QT 多级嵌套结构体,遍历成员--半自动。＜模板+宏定义＞QTreeWidget树结构显示

Qt的QTreeWidget来显示嵌套结构体的成员，并以树形结构展示。

#include <QApplication>
#include <QTreeWidget>
#include <QTreeWidgetItem>
#include <QString>
#include <cstdint>

// 假设这些是你的结构体定义
struct BaseMeterParam_Type {
    int param1;
    float param2;
};

struct NetParam_Type {
    QString ipAddress;
    int port;
};

struct TimingUploadParam_Type {
    int interval;
    bool enabled;
};

struct LadderParam_Type {
    int stepCount;
    float stepValue;
};

struct DeviceParam_Type {
    BaseMeterParam_Type mt_BaseMeter;
    NetParam_Type mt_Net;
    TimingUploadParam_Type mt_TimingUpload;
    LadderParam_Type mt_RunLadder;
    uint16_t m_None;
    uint16_t m_Crc16;
};

// 模板函数，用于将结构体成员添加到树中
template<typename T>
void addMemberToTree(QTreeWidgetItem* parent, const QString& name, const T& value) {
    QTreeWidgetItem* item = new QTreeWidgetItem(parent);
    item->setText(0, name);
    item->setText(1, QString::number(value));
}

// 特化模板函数，用于处理QString
template<>

    QTreeWidgetItem* item = new QTreeWidgetItem(parent);
    item->setText(0, name);

// 宏定义，用于遍历结构体成员
#define ADD_MEMBER_TO_TREE(parent, member) addMemberToTree(parent, #member, deviceParam.member)

// 定义一个函数来遍历DeviceParam_Type的成员并添加到树中
void traverseDeviceParamToTree(QTreeWidget* tree, const DeviceParam_Type& deviceParam) {

    ADD_MEMBER_TO_TREE(mt_TimingUploadItem, mt_TimingUpload.interval);
    ADD_MEMBER_TO_TREE(mt_TimingUploadItem, mt_TimingUpload.enabled);

    // 添加mt_RunLadder成员

    mt_RunLadderItem->setText(0, "mt_RunLadder");
    ADD_MEMBER_TO_TREE(mt_RunLadderItem, mt_RunLadder.stepCount);
