c++ - qt, using freeglut, error with 'glutInit' -

i've been trying utilize freeglut in qt project. unfortunately when utilize glut function 'glutwiresphere' or 'glutwiretorus' error:

freeglut error: function called without first calling 'glutinit'.

and when seek run application quits itself. don't know should phone call 'glutinit'. i've installed freeglut according tutorial:

i've figured out. quite simple actualy. needed utilize 'glutinit( & argc, argv )' in main.cpp this:

int main(int argc, char *argv[]) { glutinit( & argc, argv ); qapplication a(argc, argv); mainwindow w; w.show(); homecoming a.exec(); }

c++ qt opengl glut freeglut
