    <a href="qcolor.html">QColor</a>
    may be used whenever a
    <a href="qpen.html">QPen</a>
    is expected.</p>
  <p>The QPen 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>
    QPainter painter(this);
    QPen pen(Qt.green, 3, Qt.DashDotLine, Qt.RoundCap. Qt.RoundJoin);
    painter.setPen(pen);
</pre>
<p>which is equivalent to</p>
<pre>
    QPainter painter(this);
    QPen pen();  // creates a default pen

    pen.setStyle(Qt.DashDotLine);
    pen.setWidth(3);
    pen.setBrush(Qt.green);
    pen.setCapStyle(Qt.RoundCap);
    pen.setJoinStyle(Qt.RoundJoin);

    painter.setPen(pen);
</pre>
<p>The default pen is a solid black brush with 0 width, square cap style (<a href="qt.html#PenCapStyle-enum">Qt.SquareCap</a>), and bevel join style (<a href="qt.html#PenJoinStyle-enum">Qt.BevelJoin</a>).</p>
<p>In addition QPen 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>

<h3>Pen Style</h3>
<p>Qt provides several built-in styles represented by the <a href="qt.html#PenStyle-enum">Qt.PenStyle</a> enum:</p>
<table align="center" border="0" cellpadding="2" cellspacing="1">
<tr bgcolor="#F0F0F0" valign="top">
<td><img src="images/qpen-solid.png" /></td>
<td><img src="images/qpen-dash.png" /></td>
<td><img src="images/qpen-dot.png" /></td>
</tr>
<tr bgcolor="#E0E0E0" valign="top">
<td><a href="qt.html#PenStyle-enum">Qt.SolidLine</a></td>
<td><a href="qt.html#PenStyle-enum">Qt.DashLine</a></td>
<td><a href="qt.html#PenStyle-enum">Qt.DotLine</a></td>
</tr>
<tr bgcolor="#F0F0F0" valign="top">
<td><img src="images/qpen-dashdot.png" /></td>
<td><img src="images/qpen-dashdotdot.png" /></td>
<td><img src="images/qpen-custom.png" /></td>
</tr>
<tr bgcolor="#E0E0E0" valign="top">
<td><a href="qt.html#PenStyle-enum">Qt.DashDotLine</a></td>
<td><a href="qt.html#PenStyle-enum">Qt.DashDotDotLine</a></td>
<td><a href="qt.html#PenStyle-enum">Qt.CustomDashLine</a></td>
</tr>
</table>
<br />
<br />
<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="qt.html#PenStyle-enum">Qt.CustomDashLine</a> style which we will come back to shortly. Setting the style to <a href="qt.html#PenStyle-enum">Qt.NoPen</a> tells the painter to not draw lines or outlines. The default pen style is <a href="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="qt.html#PenStyle-enum">Qt.CustomDashLine</a>. The pattern argument, a <a href="qvector.html">QVector</a>, must be specified as an even number of <a href="qtcore.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>
    QPen pen;
    QVector&lt;qreal&gt; dashes;
    qreal space = 4;

    dashes &lt;&lt; 1 &lt;&lt; space &lt;&lt; 3 &lt;&lt; space &lt;&lt; 9 &lt;&lt; space
               &lt;&lt; 27 &lt;&lt; space &lt;&lt; 9;

