How to clear the old selected item, when new one is selected

deleted286

I have a function that, give the selected items

void Widget::on_tableWidget_itemDoubleClicked(QTableWidgetItem *item)

When i change the item, the old item doesnt clear,

i've tried the below code, but it doesnt let me any item because it clears the selection immediately

void Widget::on_tableWidget_itemSelectionChanged()
{

ui->tableWidget->clearSelection();
  
}

What is the solution of it?

Get selected items using https://doc.qt.io/qt-5/qtablewidget.html#selectedItems, iterate over them and call https://doc.qt.io/qt-5/qtablewidgetitem.html#setSelected on all of them except the item passed to on_tableWidget_itemDoubleClicked.

@jsulm im getting selected items in that way

QList<QTableWidgetItem*> MySelList = ui->tableWidget->selectedItems();
      for (QTableWidgetItem* item : MySelList)
      {

          scln = QString::fromStdU16String(item->text().toStdU16String());
         qDebug() << scln;
           
}

@suslucoder Did you read my post?

@suslucoder have you tried setSelectionMode(QAbstractItemView::SingleSelection); on your table widget? Seems like you try to implement behaviour that's already there.
