Detailed Description

A slider who’s groove displays an LCH color gradient.

GradientSlider

The groove of this slider that displays a gradient between two LCH colors. The gradient is an equal gradient calculated independently for each of the four components (lightness, chroma, hue, alpha).

The hue component is the only one that is circular (0° = 360°): Here, Here, the path via the shorter side is always chosen. Examples:

  • If the first hue is 182° and the second hue is 1°, than the hue will increase from 182° up to 359°, than 0° and then 1°.
  • If the first hue is 169° and the second hue is 359°, than the hue will decrease from 169° down to 0°, and then 359°.

This widget considers the alpha channel, using a background of gray squares behind the (semi-)transparent colors.

Example:

L C h alpha
firstColorCieLchD50A 80% 5 15° 0.7
70% 7 0.8
60% 9 355° 0.9
secondColorCieLchD50A 50% 11 345° 1.0

Note that due to this mathematical model, there might be out-of-gamut colors within the slider even if both, the first and the second color are in-gamut colors. Out-of-gamut colors are rendered as nearby in-gamut colors.

Orientation of the widget.

By default, the orientation is horizontal. The possible orientations are Qt::Horizontal and Qt::Vertical.

Also, Qt::Orientation is declared in this header as type to Qt’s type system: Q_DECLARE_METATYPE(Qt::Orientation). This is done because Qt itself does not declare this type as meta type. Because we use it here in a property including a signal, we have to declare this type. Depending on your use case (for example if you want to use it reliably in Qt’s signals and slots), you might consider calling qRegisterMetaType() for this type, once you have a QApplication object.
