Detailed Description

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

The palette class encapsulates a colletion 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.

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

Adds brush to the palette. If no position is specified, the brush is appended. Referenced by makeDefaultPalette(), makeRainbowPalette(), and makeSubduedPalette().

const Palette& KDChart::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. Referenced by KDChart::AttributesModel::headerData().

QBrush KDChart::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. Referenced by KDChart::AttributesModel::headerData(), and makeRainbowPalette().

bool KDChart::Palette::isValid (   )  const

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

Palette& KDChart::Palette::operator= (  const Palette &   )

const Palette& KDChart::Palette::rainbowPalette (   )  [static]

Referenced by KDChart::AttributesModel::headerData().

void KDChart::Palette::removeBrush (  int  position  )

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

int KDChart::Palette::size (   )  const
