Detailed Description

The class implements window with spectrum drawing. Natural group can be passed to control range of visualized spectrum.

Constructor & Destructor Documentation

ZqDlgSpectrum::ZqDlgSpectrum	(	QWidget *	parent,
		ZqbNatGroup &	NatF,
		int	n,
		float	dt,
		const float	vt[]
	)

Create dialog window to display the spectrum of given vector. Given natural group is used for frequency.

ZqDlgSpectrum::ZqDlgSpectrum	(	QWidget *	parent,
		ZqbNatGroup &	NatF,
		const ZqbRealTrace &	rtr
	)

Create dialog window to display the spectrum of given trace. Given natural group is used for frequency.

virtual ZqDlgSpectrum::~ZqDlgSpectrum ( )

virtual

Destroy the object.
