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.
The MainWindow class declares a QMainWindow based user interface, using the Ui::MainWindow class generated by Qt Designer. A number of slots are implemented to handle events from the various user interface elements, including the WebBrowser object, which is a QAxWidget hosting the Microsoft Web Browser control.
The constructor initializes the user interface, installs a progress bar on the status bar, and uses QAxBase::dynamicCall() to invoke the GoHome() method of Internet Explorer to navigate to the user's home page.
Different slots handle the signals emitted by the WebBrowser object.
Connections that don't require any coding, i.e. connecting the back action to the GoBack() slot, have already been made in Qt Designer.
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 examples/activeqt/webbrowser and run the resulting webbrowser.exe.
