+ − <p>In this demo we show the various types of gradients that can+ −
be used in Qt.</p>+ −
+ − <p>There are three types of gradients:+ −
+ − <ul>+ −
<li><b>Linear</b> gradients interpolate colors between start and end+ −
points.</li>+ −
<li><b>Radial</b> gradients interpolate colors between a focal point and the+ −
points on a circle surrounding it.</li>+ −
<li><b>Conical</b> gradients interpolate colors around a center point.</li>+ −
</ul>+ −
+ − </p>+ −
+ − <p>The panel on the right contains a color table editor that defines+ −
the colors in the gradient. The three topmost controls determine the red,+ −
green and blue components while the last defines the alpha of the+ −
gradient. You can move points, and add new ones, by clicking with the left+ −
mouse button, and remove points by clicking with the right button.</p>+ −
+ − <p>There are three default configurations available at the bottom of+ −
the page that are provided as suggestions on how a color table could be+ −
configured.</p>+ −
