详细描述

Autoscalable axis with caption

Axes are highly customizable especially in terms of labeling and scaling.

构造及析构函数说明

◆ Qwt3DAxis() [1/2]

Qwt3DAxis::Qwt3DAxis ( )

Default constructor

Constructs an uninitialized axis with default parameters.

Destructor

◆ Qwt3DAxis() [2/2]

Qwt3DAxis::Qwt3DAxis	(	Triple	beg,
		Triple	end
	)

Constructs an axis with specified start and end positions

参数

beg	Start position of the axis
end	End position of the axis

成员函数说明

◆ draw()

void Qwt3DAxis::draw ( const Qwt3DRenderContext & ctx )

overridevirtual

Draws the axis including base line, tics, and label

参数

ctx	Render context providing shaders, matrices, and coordinate conversion

Uses VBO + line shader for line geometry. Labels are drawn via Qwt3DLabel::draw() which uses its own texture-based rendering.

重载 Qwt3DDrawable .

◆ labelColor()

RGBA Qwt3DAxis::labelColor ( ) const

返回轴标签颜色

返回: RGBA 颜色值

委托到内部 Qwt3DLabel 的 color() getter（Qwt3DDrawable 的公有 getter）。 setLabelColor() 通过 d->m_label.setColor(col) 设置，此处返回 d->m_label.color()。 Qwt3DDrawable::color 是 protected 成员，Qwt3DAxis 和 Qwt3DLabel 是兄弟关系， C++ 规则下 Qwt3DAxis 不能直接通过 Qwt3DLabel 对象访问 protected 成员，必须使用公有 color() getter。

◆ labelString()

QString Qwt3DAxis::labelString ( ) const

返回轴标签文本

返回: 标签字符串
