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
firstColor	80%	5	15°	0.7
	70%	7	5°	0.8
	60%	9	355°	0.9
secondColor	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.

In the case of vertical orientation, firstColor is the colour at the bottom of the widget and secondColor is the colour at the top of the widget.
In the case of horizontal orientation, firstColor is the colour on the left of the widget and secondColor is the colour on the right of the widget in LTR layout. In RTL layout it is the other way round.

Property Documentation

◆ firstColor

PerceptualColor::LchaDouble PerceptualColor::GradientSlider::firstColor

readwrite

First color (the one corresponding to a low value)

See also: READ firstColor() const; WRITE setFirstColor(); NOTIFY firstColorChanged(); secondColor

Definition at line 110 of file gradientslider.h.

◆ orientation

Qt::Orientation PerceptualColor::GradientSlider::orientation

readwrite

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.

See also: READ orientation() const; WRITE setOrientation(); NOTIFY orientationChanged()

Definition at line 129 of file gradientslider.h.

◆ pageStep

qreal PerceptualColor::GradientSlider::pageStep

readwrite

This property holds the page step.

The larger of two natural steps this widget provides. Corresponds to the user pressing PageUp or PageDown.

The valid range is [0, 1].

See also: READ pageStep() const; WRITE setPageStep(); NOTIFY pageStepChanged(); singleStep

Definition at line 142 of file gradientslider.h.

◆ secondColor

PerceptualColor::LchaDouble PerceptualColor::GradientSlider::secondColor

readwrite

Second color (the one corresponding to a high value)

See also: READ secondColor() const; WRITE setSecondColor(); NOTIFY secondColorChanged(); firstColor

Definition at line 150 of file gradientslider.h.

◆ singleStep

qreal PerceptualColor::GradientSlider::singleStep

readwrite

This property holds the single step.

The smaller of two natural steps this widget provides. Corresponds to the user pressing an arrow key.

The valid range is [0, 1].

See also: READ singleStep() const; WRITE setSingleStep(); NOTIFY singleStepChanged(); pageStep

Definition at line 163 of file gradientslider.h.

◆ value

qreal PerceptualColor::GradientSlider::value

readwrite

The slider’s current value.

The valid range is [0, 1]. The slider forces the value to be within the valid range: 0 <= value <= 1.

0 means: totally firstColor()
1 means: totally secondColor()

See also: READ value() const; WRITE setValue(); NOTIFY valueChanged()

Definition at line 177 of file gradientslider.h.

Constructor & Destructor Documentation
