如何使用using Qt连接ComboBox和TextBrowser？

#include <QtWidgets>

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

    QWidget window;
    QVBoxLayout layout(&window);

    QComboBox comboBox;
    QTextBrowser textBrowser;

    layout.addWidget(&comboBox);
    layout.addWidget(&textBrowser);

    QObject::connect(&comboBox, QOverload<int>::of(&QComboBox::currentIndexChanged),
                     [&textBrowser](int index){
        textBrowser.append(QString("Selected index: %1").arg(index));
    });

    QStringList items = {"Item 1", "Item 2", "Item 3"};
    comboBox.addItems(items);

    window.show();

    return app.exec();
}
