Detailed Description

A flat color legend.

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

Member Function Documentation

◆ absolutePosition()

QRectF Qwt3DColorLegend::absolutePosition ( ) const

返回绝对像素位置

Returns: 绝对像素矩形

◆ draw()

void Qwt3DColorLegend::draw ( const Qwt3DRenderContext & ctx )

overridevirtual

Draws the color legend using VBO + polygon/line shaders.

Parameters

ctx	Render context providing shaders, matrices, and coordinate conversion

Renders the color bar as a set of quads using VBO + polygon shader, the border outline using VBO + line shader, then delegates axis and caption drawing to their respective draw() methods.

Reimplemented from Qwt3DDrawable.

◆ drawScale()

bool Qwt3DColorLegend::drawScale ( ) const

返回是否绘制刻度

Returns: true 如果绘制刻度

◆ limits()

void Qwt3DColorLegend::limits	(	double &	start,
		double &	stop
	)		const

返回刻度范围

Parameters

[out]	start	起始值
[out]	stop	终止值

◆ majors()

int Qwt3DColorLegend::majors ( ) const

返回主刻度数

Returns: 主刻度数

◆ minors()

int Qwt3DColorLegend::minors ( ) const

返回次刻度数

Returns: 次刻度数

◆ orientation()

Qwt3DColorLegend::ORIENTATION Qwt3DColorLegend::orientation ( ) const

返回图例方向

Returns: ORIENTATION 枚举值

◆ scalePosition()

Qwt3DColorLegend::SCALEPOSITION Qwt3DColorLegend::scalePosition ( ) const

返回刻度位置

Returns: SCALEPOSITION 枚举值

◆ titleString()

QString Qwt3DColorLegend::titleString ( ) const

返回图例标题文本

Returns: 标题字符串

◆ useAbsolutePosition()

bool Qwt3DColorLegend::useAbsolutePosition ( ) const

返回是否使用绝对定位

Returns: true 如果使用绝对像素坐标定位
