Detailed Description

A Function encapsulates a mathematical function with rectangular domain. The user has to adapt the pure virtual operator() to get a working object. Also, the client code should call setDomain, setMesh and create for reasonable operating conditions.

Member Function Documentation

virtual double operator()	(	double	x,
		double	y
	)			[pure virtual]

Overwrite this.

void setMinZ

(

double

val

)

Sets minimal z value.

void setMaxZ

(

double

val

)

Sets maximal z value.

bool create

(

Qwt3D::SurfacePlot &

plotWidget

)

[virtual]

Assigns a new SurfacePlot and creates a data representation for it.

bool create

(

)

[virtual]

Creates data representation for the actual assigned SurfacePlot.

void assign

(

Qwt3D::SurfacePlot &

plotWidget

)

Assigns the object to another widget. To see the changes, you have to call this function before create().

void assign

(

Qwt3D::SurfacePlot *

plotWidget

)

Assigns the object to another widget. To see the changes, you have to call this function before create().
