The example is meant to show an item delegate with a line edit with
QRegularExpression-based validation depending on type.
Unfortunately, this does not work since QSettings mostly
return QString types.
Fix it to a partially working state by
- Making the expressions match from beginning to end which
was overlooked in the QRegExp->QRegularExpression change.
- Use QCheckBox, QSpinBox for bool/int since it is silly
to have a user edit a bool value by typing 'true'/'false'.
- Move the expressions out to a separate struct to be
able to do some guessing of the type when reading
the QSettings, implement for bool and int.
- Use a fancy Unicode checkmark for displaying bools.
- Fix the garbled display of QByteArray with binary data
by displaying them with hex characters and setting them
read-only.
