CubieAIO-A20 用QT做简单的wifi扫描界面

Reachy

硬件:CubieAIO-A20 开发板
固件:CubieAIO-A20固件地址

这个只是一个简单的demo,界面没有优化,比较粗糙,简单,但是效果是可以的,实现扫描周围的
wifi热点,做了刷新的按钮,想做到和安卓手机用wifi上网的效果一样.不多说了,直接上代码,

这是main.ccp程序

1. #include "widget.h"
   
2. #include <QApplication>
   
3. //#include <QtQuick/QtQuick>
   
4. 
   
5. int main(int argc, char *argv[])
   
6. {
   
7.     qputenv("QT_IM_MODULE",QByteArray("qtvirtualkeyboard"));
   
8.     QApplication a(argc, argv);
   
9.     Widget w;
   
10.     w.show();
    
11. 
    
12.     return a.exec();
    
13. }
