OpenGL Framebuffer

[^NyAw^]

Hi,

I just copied this code from "framebufferobject" example.

if (!QGLFormat::hasOpenGL() || !QGLFramebufferObject::hasOpenGLFramebufferObjects()) {
    QMessageBox::information(0, "OpenGL framebuffer objects",
                 "This system does not support OpenGL/framebuffer objects.");
        return -1;
    }

if (!QGLFormat::hasOpenGL() || !QGLFramebufferObject::hasOpenGLFramebufferObjects()) {
    QMessageBox::information(0, "OpenGL framebuffer objects",
                 "This system does not support OpenGL/framebuffer objects.");
        return -1;
    }

To copy to clipboard, switch view to plain text mode 

On a notebook it is returning me false on "hasOpenGLFramebufferObjects".

My openGL widget constructor is

QOpenGLWidget::QOpenGLWidget(QWidget *parent) : QGLWidget(QGLFormat(QGL::SampleBuffers),parent)

QOpenGLWidget::QOpenGLWidget(QWidget *parent) : QGLWidget(QGLFormat(QGL::SampleBuffers),parent)

To copy to clipboard, switch view to plain text mode 

I tryied to change it to

QOpenGLWidget::QOpenGLWidget(QWidget *parent) : QGLWidget(QGLFormat(QGL::DirectRendering),parent)

QOpenGLWidget::QOpenGLWidget(QWidget *parent) : QGLWidget(QGLFormat(QGL::DirectRendering),parent)

To copy to clipboard, switch view to plain text mode 

The problem is that the images are not properly shown as you can see on the attached file.
