Thank you Jeroen and Laurent for your replies.

It dawned on me within a couple of hours of posting my question where the 
problem was. My solution is probably not overly elegant but it works.

I had a quick look at QinputDialog and I'll experiment with it when I get a 
bit of spare time.

MYDialog *pDialog = new MYDialog;

connect(pDialog->m_ui->elevatuionLineEdit, SIGNAL(textChanged(QString)),
this, SLOT(updateParkElevationSlot(QString)));

This was my first attempt Laurent but it failed with the following error:

"Ui::RotatorDlg* RotatorDlg::m_ui is private within this context"

Plus two other errors.

Defining m_ui as a public variable didn't help.

I'll have another look at this later to see if I can made sense of the error 
messages.

Thanks again.
