Class CPrintSetup

class CPrintSetup : public CBase, private MFieldPageNumInfo;

Description

Print setup information.

This class stores the information needed to set up, start and stop a print job. This includes the target printer device, the page margins and the header and footer. The page specification, (page orientation and page dimensions) can be set via the printer device.

Print setup information is associated with a document and is stored as part of the persistent form of the document. Print parameters on the other hand, (class TPrintParameters) are associated with a particular print request, not with the document itself, so are not part of the print setup information.

Derivation

• MFieldPageNumInfo - Specifies the mixin protocol for evaluating a current page number field
• CBase - Base class for all classes to be instantiated on the heap

• CPrintSetup - Print setup information

static IMPORT_C CPrintSetup *NewL();

Description

Allocates and constructs an uninitialised CPrintSetup object.

After construction, the print settings, including the target printer device and the page specification must be set before printing can begin.

Return value

CPrintSetup * The print setup object

virtual IMPORT_C ~CPrintSetup();

Description

Destructor.

This frees all resources owned by the CPrintSetup object, prior to its destruction.

IMPORT_C void AddPrinterDriverDirL(const TDesC &aDriverDir);

Description

Adds a search path for printer drivers.

This function must be called before a model name list can be created. It can be called repeatedly to add a number of paths to the search list.

When a printer model name list is requested (using ModelNameListL()), the directories specified in each of the search paths are scanned on all non-remote drives for .pdr files, indicating the models supported. If any path contains a drive, that drive alone is searched.

Parameters

const TDesC &aDriverDir Path which specifies a directory in which to search for printer drivers. Any filename in the path is ignored. If the path is already in the list, it is not added again.

Leave codes

KErrNoMemory There is insufficient memory to perform the operation.

IMPORT_C CPrinterModelList *ModelNameListL(RFs &aFs);

Description

Gets the names of all printer models supported.

The function scans all directories in the search path list which were added using AddPrinterDriverDirL(). It returns a list of the printer models supported by the .pdr files found in those directories.

Parameters

RFs &aFs A connection to a file server session.

Return value

CPrinterModelList * The list of printer models supported.

Leave codes

KErrNoMemory There is insufficient memory to perform the operation.

IMPORT_C void FreeModelList();

Description

Deletes and sets the printer model list to NULL.

IMPORT_C void CreatePrinterDeviceL(TInt aModelIndex);

Description

Selects the target printer device by its index into the list of printer models.

Unlike the other overload of this function, a panic occurs if no printer model list has previously been created using ModelNameListL().

If a print process is taking place when this function is called, it is aborted.

The existing printer device's page specification is preserved.

Parameters

TInt aModelIndex Index of the printer device into the list of printer devices.

Leave codes

KErrNoMemory There is insufficient memory to perform the operation.

IMPORT_C void CreatePrinterDeviceL(TUid aModelUid, RFs &aFs);

Description

Selects the target printer device, from the list of printer models.

If no printer model name list has previously been created by a call to ModelNameListL(), this function will temporarily create one, freeing it before exiting.

If no printer model in the list has the UID specified, the first printer model in the list is selected by default. If the list contains no printer models at all, a leave occurs.

If a print process is taking place when this function is called, it is aborted.

The existing printer device's page specification is preserved.

Parameters

TUid aModelUid A UID which identifies a printer device. RFs &aFs A connection to a file server session.

Leave codes

KErrNoMemory There is insufficient memory to perform the operation. KErrNotFound The printer model list contains no printer devices.

IMPORT_C CPrinterDevice *PrinterDevice() const;

Description

Gets the selected printer device.

Return value

CPrinterDevice * The selected printer device.

Panic codes

PRINT 1 No printer device has been selected. Use CreatePrinterDevice() to select one.

IMPORT_C CPrinterDriverUI *CreatePrinterDriverUIL();

Description

Creates a user interface for the target printer device, if the current printer driver has a matching .udl file.

Returns a NULL pointer if no matching .udl file was found. The UI can provide such things as custom print setup dialogs.

Return value

CPrinterDriverUI * The UI for the selected printer device.

Panic codes

PRINT 1 No printer device has been selected. Use CreatePrinterDevice() to select one.

IMPORT_C void EndPrint();

Description

Aborts the print operation, if one is currently taking place.

If a print process observer exists, its NotifyPrintEnded() function is called with KErrCancel.

See also:

• MPrintProcessObserver

IMPORT_C TInt StartPrintL(const TPrintParameters &aPrintParams, MPageRegionPrinter &aBodyPrinter, CPrinterPort *aPort, MPrintProcessObserver *anObserver);

Description

If a print process observer is specified, this function calls its NotifyPrintStarted() function.

Parameters

const TPrintParameters &aPrintParams The parameters for the print job. MPageRegionPrinter &aBodyPrinter An object which implements the page region printer interface. CPrinterPort *aPort The printer port. Must be provided if the selected printer device requires one. MPrintProcessObserver *anObserver An optional object which implements the print process observer interface.

Return value

TInt KErrNone if the operation completed successfully, KErrAlreadyExists if a print process is already taking place, or another of the system-wide error codes.

Panic codes

PRINT 1 No printer device has been selected. Use CreatePrinterDevice() to select one.

IMPORT_C TInt StartPreviewPrintL(const TPrintParameters &aPrintParams, MPageRegionPrinter &aBodyPrinter, MPrintProcessObserver *anObserver, CGraphicsDevice &aPreviewDev, const TRect &aHeaderRectInPixels, const TRect &aFooterRectInPixels, TInt aNumBands);

Must be supplied if the header or footer contains pictures which should be restored.

IMPORT_C void ExternalizeL(RWriteStream &aStream) const;

Description

Externalises a CPrintSetup object to a write stream.

The presence of this function means that the standard templated operator<<() (defined in s32strm.h) is available to externalise objects of this class.

This function does not externalise the rich text components of the header and footer (e.g. fields, pictures and rich text-specific formatting), so it may need to be accompanied by a call to StoreComponentsL().

Parameters

RWriteStream &aStream Stream to which the object should be externalised.

Panic codes

PRINT 1 No printer device has been selected. Use CreatePrinterDevice() to select one.

IMPORT_C void InternalizeL(RReadStream &aStream);

Description

Internalises a CPrintSetup object from a read stream.

The presence of this function means that the standard templated operator>>() (defined in s32strm.h) is available to internalise objects of this class.

This function does not restore the rich text components of the header and footer, (e.g. fields, pictures and rich text-specific formatting), so it may need to be accompanied by a call to RestoreComponentsL().

Parameters

RReadStream &aStream Stream from which the object should be internalised.

private: virtual TInt UpdateFieldPageNum() const;

Description

Implementations of this function should return the current page number.

Return value

TInt The page number.
