Functions

The API includes four function calls, which are declared in the header file Dnd.h and outlined in the following paragraphs. These functions are described in greater detail in later sections.

• DtDndDragStart() starts a drag in response to a user action.

• DtDndCreateSourceIcon() creates a source icon to use with DtDndDragStart().

• DtDndDropRegister() registers a widget as a drop zone. Drop zone registration usually occurs immediately after the widget is created, but may be performed at any time.

• DtDndDropUnregister() unregisters a previously registered widget. A drop zone is usually unregistered immediately before being destroyed, but may be unregistered any time after being registered.
