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.

Member Function Documentation

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 160 of file KChartPalette.cpp.

void KChart::Palette::changed ( )
signal

Emitted whenever the palette changes.

Views listen to this and repaing.

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 105 of file KChartPalette.cpp.

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 170 of file KChartPalette.cpp.

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 150 of file KChartPalette.cpp.

void Palette::removeBrush ( int  position)

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

Definition at line 176 of file KChartPalette.cpp.

int Palette::size ( ) const
Returns
the number of brushed in the palette.

Definition at line 155 of file KChartPalette.cpp.
