[nicker player]

page()->settings()->setAttribute(QWebEngineSettings::ShowScrollBars,false);

I hided the scrollbar of the qwebengineview widget.
and I implemented the wheelEvent from the qwebengineview ,but u know it didnt work.

You migth show what you tried for the wheel event, and state what "t didnt work" means in practice. Depending you might look at the example at https://stackoverflow.com/a/69999649/489865 if it relates to your situation.

bool WidgetBrowser::eventFilter(QObject *obj, QEvent *e){
    if (obj == this)   
    {
        if (e->type() == QEvent::Wheel){
            QWheelEvent* event =(QWheelEvent*)e;
            int det = event->angleDelta().y();
            emit onSignalWheel(event);
        }
    }

    return QWidget::eventFilter(obj, e);
}

I put the code into the project.but the webengineview could not get the event from the webview.I dont know why.maybe it is related to the chrome framework?

The stackoverflow solution states and shows it is using focusProxy(), that was the whole point of it. So did you try that?

[SimonSchroeder]

If you want to use eventFilter you need to write a different class (just derived from QObject) that has the event filter and then call installEventFilter on your instance of WidgetBrowser with an object that has eventFilter implemented.

@SimonSchroeder
Have you/the OP looked at the stackoverflow link showing what to do? No other/different class, beyond the QWebEngineView-derived class, which I presume is the OP's WidgetBrowser. It shows exactly what they want you to try, see the use of focusProxy().....

Ive tried the code is object->parent(),it seemed works fine.
not the focusProxy() part.now I will tried the focusProxy() method .
I dont understand the focusProxy usage.

But don't you have to install the eventFilter somewhere in order to catch/filter the events? I think this is what @SimonSchroeder is talking about, which was not done in the StackOverflow example. IIRC the eventFilter won't receive all events just like that. Only if there's a "filtering object" set with webengine->installEventFilter(observer).
I'm not sure if the filter and the filtered object can be the same QObject. Never tried it.

Edit:
Never mind, the filter is installed on focusProxy() QObject...

Yes that was what I was drawing attention to for the OP. I don't know but the SO poster was saying mouse events (including wheel) go to focusProxy().
