Qt 如何在QCustomPlot中启用OpenGL加速?
我的Qt版本是5.12.2。我在.pro文件中添加了DEFINES+=QCUSTOMPLOT\u USE\u OPENGL。My.pro文件如下所示:Qt 如何在QCustomPlot中启用OpenGL加速?,qt,qcustomplot,Qt,Qcustomplot,我的Qt版本是5.12.2。我在.pro文件中添加了DEFINES+=QCUSTOMPLOT\u USE\u OPENGL。My.pro文件如下所示: #------------------------------------------------- # # Project created by QtCreator 2019-04-05T21:23:52 # #------------------------------------------------- QT += core

但当我使用setOpenGl(true)打开OpenGL时,它会不断报告错误:
void QCustomPlot::setOpenGl(bool, int) QCustomPlot can't use OpenGL because QCUSTOMPLOT_USE_OPENGL was not defined during compilation (add 'DEFINES += QCUSTOMPLOT_USE_OPENGL' to your qmake .pro file)
那么,如何在QCustomPlot中启用OpenGL加速功能呢?尝试运行qmake,然后重新生成。我遇到了这个问题,完成这些操作后,一切正常。您可以显示您的.pro。我已经添加了我的.pro文件。请帮我找出问题所在。谢谢!我在Linux中用GCC编译了一个QCustomPlot示例,它对我来说没有任何问题,可能是MSVC的问题,它试图删除构建文件夹并重新编译。是的,我更改了编译器,没有问题。非常感谢。张贴答案。。
