\example activeqt/webbrowser
\title Web Browser Example (ActiveQt)
The Web Browser example uses the Microsoft Web Browser
ActiveX control to implement a fully functional Web Browser
application. The user interface has been developed using the Qt
Designer integration of the QAxWidget class.
The code demonstrates how the Qt application can communicate
with the embedded ActiveX controls using signals, slots and the
dynamicCall() function.
\snippet examples/activeqt/webbrowser/main.cpp 0
The \c MainWindow class declares a \c QMainWindow based user interface,
using the \c Ui::MainWindow class generated by Qt Designer. A number
of slots are implemented to handle events from the various user
interface elements, including the \c WebBrowser object, which is a
QAxWidget hosting the Microsoft Web Browser control.
\snippet examples/activeqt/webbrowser/main.cpp 1
The constructor initializes the user interface, installs a
progress bar on the status bar, and uses QAxBase::dynamicCall()
to invoke the \c GoHome() method of Internet Explorer to
navigate to the user's home page.
\snippet examples/activeqt/webbrowser/main.cpp 2
Different slots handle the signals emitted by the WebBrowser object.
Connections that don't require any coding, i.e. connecting the \c back
action to the \c GoBack() slot, have already been made in Qt Designer.
\snippet examples/activeqt/webbrowser/main.cpp 3
\snippet examples/activeqt/webbrowser/main.cpp 4
The rest of the implementation is not related to ActiveQt - the actions
are handled by different slots, and the entry point function starts the
application using standard Qt APIs.
To build the example you must first build the QAxContainer
library. Then run your make tool in \c
examples/activeqt/webbrowser and run the resulting \c
webbrowser.exe.
