I tried to sign and notarize example application "simplebrowser" from Qt5.12.7 examples.

If I sign the main application: simplebrowser.app/Contents/MacOS/simplebrowser with deep and runtime options It works perfect, but I cannot notarize this bundle because I have to sign simplebrowser.app/Contents/Frameworks/QtWebEngineCore.framework/Helpers/QtWebEngineProcess.app/Contents/MacOS/QtWebEngineProcess too. If I make this, I can notarize the application. But the program does not work on websites with Java Script.

Also I tried this solution: https://forum.qt.io/topic/102212/qtwebengine-signing-issues It does not work

Hello,

I have a little question regarding the download mechanism in QT-WebEngine.
For this I took a look at the example "simplebrowser".

There is a class "Browser" in which the "DownloadManagerWidget" receives a call to "downloadRequested". Then a path will be set where the download has to be saved.

The question I have is, how can I create my own QWebEngineDownloadItem, which will be created when the user hits "Save as"?

The background for this question is, that I would like to use that example to build a mini-download-manager, which will automatically download a file (no "Save as" user-action) whose url I read from the source-code (this I have already done).

If my question is not understandable, please let me know and I will try to precise.

Thanks,
Tom

I am cross-compiling Qt for ARM board. My source file is Qt 5.14.1 and tool chain is gcc-linaro-5.3.1.
This is my configuration :

#!/bin/bash

./configure \
        -v \
        -prefix /opt/Qt5.14 \
        -opensource \
        -confirm-license \

But it shows as below after run ./configure:

What does 'Platform unsupported' mean ? Is there any tutorial for cross-compiling Qt with qtwebengine?

We have a website that uses long-presses. When accessing this website from a WebEngineView in QML, we note that

• a long-mouse-press is handled correctly
• a long-touch-press gets translated to a right click

Note that we see the same behavior when accessing this webpage directly from Chromium. It works fine when opening this webpage from Firefox.

I assume that this happens because the long-touch-presses have mouse.source=Qt.MouseEventSynthesizedByQt while long-mouse-presses have mouse.source==Qt.MouseEventNotSynthesized

So I would like to make this webpage work in WebEngineView .
Which options do you see?

One option I see is to recompile Qt and remove MouseEventSynthesizedByQt. This is new to me so what is the best/suggested approach here?
Change (in qevent.cpp)

Qt::MouseEventSource QMouseEvent::source() const
{
    return Qt::MouseEventNotSynthesized; //QGuiApplicationPrivate::mouseEventSource(this);
}

or replace the limited number (< 10) of occurences where MouseEventSynthesizedByQt is used by MouseEventNotSynthesized?

I'm developing an SVG viewer. I tried QSvgRender+QGraphicsView, but it doesn't support text selection with the mouse. Finally, I find QWebEngineView works well. However, the zoomFactor range is 0.25~5 which is a shortcoming. I want to remove the limit and don't know if this thought is possible. Thanks!

Hello,
I ported a QtQuick QtWebengine based app that works very well on x86_64 for an aarch64 SBC. After cross-compilation and deployment, every aspect of the app like QtWindow QtControl, Images, etc worked fine
but failed to load QtWebengine.
When I run:

webengine_app -platform eglfs

I got multiple repeats of this error message on my ssh terminal, then it hangs:

[3844:3875:0218/130036.767422:ERROR:gl_context_egl.cc(199)] eglCreateContext failed with error EGL_BAD_CONTEXT
[3844:3875:0218/130036.767638:ERROR:gles2_command_buffer_stub.cc(262)] ContextResult::kFatalFailure: Failed to create shared context for virtualization.

I tested a fresh Webengine example: Qt Quick Minimal but got the same error messages. Other non-webengine examples like QtQuick Clock Example worked.

QtWebEngine - Android-Project ERROR: Unknown module(s) in QT: webenginewidgets

I built a Qt 5 application project on Android including webenginewidgets module. But I got a error as follows.

/Qt/5.13.1/android_arm64_v8a/bin/qmake -o Makefile ../videoplayer/videoplayer.pro -spec android-clang CONFIG+=qtquickcompiler
Project ERROR: Unknown module(s) in QT: webenginewidgets

Refer to https://doc.qt.io/qt-5/android.html

It says "Qt for Android enables you to run Qt 5 applications Android devices. All Qt modules (essential and add-on) are supported except Qt WebEngine."

But on Qt maintenance Tool it only indicates that webengine component, "On Windows, the module is only available under MSVC 2017".

I want to build a Qt 5 application project on Android including webenginewidgets module.
Is there any other method? Or Will Qt support webenginewidgets module in the future version?

