如何在Qcombobox中获取Qcomplete的文本

QComboBox *comboBox = new QComboBox;
QCompleter *completer = new QCompleter;
comboBox->setCompleter(completer);

QStringListModel *model = new QStringListModel;
completer->setModel(model);

QStringList texts;
texts << "Apple" << "Banana" << "Orange";
model->setStringList(texts);

QString text = comboBox->currentText();

#include <QtWidgets>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QComboBox *comboBox = new QComboBox;
    QCompleter *completer = new QCompleter;
    comboBox->setCompleter(completer);

    QStringListModel *model = new QStringListModel;
    completer->setModel(model);

    QStringList texts;
    texts << "Apple" << "Banana" << "Orange";
    model->setStringList(texts);

    QObject::connect(comboBox, QOverload<int>::of(&QComboBox::currentIndexChanged), [=](int index){
        QString text = comboBox->currentText();
        qDebug() << "Selected text: " << text;
    });

    comboBox->show();

    return app.exec();
}
