/**

\class KDChartPainter KDChartPainter.h
|
|
|
|
\brief An abstract base class that defines an interface for classes
|
|
that implement chart drawing.
|
|
|
|
Applications don't use this class directly (except for
|
|
registering/unregistering, see below) new chart implementations,
|
|
but instead use the method KDChart::paint() which takes care of the
|
|
correct creation and deletion of the painter implementation
|
|
used. Or they use KDChartWidget which handles everything
|
|
automatically.
|
|
|
|
This class cannot be instantiated directly. Even the concrete
|
|
subclasses are not instantiated directly, but are instantiated via
|
|
KDChartPainter::create() which creates a subclass according to the
|
|
parameters passed.
|
|
|
|
Application developers can provide their own chart implementations
|
|
by subclassing from KDChartPainter, instantiating their subclass
|
|
and registering their implementation with
|
|
KDChartPainter::registerPainter(). These registrations can be
|
|
removed with KDChartPainter::unregisterPainter().
|
