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 class="cpp"> <span class="type">void</span> MyWidget<span class="operator">::</span>paintEvent(<span class="type"><a href="qpaintevent.html">QPaintEvent</a></span> <span class="operator">*</span> <span class="comment">/* event */</span>) { <span class="type"><a href="qpainter.html">QPainter</a></span> painter(<span class="keyword">this</span>); <span class="type"><a href="qstyleoptionfocusrect.html">QStyleOptionFocusRect</a></span> option; option<span class="operator">.</span>initFrom(<span class="keyword">this</span>); option<span class="operator">.</span>backgroundColor <span class="operator">=</span> palette()<span class="operator">.</span>color(<span class="type"><a href="qpalette.html">QPalette</a></span><span class="operator">::</span>Background); style()<span class="operator">-</span><span class="operator">></span>drawPrimitive(<span class="type"><a href="qstyle.html">QStyle</a></span><span class="operator">::</span>PE_FrameFocusRect<span class="operator">,</span> <span class="operator">&</span>option<span class="operator">,</span> <span class="operator">&</span>painter<span class="operator">,</span> <span class="keyword">this</span>); }</pre> <p>Example using QStylePainter:</p> <pre class="cpp"> <span class="type">void</span> MyWidget<span class="operator">::</span>paintEvent(<span class="type"><a href="qpaintevent.html">QPaintEvent</a></span> <span class="operator">*</span> <span class="comment">/* event */</span>) { <span class="type">QStylePainter</span> painter(<span class="keyword">this</span>); <span class="type"><a href="qstyleoptionfocusrect.html">QStyleOptionFocusRect</a></span> option; option<span class="operator">.</span>initFrom(<span class="keyword">this</span>); option<span class="operator">.</span>backgroundColor <span class="operator">=</span> palette()<span class="operator">.</span>color(<span class="type"><a href="qpalette.html">QPalette</a></span><span class="operator">::</span>Background); painter<span class="operator">.</span>drawPrimitive(<span class="type"><a href="qstyle.html">QStyle</a></span><span class="operator">::</span>PE_FrameFocusRect<span class="operator">,</span> option); }</pre> </div> <p><b>See also </b><a href="qstyle.html">QStyle</a> and <a href="qstyleoption.html">QStyleOption</a>.</p> <!-- @@@QStylePainter --> <div class="func"> <h2>Member Function Documentation</h2> <!-- $$$QStylePainter[overload1]$$$QStylePainter --> <h3 class="fn"><a name="QStylePainter"></a>QStylePainter::<span class="name">QStylePainter</span> ()</h3> <p>Constructs a <a href="qstylepainter.html">QStylePainter</a>.</p> <!-- @@@QStylePainter --> <!-- $$$QStylePainter$$$QStylePainterQWidget* --> <h3 class="fn"><a name="QStylePainter-2"></a>QStylePainter::<span class="name">QStylePainter</span> ( <span class="type"><a href="qwidget.html">QWidget</a></span> * <i>widget</i> )</h3> <p>Construct a <a href="qstylepainter.html">QStylePainter</a> using widget <i>widget</i> for its paint device.</p> <!-- @@@QStylePainter --> <!-- $$$QStylePainter$$$QStylePainterQPaintDevice*QWidget* --> <h3 class="fn"><a name="QStylePainter-3"></a>QStylePainter::<span class="name">QStylePainter</span> ( <span class="type"><a href="qpaintdevice.html">QPaintDevice</a></span> * <i>pd</i>, <span class="type"><a href="qwidget.html">QWidget</a></span> * <i>widget</i> )</h3> <p>Construct a <a href="qstylepainter.html">QStylePainter</a> using <i>pd</i> for its paint device, and attributes from <i>widget</i>.</p> <!-- @@@QStylePainter --> <!-- $$$begin[overload1]$$$beginQWidget* --> <h3 class="fn"><a name="begin"></a><span class="type">bool</span> QStylePainter::<span class="name">begin</span> ( <span class="type"><a href="qwidget.html">QWidget</a></span> * <i>widget</i> )</h3> <p>Begin painting operations on the specified <i>widget</i>.
