Public Methods

 MathFunctionImplementor ()
virtual ~MathFunctionImplementor ()
virtual void installMathFunctions ()
 Implement this function to install any MathFunction's to a specific class.


Protected Methods

virtual void drawMathFunctions (QPainter *)
 Call this function when drawing the widget to get the visual for the installed math functionss.

virtual void cancelMathFunctions ()
 If a math function has been exec()'ed and is awaiting points to be selected, this will cancel it and return the widget to how it was.

void addMathFunction (MathFunction *, const char *id)
 Subclasses give a pointer to the MathFunction to add/install.

MathFunction * getMathFunction (const char *id)
 Returns the installed MathFunction with the given id.

virtual void sendCustomClick (QMouseEvent *, MathFunction *, double x, double y)
 Implement this if a certain math function needs more arguments other than mouse coodinates.

virtual int mathFunctionCount ()
void mathFunctionClick (QMouseEvent *e, double x, double y)
 Call this function when the mouse is clicked and pass it the generated QMouseEvent pointer and the actual x and y coordinates of where the mouse is.

Detailed Description

This class should be subclassed to allow a class to easily use MathFunction classes.

The subclass must implement installMathFunctions() and add any MathFunction's to the math_functions vector. Also, call drawMathFunctions(QPainter*) when painting the widget to get the visual for the installed math functions.

Member Function Documentation

void MathFunctionImplementor::addMathFunction (  MathFunction *   ,
const char *    id
)  [protected]
 

Subclasses give a pointer to the MathFunction to add/install.

This class will delete it

Definition at line 33 of file mathfunctionimplementor.cpp.

Referenced by ParametricGraph::installMathFunctions(), FunctionGraph::installMathFunctions(), and BasicGraph::installMathFunctions().

virtual void MathFunctionImplementor::installMathFunctions (    )  [inline, virtual]
 

Implement this function to install any MathFunction's to a specific class.

A math function should be added by calling addMathFunction( MathFunction*, const char * id ) Example: addMathFunction(new DistanceMathFunction(this), "Distance");

Reimplemented in BasicGraph, FunctionGraph, and ParametricGraph.
