/*!
Renders the delegate using the given \a painter and style \a option for
the item specified by \a index.
When reimplementing this function in a subclass, you should update the area
held by the option's \l{QStyleOption::rect}{rect} variable, using the
option's \l{QStyleOption::state}{state} variable to determine the state of
the item to be displayed, and adjust the way it is painted accordingly.
For example, a selected item may need to be displayed differently to
unselected items, as shown in the following code:
\snippet examples/itemviews/pixelator/pixeldelegate.cpp 2
\dots
After painting, you should ensure that the painter is returned to its
the state it was supplied in when this function was called. For example,
it may be useful to call QPainter::save() before painting and
QPainter::restore() afterwards.
