For this it saves all 44 normal drawing operations for each printed page to a metafile, then spooling 45 the metafiles timer based to a normal printer. The application can act in the meantime 46 including changing the original document without influencing the print job. 47 48 On some systems (currently Mac/Aqua Cocoa) ImplQPrinter has the additional 49 purpose of adapting to the print system: here theprint systems starts a 50 job and will not return from that function until it has ended; to do so 51 it queries for each consecutive page to be printed. Also the Cocoa print system 52 needs to know the number of pages BEFORE starting a print job. Since our Printer 53 does not know that, we need to do the completing spooling to ImplQPrinter before 54 we can actually print to the real print system. Let's call this the pull model 55 instead of the push model (because the systems pulls the pages). 56 */ 57 58 class ImplQPrinter : public Printer, public vcl::DeletionNotifier 59 { 60 private: 61 Printer* mpParent; 62 std::vector< QueuePage* > maQueue; 63 AutoTimer maTimer; 64 bool mbAborted; 65 bool mbUserCopy; 66 bool mbDestroyAllowed; 67 bool mbDestroyed; 68 69 GDIMetaFile maCurPageMetaFile; 70 long mnMaxBmpDPIX; 71 long mnMaxBmpDPIY; 72 sal_uLong mnRestoreDrawMode; 73 int mnCurCopyCount; 74 75 DECL_LINK( ImplPrintHdl, Timer* ); 76 77 ~ImplQPrinter(); 78 79 void ImplPrintMtf( GDIMetaFile& rMtf, long nMaxBmpDPIX, long nMaxBmpDPIY ); 80 81 ImplQPrinter( const ImplQPrinter& rPrinter ); 82 Printer& operator =( const ImplQPrinter& rPrinter ); 83 84 void PrePrintPage( QueuePage* ); 85 void PostPrintPage(); 86 87 public: 88 89 ImplQPrinter( Printer* pParent ); 90 void Destroy(); 91 92 void StartQueuePrint(); 93 void EndQueuePrint(); 94 void AbortQueuePrint(); 95 void AddQueuePage( GDIMetaFile* pPage, sal_uInt16 nPage, sal_Bool bNewJobSetup ); 96 97 bool IsUserCopy() const { return mbUserCopy; } 98 void SetUserCopy( bool bSet ) { mbUserCopy = bSet; } 99 100 /** 101 used by pull implementation to emit the next page 102 */ 103 void PrintPage( unsigned int nPage ); 104 /** 105 used by pull implementation to get the number of physical pages 106 (that is how often PrintNextPage should be called) 107 */ 108 sal_uLong GetPrintPageCount() const; 109 110 /** 111 used by pull implementation to get ranges of physical pages that 112 are to be printed on the same paper.
