Regular expressions follow the Qt Regex syntax, which is formulated after the Perl Regex syntax. A more detailed overview of the possible rules can be found at: http://doc.qt.io/qt-4.8/qregexp.html If a required option is present, even the double-click on the interface will first start the options dialog (Qt only) Required fields are marked bold and put first in the dialog. Additionally if validation failes (which it will if a required field is kept empty, but also if a non-required textfield is violating the defined regex), the label of the field is marked with red.
