Detailed Description

IMFExDropCandidate is the interface for a drop candidate. A drop candidate is the object that excapsulate that object that is drag and dropped.

To create your own drop candiate, you should derive your object from TBasicDropCandidate that provides a default implementation of IMFExDropCandidate. The family ID for a drop area is 'drpC'.

Member Function Documentation

virtual void MCCOMAPI IMFExDropCandidate::FinishedDrag (  boolean  inSuccessful  )  [pure virtual]

Called at the end of the drap. Parameters: inSuccessful  True ifthe drop was successful. Implemented in TBasicDropCandidate.

virtual MCCOMErr MCCOMAPI IMFExDropCandidate::GetData (  IDType  inFlavor, MFDragDropType  inMoveOrCopy, void **  outData )  [pure virtual]

Returns the data of the object in a given format. Parameters: inFlavor  The format of the data. inMoveOrCopy  Specifies whether the data should be copied or moved. outData  The data. Implemented in TBasicDropCandidate.

virtual void MCCOMAPI IMFExDropCandidate::GetOfferedFlavors (  TMFDragFlavors &  outFlavors  )  [pure virtual]

Returns the list of format in which the data can be converted. Parameters: outFlavors  The list of formats. Implemented in TBasicDropCandidate.

virtual void MCCOMAPI IMFExDropCandidate::GetOrigin (  void **  outOrigin  )  [pure virtual]

Returns the origin (for example the scene for an instance) of the drop candidate for use in determining whether to move or copy the item (clients should check for non-NULL). Parameters: outOrigin  A pointer to the origin. Implemented in TBasicDropCandidate.

virtual void MCCOMAPI IMFExDropCandidate::OnNoDrag (   )  [pure virtual]

Called when no drag occured. Implemented in TBasicDropCandidate.

virtual void MCCOMAPI IMFExDropCandidate::PrepareToDrag (   )  [pure virtual]

Called at the beginning of the drap Implemented in TBasicDropCandidate.
