详细描述

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.

成员函数说明

draw()

void Qwt3DLabel::draw ( const Qwt3DRenderContext &  ctx )

overridevirtual

Draws the label using a texture quad with GLSL text shader

参数

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.
