Detailed Description

Abstract base class for mathematical functions.

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.

Constructor & Destructor Documentation

Function() [1/2]

Function::Function ( Qwt3D::SurfacePlot &  plotWidget )

explicit

Constructs a Function object and assigns a SurfacePlot.

Parameters

pw	Reference to a SurfacePlot widget

Function() [2/2]

Function::Function ( Qwt3D::SurfacePlot *  plotWidget )

explicit

Constructs a Function object and assigns a SurfacePlot.

Parameters

pw	Pointer to a SurfacePlot widget

Member Function Documentation

assign() [1/2]

void Function::assign

(

Qwt3D::SurfacePlot &

plotWidget

)

Assigns the object to another widget - call before create()

Parameters

plotWidget

Reference to a SurfacePlot widget

assign() [2/2]

void Function::assign

(

Qwt3D::SurfacePlot *

plotWidget

)

Assigns the object to another widget - call before create()

Parameters

plotWidget

Pointer to a SurfacePlot widget

create() [1/2]

bool Function::create ( )

virtual

Creates data representation for the actual assigned SurfacePlot.

Returns

True on success, false if mesh is too small or no widget assigned

Allocates data arrays, evaluates the function operator() over the mesh grid, clips values to the min/max z range, and loads data into the assigned SurfacePlot.

create() [2/2]

bool Function::create ( Qwt3D::SurfacePlot &  plotWidget )

virtual

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

Parameters

pl	Reference to a SurfacePlot widget

Returns

True on success

setMaxZ()

void Function::setMaxZ

(

double

val

)

Sets maximum z value for the function.

Parameters

val	Maximum z value

setMinZ()

void Function::setMinZ

(

double

val

)

Sets minimum z value for the function.

Parameters

val	Minimum z value
