I wrote to chromium developers, so, here is the summary It is not a crash, it is a failed debug assertion It happens if: you use webview's chromium backend (recent versions, old versions don't have this assertion) some part of you code consumes COM and that code's thread is not explicitly initializing COM via CoInitialize or CoInitializeEx My code uses a library that was not properly initializing COM in its threads before calling CoCreateInstance. Calling CoInitialize should fix my issue, but I cannot prove it until I have access to that libraries source code. What is left to be done by qt/webview team is to fix the failed assertion on "Chrome_InProcGpuThread" which is not created by user.

@l2pd said in QWebEngineView problems with <select> fields: I'm having this problems on a Windows 10 x64 machine. I didn't tried it on linux. Sorry I forgot to mention that I have this problems with version 5.7.0 of Qt.

First a note that SwipeView and its base type Container have gained some new members in Qt Quick Controls 2.1 in the upcoming Qt 5.8. These will help with your tasks: SwipeView::interactive Container::incrementCurrentIndex() Container::decrementCurrentIndex() For the time being, you could add the following binding as a temporary workaround until you will be able to use the new public interactive property: Binding { property: "interactive" target: swipeView.contentItem value: swipeView.currentIndex !== indexOfWebEngineView }

The solution was simple, i was inattentive, but Web Engine Team helps me, thanks guys webView.onNavigationRequested: { if(request.navigationType === WebEngineView.BackForwardNavigation) { print("onNavigationRequested", request.url) request.action = WebEngineView.IgnoreRequest; } }

Hi, The first report as been put on hold waiting for more input and the second state that it's been fixed for the release candidate of Qt 5.6. So it should be fixed but for 5.6 not 5.5.1

@MicNielsen I guess it isn't possible :(

Here are the screenshots depicting the problem:

As I understand the problem with a proxy so no one decided? Thought the new firmware would fix the matter, but my proxy provider says that the problem is not on their side.

Disregard my previous post, cookies policy can be set in the QWebEngineProfile owned by the QWebEnginePage owned by the QWebEngineView, like this: ui->webView->page()->profile()->setPersistentCookiesPolicy(QWebEngineProfile::NoPersistentCookies); The page pointer remains the same for my purposes, at least.

I use this code to resolve my problem : Rectangle { width: (tabView.width)-30 Layout.preferredHeight: 400 z:1 WebEngineView { id: webview url: "http://google.com" anchors.fill: parent } }

Below is the one I tried. Now the link opens in a new window. But how do I make it open in a new tab. I checked the link which was provided in the previous code. But as beginner, it's too much for me to understand. #include "WebEnginePage.h" WebEnginePage::WebEnginePage(QObject *parent) : QWebEnginePage(parent) { connect(this,SIGNAL(urlChanged(QUrl)),this,SLOT(loadInTab(QUrl))); } WebEnginePage::~WebEnginePage() { } void WebEnginePage::loadInTab(QUrl url) { qDebug()<<"Page : "<<url; emit pageInNewTab(url); } #include "WebEngineView.h" WebEngineView::WebEngineView(QWidget *parent) : QWebEngineView(parent) { webPage = new WebEnginePage(this); setPage(webPage); setGeometry(0,35,dw.width(),dw.height()-35); // connect(page(),SIGNAL(urlChanged(QUrl)),this,SLOT(loadInNewTab(QUrl))); connect(page(),SIGNAL(pageInNewTab(QUrl)),this,SLOT(loadInNewTab(QUrl))); hide(); connect(this, SIGNAL(loadFinished(bool)), this, SLOT(onPageLoadFinished(bool))); } void WebEngineView::onPageLoadFinished(bool value) { qDebug()<<"WebEngineView::onPageLoadFinished"; show(); emit newTab(this); } WebEngineView::~WebEngineView() { } WebEngineView *WebEngineView::createWindow(QWebEnginePage::WebWindowType type) { Q_UNUSED(type); qDebug()<<"WebEngineView::createWindow"; WebEngineView *webView = new WebEngineView(); qDebug()<<"Index : "<<++index; WebEnginePage *newWeb = new WebEnginePage(webView); webView->setAttribute(Qt::WA_DeleteOnClose, true); webView->setPage(newWeb); //webView->show(); return webView; } void WebEngineView::loadInNewTab(QUrl url) { qDebug()<<"WebEngineView "<<index<<" : "<<url; // createWindow(QWebEnginePage::WebBrowserTab); } int WebEngineView::getIndex() const { return index; } void WebEngineView::setIndex(int value) { index = value; } #include "TabWindow.h" TabWindow::TabWindow(QWidget *parent) : QMainWindow(parent) { weView = new WebEngineView(this); weView->setGeometry(0,50,dw.width(),dw.height()); loadedUrl = QUrl("http://www.google.co.in"); //weView->load(QUrl(loadedUrl)); weView->webPage->load(loadedUrl); QWidget *centralWidget = new QWidget(this); tabWidget = new QTabWidget(centralWidget); tabWidget->setTabsClosable(true); //tabWidget->setElideMode(Qt::ElideRight); tabWidget->setFixedSize(dw.width(),dw.height()); loadedUrl = QUrl("http://www.google.co.in"); tabWidget->addTab(weView,loadedUrl.host()); setCentralWidget(centralWidget); currentIndex = 0; weView->setIndex(currentIndex); //weViewNew = new WebEngineView(this); connect(weView,SIGNAL(newTab(WebEngineView&)),this,SLOT(loadNewTab(WebEngineView7))); connect(tabWidget,SIGNAL(tabCloseRequested(int)),this,SLOT(closeTab(int))); } TabWindow::~TabWindow() { } void TabWindow::closeTab(int index) { tabWidget->removeTab(index); } void TabWindow::loadNewTab(WebEngineView *webView) { //webView->show(); tabWidget->addTab(webView,webView->webPage->url().host()); //tabWidget->setCurrentIndex(currentIndex); qDebug()<<"TabWindow::loadNewTab : "; }

Had the same issue. Even the topic is quite old I publish here my solution for anyone that might have this issue now. Note that I need to track the mouse, so I call setMouseTracking(true); in the constructor. class CustomWebEngineView: public QWebEngineView { public: explicit CustomWebEngineView(QWidget *parent = nullptr): QWebEngineView(parent) { QApplication::instance()->installEventFilter(this); setMouseTracking(true); } protected: bool eventFilter(QObject *object, QEvent *event) { if (object->parent() == this && event->type() == QEvent::MouseMove) { mouseMoveEvent(static_cast<QMouseEvent *>(event)); } return false; } };
