Detailed Description

Plot3D handles all the common features for plotting widgets beyond the low-level extensions of ExtGLWidget - coordinate system, labeling and more. It contains some pure virtual functions and is - in this respect - an abstract base class. It's nevertheless no pure interface. The class provides interfaces for basic data controlled color allocation.

Constructor & Destructor Documentation

Plot3D ( QWidget *  parent = 0,
const QGLWidget *  shareWidget = 0 

This should be the first call in your derived classes constructors.

~Plot3D (  )  [virtual]

Release allocated resources

Member Function Documentation

QPixmap renderPixmap ( int  w = 0,
int  h = 0,
bool  useContext = false

void setPlotStyle ( Qwt3D::PLOTSTYLE  val  ) 

Set plotting style.

Set plotstyle for the standard plotting types. An argument of value Qwt3D::USER is ignored.

Qwt3D::Enrichment * setPlotStyle ( Qwt3D::Enrichment const &  obj  ) 

Set plotstyle to Qwt3D::USER and an associated enrichment object.

Qwt3D::PLOTSTYLE plotStyle (  )  const [inline]

Set user-defined isoline vector;.

unsigned isolines (  )  const [inline]

Returns number of isolines.

void setSmoothMesh ( bool  val  )  [inline]

Enables/disables smooth data mesh lines. Default is false.

bool smoothDataMesh (  )  const [inline]

True if mesh antialiasing is on.

void setBackgroundColor ( Qwt3D::RGBA  rgba  ) 

Sets widgets background color.

Qwt3D::RGBA backgroundRGBAColor (  )  const [inline]

Returns the widgets background color.

void setMeshColor ( Qwt3D::RGBA  rgba  ) 

Sets color for data mesh.

Qwt3D::RGBA meshColor (  )  const [inline]

Returns color for data mesh.

void setMeshLineWidth ( double  lw  )

void setCoordinateStyle ( Qwt3D::COORDSTYLE  st  ) 

Sets style of coordinate system.

Set style of coordinate system

void setPolygonOffset ( double  val  ) 

Set Polygon offset. The function affects the OpenGL rendering process. Try different values for surfaces with polygons only and with mesh and polygons

double polygonOffset (  )  const [inline]

Returns relative value for polygon offset [0..1].

void setTitlePosition ( double  rely,

Returns true if valid data available, false else.

bool save ( QString const &  fileName,
QString const &  format 
) [virtual, slot]

Saves content.

Saves content in one of the registered output formats. To modify the behaviour for more complex output handling use IO::outputHandler.

void paintGL (  )  [protected]

void resizeGL ( int  w,
int  h 
) [protected]
