Qt编写一个注册码工具

以下是一个简单的Qt界面，用于生成注册码并验证输入的注册码是否有效。请注意，此代码仅供参考，您需要根据您的具体需求进行修改和优化。

#include <QtWidgets/QApplication>
#include <QtWidgets/QMainWindow>
#include <QtWidgets/QLabel>
#include <QtWidgets/QLineEdit>
#include <QtWidgets/QPushButton>
#include <QRegExp>
#include <QClipboard>
#include <QMessageBox>

class RegistrationTool : public QMainWindow
{
    Q_OBJECT

public:
    RegistrationTool(QWidget *parent = nullptr)
        : QMainWindow(parent)
    {
        // 窗口标题
        setWindowTitle(tr("Registration Tool"));

        // 注册码标签
        QLabel* registrationCodeLabel = new QLabel(this);
        registrationCodeLabel->setText(tr("Registration Code:"));
        registrationCodeLabel->setGeometry(20, 20, 120, 30);

        // 注册码输入框
        QLineEdit* registrationCodeEdit = new QLineEdit(this);
        registrationCodeEdit->setGeometry(140, 20, 200, 30);

        // 生成注册码按钮
        QPushButton* generateButton = new QPushButton(this);
        generateButton->setText(tr("Generate"));
        generateButton->setGeometry(360, 20, 80, 30);
        connect(generateButton, &QPushButton::clicked, [=]() {
            QString registrationCode = generateRegistrationCode();
            registrationCodeEdit->setText(registrationCode);
        });

        // 验证注册码按钮
        QPushButton* verifyButton = new QPushButton(this);
        verifyButton->setText(tr("Verify"));
        verifyButton->setGeometry(20, 70, 80, 30);
        connect(verifyButton, &QPushButton::clicked, [=]() {
            QString registrationCode = registrationCodeEdit->text();
            if (verifyRegistrationCode(registrationCode)) {
                QMessageBox::information(this, tr("Success"), tr("Registration code is valid!"));
            } else {
                QMessageBox::warning(this, tr("Error"), tr("Registration code is invalid!"));
            }
        });

        // 复制注册码按钮
        QPushButton* copyButton = new QPushButton(this);
        copyButton->setText(tr("Copy"));
        copyButton->setGeometry(140, 70, 80, 30);
        connect(copyButton, &QPushButton::clicked, [=]() {
            QString registrationCode = registrationCodeEdit->text();
            QClipboard* clipboard = QApplication::clipboard();
            clipboard->setText(registrationCode);
            QMessageBox::information(this, tr("Success"), tr("Registration code copied to clipboard!"));
        });
    }

private:
    QString generateRegistrationCode()
    {
        // TODO: 根据具体需求生成注册码
        return "ABCDEFGH";
    }

    bool verifyRegistrationCode(QString registrationCode)
    {
        // TODO: 根据具体需求验证注册码是否有效
        QRegExp rx("[A-Z]{8}");
        return rx.exactMatch(registrationCode);
    }
};

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    RegistrationTool w;
    w.show();
    return a.exec();
}

您需要根据具体需求实现 `generateRegistrationCode()` 和 `verifyRegistrationCode()` 函数，这里只是提供了一个简单的正则表达式验证。在实际开发中，您需要更加严谨的验证方法来保证生成和验证的注册码的安全性和有效性。
