Detailed Description

This class encapsulates the object to be printed.

Library: ilvprint

This is an abstract class that is intended to be inherited to encapsulate any object(s) that can be drawn on an IlvPort so that they may be printed.

Instances of this class should be contained in an IlvPrintableDocument object.

Member Function Documentation

virtual IlvRect IlvPrintable::getBBox ( IlvPrintableJob const &  job ) const

pure virtual

Gets the bounding box of the area to print.

This pure virtual member function must be overloaded in inherited classes.

Parameters

job	The settings of the current print job.

Returns

The bounding box.

Implemented in IlvPrintableComposite, IlvPrintableFrame, IlvPrintableFormattedText, IlvPrintableScalable, and IlvPrintableText.

virtual IlBoolean IlvPrintable::internalPrint ( IlvPrintableJob const &  job ) const

protectedpure virtual

This function actually prints the document.

This pure virtual member function must be overloaded in inherited classes. It actually does the printing.

Parameters

job	The settings of the current print job.

Returns

IlFalse if an error occurred during the printing, or IlTrue otherwise.

Implemented in IlvPrintableComposite, IlvPrintableFrame, IlvPrintableGraphic, IlvPrintableFormattedText, IlvPrintableText, and IlvPrintableContainer.

void IlvPrintable::lock

(

)

Locks the current instance.

A reference counter is incremented internally.

IlvPrintable& IlvPrintable::operator=

(

IlvPrintable const &

other

)

The assignment operator.

Parameters

other

Another instance of this class.

Returns

A reference to the current object.

IlBoolean IlvPrintable::print

(

IlvPrintableJob const &

job

)

const

Prints the contents of the object.

This function uses the job given as the parameter to get the settings of the current print job.

It actually sets the clipping area and calls the virtual function internalPrint.

Parameters

job	The settings of the current print job.

Returns

IlFalse if an error occurred during the printing, or IlTrue otherwise.

void IlvPrintable::unlock

(

)

Unlocks the current instance.

A reference counter is decremented internally; when the reference counter reaches 0, the instance is deleted.
