QWebEngineView can not react to keyPressEvent ?

anyetiangong

I create a class which implements from QWebEngineView, it override the keyPressEvent function. But this function has never called.

Then I run some tests with event function. It works fine with QWidget. Debug info outputed from QWidget event when I pressed a key in the widget:

widget event , event type : 51
widget event , event type : 207 (InputMethodQuery)
widget event , event type : 51
widget event , event type : 51
widget event , event type : 6 (KeyPress)
keypress event : QKeyEvent(KeyPress, key=0x46, text="f")
widget event , event type : 7 (KeyRelease)

But there was only 51 in QWebEngineView, which wasn't mentioned in QEvent class:

web engine event , event type : 51
web engine event , event type : 51
web engine event , event type : 51

Here is my code :

class WebEnigne : public QWebEngineView
{
    Q_OBJECT
public:
    explicit WebEnigne(QWidget* parent = 0);

protected:
    virtual void keyPressEvent(QKeyEvent *event) Q_DECL_OVERRIDE;
    virtual bool event(QEvent* event) Q_DECL_OVERRIDE;

};


WebEnigne::WebEnigne(QWidget* parent)
    : QWebEngineView(parent)
{}

void WebEnigne::keyPressEvent(QKeyEvent* event)
{
    // keypressevent has never been called
    qDebug() << "keypress event : " << event->key();

    QWebEngineView::keyPressEvent(event);
}

bool WebEnigne::event(QEvent* event)
{
    qDebug() << "web engine event , event type : " << event->type();
    switch(event->type())
    {
    case QEvent::KeyPress:
        qDebug() << "web engine key press : ";
        break;
    }
    return QWebEngineView::event(event);
}

This posts looks very old, but still not answered. I think keypress event is not working properly in QtWebEngineView. Did you tried the evenfilter mechanism. I tried and it is working well in my Qt WebEngine project. https://wiki.qt.io/How_to_catch_enter_key
