|

| 32 | In this demo we show the various types of gradients that can
|
|---|
| 33 | be used in Qt.
|
|---|
| 34 |

|
|---|
| 37 | There are three types of gradients:
|
|---|
| 38 |
|
|---|
| 39 | \list
|
|---|
| 40 | \o \bold{Linear} gradients interpolate colors between start and end points.
|
|---|
| 41 | \o \bold{Radial} gradients interpolate colors between a focal point and the
|
|---|
| 42 | points on a circle surrounding it.
|
|---|
| 43 | \o \bold{Conical} gradients interpolate colors around a center point.
|
|---|
| 44 | \endlist
|
|---|
| 45 |
|
|---|
| 46 | The panel on the right contains a color table editor that defines
|
|---|
| 47 | the colors in the gradient. The three topmost controls determine the red,
|
|---|
| 48 | green and blue components while the last defines the alpha of the
|
|---|
| 49 | gradient. You can move points, and add new ones, by clicking with the left
|
|---|
| 50 | mouse button, and remove points by clicking with the right button.
|
|---|
| 51 |
|
|---|
| 52 | There are three default configurations available at the bottom of
|
|---|
| 53 | the page that are provided as suggestions on how a color table could be
|
|---|
| 54 | configured.
