Detailed Description

A Qt string or an output device dependent string.

Qwt3DLabel provides text rendering on 3D plots, supporting both Qt string representation and device-dependent string output.

Member Function Documentation

draw()

void Qwt3DLabel::draw ( const Qwt3DRenderContext &  ctx )

overridevirtual

Draws the label using a texture quad with GLSL text shader.

Parameters

ctx	Render context providing shaders, matrices, and coordinate conversion

Renders the text to a QImage, creates an OpenGL texture, and draws a textured quad using VBO + text.vert/text.frag shaders. For gl2ps vector export (deviceFonts mode), falls back to drawDeviceText.

Reimplemented from Qwt3DDrawable.

setColor() [1/2]

void Qwt3DLabel::setColor ( double  r, double  g, double  b, double  a = 1  )

overridevirtual

Reimplemented from Qwt3DDrawable.

setColor() [2/2]

void Qwt3DLabel::setColor ( RGBA  rgba )

overridevirtual

Reimplemented from Qwt3DDrawable.

string()

QString Qwt3DLabel::string

(

)

const

返回标签文本

Returns

当前标签文本字符串
