Qt: how to make wide combobox?

Question

Qt

There is a table. In it, we set some settings through the combobox (only selection, no input). We overcame most of the technical problems, stumbled upon another one.
Texts are planned to be quite long (especially in localizations), and I would like to make the drop-down list wide. Approximately like this.

How to implement this in Qt? It is desirable that it also selects its width according to the actual width of the lines.

Answer 1

Here it is suggested to overload the showPopup() method :

void MyComboBox::showPopup()
{
    this->view()->setMinimumWidth(this->view()->sizeHintForColumn(0));
    QComboBox::showPopup();
}
