Searching bar in tree widget

[deleted286]

I have the code below for searching items in tree widget. I doesnt search. When i finish editing, i cant see any item on widget.
It doesnt have any error. But when i debug, i saw that "arama" is empty

void MainWindow::on_ara_editingFinished()
{

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

@suslucoder What does ui->ara->text() return? In which column do you want to search? Is there at least one item in the tree widget in the column you're searching containing the text ui->ara->text() returns?

@jsulm
I've changed my code to

   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::red);
    }

but setCurrentItem is set one item..of course...

But i want to see every item that contains the given text

@jsulm you suggest me to use setSelected ?

[jsulm]

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

[deleted286]

@jsulm No, i dont want to select :D
I have a search bar, it doesnt set the contains this is my problem

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?

[deleted286]

@jsulm yes i dont i know why im using it.
I saw in somewehere.
But when i delete it, it doesnt work

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

[deleted286]

@jsulm when i delete

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

the hole code doesnt work. without any error messages

[deleted286]

@suslucoder I debug and, it finds the items but doesnt show me on tree widget

Hi,

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

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

search doesnt work

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
