Well, OK. My problem is that I would like to connect up to the
textChanged(const QString &) signal emitted by the spinbox's lineedit.
signal, however, is only emitted when the edit is modified directly, not
when it changes indirectly eg. by pressing the up/down arrows on the
spinbox. Any suggestions for a solution?
