44 \title Web Browser Example (ActiveQt) |
|
45 |
|
46 The Web Browser example uses the Microsoft Web Browser |
|
47 ActiveX control to implement a fully functional Web Browser |
|
48 application. The user interface has been developed using the Qt |
|
49 Designer integration of the QAxWidget class. |
|
50 |
|
51 The code demonstrates how the Qt application can communicate |
|
52 with the embedded ActiveX controls using signals, slots and the |
|
53 dynamicCall() function. |
|
54 |
|
55 \snippet examples/activeqt/webbrowser/main.cpp 0 |
|
56 |
|
57 The \c MainWindow class declares a \c QMainWindow based user interface, |
|
58 using the \c Ui::MainWindow class generated by Qt Designer. A number |
|
59 of slots are implemented to handle events from the various user |
|
60 interface elements, including the \c WebBrowser object, which is a |
|
61 QAxWidget hosting the Microsoft Web Browser control. |
|
62 |
|
63 \snippet examples/activeqt/webbrowser/main.cpp 1 |
|
64 |
|
65 The constructor initializes the user interface, installs a |
|
66 progress bar on the status bar, and uses QAxBase::dynamicCall() |
|
67 to invoke the \c GoHome() method of Internet Explorer to |
|
68 navigate to the user's home page. |
|
69 |
|
70 \snippet examples/activeqt/webbrowser/main.cpp 2 |
|
71 Different slots handle the signals emitted by the WebBrowser object. |
|
72 |
|
73 Connections that don't require any coding, i.e. connecting the \c back |
|
74 action to the \c GoBack() slot, have already been made in Qt Designer. |
|
75 |
|
76 \snippet examples/activeqt/webbrowser/main.cpp 3 |
|
77 \snippet examples/activeqt/webbrowser/main.cpp 4 |
|
78 |
|
79 The rest of the implementation is not related to ActiveQt - the actions |
|
80 are handled by different slots, and the entry point function starts the |
|
81 application using standard Qt APIs. |
|
82 |
|
83 To build the example you must first build the QAxContainer |
|
84 library. Then run your make tool in \c |
|
85 examples/activeqt/webbrowser and run the resulting \c |
|
86 webbrowser.exe. |
