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

[Malyushytsky, Alex]

Have you tried not to call   QTableWidget::closeEditor(editor,hint); ?
According to documentation this function closes editor.
Another approach is you can always reopen it, right?

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

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);
}
