by Group

### Constructors & Destructor

You can construct and destruct objects of this class.

~IDMToolBarItem

      public:
      virtual ~IDMToolBarItem()

Supported Platforms

  Windows | OS/2 | AIX
  Yes | Yes | Yes

IDMToolBarItem

      public:
      IDMToolBarItem(const IDMItem::Handle& dragItem)

  Constructs IDMToolBarItem objects for the target of a direct manipulation. It is called by the member function, IDMItemProviderFor::provideTargetItemFor, of the tool bar's item provider for the tool bar item class.

Supported Platforms

  Windows | OS/2 | AIX
  Yes | Yes | Yes

### Drop Processing

Use these members during the drop operation of a direct manipulation.

targetDrop

      public:
      virtual bool targetDrop(IDMTargetDropEvent& event)

  Implements tool-bar-item-specific rendering when the drag item that represents a tool bar button or a menu item object is dropped on a tool bar. This function processes the drop in one of the following ways:

  - If the drag was initiated from a drop down menu, a new tool bar button is created based upon the bitmap and text information in the drag object. The button is placed at the end of the tool bar.
  - If an existing tool bar button is dropped on a tool bar, it is treated as a move and is placed at the end of the tool bar.

  Derived classes should override this function if the default support does not meet your requirements.
  Note: Each tool bar button, within the context of a tool bar, must have a unique identifier (ID). The drop is rejected if a duplicate ID is detected within the same tool bar.

Supported Platforms

  Windows | OS/2 | AIX
  Yes | Yes | Yes
