With it as a wrapper we can register any QObject to use widget based field mechanism from QWizard. It also helps to avoid the necessity for inheritance to just adjust the text property of a widget. Can not remove the TextCheckBox, because it is used in some old C++ wizards. Change-Id: I85a85a834714a4b38b501c13357fa8c8bb02b5bd Reviewed-by: Tim Jenssen <tim.jenssen@qt.io>
