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.

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 156 of file KDChartPalette.cpp.

References changed(), d, QObject::Q_EMIT(), QObject::qobject_cast(), and size().

◆ changed

void KDChart::Palette::changed ( )

signal

Emitted whenever the palette changes. Views listen to this and repaing.

Referenced by addBrush(), and removeBrush().

◆ 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 101 of file KDChartPalette.cpp.

References QObject::qobject_cast().

Referenced by KDChart::Legend::setDefaultColors(), and KDChart::AttributesModel::setPaletteType().

◆ 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 166 of file KDChartPalette.cpp.

References d, isValid(), and size().

◆ 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.

◆ removeBrush()

void Palette::removeBrush ( int position )

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

Definition at line 173 of file KDChartPalette.cpp.

References changed(), d, QObject::Q_EMIT(), QObject::qobject_cast(), and size().

◆ size()

int Palette::size ( ) const

Returns: the number of brushed in the palette.
