<!-- $$$QPen-description -->
<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qpen.html">QPen</a> class defines how a <a href="qpainter.html">QPainter</a> should draw lines and outlines of shapes.</p>
<p>A pen has a <a href="qpen.html#style">style</a>(), <a href="qpen.html#width">width</a>(), <a href="qpen.html#brush">brush</a>(), <a href="qpen.html#capStyle">capStyle</a>() and <a href="qpen.html#joinStyle">joinStyle</a>().</p>
<p>The pen style defines the line type. The brush is used to fill strokes generated with the pen. Use the <a href="qbrush.html">QBrush</a> class to specify fill styles. The cap style determines the line end caps that can be drawn using <a href="qpainter.html">QPainter</a>, while the join style describes how joins between two lines are drawn. The pen width can be specified in both integer (<a href="qpen.html#width">width</a>()) and floating point (<a href="qpen.html#widthF">widthF</a>()) precision. A line width of zero indicates a cosmetic pen. This means that the pen width is always drawn one pixel wide, independent of the <a href="qpainter.html#coordinate-transformations">transformation</a> set on the painter.</p>
<p>The various settings can easily be modified using the corresponding <a href="qpen.html#setStyle">setStyle</a>(), <a href="qpen.html#setWidth">setWidth</a>(), <a href="qpen.html#setBrush">setBrush</a>(), <a href="qpen.html#setCapStyle">setCapStyle</a>() and <a href="qpen.html#setJoinStyle">setJoinStyle</a>() functions (note that the painter's pen must be reset when altering the pen's properties).</p>
<p>For example:</p>
<pre class="cpp">
<span class="type"><a href="qpainter.html">QPainter</a></span> painter(<span class="keyword">this</span>);
<span class="type"><a href="qpen.html#QPen">QPen</a></span> pen(<span class="type">Qt</span><span class="operator">::</span>green<span class="operator">,</span> <span class="number">3</span><span class="operator">,</span> <span class="type">Qt</span><span class="operator">::</span>DashDotLine<span class="operator">,</span> <span class="type">Qt</span><span class="operator">::</span>RoundCap<span class="operator">,</span> <span class="type">Qt</span><span class="operator">::</span>RoundJoin);
painter<span class="operator">.</span>setPen(pen);
</pre>
<p>which is equivalent to</p>
<pre class="cpp">
<span class="type"><a href="qpainter.html">QPainter</a></span> painter(<span class="keyword">this</span>);
<span class="type"><a href="qpen.html#QPen">QPen</a></span> pen; <span class="comment">// creates a default pen</span>
pen<span class="operator">.</span>setStyle(<span class="type">Qt</span><span class="operator">::</span>DashDotLine);
pen<span class="operator">.</span>setWidth(<span class="number">3</span>);
pen<span class="operator">.</span>setBrush(<span class="type">Qt</span><span class="operator">::</span>green);
pen<span class="operator">.</span>setCapStyle(<span class="type">Qt</span><span class="operator">::</span>RoundCap);
pen<span class="operator">.</span>setJoinStyle(<span class="type">Qt</span><span class="operator">::</span>RoundJoin);
painter<span class="operator">.</span>setPen(pen);
</pre>
<p>The default pen is a solid black brush with 1 width, square cap style (<a href="../qtcore/qt.html#PenCapStyle-enum">Qt::SquareCap</a>), and bevel join style (<a href="../qtcore/qt.html#PenJoinStyle-enum">Qt::BevelJoin</a>).</p>
<p>In addition <a href="qpen.html">QPen</a> provides the <a href="qpen.html#color">color</a>() and <a href="qpen.html#setColor">setColor</a>() convenience functions to extract and set the color of the pen's brush, respectively. Pens may also be compared and streamed.</p>
<p>For more information about painting in general, see the <a href="paintsystem.html">Paint System</a> documentation.</p>
<a name="pen-style"></a>
<h3 id="pen-style">Pen Style</h3>
<p>Qt provides several built-in styles represented by the <a href="../qtcore/qt.html#PenStyle-enum">Qt::PenStyle</a> enum:</p>
<div class="table"><table class="generic">
