qt - QHash cannot convert parameter 1 from 'class QHash<class QDomElement,class QDomElement>::const_iterator' to '::iterator' -


i have qhash defined key value pair qdomelement. given below. trying update hash using const_iterator. while doing below error thrown, how resolve same:-

error c2664: 'erase' : cannot convert parameter 1 'class qhash<class qdomelement,class qdomelement>::const_iterator' 'class qhash<class qdomelement,class qdomelemen t>::iterator'

code snippet :-

// update parent child mapping hash     qhash<qdomelement, qdomelement>::const_iterator plist = hashparentchildlist.constbegin();     while (plist != hashparentchildlist.constend())     {         if(plist.key() == element)         {             plist = hashparentchildlist.erase(plist); // error line         }         else         {             plist++;         }     } }

thanks, priyanka

problem solved, use qhash::iterator plist = hashparentchildlist.begin(); instead of qhash::const_iterator plist = hashparentchildlist.constbegin();
