模态框和非模态框

https://blog.csdn.net/mpp_king/article/details/79902755

模态弹框和非模态弹框最大的区别就是是否强制用户交互。模态弹框会打断用户的当前操作流程，用户不在弹框上操作的话，其余功能都使用不了。从这方面，我们可以看出来模态弹框的优缺点都十分的明显：优点是可以很好的获取的用户的视觉焦点，缺点是打断了用户的当前操作流程。模态弹框属于一种重量性反馈，一般用于用户进行重要的操作。

C++读取配置文件的几种方法

C++读取配置文件的几种方法_零点零一的博客-CSDN博客_c++读取配置文件

#include <iostream>
#include <fstream>
#include <map>
#include <string>

class ConfigFile {
public:
    ConfigFile(const std::string &filename) : m_filename(filename) {}
    bool load();
    bool save();
    std::string getValue(const std::string &key) const;
    void setValue(const std::string &key, const std::string &value);

private:
    std::string m_filename;
    std::map<std::string, std::string> m_values;
};

bool ConfigFile::load() {
    std::ifstream file(m_filename);
    if (!file.is_open()) {
        return false;
    }
    std::string line;
    while (std::getline(file, line)) {
        size_t pos = line.find('=');
        if (pos != std::string::npos) {
            std::string key = line.substr(0, pos);
            std::string value = line.substr(pos + 1);
            m_values[key] = value;
        }
    }
    file.close();
    return true;
}

bool ConfigFile::save() {
    std::ofstream file(m_filename);
    if (!file.is_open()) {
        return false;
    }
    for (const auto &pair : m_values) {
        file << pair.first << "=" << pair.second << std::endl;
    }
    file.close();
    return true;
}

std::string ConfigFile::getValue(const std::string &key) const {
    auto it = m_values.find(key);
    if (it != m_values.end()) {
        return it->second;
    }
    return "";
}

void ConfigFile::setValue(const std::string &key, const std::string &value) {
    m_values[key] = value;
}

使用

int main() {
    ConfigFile config("config.ini");
    if (!config.load()) {
        std::cout << "Failed to load config file" << std::endl;
        return 1;
    }
    std::string value = config.getValue("key");
    std::cout << "Value of key: " << value << std::endl;
    config.setValue("key", "new value");
    if (!config.save()) {
        std::cout << "Failed to save config file" << std::endl;
        return 1;
    }
    return 0;
}
