| 30 | \title Web Browser Example (ActiveQt)
|
|---|
| 31 |
|
|---|
| 32 | The Web Browser example uses the Microsoft Web Browser
|
|---|
| 33 | ActiveX control to implement a fully functional Web Browser
|
|---|
| 34 | application. The user interface has been developed using the Qt
|
|---|
| 35 | Designer integration of the QAxWidget class.
|
|---|
| 36 |
|
|---|
| 37 | The code demonstrates how the Qt application can communicate
|
|---|
| 38 | with the embedded ActiveX controls using signals, slots and the
|
|---|
| 39 | dynamicCall() function.
|
|---|
| 40 |
|
|---|
| 41 | \snippet examples/activeqt/webbrowser/main.cpp 0
|
|---|
| 42 |
|
|---|
| 43 | The \c MainWindow class declares a \c QMainWindow based user interface,
|
|---|
| 44 | using the \c Ui::MainWindow class generated by Qt Designer. A number
|
|---|
| 45 | of slots are implemented to handle events from the various user
|
|---|
| 46 | interface elements, including the \c WebBrowser object, which is a
|
|---|
| 47 | QAxWidget hosting the Microsoft Web Browser control.
|
|---|
| 48 |
|
|---|
| 49 | \snippet examples/activeqt/webbrowser/main.cpp 1
|
|---|
| 50 |
|
|---|
| 51 | The constructor initializes the user interface, installs a
|
|---|
| 52 | progress bar on the status bar, and uses QAxBase::dynamicCall()
|
|---|
| 53 | to invoke the \c GoHome() method of Internet Explorer to
|
|---|
| 54 | navigate to the user's home page.
|
|---|
| 55 |
|
|---|
| 56 | \snippet examples/activeqt/webbrowser/main.cpp 2
|
|---|
| 57 | Different slots handle the signals emitted by the WebBrowser object.
|
|---|
| 58 |
|
|---|
| 59 | Connections that don't require any coding, i.e. connecting the \c back
|
|---|
| 60 | action to the \c GoBack() slot, have already been made in Qt Designer.
|
|---|
| 61 |
|
|---|
| 62 | \snippet examples/activeqt/webbrowser/main.cpp 3
|
|---|
| 63 | \snippet examples/activeqt/webbrowser/main.cpp 4
|
|---|
| 64 |
|
|---|
| 65 | The rest of the implementation is not related to ActiveQt - the actions
|
|---|
| 66 | are handled by different slots, and the entry point function starts the
|
|---|
| 67 | application using standard Qt APIs.
|
|---|
| 68 |
|
|---|
| 69 | To build the example you must first build the QAxContainer
|
|---|
| 70 | library. Then run your make tool in \c
|
|---|
| 71 | examples/activeqt/webbrowser and run the resulting \c
|
|---|
| 72 | webbrowser.exe.
