Unsolved Moving from MSVC 2017 PRO to MSVC 2017 Community and QtWebEngine Error

I uninstalled MSVC Pro and Installed MSVC 2017 Community Edition and it seems none of my WebBrowser ( QtWebEngine) Apps work now.

Just to make sure, I installed all of QT and Microsoft Visual Studio 2017, restarted then re-installed with the same issue.

I am running QT 11.3 and trying to run the Quick Nano Browser from the Example Projects.

Do I need to reinstall the Pro version of MSVC, or is there an extra step I am missing?

I am trying to compile a 64 bit Version of MSVC 2017 Example Quick Nano Browser.

MSVC 2017

Unsolved 5.12.1 QWebEngine ClientSSL's Example

I saw in the patch change notes that Client SSL certificates were now support in 5.12.1. So I loaded the SimpleBrowser example.
When I ran it (built with MSVC2017 64bit) and then pointed it to a internal lan server that uses a Self Signed Client SSL authentication system. The example crashed.

So i put the example in debug, cleaned and rebuilt it. When i Ran it and pointed at the same server. The Application hangs up and gives this output, but does not kick over for a debug.

[12564:14860:0219/131011.251:WARNING:backend_impl.cc(1841)] Destroying invalid entry.

Then when i trying to stop the debuging. I can not. In fact i have to go into the task manager and kill cdb to get the program to terminate.

So at the moment it looks like the problem is located inside chromium, but can not say for sure. Since the example code doesn't want to run in debug mode when dealin with SSL's.

So at the moment i'm unsure where to go from here.

I use the camera in my application , I can close the camera fine in order to start a webrtc session, I can't restart the camera though, because I can't tell when the webengine has finished using the camera. Is there a way to terminate the webengine and be told when it is fully terminated.

I'm making a browser in Python with PyQt5. I want to enable Google Geo Location API. Basically I want to show popup when a site want to get user's location.

self.browser = QWebEngineView()
self.browser.allowGeolocationOnInsecureOrigins:True

If we can auto allow the browser for getting location permission that will be best.

Unsolved RPi3, WebView locks the mouse, while keyboard works fine

I'm trying to dinamically open and close a web view, using

LayoutVerticalMain->addWidget(&WebView);
WebView.load(QUrl(url));
WebView.show();

and

WebView.hide();

.
On the main.cpp I called

QtWebEngine::initialize();

before the

QMainWindow::show()

The view opens fine, but when I move the cursor over the WebView, the mouse "stops" at its border, without entering. If I use the keyboard's tab key to navigate the page, it works fine. Any clicking in any internal area seems to be ignored.

I'm using QT 5.12.0 on a raspberry Pi3, cross-compiled from a Ubuntu 16.04.

Did I miss any requirement, or skip some configuration?
Thanks.

Unsolved Accessibility and QtWebEngine

Have a desktop application built using QtWebEngine 5.12.1, where all the UI (other than menus) lives in a window filled by a QtWebEngine widget. Screen readers see the native menus, of course, but so far I have been unable to get them to "see" into the web content such that they can leverage web accessibility features. When focus goes into the hosted page, the screen reader goes silent.

Is this possible / supposed to work? Same result with the sample QtWebEngine widget-based apps I've tried.

Only tried on Mac so far (using Voiceover), but will also be trying Windows with various screen readers.

Hi,

is it possible to call a signal or method from a website within WebEngineView which calls a function in qt/qml.

I tried to add a click listener to a button but i can't react to the result.

onWindowsCloseRequested reacts to window.close(). Is there a similar slot for custom calls?

Hope you can help me.

Unsolved How to have a different initial background color for popups shown with <select>?

I have an application using a QWebEngineView . In this QWebEngineView, I use a <select> to display a popup menu. The application itself and the popup are customized to have a black background color. However when the popup is shown, a white background is initially used: it seems to flash shortly white.

