How properly initialize QOpenGLWidget when moving project from opengl to Qt?

[never_ever]

Hi,
I have program where I initialize OpenGL:

void initFunc()
{
    glutInit(&m_argc, m_argv);     //(1)
    glutInitDisplayMode(GLUT_DEPTH | GLUT_RGB | GLUT_DOUBLE);    // (2)
    glutInitWindowSize(m_width, m_height);      //(3)
   //and so on...
}

I know that first(1) and third(3) line I can omit. I use Qt for this. But what with second line (2). If there is some corresponding function to that or I should also skip it.

I know that I can enable for example depth_test by using glEnable(GL_DEPTH_TEST); But if it will be enough? What with other properties like rgb or double?

Hi,

QSufaceFormat is what you are looking for

So I can change second line to:

QSurfaceFormat format;
format.setDepthBufferSize(16);
format.setBlueBufferSize(0);
format.setGreenBufferSize(0);
format.setRedBufferSize(0);
this->setFormat(format);

And if I think right, GLUT_DOUBLE I can change to setStereo(true).
If I have to set all this options or it is default in Qt?

No, setStereo is for stereoscopic view i.e. 3D image one for the left and one for the right eye.

For double buffering, use setSwapBehavior

Oh, thanks, I search for that
