How to set CurrentText of QComboBox?

[Engelard]

I want to set the text of this widget when no item selected yet. At the beginning my comboBox is empty, then in runtime program adds elements to this box, and i want instantly display in comboBox some string("Elemens inside"+QString::number(i)). But i can't find proper function.

The

ui->comboBox->setCurrentText(QString::number(i));

or:

ui->comboBox->setWindowTitle(QString::number(i));

is not working, i don't know why...

P.S. i dont need change text of first item, i need only set initial text of the header of that box.

You want to set the text in an editable QComboBox's QLineEdit widget to some string, right? In what way does ui->comboBox->setCurrentText(QString::number(i)); not work? Please be precise.

is your Combobox editable? if not, setCurrentText will have no effect

The setter setCurrentText() simply calls setEditText() if the combo box is editable. Otherwise, if there is a matching text in the list, currentIndex is set to the corresponding index.
