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 true 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">QPoint</span> p; p<span class="operator">.</span><a href="qpoint.html#setX">setX</a>(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">QPoint</span>(<span class="number">1</span><span class="operator">,</span> <span class="number">0</span>); p<span class="operator">.</span><a href="qpoint.html#rx">rx</a>()<span class="operator">+</span><span class="operator">+</span>;</pre> <p>A QPoint object can also be used as a vector: Addition and subtraction are defined as for vectors (each component is added separately). A QPoint object can also be divided or multiplied by an <tt>int</tt> or a <tt>qreal</tt>.</p> <p>In addition, the QPoint class provides the <a href="qpoint.html#manhattanLength">manhattanLength</a>() function which gives an inexpensive approximation of the length of the QPoint object interpreted as a vector.
