近期遇到一个奇怪的问题,在新安装的Qt 5.3.1 OpenGL 2010 版本号后,每次打开qtcreator之后都会出现一个错误提醒,例如以下图: 最初觉得是显卡驱动没有包括OpenGL2.0 或者更高版本号,可是使用小工具測试以后发现,驱动没有问题。由此推断:此提示信息并不准确。 然后重装了一下qt5.3.1 。发如今装到大约97%的时候。...
首先，创建QApplication实例前先开启Qt::AA_DontCheckOpenGLContextThreadAffinity，有多个context的话还可以考虑开启Qt::AA_ShareOpenGLContexts。其次，QOpenGLContext需要切换到使用线程才可以在那个线程make current，只需要调用其moveToThread即可。当然，context在多个线程间使用需要自行进行同步。
