I'm making simple TODO-list in Qt, i want to "check" done items by changing their background color to green. I was looking for many hours but i only found how to change the hilight color. Can someone help me?

@EDIT

OMG, I'm sorry I forgot to write, I'm using QTreeWidget, I was trying to set the pointer to QTreeWidgetItem with

QTreeWidgetItem* ch = new QTreeWidgetItem();
ch = ui->TaskList->selectedItems();
ch->setBackground(0, Qt::green);

but it's not working.

I know how to set background on NEW item,

QTreeWidgetItem* tItem = new QTreeWidgetItem();
tItem->setText(0,ui->lineEdit->text());
tItem->setBackground(0, Qt::red);

@EDIT2

OK, I get how to do it

QList<QTreeWidgetItem*> ch;
ch = ui->TaskList->selectedItems();
foreach(QTreeWidgetItem * ch_item, ch)
ch_item->setBackground(0, Qt::green);

Without knowing what kind of objects you're using for your "items", it's not possible to answer your question. – goug Feb 02 '17 at 02:23

put in some code example – Prashanth Benny Feb 02 '17 at 05:18
Are you just selecting them to set them done or do you use the checkbox ? If so you can set the background in a stylesheet based on that property and you don't need to apply the background manually anymore. – ymoreau Jul 19 '17 at 07:32
