The main widget for the dialog-page. This class does not contain any application logic, but instead delegates the logic to another object (a logic-object) through signals emitted via the interface of this class. The interface allows the widget or logic to be independently re-factored without affecting the other. This widget extends the existing makVrv::DtLoaderSettingsWidget by adding a new checkbox which (when checked/unchecked) enables/disables the Flip DDS checkbox already existing in the base class.
