I made an STL map that use the widget text name as the key to retrieve my QWidgetTagPair class (QRadioButton* +  MyObject* ).  

It is more work than I was used to as Microsoft widgets have a Tag object property that you use to associate with your data object.  As a lazy programmer I wanted to make sure I had not missed a similar existing approach in QT.  Thank you for your help.
