@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

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

@jsulm when i delete

ui->treeWidget2->setCurrentItem(item, 0);

the hole code doesnt work. without any error messages

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)

Can you please elaborate this?

@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
