<P>
<p>The <a href="QLineF.html#QLineF()"><tt>QLineF</tt></a> class provides a two-dimensional vector using floating point precision.</p>
<p>A <a href="QLineF.html#QLineF()"><tt>QLineF</tt></a> describes a finite length line (or line segment) on a two-dimensional surface. <a href="QLineF.html#QLineF()"><tt>QLineF</tt></a> defines the start and end points of the line using floating point accuracy for coordinates. Use the <a href="QLineF.html#toLine()"><tt>toLine</tt></a> function to retrieve an integer based copy of this line.</p>
<p><table align="center" cellpadding="2" cellspacing="1" border="0">
<tr valign="top" class="odd"><td><img src="%2E%2E/images/qline-point.png" /></td><td><img src="%2E%2E/images/qline-coordinates.png" /></td></tr>
</table></p>
<p>The positions of the line's start and end points can be retrieved using the <a href="QLineF.html#p1()"><tt>p1</tt></a>, <a href="QLineF.html#x1()"><tt>x1</tt></a>, <a href="QLineF.html#y1()"><tt>y1</tt></a>, <a href="QLineF.html#p2()"><tt>p2</tt></a>, <a href="QLineF.html#x2()"><tt>x2</tt></a>, and <a href="QLineF.html#y2()"><tt>y2</tt></a> functions. The <a href="QLineF.html#dx()"><tt>dx</tt></a> and <a href="QLineF.html#dy()"><tt>dy</tt></a> functions return the horizontal and vertical components of the line, respectively.</p>
<p>The line's length can be retrieved using the <a href="QLineF.html#length()"><tt>length</tt></a> function, and altered using the <a href="QLineF.html#setLength(double)"><tt>setLength</tt></a> function. Use the <a href="QLineF.html#isNull()"><tt>isNull</tt></a> function to determine whether the <a href="QLineF.html#QLineF()"><tt>QLineF</tt></a> represents a valid line or a null line.</p>
<p>The intersect() function determines the <a href="QLineF.html#IntersectType-enum"><tt>IntersectType</tt></a> for this line and a given line, while the <a href="QLineF.html#angle(com.trolltech.qt.gui.QLineF)"><tt>angle</tt></a> function returns the angle between the lines. In addition, the <a href="QLineF.html#unitVector()"><tt>unitVector</tt></a> function returns a line that has the same starting point as this line, but with a length of only 1, while the <a href="QLineF.html#normalVector()"><tt>normalVector</tt></a> function returns a line that is perpendicular to this line with the same starting point and length.</p>
<p>Finally, the line can be translated a given offset using the <a href="QLineF.html#translate(double, double)"><tt>translate</tt></a> function, and can be traversed using the <a href="QLineF.html#pointAt(double)"><tt>pointAt</tt></a> function.</p>
