[Qt-interest] Forbid to close the editor of the QTableWidget

[Iurii Gordiienko]

Hi    Please, help me with solution...    I should implement unique values for all items in one column of the QTableWidget...    I reimplemented the "closeEditor function", I can check the unique values, but I can't forbid to close the editor of that item (Now I don't see any other suitable solution for that). I have a plan to keep in edit-mode (or may be return to old values) while properly values will not be entered...    ----%<------------------------------    void TableWidget::closeEditor( QWidget* editor, QAbstractItemDelegate::EndEditHint hint )    
{    
  QModelIndex idx = currentIndex();    
  if(idx.column()==_uniqueColumn){    
    QLineEdit* p = dynamic_cast<QLineEdit*>(editor);    
    if(p){    
      QString s = p->text();    
    
      //find equal words    
      int row = rowCount();    
      int cur_row = idx.row();    
      for(int i=0;i<row;++i){    
        if(cur_row==i){    
          continue;    
        }    
    
       QTableWidgetItem* p = item(i,_uniqueColumn);    
       if(!p){    
         continue;    
       }    
    
      if(p->data(Qt::DisplayRole).toString()==s){    
        // (bool)edit(idx,QAbstractItemView::AllEditTriggers,0);    
        return;    
      }    
    }    
  }    
    
  QTableWidget::closeEditor(editor,hint);    
}    
    
    ---->%------------------------------        
Qt-4.5.0    
    
Thanks
