Constructor & Destructor Documentation

 

QwtCPointerData::QwtCPointerData (const double * x, const double * y, size_t size)

Constructor

Warning:

The programmer must assure that the memory blocks referenced by the pointers remain valid during the lifetime of the QwtPlotCPointer object.

Member Function Documentation

 

QwtDoubleRect QwtCPointerData::boundingRect () const [virtual]

Returns the bounding rectangle of the data. If there is no bounding rect, like for empty data the rectangle is invalid: QwtDoubleRect::isValid() == FALSE

Reimplemented from QwtData.

Definition at line 230 of file qwt_data.cpp.

References size().  

QwtData * QwtCPointerData::copy () const [virtual]

Return a pointer to a copy (virtual copy constructor)

Implements QwtData.

Definition at line 220 of file qwt_data.cpp.

References QwtCPointerData().  

QwtCPointerData & QwtCPointerData::operator= (const QwtCPointerData &)

Assignment.

Definition at line 194 of file qwt_data.cpp.

References d_size, d_x, and d_y.  

size_t QwtCPointerData::size () const [virtual]

Return the size of the data set

Implements QwtData.

Definition at line 205 of file qwt_data.cpp.

Referenced by boundingRect().  

double QwtCPointerData::x (size_t i) const [virtual]

Return the x value of data point i

Parameters:

i Index

Returns:

x X value of data point i

Implements QwtData.

Definition at line 210 of file qwt_data.cpp.  

double QwtCPointerData::y (size_t i) const [virtual]

Return the y value of data point i

Parameters:

i Index

Returns:

y Y value of data point i

Implements QwtData.
