Model sorting vs. selection

[VlJE]

Hello! After the sorting of my model (derived from the abstract table model, my own file model) the selection on my table view remains on the (now false) place. The problem: my selection is on the view and my sorting is in the model.
I thought it should work automatically in the view to keep the selection of indexes and not of cells by sorting my model.
What can You recommend?

void FileModel::sort ( int column, Qt::SortOrder order )
{
 
   bool (*compare_funk)(const BUFileInfo &a,const BUFileInfo &b)=0; //point to the compare-function
   switch (column)
   {
   case 0:
	   compare_funk=(order)?BUFileInfo::biggerName:BUFileInfo::lessName;
       break;
   case 1:
	   compare_funk=(order)?BUFileInfo::biggerSize:BUFileInfo::lessSize;
       break;
   case 2:
	   compare_funk=(order)?BUFileInfo::biggerExt:BUFileInfo::lessExt;
       break;
   case 3:
	   compare_funk=(order)?BUFileInfo::biggerDate:BUFileInfo::lessDate;
       break;
   case 4:
	   compare_funk=(order)?BUFileInfo::biggerState:BUFileInfo::lessState;
       break;
   }
 
   if(compare_funk)
   {
	   //std::list<BUFileInfo>::sort(fileList.begin(),fileList.end(),compare_funk);
	   qSort(fileList.begin(),fileList.end(),compare_funk);
	emit layoutChanged();
 
   }
 
}

void FileModel::sort ( int column, Qt::SortOrder order )
{
  
   bool (*compare_funk)(const BUFileInfo &a,const BUFileInfo &b)=0; //point to the compare-function
   switch (column)
   {
   case 0:

       break;

       break;
   case 4:
	   compare_funk=(order)?BUFileInfo::biggerState:BUFileInfo::lessState;
       break;
   }

   if(compare_funk)
   {
	   //std::list<BUFileInfo>::sort(fileList.begin(),fileList.end(),compare_funk);
	   qSort(fileList.begin(),fileList.end(),compare_funk);
