Detailed Description

A widget for selecting chroma and hue in LCH color space.

This widget displays the plan of chroma and hue (that means a diagram of the radius and the angle of the LCH color space respectively the a axis and the b axis of the Lab color model) at a given lightness.

ChromaHueDiagram

The widget allows the user to select a color (chroma and hue) within the specified gamut at a given lightness. It reacts on mouse events and on keyboard events (see keyPressEvent() for details).

The form of the selection handle (that always indicates the distance from the center of the diagram) and the circular form of the widget, all this helps the user to understand intuitively that he is moving within a polar coordinate system and to capture easily the current radius and angle.

Usage example:

    auto myColorSpace = PerceptualColor::RgbColorSpaceFactory::createSrgb();
    PerceptualColor::ChromaHueDiagram *myDiagram = new PerceptualColor::ChromaHueDiagram(myColorSpace);
    PerceptualColor::GenericColor myColor;
    myColor.third = 270;
    myColor.first = 50;
    myColor.second = 25;
    myDiagram->setCurrentColorCielchD50(myColor);
    myDiagram->show();

Note

This widget always accepts focus by a mouse click within the circle. This happens regardless of the QWidget::focusPolicy property:

If you set the QWidget::focusPolicy property to a value that does not accept focus by mouse click, the focus will nevertheless be accepted for clicks within the actual circle. (This is the default behavior.)
If you set the QWidget::focusPolicy property to a value that accepts focus by mouse click, the focus will not only be accepted for clicks within the actual circle, but also for clicks anywhere within the (rectangular) widget.

Property Documentation

◆ currentColorCielchD50

GenericColor PerceptualColor::ChromaHueDiagram::currentColorCielchD50

readwrite

Currently selected color.

The widget allows the user to change the LCH chroma and the LCH hue values. However, the LCH lightness value cannot be changed by the user, but only by the programmer through this property.

The programmer can set this property to out-of-gamut values; the user cannot.

Constructor & Destructor Documentation

◆ ChromaHueDiagram()

PerceptualColor::ChromaHueDiagram::ChromaHueDiagram	(	const QSharedPointer< PerceptualColor::RgbColorSpace > &	colorSpace,
		QWidget *	parent = nullptr )

explicit

The constructor.

Parameters

colorSpace	The color space within which this widget should operate. Can be created with RgbColorSpaceFactory.
parent	The widget’s parent widget. This parameter will be passed to the base class’s constructor.

Definition at line 41 of file chromahuediagram.cpp.

◆ ~ChromaHueDiagram()

PerceptualColor::ChromaHueDiagram::~ChromaHueDiagram ( )

overridevirtualnoexcept

Default destructor.

Definition at line 75 of file chromahuediagram.cpp.

Member Function Documentation

◆ currentColorCielchD50()

GenericColor PerceptualColor::ChromaHueDiagram::currentColorCielchD50 ( ) const

nodiscard

Getter for property currentColorCielchD50.

Returns: the property currentColorCielchD50

Definition at line 392 of file chromahuediagram.cpp.

◆ currentColorCielchD50Changed

void PerceptualColor::ChromaHueDiagram::currentColorCielchD50Changed ( const PerceptualColor::GenericColor & newCurrentColorCielchD50 )

signal

Notify signal for property currentColorCielchD50.

Parameters

newCurrentColorCielchD50 the new current color

◆ keyPressEvent()

void PerceptualColor::ChromaHueDiagram::keyPressEvent ( QKeyEvent * event )

overrideprotectedvirtual

React on key press events.

Reimplemented from base class.

The keys do not react in form of up, down, left and right like in Cartesian coordinate systems. The keys change radius and angel like in polar coordinate systems, because our color model is also based on a polar coordinate system.

For chroma changes: Moves the handle as much as possible into the desired direction as long as this is still in the gamut.

Qt::Key_Up increments chroma a small step
Qt::Key_Down decrements chroma a small step
Qt::Key_PageUp increments chroma a big step
Qt::Key_PageDown decrements chroma a big step

For hue changes: If necessary, the chroma value is reduced to get an in-gamut color with the new hue.

Qt::Key_Left increments hue a small step
Qt::Key_Right decrements hue a small step
Qt::Key_Home increments hue a big step
Qt::Key_End decrements hue a big step

Parameters

event the event
