Detailed Description

Windows-specific class to create a printer device context.

Library: display

This class lets the user specify how to create the printer device context.

This class is abstract. The user can either use the provided implementation (IlvWindowsPrinterDCDialogFactory) or implement it himself. An example showing how to implement it is located in the samples/foundation/printing directory.

Constructor & Destructor Documentation

virtual IlvWindowsPrinterDCFactory::~IlvWindowsPrinterDCFactory ( )

virtual

The destructor.

The destructor is virtual and likely to be overloaded in inherited classes.

Member Function Documentation

virtual IlBoolean IlvWindowsPrinterDCFactory::getFirstLastPages ( IlUShort &  firstPage, IlUShort &  lastPage  ) const

pure virtual

Gets the first and last number of the pages to be printed.

This function stores the values (counted from 1) in its parameters. It returns a Boolean that indicates whether the values were filled in the dialog.

Parameters

firstPage	A reference to an IlUShort where the number of the first page to be printed (counted from 1) is stored.
lastPage	A reference to an IlUShort where the number of the last page to be printed (counted from 1) is stored.

Returns

A Boolean that indicates whether the values were filled in the dialog.

Implemented in IlvWindowsPrinterDCDialogFactory.

virtual HDC IlvWindowsPrinterDCFactory::getHDC ( ) const

pure virtual

Gets the printer HDC.

This pure virtual function must be overloaded in inherited classes.

The caller must delete the returned HDC when it is no longer needed.

Returns

0 when an error occurred, or a valid HDC otherwise.

Implemented in IlvWindowsPrinterDCDialogFactory.

virtual IlBoolean IlvWindowsPrinterDCFactory::getMinMaxPageRange ( IlUShort &  minPage, IlUShort &  maxPage  ) const

pure virtual

Gets the extremum values for the page range.

This function stores the values in its parameters. It returns a Boolean that indicates whether the values are used by the dialog.

Parameters

minPage	A reference to an IlUShort where the minimum value is stored.
maxPage	A reference to an IlUShort where the maximum value is stored.

Returns

A Boolean that indicates whether the values are used by the dialog.

Implemented in IlvWindowsPrinterDCDialogFactory.

virtual short IlvWindowsPrinterDCFactory::getOrientation ( ) const

pure virtual

Gets the orientation of the paper for the current settings of the printer.

This pure virtual function must be overloaded in inherited classes.

The values are the same as the ones specified in the member dmOrientation of the Windows structure DEVMODE.

Returns

The orientation of the paper.

Implemented in IlvWindowsPrinterDCDialogFactory.

virtual short IlvWindowsPrinterDCFactory::getPaperLength ( ) const

pure virtual

Gets the overridden length of the paper.

The value is specified in tenths of a millimeter.

Returns

The overridden length of the paper.

Implemented in IlvWindowsPrinterDCDialogFactory.

virtual short IlvWindowsPrinterDCFactory::getPaperSize ( ) const

pure virtual

Gets the size of the paper.

The values are the same as the ones specified in the member dmPaperSize of the Windows structure DEVMODE.

Returns

The size of the paper.

Implemented in IlvWindowsPrinterDCDialogFactory.

virtual short IlvWindowsPrinterDCFactory::getPaperWidth ( ) const

pure virtual

Gets the overridden width of the paper.

The value is specified in tenths of a millimeter.

Returns

The overridden width of the paper.

Implemented in IlvWindowsPrinterDCDialogFactory.

virtual IlBoolean IlvWindowsPrinterDCFactory::hasPageSettingDialog ( ) const

pure virtual

Returns an indication of whether a dialog that manages page numbers is used.

Returns

Returns IlTrue when a dialog that manages page numbers is used, IlFalse else.

Implemented in IlvWindowsPrinterDCDialogFactory.

virtual IlBoolean IlvWindowsPrinterDCFactory::initializeSettings ( )

pure virtual

Initializes the printer settings used to create the DC.

This pure virtual function must be overloaded in inherited classes.

Returns

IlFalse when canceled, otherwise IlTrue.

Implemented in IlvWindowsPrinterDCDialogFactory.

IlBoolean IlvWindowsPrinterDCFactory::isInitialized

(

)

const

Returns an indication of whether the settings were initialized.

Returns

The status of the DC.

virtual IlBoolean IlvWindowsPrinterDCFactory::isVisible ( ) const

pure virtual

Gets the visibility of the dialog if any.

This pure virtual function must be overloaded in inherited classes.

Returns

The visibility of the dialog if any.

Implemented in IlvWindowsPrinterDCDialogFactory.

virtual void IlvWindowsPrinterDCFactory::resetSettings ( )

pure virtual

Resets the printer settings used to create the printer DC.

Implemented in IlvWindowsPrinterDCDialogFactory.

virtual void IlvWindowsPrinterDCFactory::setMinMaxPageRange ( IlUShort  minPage, IlUShort  maxPage  )

pure virtual

Sets the extremum values for the page range.

If the values are equal, then the page range is not used by the dialog.

Parameters

minPage	The minimum value for the page range.
maxPage	The maximum value for the page range.

Implemented in IlvWindowsPrinterDCDialogFactory.

virtual void IlvWindowsPrinterDCFactory::setOrientation ( short  newOrientation, IlvDisplay &  display  )
