Static Public Member Functions inherited from xiiDragDropHandler
static bool	IsHandlerActive ()
	Returns whether the last call to BeginDragDropOperation() was successful and a handler is now in effect.
static bool	BeginDragDropOperation (const xiiDragDropInfo *pInfo, xiiDragDropConfig *pConfigToFillOut=nullptr)
	Call this when a drag enter event occurs. Return value indicates whether a xiiDragDropHandler was found to handle the operation. If not, subsequent drag & drop updates are ignored.
static void	UpdateDragDropOperation (const xiiDragDropInfo *pInfo)
	Call this when a drag event occurs. Ignored if BeginDragDropOperation() was not successful.
static void	FinishDragDrop (const xiiDragDropInfo *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 xiiDragDropInfo *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 xiiDragDropInfo *pInfo)
	Executes a complete drop action on a target that does not support continuous dragging. See also CanDropOnly().

Member Function Documentation

CanHandle()

float xiiMaterialDragDropHandler::CanHandle ( const xiiDragDropInfo * 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 xiiDragDropHandler.

OnDragBegin()

void xiiMaterialDragDropHandler::OnDragBegin ( const xiiDragDropInfo * pInfo )

overrideprotectedvirtual

Called shortly after CanHandle returned true to begin handling a drag operation.

Implements xiiDragDropHandler.

OnDragCancel()

void xiiMaterialDragDropHandler::OnDragCancel ( )

overrideprotectedvirtual

Called when the drag operation leaves the designated area. The handler will be destroyed after this. It should clean up all temporary objects that it created before.

Implements xiiDragDropHandler.

OnDragUpdate()

void xiiMaterialDragDropHandler::OnDragUpdate ( const xiiDragDropInfo * pInfo )

overrideprotectedvirtual

Called to update the drag operation with the latest state.

Implements xiiDragDropHandler.

OnDrop()

void xiiMaterialDragDropHandler::OnDrop ( const xiiDragDropInfo * pInfo )

overrideprotectedvirtual

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

Implements xiiDragDropHandler.

RequestConfiguration()

void xiiMaterialDragDropHandler::RequestConfiguration ( xiiDragDropConfig * pConfigToFillOut )

overrideprotectedvirtual

Potentially called by the drag drop target to request information about how to determine the xiiDragDropInfo data.

Reimplemented from xiiDragDropHandler.