0_1552477420705_WhiteBackground.png

I tried to set an initial black background color to the popup with no success. I made a subclass of QWebEngineView to catch the childEvent events. I was able to get the QEvent::ChildAdded and QEvent::ChildPolished events. I can get the QWidget pointer, however have not been able to change the background color.

void AAAAAAWebEngineView::childEvent(QChildEvent *e)
{
	QWebEngineView::childEvent(e);
	
	if (e->child()->isWidgetType())
	{
		if (e->type() == QEvent::ChildAdded || e->type() == QEvent::ChildPolished)
		{
			QObject *child = e->child();
			QWidget *widget = dynamic_cast<QWidget *>(child);
			if(widget != NULL)
			{
				widget->setStyleSheet("background-color: red;");
			}
		}
	}
}

One of the QWidget I get is a RenderWidgetHostViewQtDelegateWidget with the property m_isPopup set to true, so I guess this is the right QWidget. Trying to change the background color using a style sheet has no effect.

Does anyone know how to set a different initial background color for popups shown with <select>?

In QWebEngineView: How to obtain the link clicked by "right-click" + "open in new tab"?

Actually I've succeded to catch the action of "open in new tab" (after right-click) by doing this:

QAction* openInNewTab = view->pageAction(QWebEnginePage::OpenLinkInNewTab);
connect(openInNewTab, SIGNAL(triggered()), this, SLOT(on_actionNewTab_triggered()));

But in my slot on_actionNewTab_triggered(), I have no possibility to know which url to load. I tried to know if there is something in the data of QAction*

QVariant va;
QAction* action = (QAction*)  sender();
va = action->data();

but the data (va) contains no url !

Unsolved QtWebengine 5.12.2 - Compiling from source (Mac OS X) with webengine-proprietary-codecs not working

Hi everyone,

I've been trying to compile the new version of Qt 5.12.2 on Mac OS X with the option webengine-proprietary-codecs, however, I didn't succeed to pass it to any configure/qmake command (I'm using qt everywhere sources)

I'm passing it to the top level configure:

OPENSSL_LIBS='-L/usr/local/opt/openssl/lib -lssl -lcrypto' ./configure -webengine-proprietary-codecs -opensource -nomake examples -confirm-license -openssl-linked -I /usr/local/opt/openssl/include

But the answer is:

ERROR: Unknown command line option '-webengine-proprietary-codecs'.

When I do a --help on configure, I can see it as one option available.

I also tried to go to the qtwebengine subfolder and do:

../qtbase/bin/qmake -- -webengine-proprietary-codecs

But the answer is:

Project ERROR: You cannot configure qtwebengine separately within a top-level build.

So why the top-level configure doesn't accept the option?

I read a lot of things online, they are mostly about Windows and previous version of Qt, don't know if anything changed recently.

Thanks for your help,

Hello, everybody!

At work the task connected with adding of API for QTWebEngine for internal needs of the company arrived to me. The project uses the old Chromium engine (49) version, it is built for the SailFish OS operating system. I unfortunately did not find any documentation on debugging QTWebEngine. The question arose how to debug part of the QTWebEngine wrapper over Chromium, as well as Chromium itself for a start on Linux. If anyone knows how or who may have a link to the documentation regarding this problem, please help :)

Unsolved communication from two webengine

Hi, I'm working with a QT-QML-WEBENGINE project.
When I open a QML file connecting a webengine object I can interact with QT / C ++ with the SLOT and SIGNAL system.
Through the onNewViewRequested event, started with window.open, I can act in a QML position through "Connections {target:".
Everything ok but ...
I have not found a way to get back to the control of the webengine.

Example:
in 2 qml files I connect webengine and in each one I load a html page controlled by specific javascript.
main.qml
     tabslipt
         primo.qml (component of main.qml)
             - pageA.html
                - javascript_pageA.js
         secondo.qml (component of main.qml)
             - pageB.html
                - javascript_pageB.js

If I'm on pageB I would like to start a function in javascript_pageA.js
If I'm on pageA I would like to start a function in javascript_pagieB.js

Is it possible according to you?
Thanks in advance
