在qt中如何加入歌词，写一段详细的代码

当然，我可以为您提供一个更详细的代码示例来在 Qt 中加入歌词。以下是一个使用 QTextEdit 控件和定时器来实现的简单歌词显示窗口的示例代码：

#include <QtWidgets>

class LyricsWindow : public QWidget
{
    Q_OBJECT

public:
    LyricsWindow(QWidget *parent = nullptr)
        : QWidget(parent)
    {
        lyricsTextEdit = new QTextEdit(this);
        lyricsTextEdit->setReadOnly(true);
        lyricsTextEdit->setAlignment(Qt::AlignCenter);
        lyricsTextEdit->setFont(QFont("Arial", 20));
        lyricsTextEdit->setStyleSheet("background-color: transparent;");

        QTimer* timer = new QTimer(this);
        connect(timer, &QTimer::timeout, this, &LyricsWindow::showNextLyric);
        timer->start(3000); // 每隔3秒更新一次歌词

        QVBoxLayout* layout = new QVBoxLayout(this);
        layout->addWidget(lyricsTextEdit);
        setLayout(layout);

        loadLyricsFromFile("lyrics.txt"); // 从文件加载歌词
    }

private:
    QTextEdit* lyricsTextEdit;
    QStringList lyricsList;
    int currentLyricIndex = 0;

    void loadLyricsFromFile(const QString& filePath)
    {
        QFile file(filePath);
        if (file.open(QIODevice::ReadOnly | QIODevice::Text))
        {
            QTextStream stream(&file);
            while (!stream.atEnd())
            {
                QString line = stream.readLine().trimmed();
                if (!line.isEmpty())
                    lyricsList.append(line);
            }
            file.close();
        }
    }

    void showNextLyric()
    {
        if (currentLyricIndex < lyricsList.size())
        {
            lyricsTextEdit->setText(lyricsList[currentLyricIndex]);
            ++currentLyricIndex;
        }
        else
        {
            lyricsTextEdit->clear();
            currentLyricIndex = 0;
        }
    }
};

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

    LyricsWindow window;
    window.setGeometry(100, 100, 400, 200);
    window.show();

    return app.exec();
}

#include "main.moc"

上面的代码创建了一个窗口，加载了一个名为 "lyrics.txt" 的歌词文件。然后，定时器每隔3秒钟显示下一句歌词。您可以根据需要对字体、颜色和布局进行自定义。请确保将歌词文件放置在正确的位置，并根据实际情况进行修改。
