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.
