<p> Draws the ComplexControl <em>control</em> using the painter <em>p</em> in the
area <em>r</em>. Colors are used from the color group <em>cg</em>. The <em>sub</em>
argument specifies which SubControls to draw. Multiple SubControls
can be OR'ed together. The <em>subActive</em> argument specifies which
SubControl is active.
<p> The rect <em>r</em> should be in logical coordinates. Reimplementations
of this function should use <a href="#visualRect">visualRect</a>() to change the logical
coordinates into screen coordinates when using <a href="#drawPrimitive">drawPrimitive</a>() and
<a href="#drawControl">drawControl</a>().
<p> The <em>how</em> argument is used to control how the ComplexControl is
drawn. Multiple flags can OR'ed together. See the table below for
an explanation of which flags are used with the various
ComplexControls.
<p> The <em>widget</em> argument is a pointer to a <a href="qwidget.html">QWidget</a> or one of its
subclasses. The widget can be cast to the appropriate type based
on the value of <em>control</em>. The <em>opt</em> argument can be used to
pass extra information required when drawing the ComplexControl.
Note that <em>opt</em> may be the default value even for ComplexControls
that can make use of the extra options. See the table below for
the appropriate <em>widget</em> and <em>opt</em> usage:
