void CQGLLayoutViewer::change_style	(	const CLRenderInformationBase *	pRenderInfo,
		bool	defaultStyle = `false`
	)

The default style indicates that the passed in render information is a default style. The renderer uses this information to determine whether roles for species reference glyphs need to be deduced.

double CQGLLayoutViewer::fitToScreen ( )

Calculates the ratio that is needed to fit the diagram on the current viewport and sets this as the zoom factor. The methods returns the new zoom factor.
