Qt 调用本地浏览器打开URL

点击Qt某些控件，查找本地浏览器打开前端传递的URL。

方法一：直接写死本地浏览器地址

 QString programAdress = "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe"
 QString m_strWebUrl = "http://www.baidu.com";
 QStringList arguments;
 arguments << "--chrome-frame" << m_strWebUrl;
 QProcess *chromeProcess = new QProcess();
 chromeProcess ->start(programAdress ,arguments );

方法二：本地库

 SHELLEXECUTEINFOA info;
 memset(&info, , sizeof(info));
 std::string url = "http://www.baidu.com";
 std::string text = url;

 info.cbSize = sizeof(SHELLEXECUTEINFOA);
 info.hwnd = NULL;
 info.lpVerb = "open";
 info.lpFile = "chrome.exe";
 info.lpParameters = text.c_str();
 info.nShow = SW_SHOWMAXIMIZED;

 bool ret = ShellExecuteExA(&info);

SHELLEXECUTEINFOA、ShellExecuteExA 源自：C:\Program Files (x86)\Windows Kits\8.1\Include\um\shellapi.h

SW_SHOWMAXIMIZED  显示方式  源自： C:\Program Files (x86)\Windows Kits\8.1\Include\um\WinUser.h

方法三：注册表

 #ifdef  WIN32
     QSettings a("HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\App Paths\\Chrome.exe",QSettings::NativeFormat);
     QSettings strPath = a.value("Default").toString();
     QString strUrl = QString("\"%1\" %2").arg(strPath).srg(strUrl);
     WinExec(strUrl.toStdString().c_str(),SW_SHOWNORMAL);
 #else
     QDesktopServices::openUrl(QUrl(strUrl));
 #endif
