QTabWidget中添加QWebEngineView控件后QTabWidget无法切换怎么办

可能是因为QWebEngineView控件会捕获鼠标事件，导致QTabWidget无法响应切换事件。可以尝试在QWebEngineView控件中重写mousePressEvent和mouseReleaseEvent方法，将事件传递给父控件QTabWidget。代码示例如下：

class MyWebEngineView : public QWebEngineView
{
public:
    MyWebEngineView(QWidget *parent = nullptr) : QWebEngineView(parent) {}

protected:
    void mousePressEvent(QMouseEvent *event) override
    {
        QWebEngineView::mousePressEvent(event);
        if (parentWidget())
            parentWidget()->mousePressEvent(event);
    }

    void mouseReleaseEvent(QMouseEvent *event) override
    {
        QWebEngineView::mouseReleaseEvent(event);
        if (parentWidget())
            parentWidget()->mouseReleaseEvent(event);
    }
};

然后在添加QWebEngineView控件时，使用这个自定义的MyWebEngineView控件代替原来的QWebEngineView控件即可。

QTabWidget *tabWidget = new QTabWidget(this);
MyWebEngineView *webView = new MyWebEngineView(tabWidget);
tabWidget->addTab(webView, tr("Tab"));
