Thank you for your time Andreas, I have always received excellent advice from 
you.

Now that I have promoted the frame widget it is no longer displayed on the 
main window. I think I understand why but I haven't been able to make the 
frame display from my frame class.

The following compiles without error and the paint event is called so I think 
I must be close to the answer.

#include "myframe.h"
#include <QtDebug>

MyFrame::MyFrame(QWidget *parent)
 : QFrame(parent)
{
/*
  The following has been copied from ui_MainWindow.h.
  Do I need something like this here?

  mapFrame = new MyFrame(centralwidget);
  mapFrame->setObjectName(QString::fromUtf8("mapFrame"));
  mapFrame->setGeometry(QRect(30, 160, 731, 241));
  mapFrame->setFrameShape(QFrame::StyledPanel);
  mapFrame->setFrameShadow(QFrame::Raised);
*/
}

MyFrame::~MyFrame()
{
}

void MyFrame::paintEvent(QPaintEvent *)
{
  qDebug() << "paint event called" << endl;

  QPainter paint(this);
  paintMap(&paint);
}

void MyFrame::paintMap(QPainter *p)
{
  p->drawText(0,0,"text");
  qDebug() << "paint map called" << endl;
}
