Detailed Description

The abstract base class for a factory that creates objects closely related to the graphics subsystem in use.

The factory objects create objects of concrete classes derived from ViewBase and FontBase. Known examples of concrete view factorys are JavaViewFactory, OpenGLViewFactory and QtViewFactory.

Constructor & Destructor Documentation

ViewFactory::ViewFactory (   )  [protected]

The default constructor is disallowed. Definition at line 16 of file ViewFactory.cxx. References m_instance.

ViewFactory::ViewFactory (  const ViewFactory &   )  [private]

The disallowed copy constructor.

virtual ViewFactory::~ViewFactory (   )  [inline, virtual]

The virtual destructor. The virtual destrcutor which is only needed to keep warning messages from some compilers such as Gcc 4.0.0. Definition at line 55 of file ViewFactory.h.

Member Function Documentation

virtual FontBase* ViewFactory::createFont (   )  const [pure virtual]

Creates a default FontBase object. Implemented in QtViewFactory.

virtual ViewBase* ViewFactory::createView (  PlotterBase *  plotter  )  const [pure virtual]

Creates a view for the plotter. Implemented in QtViewFactory. Referenced by CanvasView::addPlotDisplay(), DisplayController::createTextView(), and XmlController::createView().

Member Data Documentation

ViewFactory * ViewFactory::m_instance = 0 [static, protected]

An instance of the default view factory. It should be created at the application initialization time for the default concrete view factory. Definition at line 14 of file ViewFactory.cxx. Referenced by instance(), QtViewFactory::instance(), and ViewFactory().
