<!-- $$$QPoint-description -->
<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qpoint.html">QPoint</a> class defines a point in the plane using integer precision.</p>
<p>A point is specified by a x coordinate and an y coordinate which can be accessed using the <a href="qpoint.html#x">x</a>() and <a href="qpoint.html#y">y</a>() functions. The <a href="qpoint.html#isNull">isNull</a>() function returns <code>true</code> if both x and y are set to 0. The coordinates can be set (or altered) using the <a href="qpoint.html#setX">setX</a>() and <a href="qpoint.html#setY">setY</a>() functions, or alternatively the <a href="qpoint.html#rx">rx</a>() and <a href="qpoint.html#ry">ry</a>() functions which return references to the coordinates (allowing direct manipulation).</p>
<p>Given a point <i>p</i>, the following statements are all equivalent:</p>
<pre class="cpp">
<span class="type"><a href="qpoint.html#QPoint">QPoint</a></span> p;
p<span class="operator">.</span>setX(p<span class="operator">.</span>x() <span class="operator">+</span> <span class="number">1</span>);
p <span class="operator">+</span><span class="operator">=</span> <span class="type"><a href="qpoint.html#QPoint">QPoint</a></span>(<span class="number">1</span><span class="operator">,</span> <span class="number">0</span>);
p<span class="operator">.</span>rx()<span class="operator">+</span><span class="operator">+</span>;
</pre>
<p>A <a href="qpoint.html">QPoint</a> object can also be used as a vector: Addition and subtraction are defined as for vectors (each component is added separately). A <a href="qpoint.html">QPoint</a> object can also be divided or multiplied by an <code>int</code> or a <code>qreal</code>.</p>
<p>In addition, the <a href="qpoint.html">QPoint</a> class provides the <a href="qpoint.html#manhattanLength">manhattanLength</a>() function which gives an inexpensive approximation of the length of the <a href="qpoint.html">QPoint</a> object interpreted as a vector. Finally, <a href="qpoint.html">QPoint</a> objects can be streamed as well as compared.</p>

<!-- $$$manhattanLength[overload1]$$$manhattanLength -->
<h3 class="fn" id="manhattanLength"><a name="manhattanLength"></a><span class="type">int</span> QPoint::<span class="name">manhattanLength</span>() const</h3>
<p>Returns the sum of the absolute values of <a href="qpoint.html#x">x</a>() and <a href="qpoint.html#y">y</a>(), traditionally known as the "Manhattan length" of the vector from the origin to the point. For example:</p>
<pre class="cpp">
<span class="type"><a href="qpoint.html#QPoint">QPoint</a></span> oldPosition;
MyWidget<span class="operator">::</span>mouseMoveEvent(<span class="type"><a href="../qtgui/qmouseevent.html">QMouseEvent</a></span> <span class="operator">*</span>event)
{
<span class="type"><a href="qpoint.html#QPoint">QPoint</a></span> point <span class="operator">=</span> event<span class="operator">-</span><span class="operator">></span>pos() <span class="operator">-</span> oldPosition;
<span class="keyword">if</span> (point<span class="operator">.</span>manhattanLength() <span class="operator">></span> <span class="number">3</span>)
<span class="comment">// the mouse has moved more than 3 pixels since the oldPosition</span>
}
</pre>
<p>This is a useful, and quick to calculate, approximation to the true length:</p>
<pre class="cpp">
<span class="type">double</span> trueLength <span class="operator">=</span> std<span class="operator">::</span>sqrt(std<span class="operator">::</span>pow(x()<span class="operator">,</span> <span class="number">2</span>) <span class="operator">+</span> std<span class="operator">::</span>pow(y()<span class="operator">,</span> <span class="number">2</span>));
</pre>
<p>The tradition of "Manhattan length" arises because such distances apply to travelers who can only travel on a rectangular grid, like the streets of Manhattan.</p>
