<h2>Detailed Description</h2>
<p>The QStylePainter class is a convenience class for drawing <a href="qstyle.html">QStyle</a> elements inside a widget.</p>
<p>QStylePainter extends <a href="qpainter.html">QPainter</a> with a set of high-level <tt>draw...()</tt> functions implemented on top of <a href="qstyle.html">QStyle</a>'s API. The advantage of using QStylePainter is that the parameter lists get considerably shorter. Whereas a <a href="qstyle.html">QStyle</a> object must be able to draw on any widget using any painter (because the application normally has one <a href="qstyle.html">QStyle</a> object shared by all widget), a QStylePainter is initialized with a widget, eliminating the need to specify the <a href="qwidget.html">QWidget</a>, the <a href="qpainter.html">QPainter</a>, and the <a href="qstyle.html">QStyle</a> for every function call.</p>
<p>Example using <a href="qstyle.html">QStyle</a> directly:</p>
<pre> void MyWidget::paintEvent(QPaintEvent * <span class="comment">/* event */</span>)
{
QPainter painter(this);
QStyleOptionFocusRect option;
option.initFrom(this);
option.backgroundColor = palette().color(QPalette::Background);
style()->drawPrimitive(QStyle::PE_FrameFocusRect, &option, &painter, this);
}</pre>
<p>Example using QStylePainter:</p>
<pre> void MyWidget::paintEvent(QPaintEvent * <span class="comment">/* event */</span>)
{
QStylePainter painter(this);
QStyleOptionFocusRect option;
option.initFrom(this);
option.backgroundColor = palette().color(QPalette::Background);
painter.drawPrimitive(QStyle::PE_FrameFocusRect, option);
}</pre>
