/><h2>Detailed Description</h2><p>This class can be pickled.</p><p>The QPolygon class provides a vector of points using integer
precision.</p>
<p>A QPolygon object is a <a href="qvector.html">QVector</a><<a href="qpoint.html">QPoint</a>>.
The easiest way to add points to a QPolygon is to use <a href="qvector.html">QVector</a>'s streaming operator, as illustrated
below:</p>
<pre class="cpp">
<span class="type">QPolygon</span> polygon;
polygon <span class="operator"><</span><span class="operator"><</span> <span class="type"><a href="qpoint.html">QPoint</a></span>(<span class="number">10</span><span class="operator">,</span> <span class="number">20</span>) <span class="operator"><</span><span class="operator"><</span> <span class="type"><a href="qpoint.html">QPoint</a></span>(<span class="number">20</span><span class="operator">,</span> <span class="number">30</span>);
</pre>
<p>In addition to the functions provided by <a href="qvector.html">QVector</a>, QPolygon provides some point-specific
functions.</p>
<p>Each point in a polygon can be retrieved by passing its index to
the <a href="qpolygon.html#point">point</a>() function. To populate
the polygon, QPolygon provides the <a href="qpolygon.html#setPoint">setPoint</a>() function to set the point
at a given index, the <a href="qpolygon.html#setPoints">setPoints</a>() function to set all the
points in the polygon (resizing it to the given number of points),
and the <a href="qpolygon.html#putPoints">putPoints</a>() function
which copies a number of given points into the polygon from a
specified index (resizing the polygon if necessary).</p>
<p>QPolygon provides the <a href="qpolygon.html#boundingRect">boundingRect</a>() and <a href="qpolygon.html#translate">translate</a>() functions for geometry
functions. Use the <a href="qmatrix.html#map">QMatrix.map</a>()
function for more general transformations of QPolygons.</p>
<p>The QPolygon class is <a href="implicit-sharing.html#implicit-data-sharing">implicitly
shared</a>.</p>

<h3 class="fn"><a name="prepend" />QPolygon.prepend (<i>self</i>, <a href="qpoint.html">QPoint</a> <i>value</i>)</h3><h3 class="fn"><a name="putPoints" />QPolygon.putPoints (<i>self</i>, int <i>index</i>, int <i>firstx</i>, int <i>firsty</i>, ...)</h3><p>Copies <i>nPoints</i> points from the variable argument list

<p>The points are given as a sequence of integers, starting with
<i>firstx</i> then <i>firsty</i>, and so on. The polygon is resized
if <tt>index+nPoints</tt> exceeds its current size.</p>
<p>The example code creates a polygon with three points (4,5),
(6,7) and (8,9), by expanding the polygon from 1 to 3 points:</p>
<pre class="cpp">
<span class="type"><a href="qpolygon.html">QPolygon</a></span> polygon(<span class="number">1</span>);
polygon<span class="operator">[</span><span class="number">0</span><span class="operator">]</span> <span class="operator">=</span> <span class="type"><a href="qpoint.html">QPoint</a></span>(<span class="number">4</span><span class="operator">,</span> <span class="number">5</span>);
polygon<span class="operator">.</span>putPoints(<span class="number">1</span><span class="operator">,</span> <span class="number">2</span><span class="operator">,</span> <span class="number">6</span><span class="operator">,</span><span class="number">7</span><span class="operator">,</span> <span class="number">8</span><span class="operator">,</span><span class="number">9</span>);
</pre>
<p>The following code has the same result, but here the putPoints()
function overwrites rather than extends:</p>
<pre class="cpp">

<h3 class="fn"><a name="setPoints-2" />QPolygon.setPoints (<i>self</i>, int <i>firstx</i>, int <i>firsty</i>, ...)</h3><p>This is an overloaded function.</p>
<p>Resizes the polygon to <i>nPoints</i> and populates it with the
points specified by the variable argument list. The points are
given as a sequence of integers, starting with <i>firstx</i> then
<i>firsty</i>, and so on.</p>
<p>The example code creates a polygon with two points (10, 20) and
(30, 40):</p>

polygon.</p>
<p>Set operations on polygons will treat the polygons as areas.
Non-closed polygons will be treated as implicitly closed.</p>
<p>This function was introduced in Qt 4.3.</p>
<h3 class="fn"><a name="swap" />QPolygon.swap (<i>self</i>, <a href="qpolygon.html">QPolygon</a> <i>other</i>)</h3><p>Swaps polygon <i>other</i> with this polygon. This operation is
very fast and never fails.</p>
<p>This function was introduced in Qt 4.8.</p>
<h3 class="fn"><a name="translate" />QPolygon.translate (<i>self</i>, int <i>dx</i>, int <i>dy</i>)</h3><p>Translates all points in the polygon by (<i>dx</i>,

<p>Set operations on polygons, will treat the polygons as areas,
and implicitly close the polygon.</p>
