SetCurrent text of comboBox

[A Former User]

ui->Lista->addItem(Nome_Config_nuovo);

How can I do to set the new item as current Item?

[mrjj]

well you can use setCurrentIndex(int index)
the last inserted have count() -1 as index

@mrjj

 ui->Lista_Configurazione->addItem(Nome_Config_nuovo);
       ui->Lista_Configurazione->setCurrentIndex(-1);

I wrote this but it doesn't work, the current item is empty

That is because you have setCurrentIndex(-1). What do you expect it to set as the current item in such a circumstance, especially since https://doc.qt.io/qt-5/qcombobox.html#currentIndex-prop states:

By default, for an empty combo box or a combo box in which no current item is set, this property has a value of -1.

Come on, think about it first, @mrjj wrote:

the last inserted have count() -1 as index

ui->Lista_Configurazione->setCurrentIndex(ui->Lista_Configurazione->count() - 1);

means the last item in the list (i.e. the one you have just added), doesn't it?
