[mythtv] MythPopupBox losing focus

   okay, I have a solution that does the job for MythPopupBox. It 
dynamically generates a QPtrList with the QButton widgets we possible 
want to cycle through (thus ignoring QLabels and stuff).

   However, in case of MythDialog there are more widgets that can have 
user interaction. But what widgets should I check for??? Or should I 
cycle through all the widgets exept QLabel,...???

   Is there a better solution than the dynamic_cast hack to find out 
what kind of widget I'm dealing with?

any suggestions?

regards, Philippe

         // Recursively generate list of all children
         QObjectList *l = queryList(NULL,NULL,false,true);
         QObjectListIt it(*l); // iterate over all the children

         // Generate list of all widgets we want to cycle through
         widgetList = new QPtrList<QWidget>();
         while ((objs = it.current()) != 0)
         {
             if (dynamic_cast<QButton*>(objs))
             {

                 if(widget->hasFocus())
                     selected=widgetList->count();
                 widgetList->append(widget);
             }
             ++it;
         }
         delete l; // delete the list, not the objects
