    @suslucoder Yes, I do - you want to select items, right? The method I suggested does exactly that...

        Then can you please explain what you want to do with items you found? Because I don't understand...

          @suslucoder

          QList<QTreeWidgetItem*> arama = ui->treeWidget2->findItems(ui->ara->text(), Qt::MatchContains|Qt::MatchRecursive, 0);
              for(QTreeWidgetItem* item  : arama)
              {
                ui->treeWidget2->setCurrentItem(item, 0);  
               // item->setBackground(0, Qt::cyan);
          
              }
          

          when i comment item->setBackground(0, Qt::cyan);, unless the tree has more than 1 item that at give via ara->text, it show the exactly 1 item.

          When i un comment the

          item->setBackground(0, Qt::cyan);
          

          the code finds the every item that contains the text, but the text setCurrent item has is blue, the other one is cyan.

          When i only wrote

          item->setBackground(0, Qt::cyan);
          

          search doesnt work

            @suslucoder Why do you call setCurrentItem?

                In what way it doesn't work? setBackground should work without setCurrentItem, they are unrelated.

                      Hi,

                      Why don't you just modify the background of each item of the list and nothing else ?

                        I think arguement for setBackground is QBrush not the color
                        void QTreeWidgetItem::setBackground(int column, const QBrush &brush)

                            @SGaist when i modify the background, for highligting the searching items,
                            even the text was changed, it keep the oldest item.

                            I search for a and highligh its background.
                            Then i delete a, search for b

                            It shows me the both a and b

                              @Christian-Ehrlicher thanks for the correction.

                              @suslucoder it's showing old search items with different color because you have set it's background color in last search..
                              It's better to set all with default color and matched items in highlight colour for each search
