HTTP and + proxy authentication can be used for accessing web pages. + + \include examples-run.qdocinc + + \section1 Class Hierarchy + + We start with sketching a diagram of the classes that we are going to + implement: + + \image simplebrowser-model.png + + \list + \li \c{Browser} is a singleton class managing the application windows. + \li \c{BrowserWindow} is a \l QMainWindow showing the menu, a navigation + bar, \c {TabWidget}, and a status bar. + \li \c{TabWidget} is a \l QTabWidget and contains one or multiple + browser tabs. + \li \c{WebView} is a \l QWebEngineView, provides a view for \c{WebPage}, + and is added as a tab in \c{TabWidget}. + \li \c{WebPage} is a \l QWebEnginePage that represents website content. + \endlist + + \section1 Creating the Browser Main Window + + This example supports multiple main windows that are owned by a + \c Browser singleton object. This class could also be used for further + functionality, such as downloading files, bookmarks, and history managers. + + In \c main.cpp, we create the first \c BrowserWindow instance and add it + to the \c Browser object.
