Bug 2955. Workaround for lack of atomic operations in GCCE standard libraries (fall back to default use of Mutex)
<html><center><h2>Gradients</h2></center><p>In this demo we show the various types of gradients that canbe 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 definesthe colors in the gradient. The three topmost controls determine the red,green and blue components while the last defines the alpha of thegradient. You can move points, and add new ones, by clicking with the leftmouse button, and remove points by clicking with the right button.</p><p>There are three default configurations available at the bottom ofthe page that are provided as suggestions on how a color table could beconfigured.</p></html>
