	Final call to finish the drag & drop operation. Handler is destroyed after this.

	Returns whether the last call to BeginDragDropOperation() was successful and a handler is now in effect.

static bool	BeginDragDropOperation (const ezDragDropInfo pInfo, ezDragDropConfig pConfigToFillOut=nullptr)
	Call this when a drag enter event occurs. Return value indicates whether a ezDragDropHandler was found to handle the operation. If not, subsequent drag & drop updates are ignored.

static void	UpdateDragDropOperation (const ezDragDropInfo *pInfo)
	Call this when a drag event occurs. Ignored if BeginDragDropOperation() was not successful.

static void	FinishDragDrop (const ezDragDropInfo *pInfo)
	Call this when a drop event occurs. Ignored if BeginDragDropOperation() was not successful.

static void	CancelDragDrop ()
	Call this when a drag leave event occurs. Ignored if BeginDragDropOperation() was not successful.

static bool	CanDropOnly (const ezDragDropInfo *pInfo)
	For targets that do not support full dragging, but only dropping on a single target, this allows to query whether there is a handler for the given target. See also DropOnly().

static bool	DropOnly (const ezDragDropInfo *pInfo)
	Executes a complete drop action on a target that does not support continuous dragging. See also CanDropOnly().

◆ CanHandle()

float ezComponentDragDropHandler::CanHandle ( const ezDragDropInfo * pInfo ) const

overrideprotectedvirtual

Used to ask a handler whether it knows how to handle a certain drag & drop situation.

The return value is a priority. By default CanHandle should return 0 or 1. To override an existing handler, values larger than 1 may be returned to take precedence.

Implements ezDragDropHandler.
