详细描述

A flat color legend

The class visualizes a ColorVector together with a scale (axis) and a caption. ColorLegends are vertical or horizontal.

构造及析构函数说明

ColorLegend()

ColorLegend::ColorLegend

(

)

Constructs a legend object with an axis at the left side

The legend resides in the top-right area and has no caption. Scale numbering is shown.

Sets the legend title string

参数

s	Title text string

成员函数说明

draw()

void ColorLegend::draw ( )

overridevirtual

Draws the color legend

Renders the color legend including color bar, axis, and caption.

setAutoScale()

void ColorLegend::setAutoScale

(

bool

val

)

Enables or disables auto-scaling

参数

val	True to enable auto-scaling, false to disable

setLimits()

void ColorLegend::setLimits	(	double	start,

majors

)

Sets number of major intervals

参数

majors

Number of major intervals

setMinors()

void ColorLegend::setMinors

(

int

minors

)

Sets number of minor intervals

参数

minors

Number of minor intervals

setOrientation()

void ColorLegend::setOrientation	(	ORIENTATION	orientation,
		SCALEPOSITION	pos
	)

Sets the legend orientation and axis scale position

参数

orientation	Legend orientation (BottomTop or TopBottom)

setRelPosition()

void ColorLegend::setRelPosition	(	Qwt3D::Tuple	relMin,
		Qwt3D::Tuple	relMax
	)

Sets relative position of the legend within the plot area

参数
