Detailed Description

A Palette is a set of brushes (or colors) to be used for painting data sets.

The palette class encapsulates a collection of brushes, which in the simplest case are colors, to be used for painting a series of data sets. When asked for the m-th color, a palette of size n will wrap around and thus cycle through the available colors.

Three builtin palettes are provided for convenience, one with a default set of colors, one with a subdued color selection, one with rainbow colors.

When a palette changes, it emits a changed() signal. Hook up to it, if you want to repaint when the color selection changes.

Constructor & Destructor Documentation

Palette()

Palette::Palette ( QObject * parent = nullptr )

explicit

Member Function Documentation

addBrush()

void Palette::addBrush	(	const QBrush &	brush,
		int	position = -1 )

Adds brush to the palette.

If no position is specified, the brush is appended.

Definition at line 149 of file KChartPalette.cpp.

changed

void KChart::Palette::changed ( )

signal

Emitted whenever the palette changes.

Views listen to this and repaints.

defaultPalette()

const Palette & Palette::defaultPalette ( )

static

Provide access to the three builtin palettes, one with standard bright colors, one with more subdued colors, and one with rainbow colors.

Definition at line 94 of file KChartPalette.cpp.

getBrush()

QBrush Palette::getBrush

(

int

position

)

const

Query the palette for a brush at the specified position.

If the position exceeds the size of the palette, it wraps around.

Definition at line 159 of file KChartPalette.cpp.

isValid()

bool Palette::isValid

(

)

const

Returns

whether this represents a valid palette. For a palette to be valid it needs to have at least one brush associated.

Definition at line 139 of file KChartPalette.cpp.

operator=()

Palette & Palette::operator=

(

const Palette &

r

)

Definition at line 130 of file KChartPalette.cpp.

rainbowPalette()

const Palette & Palette::rainbowPalette ( )

static

Definition at line 106 of file KChartPalette.cpp.

removeBrush()

void Palette::removeBrush

(

int

position

)

Remove the brush at position position, if there is one.

Definition at line 165 of file KChartPalette.cpp.

size()

int Palette::size

(

)

const

Returns

the number of brushed in the palette.

Definition at line 144 of file KChartPalette.cpp.

subduedPalette()

const Palette & Palette::subduedPalette ( )

static

Definition at line 100 of file KChartPalette.cpp.
