Detailed Description

An engine painting data on pages using TQPainter. The engine allows for random access to any page.

Member Function Documentation

◆ calculatePagesCount()

void KexiSimplePrintingEngine::calculatePagesCount ( TQPainter & painter )

Calculates pafe count that can be later obtained using pagesCount(). Page count can depend on painter (printer/screen) and on printing settings.

Definition at line 539 of file kexisimpleprintingengine.cpp.

◆ clear()

void KexiSimplePrintingEngine::clear ( )

Definition at line 193 of file kexisimpleprintingengine.cpp.

◆ done()

bool KexiSimplePrintingEngine::done ( )

Definition at line 176 of file kexisimpleprintingengine.cpp.

◆ eof()

bool KexiSimplePrintingEngine::eof ( ) const

inline

Returns: true when all records has been painted

Definition at line 80 of file kexisimpleprintingengine.h.

◆ init()

bool KexiSimplePrintingEngine::init	(	KexiDB::Connection &	conn,
		KexiDB::TableOrQuerySchema &	tableOrQuery,
		const TQString &	titleText,
		TQString &	errorMessage )

Todo: primitive: data should be loaded on demand

Definition at line 136 of file kexisimpleprintingengine.cpp.

◆ pagesCount()

uint KexiSimplePrintingEngine::pagesCount ( ) const

inline

Returns: number of pages. Can be used after calculatePagesCount().

Definition at line 83 of file kexisimpleprintingengine.h.

◆ paintedPages()

uint KexiSimplePrintingEngine::paintedPages ( ) const

inline

Returns: number of painted pages so far. If eof() is true, this number is equal to total page count.

Definition at line 87 of file kexisimpleprintingengine.h.

◆ paintPage

void KexiSimplePrintingEngine::paintPage	(	int	pageNumber,
		TQPainter &	painter,
		bool	paint = true )

slot

Paints a page number pageNumber (counted from 0) on painter. If paint is false, drawings are only computed but not painted, so this can be used for calculating page number before printing or previewing.

Todo: add setting

Todo: break large records anyway...

Definition at line 202 of file kexisimpleprintingengine.cpp.

◆ paintRecord()

void KexiSimplePrintingEngine::paintRecord	(	TQPainter &	painter,
		KexiTableItem *	item,
		int	cellMargin,
		double &	y,
		uint	paintedRows,
		bool	paint,
		bool	printing )
