| TBool | BufferComplete(TUid, TRect &, TRect &) |

| Public Member Enumerations | |
|---|---|
| enum | TAlfScreenBufferEvent { ENone, ECreated, EDeleted, ERestored, EReleased, EBufferDrawComplete } |
| TBool | BufferComplete | ( | TUid | aBufferUid, |
| TRect & | aDisplayRect, | |||
| TRect & | aDirtyRect | |||
| ) | [pure virtual] | |||
Alf calls this when all the content have been draw to the back buffer. If EFalse is returned, the buffer is locked until the observer calls RequestNextBuffer(). If ETrue is returned, the RequestNextBuffer() is called automatically, immediately after this method returns.
