<class name="QGradient" doc="/**
&lt;p&gt;The &lt;a href=&quot;QGradient.html#QGradient()&quot;&gt;&lt;tt&gt;QGradient&lt;/tt&gt;&lt;/a&gt; class is used in combination with &lt;a href=&quot;QBrush.html&quot;&gt;&lt;tt&gt;QBrush&lt;/tt&gt;&lt;/a&gt; to specify gradient fills.&lt;/p&gt;
&lt;p&gt;Qt currently supports three types of gradient fills:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;i&gt;Linear&lt;/i&gt; gradients interpolate colors between start and end points.&lt;/li&gt;
&lt;li&gt;&lt;i&gt;Radial&lt;/i&gt; gradients interpolate colors between a focal point and end points on a circle surrounding it.&lt;/li&gt;
&lt;li&gt;&lt;i&gt;Conical&lt;/i&gt; gradients interpolate colors around a center point.&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;A gradient's type can be retrieved using the &lt;a href=&quot;QGradient.html#type()&quot;&gt;&lt;tt&gt;type&lt;/tt&gt;&lt;/a&gt; function. Each of the types is represented by a subclass of &lt;a href=&quot;QGradient.html#QGradient()&quot;&gt;&lt;tt&gt;QGradient&lt;/tt&gt;&lt;/a&gt;:&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/qgradient-linear.png&quot; /&gt;&lt;/td&gt;&lt;td&gt;&lt;img src=&quot;%2E%2E/images/qgradient-radial.png&quot; /&gt;&lt;/td&gt;&lt;td&gt;&lt;img src=&quot;%2E%2E/images/qgradient-conical.png&quot; /&gt;&lt;/td&gt;&lt;/tr&gt;
&lt;thead&gt;&lt;tr valign=&quot;top&quot; class=&quot;qt-style&quot;&gt;&lt;th&gt;&lt;a href=&quot;QLinearGradient.html&quot;&gt;&lt;tt&gt;QLinearGradient&lt;/tt&gt;&lt;/a&gt;&lt;/th&gt;&lt;th&gt;&lt;a href=&quot;QRadialGradient.html&quot;&gt;&lt;tt&gt;QRadialGradient&lt;/tt&gt;&lt;/a&gt;&lt;/th&gt;&lt;th&gt;&lt;a href=&quot;QConicalGradient.html&quot;&gt;&lt;tt&gt;QConicalGradient&lt;/tt&gt;&lt;/a&gt;&lt;/th&gt;&lt;/tr&gt;&lt;/thead&gt;
&lt;/table&gt;&lt;/p&gt;
&lt;p&gt;The colors in a gradient is defined using stop points of the QGradientStop type, i.e&amp;#x2e; a position and a color. Use the &lt;a href=&quot;QGradient.html#setColorAt(double, com.trolltech.qt.gui.QColor)&quot;&gt;&lt;tt&gt;setColorAt&lt;/tt&gt;&lt;/a&gt; function to define a single stop point. Alternatively, use the &lt;a href=&quot;QGradient.html#setStops(com.trolltech.qt.gui.QColor&gt;&gt;)&quot;&gt;&lt;tt&gt;setStops&lt;/tt&gt;&lt;/a&gt; function to define several stop points in one go. Note that the latter function &lt;i&gt;replaces&lt;/i&gt; the current set of stop points.&lt;/p&gt;
&lt;p&gt;It is the gradient's complete set of stop points (accessible through the &lt;a href=&quot;QGradient.html#stops()&quot;&gt;&lt;tt&gt;stops&lt;/tt&gt;&lt;/a&gt; function) that describes how the gradient area should be filled. If no stop points have been specified, a gradient of black at 0 to white at 1 is used.&lt;/p&gt;
&lt;p&gt;A diagonal linear gradient from black at (100, 100) to white at (200, 200) could be specified like this:&lt;/p&gt;
&lt;pre&gt;        QLinearGradient linearGrad(QPointF(100, 100), QPointF(200, 200));
        linearGrad.setColorAt(0, Qt::black);
        linearGrad.setColorAt(1, Qt::white);&lt;/pre&gt;
&lt;p&gt;A gradient can have an arbitrary number of stop points. The following would create a radial gradient starting with red in the center, blue and then green on the edges:&lt;/p&gt;
&lt;pre&gt;        QRadialGradient radialGrad(QPointF(100, 100), 100);
        radialGrad.setColorAt(0, Qt::red);
        radialGrad.setColorAt(0.5, Qt::blue);
        radialGrad.setColorAt(1, Qt::green);&lt;/pre&gt;
&lt;p&gt;It is possible to repeat or reflect the gradient outside its area by specifiying the spread method&lt;/tt&gt; using the &lt;a href=&quot;QGradient.html#setSpread(com.trolltech.qt.gui.QGradient.Spread)&quot;&gt;&lt;tt&gt;setSpread&lt;/tt&gt;&lt;/a&gt; function. The default is to pad the outside area with the color at the closest stop point. The currently set spread method&lt;/tt&gt; can be retrieved using the &lt;a href=&quot;QGradient.html#spread()&quot;&gt;&lt;tt&gt;spread&lt;/tt&gt;&lt;/a&gt; function. The QGradient::Spread enum defines three different methods:&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/qradialgradient-pad.png&quot; /&gt;&lt;/td&gt;&lt;td&gt;&lt;img src=&quot;%2E%2E/images/qradialgradient-repeat.png&quot; /&gt;&lt;/td&gt;&lt;td&gt;&lt;img src=&quot;%2E%2E/images/qradialgradient-reflect.png&quot; /&gt;&lt;/td&gt;&lt;/tr&gt;
&lt;tr valign=&quot;top&quot; class=&quot;even&quot;&gt;&lt;td&gt;PadSpread&lt;/td&gt;&lt;td&gt;RepeatSpread&lt;/td&gt;&lt;td&gt;ReflectSpread&lt;/td&gt;&lt;/tr&gt;
&lt;/table&gt;&lt;/p&gt;
&lt;p&gt;Note that the &lt;a href=&quot;QGradient.html#setSpread(com.trolltech.qt.gui.QGradient.Spread)&quot;&gt;&lt;tt&gt;setSpread&lt;/tt&gt;&lt;/a&gt; function only has effect for linear and radial gradients. The reason is that the conical gradient is closed by definition, i.e&amp;#x2e; the &lt;i&gt;conical&lt;/i&gt; gradient fills the entire circle from 0 - 360 degrees, while the boundary of a radial or a linear gradient can be specified through its radius or final stop points, respectively.&lt;/p&gt;
