link error with static webkit 4.8.1

Hi all,

I’m stuck with a basic link error.

I’m using Visual 2008 and the Qt pluging on Windows 7 ×64 and Qt 4.8.1

I have a small class who inherits from QWebPage and I cannot link it with QWebkit.

my class :

class MyQWebPage: public QWebPage {
Q_OBJECT ;
private:
ResourceObject & resource;
public:
MyQWebPage(ResourceObject & res);
virtual void javaScriptAlert(QWebFrame * frame, const QString & msg);
virtual bool javaScriptConfirm(QWebFrame * frame, const QString & msg);
virtual bool javaScriptPrompt(QWebFrame * frame, const QString & msg, const QString & defaultValue, QString * result);
virtual void javaScriptConsoleMessage(const QString & message, int lineNumber, const QString & sourceID);
public slots:
bool shouldInterruptJavaScript();
};

first error :
1>mywebclass.obj : error LNK2001: unresolved external symbol “public: static struct QMetaObject const QWebPage::staticMetaObject” (?staticMetaObject@QWebPage@@2UQMetaObject@@B)

And I have 8 of them like this one.

In the Qt project settings, QwebKit is included, on the project setting the lib file QtWebKitd4.lib is a dependencies.

In the file there are other class like

class MyNetworkAccessManager: public QNetworkAccessManager {
Q_OBJECT
private:
...
public:
...
signals:
...
};

but those one does not produce link error.

Can someone help me ?

Thanks.

welcome to devnet

Did you create static Qt libs?
AFAIK that is not possible with webkit.

thanks for your response.

Nope, I’m using the web kit as provided by qt, using the lib file and header files and at last the dlls.

It is not supported to use webkit in a static build of Qt. It was mentioned in some documentation, but I don’t remember where exactly.

If so, how can we use web feature, i mean something like QWebPage or QWebView, in static build of Qt?

Ohh, it’s really a bad news to me.
I have to i have to use web feature in a static build of Qt.
I can’t believe that there was no web control before webkit was intergrated into Qt.
Anyway, thanks for your reply, Volker.

While not a full featured web browser, QTextBrowser might support a suitable subset of HTML for your use case.
