QtWebKit模块实现了HTML到DOM的解析,封装了Get等方法,直接使用就行了例:用代码实现在百度首页中输入关键字并提交,然后显示百度返回的搜索结果:
44.if(fileList.count() < 1)return;
45.
46. manager2 =new QNetworkAccessManager;
47.// QString fileName = "tootzoe.jpg";
48.QString newPathName ="newtootzoe.jpg";
49.
50.// foreach(QString fileName, fileList){
51.QString fileName = fileList.at(0);
52.file=new QFile(fileName);
53.if(!file->open(QFile::ReadOnly)){ qDebug() << "Error
opening file....";return ;}
54.
