文档使用QaxWidget在QT内完成信号

Question

我正在使用/示例/activeqt/webbrowser中的qt内置示例，我正在尝试使用documentComplete信号。我的目的是在DocumentComplete之后使用QaxWidget内部的嵌入式Internet Explorer和弹出消息（网站上的Contetnt）。NavigateComplete信号对我来说还不够好...

可以在此处看到代码：QT Web浏览器示例

class MainWindow : public QMainWindow, public Ui::MainWindow
{
    Q_OBJECT
public:
    MainWindow();
public slots:
    void on_WebBrowser_TitleChange(const QString &title);
    void on_WebBrowser_ProgressChange(int a, int b);
    void on_WebBrowser_CommandStateChange(int cmd, bool on);
    void on_WebBrowser_BeforeNavigate();
    void on_WebBrowser_NavigateComplete(const QString &address);
    void on_WebBrowser_DocumentComplete(IDispatch*,QVariant&)
    void on_actionGo_triggered();
    void on_actionNewWindow_triggered();
    void on_actionAddBookmark_triggered();
    void on_actionAbout_triggered();
    void on_actionAboutQt_triggered();
    void on_actionFileClose_triggered();
private:
    QProgressBar *m_progressBar;
 
};
MainWindow::MainWindow()
{
    setupUi(this);
  
    connect(m_addressEdit, SIGNAL(returnPressed()), actionGo, SLOT(trigger()));
    connect(actionBack, SIGNAL(triggered()), WebBrowser, SLOT(GoBack()));
    connect(actionForward, SIGNAL(triggered()), WebBrowser, SLOT(GoForward()));
    connect(actionStop, SIGNAL(triggered()), WebBrowser, SLOT(Stop()));
    connect(actionRefresh, SIGNAL(triggered()), WebBrowser, SLOT(Refresh()));
    connect(actionHome, SIGNAL(triggered()), WebBrowser, SLOT(GoHome()));
    connect(actionSearch, SIGNAL(triggered()), WebBrowser, SLOT(GoSearch()));
    connect(WebBrowser,SIGNAL(DocumentComplete(IDispatch*,QVariant&), this, SLOT(on_WebBrowser_DocumentComplete(IDispatch*,QVariant&)))
}
void MainWindow::on_WebBrowser_DocumentComplete(IDispatch*,QVariant&)
{
    QMessangeBox x;
    x.setText("pop-up");
    x.exec();
}

dubbuger说：没有这样的插槽mainwindow :: on_webbrowser_documentComplete（idispatch*，qvaria‌nt＆amp;）

只要解决方法不仅需要评论：

MyWidgetUsesActiveX::MyWidgetUsesActiveX()
{
    ///
    connect(m_pActiveX, SIGNAL(signal(const QString&, int, void*)),
        this, SLOT(activexEventHandler(const QString&, int, void*)));
}
void MyWidgetUsesActiveX::activexEventHandler(
                             const QString &name, int argc, void *argv)
{
    VARIANTARG *params = (VARIANTARG*)argv;
    // See what events fired
    qDebug() << "Event:" << name << "argc:" << argc;
    // some concrete example
    if (name == "OnRemoteWindowDisplayed")
    {
        // Extract parameters
        _variant_t varValue = params[argc-1];
        bool bDisplayed = (bool)varValue;
        // hwnd
        varValue = params[argc-2];
        int iResult = (int)varValue;
        varValue = params[argc-3];
        int windowAttribute = (int) varValue;
        // CALL that stubborn slot we cannot have called otherwise
        onRemoteWindowDisplayed(bDisplayed, iResult, windowAttribute);
    }
    else if (name == "OnSomethingElse")
    {
        // extract concrete parameters and call the handler from here
        // onSomethingElse(param1, param2, param3);
    }
    else
    {
        // Log it?
    }
}

i通过再生.moc文件解决了问题。在构建配置下，Qmake的文件夹位置是错误的。通过将其纠正到项目位置解决了我的问题。现在已识别该插槽。谢谢大家的帮助。