<tr valign="top" class="odd"><td ><img src="images/qpen-solid.png" alt="" /></td><td ><img src="images/qpen-dash.png" alt="" /></td><td ><img src="images/qpen-dot.png" alt="" /></td></tr>
<tr valign="top" class="even"><td ><a href="../qtcore/qt.html#PenStyle-enum">Qt::SolidLine</a></td><td ><a href="../qtcore/qt.html#PenStyle-enum">Qt::DashLine</a></td><td ><a href="../qtcore/qt.html#PenStyle-enum">Qt::DotLine</a></td></tr>
<tr valign="top" class="odd"><td ><img src="images/qpen-dashdot.png" alt="" /></td><td ><img src="images/qpen-dashdotdot.png" alt="" /></td><td ><img src="images/qpen-custom.png" alt="" /></td></tr>
<tr valign="top" class="even"><td ><a href="../qtcore/qt.html#PenStyle-enum">Qt::DashDotLine</a></td><td ><a href="../qtcore/qt.html#PenStyle-enum">Qt::DashDotDotLine</a></td><td ><a href="../qtcore/qt.html#PenStyle-enum">Qt::CustomDashLine</a></td></tr>
</table></div>
<p>Simply use the <a href="qpen.html#setStyle">setStyle</a>() function to convert the pen style to either of the built-in styles, except the <a href="../qtcore/qt.html#PenStyle-enum">Qt::CustomDashLine</a> style which we will come back to shortly. Setting the style to <a href="../qtcore/qt.html#PenStyle-enum">Qt::NoPen</a> tells the painter to not draw lines or outlines. The default pen style is <a href="../qtcore/qt.html#PenStyle-enum">Qt::SolidLine</a>.</p>
<p>Since Qt 4.1 it is also possible to specify a custom dash pattern using the <a href="qpen.html#setDashPattern">setDashPattern</a>() function which implicitly converts the style of the pen to <a href="../qtcore/qt.html#PenStyle-enum">Qt::CustomDashLine</a>. The pattern argument, a <a href="../qtcore/qvector.html">QVector</a>, must be specified as an even number of <a href="../qtcore/qtglobal.html#qreal-typedef">qreal</a> entries where the entries 1, 3, 5... are the dashes and 2, 4, 6... are the spaces. For example, the custom pattern shown above is created using the following code:</p>
<pre class="cpp">
<span class="type"><a href="qpen.html#QPen">QPen</a></span> pen;
<span class="type"><a href="../qtcore/qvector.html">QVector</a></span><span class="operator"><</span><span class="type"><a href="../qtcore/qtglobal.html#qreal-typedef">qreal</a></span><span class="operator">></span> dashes;
<span class="type"><a href="../qtcore/qtglobal.html#qreal-typedef">qreal</a></span> space <span class="operator">=</span> <span class="number">4</span>;
dashes <span class="operator"><</span><span class="operator"><</span> <span class="number">1</span> <span class="operator"><</span><span class="operator"><</span> space <span class="operator"><</span><span class="operator"><</span> <span class="number">3</span> <span class="operator"><</span><span class="operator"><</span> space <span class="operator"><</span><span class="operator"><</span> <span class="number">9</span> <span class="operator"><</span><span class="operator"><</span> space
<span class="operator"><</span><span class="operator"><</span> <span class="number">27</span> <span class="operator"><</span><span class="operator"><</span> space <span class="operator"><</span><span class="operator"><</span> <span class="number">9</span> <span class="operator"><</span><span class="operator"><</span> space;
pen<span class="operator">.</span>setDashPattern(dashes);
</pre>
<p>Note that the dash pattern is specified in units of the pens width, e.g. a dash of length 5 in width 10 is 50 pixels long.</p>
<p>The currently set dash pattern can be retrieved using the <a href="qpen.html#dashPattern">dashPattern</a>() function. Use the <a href="qpen.html#isSolid">isSolid</a>() function to determine whether the pen has a solid fill, or not.</p>
<a name="cap-style"></a>
<h3 id="cap-style">Cap Style</h3>
<p>The cap style defines how the end points of lines are drawn using <a href="qpainter.html">QPainter</a>. The cap style only apply to wide lines, i.e. when the width is 1 or greater. The <a href="../qtcore/qt.html#PenCapStyle-enum">Qt::PenCapStyle</a> enum provides the following styles:</p>
