		const IPMUnknown *	hitObj
	)

pure virtual

Description: Can start text drag based on current selection?

Parameters

view	pointer to the control view under the mouse
mousePt	location of current mouse position
hitObj	an IPMUnknown pointer from a frame from hittesting at the mousePt. May be nil.

virtual ErrorCode IDragDropTextSuite::PrepareDragDataSource	(	IDataExchangeHandler *	handler,
		IDragDropSource *	source
	)

pure virtual

Description: Prepare text data source for drag and drop operation

Parameters

handler pointer to IDataExchangeHandler

Returns: ErrorCode the result of adding source data to the exchange handler. An alert will be displayed if kSuccess is not returned.

virtual bool16 IDragDropTextSuite::TextRangeOverlapsSelection	(	UIDRef &	sourceStoryUIDRef,
		UIDRef &	destStoryUIDRef,
		RangeData &	destRange,
		DragDrop::eCommandType	type
	)

pure virtual

Description: Does the indicated text range overlap the text selection (in the destination)?

Parameters

sourceStoryUIDRef	Reference to the source story (may be kInvalidUIDRef)
destStoryUIDRef	Reference to the story to drop into
destRange	text range at hit location (length of 1)
type	an enum of type DragDrop::eCommandType. kDragMove for moving text, otherwise use kDrop to copy.
