如何创建具有动态文本输入数量的Qt对话框？

// dialog.h
#ifndef DIALOG_H
#define DIALOG_H

#include <QDialog>
#include <QLineEdit>

class Dialog : public QDialog
{
    Q_OBJECT

public:
    Dialog(QWidget *parent = nullptr);
    ~Dialog();

private slots:
    void onInputCountChanged();

private:
    int inputCount;
    QList<QLineEdit*> inputFields;
};

#endif // DIALOG_H

// dialog.cpp
#include "dialog.h"
#include <QVBoxLayout>
#include <QPushButton>

Dialog::Dialog(QWidget *parent)
    : QDialog(parent), inputCount(3)
{
    QVBoxLayout *layout = new QVBoxLayout(this);

    // 创建默认数量的文本输入控件
    for (int i = 0; i < inputCount; ++i) {
        QLineEdit *lineEdit = new QLineEdit(this);
        layout->addWidget(lineEdit);
        inputFields.append(lineEdit);
    }

    // 创建按钮用于改变输入数量
    QPushButton *button = new QPushButton("Change Input Count", this);
    layout->addWidget(button);

    connect(button, &QPushButton::clicked, this, &Dialog::onInputCountChanged);
}

Dialog::~Dialog()
{
}

void Dialog::onInputCountChanged()
{
    // 删除旧的文本输入控件
    for (QLineEdit *lineEdit : inputFields) {
        layout()->removeWidget(lineEdit);
        delete lineEdit;
    }
    inputFields.clear();

    // 获取新的输入数量
    bool ok;
    int newInputCount = QInputDialog::getInt(this, "Input Count", "Enter new input count:", inputCount, 1, 10, 1, &ok);
    if (ok) {
        inputCount = newInputCount;

        // 创建新的文本输入控件
        for (int i = 0; i < inputCount; ++i) {
            QLineEdit *lineEdit = new QLineEdit(this);
            layout()->addWidget(lineEdit);
            inputFields.append(lineEdit);
        }
    }
}
