創建全局變量.h文件
globalvariable.h
1 #ifndef GLOBALVARIABLE_H 2 #define GLOBALVARIABLE_H
3 #include <QImage>
4
5 //全局變量
6 class GlobalVariable 7 { 8 public: 9 //圖像變量
10 static QImage GV_QImage; 11 };
main.cpp
1 #include "XXXXX.h"
2 #include <QApplication>
3
4 int main(int argc, char *argv[]) 5 { 6 QApplication a(argc, argv); 7 JaiCamera w; 8 w.show(); 9
10 return a.exec(); 11 } 12
13 //全局變量初始化
14 QImage GlobalVariable::GV_QImage;
需要用到的.cpp程序里
GlobalVariable::GV_QImage = XXXXXX;