Hi,
why in the QWebEngine (Qml and QWidget) I see a blank screen for a Web Esri Map instead with the browser anything it's ok?
Thanks

Hello, today i test QWebEngine module to make Web Browser, and i would like to make menu similar to the actual gnome 3 menu in the left (similar to Ubuntu style), and when mouse isn't into this menu, this menu disappear.
But how can i do that ? Is it possible to show picture into WebView, or i need to some other widgets ? What is your advice ?

Hi,
I'm working on an application which captures the contents of a QWebEngine and renderes it to a texture.
The original window of the QWebEngineView is hidden with setAttribute(Qt::WA_DontShowOnScreen).

We use this to map web content to 3D objects. This used to work fine with Qt 5.12. Starting with 5.13 it does not work anymore. I've tried to build now with several versions up to 5.14.1.

As soon as the window is hidden, the webengine does not receive any updates. I can also reproduce this by not setting the WA_DontShowOnScreen flag and then just minimize the window at runtime. This also breaks update.
So far I've not been able to find any workaround to get the updates back.

Thanks for any help!

I am having issues with a few errors regarding QWebEngine. I currently have a locally built version of Qt that sits in a folder at D:/BuiltLibraries and a folder for all of our built libraries in D:/Libraries. Currently, my locally built version of Qt sits in both.

I can build and run everything just fine. When others pull down the repository they can build everything but when they actually go to run the application they get one of the following errors:

qFatal: Could not find QtWebEngineProcessd.exe
or
qFatal: Could not find QtWebEngineProcess.exe

If I rename my D:/BuiltLibraries to something different I get the same error even though it's building with the copy of the library in D:/Libraries.

The repository that I am building is in D:/Repos/<repo> and builds to folders in there that are generated by Visual Studio. I've tried adding a qt.conf to the folder where the applications .exe is as well as adding a qt.conf file to the Qt library in D:/Libraries and can't seem to be able to get it to work.

When we build a installed version of our application we get a bunch of qWarnings saying it can't find the ICU data in D:/BuiltLibraries/Qt/resources. It at least falls back on the directory the .exe is located and finds everything and runs.

It seems that when Qt is built it hardcodes a path to look for what it needs. Is there a way to work around this issue in our build environment?

Hi,
I.am customizing a web browser,
but when I want to add some widgets to my QWebENgineVIew,
I have to resize the widget every time before it shows.

MyWebEngineView::MyWebEngineView(*parent) : QWebEngineView(parent)
{
	QVBoxLayout* layout = qobject_cast<QVBoxLayout*>(this->layout());
	qDebug() << layout;
	if (nullptr == layout) {
		layout = new QVBoxLayout(this);
	}
	layout->setSpacing(0);
	QToolBar* toolBar = createToolBar();
	layout->addWidget(toolBar);
	progressBar = new QProgressBar(this);
	progressBar->setMaximumHeight(1);
	progressBar->setTextVisible(false);
	progressBar->setStyleSheet(QStringLiteral("QProgressBar {border: 0px} QProgressBar::chunk {background-color: #da4453}"));
	layout->addWidget(progressBar);

	this->extendToolWidget = new QWidget(this);
	this->extendToolWidget->hide();
	layout->addWidget(this->extendToolWidget);
}

    MyWebView *webView = new MyWebView;
    MyWebPage *webPage = new MyWebPage(QWebEngineProfile::defaultProfile(), webView);
    webView->setPage(webPage);

    setupView(webView);
    webView->resize(currentWidget()->size());
    webView->show();

and when I show this widget , I can see my tool bar move from center to top, rather than always on the top.

so what can i do to make my tool ba stay on the top, Thank you.

I write a QtWidgets application that contains the QWebEngineView as a GUI component in order to display some HTML/JavaScript animated charts. The problem is that the animation is not displayed properly. The content is blocked at the begining and its final form is displayed after clicking some button, changing tab etc. - namely, after a GUI event.

My idea was to somehow create a QWebEngineWidget that is run in a separate thread. Is that possible?

Than you for any suggestions.

I run the webenginewidgets example simplebrowser in Qt 5.14, compile with VS2017. After the browser window show for a while, the web page can not been shown in the window. And then, a dialog box popup, it says "Render process exited with code: 40". I don't know what does this code mean and how to solve this problem? Is there any thing need to configure before compiling? How to generate the log file of QtWebEngineProcess.exe?
The system information of my computer:
os: Win7 64-bit
cpu: Intel i5-6500
Graphics card: Intel(R) HD Graphics 530

I am tring to cross-compile QT to Risc-v, why jump over webengine?
When we can get webengine for Risc-v?
