    \class HbStyle

    \brief HbStyle is the style management class for widgets

    HbStyle is used for the style management of widgets.

    It offers methods to create and update styled primitives. Briefly, styled primitives

    are HbWidgetBase-derived (which is a QGraphicsWidget) classes which draw a certain part of the user interface (for example

    the button background, or the slider thumb).

    A widget that chooses to be styled needs to create its primitives

    by using the createPrimitive method.

    Whenever the widget's state changes in a way that needs changes in drawing the primitive

    (such as button pressed down -> change the button background image) then the widget needs to

    call the updatePrimitive method.

    Generally primitives should be updated only when a state change occurs. When a widget uses primitives to construct

    itself it does not need a paint() method at all since primitives (widget's children) are doing the drawing.

    Painting for the primitives occurs from the graphics scene.

    HbStyle has some caching functionality and thus it should not be instantiated explicitly, but

    accessed only through HbWidget::style() or HbInstance::style() APIs.
