Get the Contents of a QComboBox

I need to get an QStringList or an array containing all QStrings in a QComboBox.

I can't find a QComboBox method that does this, in fact I can't even find a QAbstractItemModel method that does this.

Is this really my only option:

std::vector< QString > list( myQComboBox.count() );

for( auto i = 0; i < list.size(); i++ )
{
    list[i] = myQComboBox.itemText( i );
}
Solution

  • QAbstractItemModel can contain images, trees other kinds of data that can be kept in QVariant. That is why you can't get a QStringList from it. It is pointless.

    However, there is a class QStringListModel inherited from QAbstractItemModel that is intended to keep strings. And as you can expect it has method stringList().

    QComboBox allows you to change a default model which it uses to another one. By default it uses QStandardItemModel. Change it to a string list model after creating the combo box.

     QStringListModel* cbModel = new QStringListModel();
 comboBox->setModel(cbModel);

    Now you can get what you want:

    QStringList list = cbModel->stringList();
