Description
Run the following code, and select rapidly text in the loaded web page.
#include <QtWebEngineWidgets> #include <QTimer> int main(int argc, char* argv[]) { QApplication app(argc, argv); QWebEngineView * contentWidget = new QWebEngineView(); contentWidget->load(QUrl("http://google.at")); contentWidget->show(); QObject::connect(contentWidget, &QWebEngineView::selectionChanged, [=] () { contentWidget->load(QUrl("http://google.at")); }); return app.exec(); }
This will eventually trigger the following DCHECK:
