Member Function Documentation

virtual void ViewBase::drawMag (  float  , float  , int  , float  )  [pure virtual]

Draws the exponent on the axis label. The arguments stand for the starting position of the writing ( x, y ), for the value of the magnitude ( mag ), and for the font ( fontsize ). Bug: @@ This method should not exist. The x, y coordinates of the position of the magnitude should be calculated in the AxisRepBase class and that class should use drawText. Implemented in QtViewImp.

virtual void ViewBase::drawSelf (   )  [virtual]

Draws itself.

virtual void ViewBase::drawSquare (  double  , double  , double  , double  , int  , int  , int  )  [pure virtual]

Draws a colored square. Used for shading on the cuts and the gray plot. Implemented in QtViewImp.

virtual void ViewBase::drawUserText (  const std::string &  , float  , float  , float  , float  , char  , char  )  [pure virtual]

Draws a text string at a point in the data coordinate system. Bug: Is this function used somewhere? Implemented in QtViewImp.

virtual void ViewBase::drawViewSquare (  float  , float  , float  , float  , int  , int  , int  )  [pure virtual]

Draws a colored square in view space. Used for shading on the cuts and the gray plot. Implemented in QtViewImp.

virtual void ViewBase::endPlot (   )  [pure virtual]

Finalizes a view when all drawing has been done. Implemented in QtView, and QtViewImp.

virtual double ViewBase::getAspectRatio (   )  const [virtual]

Get the aspect ratio.

PlotterBase* ViewBase::getPlotter (   )

Returns the plotter used by this view.

PlotterBase* ViewBase::getPlotter (   )  const

Returns the plotter used by this view.

virtual void ViewBase::initPlot (  double   )  [pure virtual]

Initializes a view before drawing. The view should check it size. The parameter aspect, if greater than 0.0, sets the aspect ratio of the view, i.e. the ratio of the width to the height. Implemented in QtView.

virtual void ViewBase::setDrawRect (  float  , float  , float  , float  )  [pure virtual]

Sets the drawing Rectangle in the devices coordinate system. Implemented in QtView.

virtual void ViewBase::setPlotter (  PlotterBase *   )  [virtual]

Sets the PlotterBase object to plotter. The ViewBase object does not own the plotter. If the plotter is being changed, it is up to client code to decide to destroy the previous plotter or not.

virtual void ViewBase::update (  const Observable *   )  [pure virtual]

Implements the update method of the Observer pattern. Derived classes should send a message to what ever object is the parent of this ViewBase object. Implements Observer. Implemented in QtView.

virtual float ViewBase::userToDrawColor (  double   )  const [pure virtual]

Converts a coordinate in user space to drawing space along the color (X) axis. Implemented in QtViewImp.

virtual float ViewBase::userToDrawX (  double   )  const [pure virtual]

Converts a coordinate in user space to drawing space along the X axis. Implemented in QtViewImp.

virtual float ViewBase::userToDrawY (  double   )  const [pure virtual]

Converts a coordinate in user space to drawing space along the Y axis. Implemented in QtViewImp.