    pen.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 id="cap-style" name="cap-style" />
<h3>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="qt.html#PenCapStyle-enum">Qt.PenCapStyle</a> enum provides the following styles:</p>
<table align="center" border="0" cellpadding="2" cellspacing="1">
<tr bgcolor="#F0F0F0" valign="top">
<td><img src="images/qpen-square.png" /></td>
<td><img src="images/qpen-flat.png" /></td>
<td><img src="images/qpen-roundcap.png" /></td>
</tr>
<tr bgcolor="#E0E0E0" valign="top">
<td><a href="qt.html#PenCapStyle-enum">Qt.SquareCap</a></td>
<td><a href="qt.html#PenCapStyle-enum">Qt.FlatCap</a></td>
<td><a href="qt.html#PenCapStyle-enum">Qt.RoundCap</a></td>
</tr>
</table>
<br />
<br />
<p>The <a href="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="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="qt.html#PenCapStyle-enum">Qt.RoundCap</a> style is a rounded line end covering the end point.</p>
<p>The default is <a href="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="qt.html#PenCapStyle-enum">Qt.SquareCap</a> or <a href="qt.html#PenCapStyle-enum">Qt.RoundCap</a> they are drawn, using <a href="qt.html#PenCapStyle-enum">Qt.FlatCap</a> they are not drawn.</p>
<a id="join-style" name="join-style" />
<h3>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="qt.html#PenJoinStyle-enum">Qt.PenJoinStyle</a> enum provides the following styles:</p>
<table align="center" border="0" cellpadding="2" cellspacing="1">
<tr bgcolor="#F0F0F0" valign="top">
<td><img src="images/qpen-bevel.png" /></td>
<td><img src="images/qpen-miter.png" /></td>
<td><img src="images/qpen-roundjoin.png" /></td>
</tr>
<tr bgcolor="#E0E0E0" valign="top">
<td><a href="qt.html#PenJoinStyle-enum">Qt.BevelJoin</a></td>
<td><a href="qt.html#PenJoinStyle-enum">Qt.MiterJoin</a></td>
<td><a href="qt.html#PenJoinStyle-enum">Qt.RoundJoin</a></td>
</tr>
</table>
<br />
<br />
<p>The <a href="qt.html#PenJoinStyle-enum">Qt.BevelJoin</a> style fills the triangular notch between the two lines. The <a href="qt.html#PenJoinStyle-enum">Qt.MiterJoin</a> style extends the lines to meet at an angle. And the <a href="qt.html#PenJoinStyle-enum">Qt.RoundJoin</a> style fills a circular arc between the two lines.</p>
<p>The default is <a href="qt.html#PenJoinStyle-enum">Qt.BevelJoin</a>.</p>
<p align="center"><img src="images/qpen-miterlimit.png" /></p>
<p>When the <a href="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>See also <a href="qpen.html#capStyle">capStyle</a>() and <a href="qpen.html#cap-style">Cap Style</a>.</p>
<h3 class="fn"><a name="setColor" />QPen.setColor (<i>self</i>, <a href="qcolor.html">QColor</a>&#160;<i>color</i>)</h3><p>Sets the color of this pen's brush to the given <i>color</i>.</p>

<h3 class="fn"><a name="setDashPattern" />QPen.setDashPattern (<i>self</i>, float-list&#160;<i>pattern</i>)</h3><p>Sets the dash pattern for this pen to the given <i>pattern</i>. This implicitly converts the style of the pen to <a href="qt.html#PenStyle-enum">Qt.CustomDashLine</a>.</p>
<p>The pattern must be specified as an even number of entries where the entries 1, 3, 5... are the dashes and 2, 4, 6... are the spaces. For example:</p>
<table align="center" border="0" cellpadding="2" cellspacing="1" width="100%">
<tr bgcolor="#F0F0F0" valign="top">
<td><img src="images/qpen-custom.png" /></td>
<td>
<pre>
    QPen pen;
    QVector&lt;qreal&gt; dashes;
    qreal space = 4;
    dashes &lt;&lt; 1 &lt;&lt; space &lt;&lt; 3 &lt;&lt; space &lt;&lt; 9 &lt;&lt; space
               &lt;&lt; 27 &lt;&lt; space &lt;&lt; 9;
    pen.setDashPattern(dashes);
</pre></td>
</tr>
</table>
<br />
<br />
<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. 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>

<h3 class="fn"><a name="setJoinStyle" />QPen.setJoinStyle (<i>self</i>, <a href="qt.html#PenJoinStyle-enum">Qt.PenJoinStyle</a>&#160;<i>pcs</i>)</h3><p>Sets the pen's join style to the given <i>style</i>. The default value is <a href="qt.html#PenJoinStyle-enum">Qt.BevelJoin</a>.</p>
<p>See also <a href="qpen.html#joinStyle">joinStyle</a>() and <a href="qpen.html#join-style">Join Style</a>.</p>
<h3 class="fn"><a name="setMiterLimit" />QPen.setMiterLimit (<i>self</i>, float&#160;<i>limit</i>)</h3><p>Sets the miter limit of this pen to the given <i>limit</i>.</p>
<p align="center"><img src="images/qpen-miterlimit.png" /></p>
<p>The miter limit describes how far a miter join can extend from the join point. This is used to reduce artifacts between line joins where the lines are close to parallel.</p>
<p>This value does only have effect when the pen style is set to <a href="qt.html#PenJoinStyle-enum">Qt.MiterJoin</a>. The value is specified in units of the pen's 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>

<h3 class="fn"><a name="setStyle" />QPen.setStyle (<i>self</i>, <a href="qt.html#PenStyle-enum">Qt.PenStyle</a>)</h3><p>Sets the pen style to the given <i>style</i>.</p>
<p>See the <a href="qt.html#PenStyle-enum">Qt.PenStyle</a> documentation for a list of the available styles. 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="qt.html#PenStyle-enum">Qt.CustomDashLine</a>.</p>

<h3 class="fn"><a name="setWidth" />QPen.setWidth (<i>self</i>, int&#160;<i>width</i>)</h3><p>Sets the pen width to the given <i>width</i> with integer point precision.</p>
<p>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>Setting a pen width with a negative value is not supported.</p>
