Searching bar in tree widget
-
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?

@jsulm yes i dont i know why im using it.
I saw in somewehere.
But when i delete it, it doesnt work@suslucoder said in Searching bar in tree widget:

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

@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 ?

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 bIt 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
