Which version of Qt are you using? The Qt 3 QSpinbox has a function
interpretText() that should be called whenever the user manually edits
the contents of the spinbox. I think that this function should do the
right thing by default (i.e. call mapTextToValue(), but you could
always subclass QSpinbox and reimplement interpretText to do what you
want.

If you could post a small sample script showing the behaviour, I'm sure
I cold help you find a solution.
