Not exactly. updateGL() updates your application in the sense that it calls 
drawGL(), where you perform the drawing to the offscreen buffer or update 
any animations. And then it swaps the buffers by calling 
QGLWidget::swapBuffers(), if autoBufferSwap is set to true.

glutSwapBuffers() just swaps the two buffers and it is equivalent to 
QGLWidget::swapBuffers().

At least that is my understanding after reading the documentation for 
QGLWidget.