<div class="table"><table class="generic">
<tr valign="top" class="odd"><td ><img src="images/qpen-square.png" alt="" /></td><td ><img src="images/qpen-flat.png" alt="" /></td><td ><img src="images/qpen-roundcap.png" alt="" /></td></tr>
<tr valign="top" class="even"><td ><a href="../qtcore/qt.html#PenCapStyle-enum">Qt::SquareCap</a></td><td ><a href="../qtcore/qt.html#PenCapStyle-enum">Qt::FlatCap</a></td><td ><a href="../qtcore/qt.html#PenCapStyle-enum">Qt::RoundCap</a></td></tr>
</table></div>
<p>The <a href="../qtcore/qt.html#PenCapStyle-enum">Qt::SquareCap</a> style is a square line end that covers the end point and extends beyond it by half the line width. The <a href="../qtcore/qt.html#PenCapStyle-enum">Qt::FlatCap</a> style is a square line end that does not cover the end point of the line. And the <a href="../qtcore/qt.html#PenCapStyle-enum">Qt::RoundCap</a> style is a rounded line end covering the end point.</p>
<p>The default is <a href="../qtcore/qt.html#PenCapStyle-enum">Qt::SquareCap</a>.</p>
<p>Whether or not end points are drawn when the pen width is 0 or 1 depends on the cap style. Using <a href="../qtcore/qt.html#PenCapStyle-enum">Qt::SquareCap</a> or <a href="../qtcore/qt.html#PenCapStyle-enum">Qt::RoundCap</a> they are drawn, using <a href="../qtcore/qt.html#PenCapStyle-enum">Qt::FlatCap</a> they are not drawn.</p>
<a name="join-style"></a>
<h3 id="join-style">Join Style</h3>
<p>The join style defines how joins between two connected lines can be drawn using <a href="qpainter.html">QPainter</a>. The join style only apply to wide lines, i.e. when the width is 1 or greater. The <a href="../qtcore/qt.html#PenJoinStyle-enum">Qt::PenJoinStyle</a> enum provides the following styles:</p>
<div class="table"><table class="generic">
<tr valign="top" class="odd"><td ><img src="images/qpen-bevel.png" alt="" /></td><td ><img src="images/qpen-miter.png" alt="" /></td><td ><img src="images/qpen-roundjoin.png" alt="" /></td></tr>
<tr valign="top" class="even"><td ><a href="../qtcore/qt.html#PenJoinStyle-enum">Qt::BevelJoin</a></td><td ><a href="../qtcore/qt.html#PenJoinStyle-enum">Qt::MiterJoin</a></td><td ><a href="../qtcore/qt.html#PenJoinStyle-enum">Qt::RoundJoin</a></td></tr>
</table></div>
<p>The <a href="../qtcore/qt.html#PenJoinStyle-enum">Qt::BevelJoin</a> style fills the triangular notch between the two lines. The <a href="../qtcore/qt.html#PenJoinStyle-enum">Qt::MiterJoin</a> style extends the lines to meet at an angle. And the <a href="../qtcore/qt.html#PenJoinStyle-enum">Qt::RoundJoin</a> style fills a circular arc between the two lines.</p>
<p>The default is <a href="../qtcore/qt.html#PenJoinStyle-enum">Qt::BevelJoin</a>.</p>
<p class="centerAlign"><img src="images/qpen-miterlimit.png" alt="" /></p><p>When the <a href="../qtcore/qt.html#PenJoinStyle-enum">Qt::MiterJoin</a> style is applied, it is possible to use the <a href="qpen.html#setMiterLimit">setMiterLimit</a>() function to specify how far the miter join can extend from the join point. The <a href="qpen.html#miterLimit">miterLimit</a>() is used to reduce artifacts between line joins where the lines are close to parallel.</p>
<p>The <a href="qpen.html#miterLimit">miterLimit</a>() must be specified in units of the pens width, e.g. a miter limit of 5 in width 10 is 50 pixels long. The default miter limit is 2, i.e. twice the pen width in pixels.</p>

<p>The dash pattern is specified in units of the pens width; e.g. a dash of length 5 in width 10 is 50 pixels long. Note that a pen with zero width is equivalent to a cosmetic pen with a width of 1 pixel.</p>
<p>Each dash is also subject to cap styles so a dash of 1 with square cap set will extend 0.5 pixels out in each direction resulting in a total width of 2.</p>
<p>Note that the default cap style is <a href="../qtcore/qt.html#PenCapStyle-enum">Qt::SquareCap</a>, meaning that a square line end covers the end point and extends beyond it by half the line width.</p>
