最近開發中遇到QWebEngine嵌入網頁，控制語音的開關雙擊無效的問題。找到如下的解決方案：

#include <QApplication> #include <QUrl> #include <QWebEngineView>class WebEnginePage: public QWebEnginePage{Q_OBJECT public:WebEnginePage(QObject *parent = Q_NULLPTR):QWebEnginePage(parent){connect(this, &WebEnginePage::featurePermissionRequested, this, &WebEnginePage::onFeaturePermissionRequested);} private Q_SLOTS:void onFeaturePermissionRequested(const QUrl &securityOrigin, QWebEnginePage::Feature feature){if(feature == QWebEnginePage::MediaAudioCapture|| feature == QWebEnginePage::MediaVideoCapture|| feature == QWebEnginePage::MediaAudioVideoCapture)setFeaturePermission(securityOrigin, feature, QWebEnginePage::PermissionGrantedByUser);elsesetFeaturePermission(securityOrigin, feature, QWebEnginePage::PermissionDeniedByUser);} };int main(int argc, char *argv[]) {QApplication app(argc, argv); 關鍵代碼如下：QWebEngineView view;view.setPage(new WebEnginePage);view.setUrl(QUrl("https://baidu.com"));view.show();return app.exec(); }

實測有效~~
