<class name="QLine" doc="/**
&lt;p&gt;The &lt;a href=&quot;QLine.html#QLine()&quot;&gt;&lt;tt&gt;QLine&lt;/tt&gt;&lt;/a&gt; class provides a two-dimensional vector using integer precision.&lt;/p&gt;
&lt;p&gt;A &lt;a href=&quot;QLine.html#QLine()&quot;&gt;&lt;tt&gt;QLine&lt;/tt&gt;&lt;/a&gt; describes a finite length line (or a line segment) on a two-dimensional surface. The start and end points of the line are specified using integer point accuracy for coordinates. Use the &lt;a href=&quot;QLineF.html&quot;&gt;&lt;tt&gt;QLineF&lt;/tt&gt;&lt;/a&gt; constructor to retrieve a floating point copy.&lt;/p&gt;
&lt;p&gt;&lt;table align=&quot;center&quot; cellpadding=&quot;2&quot; cellspacing=&quot;1&quot; border=&quot;0&quot;&gt;
&lt;tr valign=&quot;top&quot; class=&quot;odd&quot;&gt;&lt;td&gt;&lt;img src=&quot;%2E%2E/images/qline-point.png&quot; /&gt;&lt;/td&gt;&lt;td&gt;&lt;img src=&quot;%2E%2E/images/qline-coordinates.png&quot; /&gt;&lt;/td&gt;&lt;/tr&gt;
&lt;/table&gt;&lt;/p&gt;
&lt;p&gt;The positions of the line's start and end points can be retrieved using the &lt;a href=&quot;QLine.html#p1()&quot;&gt;&lt;tt&gt;p1&lt;/tt&gt;&lt;/a&gt;, &lt;a href=&quot;QLine.html#x1()&quot;&gt;&lt;tt&gt;x1&lt;/tt&gt;&lt;/a&gt;, &lt;a href=&quot;QLine.html#y1()&quot;&gt;&lt;tt&gt;y1&lt;/tt&gt;&lt;/a&gt;, &lt;a href=&quot;QLine.html#p2()&quot;&gt;&lt;tt&gt;p2&lt;/tt&gt;&lt;/a&gt;, &lt;a href=&quot;QLine.html#x2()&quot;&gt;&lt;tt&gt;x2&lt;/tt&gt;&lt;/a&gt;, and &lt;a href=&quot;QLine.html#y2()&quot;&gt;&lt;tt&gt;y2&lt;/tt&gt;&lt;/a&gt; functions. The &lt;a href=&quot;QLine.html#dx()&quot;&gt;&lt;tt&gt;dx&lt;/tt&gt;&lt;/a&gt; and &lt;a href=&quot;QLine.html#dy()&quot;&gt;&lt;tt&gt;dy&lt;/tt&gt;&lt;/a&gt; functions return the horizontal and vertical components of the line. Use &lt;a href=&quot;QLine.html#isNull()&quot;&gt;&lt;tt&gt;isNull&lt;/tt&gt;&lt;/a&gt; to determine whether the &lt;a href=&quot;QLine.html#QLine()&quot;&gt;&lt;tt&gt;QLine&lt;/tt&gt;&lt;/a&gt; represents a valid line or a null line.&lt;/p&gt;
&lt;p&gt;Finally, the line can be translated a given offset using the &lt;a href=&quot;QLine.html#translate(com.trolltech.qt.core.QPoint)&quot;&gt;&lt;tt&gt;translate&lt;/tt&gt;&lt;/a&gt; function.&lt;/p&gt;
