QComboBox *comboBox = new QComboBox(this);
comboBox->addItems(QStringList() << "item1" << "item2");
ui->treeWidget->setItemWidget(item, 1, comboBox);

I have used the method like the above code to add the comboBox to some itemWidget in a QtreeWidget. The appearance is not very good when the comboBox always shows.

Is there a method to hide the comboBox and it would appear again when I click that cell? Please give me some help. Thanks.

My current result: enter image description here

What is it you do not like about the result? – eyllanesc
i want to hide the border and the dropDown image before I click that cell. That means those cell would be same as the other cells in general and the comboBox would popup after I clicked that cell. Is it possible to do it? – Ng Clement
You can do that with item delegates. An item delegate displays static content, and when an edit is triggered, replaces it with an editor widget. – king_nak

you can use css

QComboBox{ border:none; } 
QComboBox::down-arrow {image: url(:images/img/blank.png) }
QComboBox::drop-down { background-color:transparent }
