<p>In this demo we show the various types of gradients that can
|
|
|
7 |
be used in Qt.</p>
|
|
|

|
|
|

<p>There are three types of gradients:
|
|
|
10 |
|
|
|
11 |
<ul>
|
|
|
12 |
<li><b>Linear</b> gradients interpolate colors between start and end
|
|
|
13 |
points.</li>
|
|
|
14 |
<li><b>Radial</b> gradients interpolate colors between a focal point and the
|
|
|
15 |
points on a circle surrounding it.</li>
|
|
|
16 |
<li><b>Conical</b> gradients interpolate colors around a center point.</li>
|
|
|
17 |
</ul>
|
|
|

|
|

</p>

<p>The panel on the right contains a color table editor that defines
|
|
|
22 |
the colors in the gradient. The three topmost controls determine the red,
|
|
|
23 |
green and blue components while the last defines the alpha of the
|
|
|
24 |
gradient. You can move points, and add new ones, by clicking with the left
|
|
|
25 |
mouse button, and remove points by clicking with the right button.</p>
|
|
|
26 |
|
|
|
27 |
<p>There are three default configurations available at the bottom of
|
|
|
28 |
the page that are provided as suggestions on how a color table could be
|
|
|
29 |
configured.</p>
