可以在此处查看代码: qt Web浏览器示例

the code can be seen here : qt Web browser Example

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&)

the dubbuger says: No such slot MainWindow::on_WebBrowser_DocumentComplete(IDispatch*,QVaria‌​nt&)

推荐答案

我通过重新生成.moc文件解决了该问题.在构建配置下，qmake的文件夹位置错误.通过将其更正为项目位置可以解决我的问题.现在可以识别该插槽.谢谢大家的帮助.

i solved the issue by regenerating the .moc file. under build configuration the folder location of qmake was wrong. by correcting it to project location fixed my problem. the slot is now recognized. thank all for you help.
