Detailed Description

KigPainter is an extended QPainter.

Currently the only difference is that it translates coordinates from and to the internal coordinates/ the widget coordinates...

It calls KigWidget::appendOverlay() for all of the places it draws in...

Definition at line 51 of file kigpainter.h.

Constructor & Destructor Documentation

KigPainter::KigPainter	(	const ScreenInfo &	r,
		QPaintDevice *	device,
		const KigDocument &	doc,
		bool	needOverlay = `true`
	)

construct a new KigPainter: the ScreenInfo is used to map the document coordinates to the widget coordinates.

This is done transparently to the objects. needOverlay sets whether we try to remember the places we're drawing on using the various overlay methods.

this is called by some drawing functions that modify the 'entire' screen, i.e.
