C ++中具有单个openGL上下文的多个QGLWidget [英] Multiple QGLWidgets with a single openGL Context in C++

问题描述

我正在编写一个由多个(16-32)绘图组成的应用程序，这些绘图每秒更新几次，并使用openGL绘制.到现在为止，我已经使用GLUT进行了大部分的样机原型设计.但是，我想采用像QT这样的完整框架，并且我准备编写一个测试QGLWidget.............................................................................................................

I'm writing an application that is composed of multiple (16-32) plots that are updated several times a second and are drawn using openGL. Until now I've down most of the prototyping of the plots with GLUT. However I'd like to adopt a full fledge framework like QT and I'm getting ready to write a test QGLWidget.

在开始之前，我想弄清楚多个QGLWidgets是否可以共享一个openGL上下文?如果是这样，那么在小部件之间共享openGL上下文时，我有什么需要跟踪的细节吗?

Before I get started I'd like to figure out if its possible for multiple QGLWidgets to share a single openGL context? If so is there anything specifics I need to keep track of when sharing an openGL context between widgets?

推荐答案

是的，可以使用

如果有的话，我需要在共享时跟踪任何细节 小部件之间的openGL上下文?

If so is there anything specifics I need to keep track of when sharing an openGL context between widgets?

我不确定，但是我认为没有什么需要特别照顾的.

I am not sure, but I don't think there is anything special you need to take care of.
