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 TimingUploadParam_Type {int interval;bool enabled;
};struct LadderParam_Type {int stepCount;float stepValue;

}// 特化模板函数，用于处理QString
template<>
