@8Observer8 said in QOpenGLFunctions glGetString(GL_EXTENSIONS) is null:
I have a same question. I try to show OpenGL version but I get empty string:
I solved the problem. I activated a second video card on my laptop from code in main.cpp:
#ifdef _WIN32
#include <windows.h>
extern "C" __declspec(dllexport) DWORD NvOptimusEnablement = 0x00000001;
extern "C" __declspec(dllexport) DWORD AmdPowerXpressRequestHighPerformance = 0x00000001;
#endif
#include "Widget.h"
#include <QApplication>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
Widget w;
w.show();
return a.exec();
}
It works too (without QString::fromLatin1):
qDebug() << (const char*)glGetString(GL_VERSION);
