Basic Drop Candidate class. Derive from this for a default implementation of an IMFExDropCandidate.
TBasicDropCandidate::TBasicDropCandidate | ( | ) |
virtual uint32 MCCOMAPI TBasicDropCandidate::AddRef | ( | ) | [inline, virtual] |
Increments the reference count of the object
Reimplemented from TBasicPart.
virtual void MCCOMAPI TBasicDropCandidate::FinishedDrag | ( | boolean | inSuccessful | ) | [virtual] |
Called at the end of the drap.
inSuccessful | True ifthe drop was successful. |
Implements IMFExDropCandidate.
virtual MCCOMErr MCCOMAPI TBasicDropCandidate::GetData | ( | IDType | inFlavor, | |
MFDragDropType | inMoveOrCopy, | |||
void ** | outData | |||
) | [virtual] |
Returns the data of the object in a given format.
inFlavor | The format of the data. | |
inMoveOrCopy | Specifies whether the data should be copied or moved. | |
outData | The data. |
Implements IMFExDropCandidate.
virtual void MCCOMAPI TBasicDropCandidate::GetOfferedFlavors | ( | TMFDragFlavors & | outFlavors | ) | [virtual] |
Returns the list of format in which the data can be converted.
outFlavors | The list of formats. |
Implements IMFExDropCandidate.
virtual void MCCOMAPI TBasicDropCandidate::GetOrigin | ( | void ** | outOrigin | ) | [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).
outOrigin | A pointer to the origin. |
Implements IMFExDropCandidate.
virtual boolean MCCOMAPI TBasicDropCandidate::NeedToBeDropedOnTree | ( | IDType | inFlavor, | |
MFDragDropType | inMoveOrCopy | |||
) | [inline, virtual] |
Implements IMFExDropCandidate.
virtual void MCCOMAPI TBasicDropCandidate::OnNoDrag | ( | ) | [virtual] |
Called when no drag occured.
Implements IMFExDropCandidate.
virtual void MCCOMAPI TBasicDropCandidate::PrepareToDrag | ( | ) | [virtual] |
Called at the beginning of the drap
Implements IMFExDropCandidate.
virtual MCCOMErr MCCOMAPI TBasicDropCandidate::QueryInterface | ( | const MCIID & | riid, | |
void ** | ppvObj | |||
) | [virtual] |
Check if the object supports a given interface and returns a pointer to that interface if it does. Note that QueryInterface will increment the reference count of the object by one if the interface is found.
riid | GUID of the interface | |
ppvObj | A pointer to the pointer being returned. |
Reimplemented from TBasicPart.
