C++ 使用Qt-3D和QCustomPlot
我有一个应用程序,需要同时使用和库。但是,当尝试在项目中使用.pro文件中的“QT+=3dinput”编译QCustomPlot时,引用和类时会出现几个错误 我相信这与Qt3DInput引入的类与QtGui模块中的类同名有关,但我对Qt的内部工作机制不够熟悉,无法理解编译器错误试图告诉我的内容 到底是什么导致了这个问题,我如何解决它?对.pro文件或QCustomPlot库本身的修改都是可以接受的 要演示此问题,请使用以下.pro文件编译QCustomPlot:C++ 使用Qt-3D和QCustomPlot,c++,qt,qt5,qcustomplot,qt3d,C++,Qt,Qt5,Qcustomplot,Qt3d,我有一个应用程序,需要同时使用和库。但是,当尝试在项目中使用.pro文件中的“QT+=3dinput”编译QCustomPlot时,引用和类时会出现几个错误 我相信这与Qt3DInput引入的类与QtGui模块中的类同名有关,但我对Qt的内部工作机制不够熟悉,无法理解编译器错误试图告诉我的内容 到底是什么导致了这个问题,我如何解决它?对.pro文件或QCustomPlot库本身的修改都是可以接受的 要演示此问题,请使用以下.pro文件编译QCustomPlot: QT += widgets pr
