C++Qt：0x03.基于QT5.12.12与MinGW7.2.0开发的文本编辑器_v2.0

本文最后更新于 121 天前，其中的信息可能已经有所发展或是发生改变。

前言

由于本次更新在使用某些功能时，原版本QT5.12.8与MSVC2017的编译器会出现一些报错，因此我将版本换至了QT5.12.12与MinGW7.2.0编译器

在本次更新中添加了

注册码功能，用户需要输入特定的注册码才能够使用此文本编辑器
查看历史记录功能，用户可在文件栏查看自己最近打开的文件，同时可以清除历史打开记录
Base64编码与解码，作为一名CTFer，我加上了这种很常见的编码格式，后续计划添加更多

安装包在这->Xm's Notepad_2_0

程序运行结果

打开程序时会出现以下界面

输入正确注册码之后

点击yes进入程序

进入程序之后点击文件就可以看见最近打开功能了，同时还加上了加解密功能，不过里面现在只有Base64

项目文件

相较于上一版的文件，我在其中新建了一个register文件，也就是login注册窗口，在其中实现了一些功能：

对注册码输入是否正确的判断
每个按钮控件所对应的输出结果
禁用关闭该窗口控件，无法通过右上角×号关闭该窗口
禁用任务管理器中关闭该窗口，无法使用任务管理器杀死该窗口进程

代码实现

mainwindow.h

正常的槽函数定义

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>

QT_BEGIN_NAMESPACE
namespace Ui { class MainWindow; }
QT_END_NAMESPACE

class MainWindow : public QMainWindow
{
    Q_OBJECT

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

private slots:
    void on_new_file_triggered();

    QString currentFile;

#endif // MAINWINDOW_H

register.h

定义了一个protected的nativeEvent方法，以便于后面使用

#ifndef REGISTER_H
#define REGISTER_H

#include <QDialog>
#include <windows.h>

namespace Ui {
class Register;
}

class Register : public QDialog
{
    Q_OBJECT

    ~Register();

private slots:

    void on_pushButton_clicked();

    void on_pushButton_2_clicked();

private:
    Ui::Register *ui;

protected:
    virtual bool nativeEvent(const QByteArray &eventType, void *message, long *result);
};

#endif // REGISTER_H
