Description

An instance of the QWebHistory class can be used to navigate through the history of web pages, displayed using QWebView.

Solution

The following code snippet shows how to use the QWebHistory class to move back or forward through web history items.

 #include <QWebView>
 #include <QWebHistory>
 
  WebMainView::WebMainView( QWidget *parent )
      : QMainWindow( parent )
  {
    web = new QWebView();
    QVBoxLayout *layout = new QVBoxLayout();
    web->setLayout( layout );  
    setCentralWidget( web );
 
    // Retrieve and store a pointer to QWebHistory
    m_wHistory = web->history();
 
    web->load( QUrl( "http://www.ovi.mobi" ) );
  }
 
 
  // (slot): move back to the last history item 
  void WebMainView::Back()
  {
    if ( m_wHistory->canGoBack() ) {
      m_wHistory->back();
    }
  }
 
 
  // (slot): move forward by one history item
  void WebMainView::Forward()
  {
    if ( m_wHistory->canGoForward() ) {
      m_wHistory->forward();
    }
  }
