Detailed Description

Windows-specific class to create a printer device context.

Library: winviews

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 herself.

An example showing how to implement it is located in the samples/foundation/printing directory.

◆ getFirstLastPages()

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

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

Parameters
firstPageSet on return to the number of the first page to be printed (starting at 1).
lastPageSet on return to the number of the last page to be printed (starting at 1).
Returns
Indicates, if IlTrue, that the values were updated in the dialog.

Implemented in IlvWindowsPrinterDCDialogFactory.

◆ getHDC()

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.

◆ getMinMaxPageRange()

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
minPageSet on return to the minimum value.
maxPageSet on return to the maximum value.
Returns
Indicates, when IlTrue, that the values are used by the dialog.

Implemented in IlvWindowsPrinterDCDialogFactory.

◆ getOrientation()

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.

◆ getPaperLength()

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.

◆ getPaperSize()

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.

◆ getPaperWidth()

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.

◆ hasPageSettingDialog()

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 otherwise.

Implemented in IlvWindowsPrinterDCDialogFactory.

◆ initializeSettings()

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.

◆ isInitialized()

IlBoolean IlvWindowsPrinterDCFactory::isInitialized ( ) const

Indicates whether the settings were initialized.

Returns
IlTrue if the DC was initialized, and IlFalse otherwise.

◆ isVisible()

virtual IlBoolean IlvWindowsPrinterDCFactory::isVisible ( ) const
pure virtual

Gets the visibility of the dialog, if any.

Returns
The visibility of the dialog, if any.

Implemented in IlvWindowsPrinterDCDialogFactory.

◆ resetSettings()

virtual void IlvWindowsPrinterDCFactory::resetSettings ( )
pure virtual

Resets the printer settings used to create the printer DC.

This pure virtual function must be overloaded in inherited classes.

Implemented in IlvWindowsPrinterDCDialogFactory.

◆ setFirstLastPages()

virtual void IlvWindowsPrinterDCFactory::setFirstLastPages ( IlUShort  firstPage,

)
pure virtual

Sets the value of the first and last pages to be printed.

Parameters
firstPageThe value (starting at 1) of the first page to be printed.
lastPageThe value (starting at 1) of the last page to be printed.

Implemented in IlvWindowsPrinterDCDialogFactory.

◆ setMinMaxPageRange()

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
minPageThe minimum value for the page range.
maxPageThe maximum value for the page range.

Implemented in IlvWindowsPrinterDCDialogFactory.

◆ setOrientation()
