Action path: VS2010 ==> File ==> New ==> Project ==> "Qt5 Projects" ==> "Qt Application"

Attention matters

Select the "WebKit" and "WebKit Widgets" options in "Project Settings":

2. Add header File

#include <QtGui> #include <QtWebKit> #include <QWebView>

3. Content Analysis

3.1, parsing the http form of the URL

Using the Qwebview SetUrl method, the example is as follows:

Qwebview view; View.show (); View.seturl (Qurl ("Http://www.cnblogs.com/mikezhang"));

3.2. Resolve Local Files

Using the Qwebview SetUrl method, the example is as follows:

Qwebview view; View.show (); View.seturl (Qurl ("file:///E:/tmp/1.html"));

3.3. Parse HTML string

Using the Qwebview sethtml method, the example is as follows:

Qapplication app (argc, argv); Qwebview view; View.show (); Std::ifstream fin ("e:/tmp/1.html"); Std::stringstream buffer; Buffer << fin.rdbuf (); Fin.close (); View.sethtml (Buffer.str (). C_STR ());

The complete code is as follows:

#include <QtGui> #include <QtWebKit> #include <QWebView> #include <fstream> #include < string> #include <sstream> int main (int argc, char *argv[]) {   qapplication app (argc, argv);   &N Bsp Qwebview view;    view.show ();    //method 1:a remote URL    //view.seturl (Qurl ("Http://www.cnblogs.com/mikezhang"));    //method 2:a The local URL    //view.seturl (Qurl ("file:///E:/tmp/1.html"));      //method 3:set HTML content      std::ifstream fin ("e:/tmp/1.html");      std::stringstream buffer;      buffer << fin.rdbuf ();      fin.close ();    view.sethtml (Buffer.str (). C_STR ());    return app.exec (); }
