QtWebEngine

I figured out a solution. Instead of loading files using the file:/// protocol, I used a custom scheme. I then used QWebEngineUrlSchemeHandler:requestStarted to open the files and attach them to QWebEngineUrlRequestJob. void UrlSchemeHandler::requestStarted(QWebEngineUrlRequestJob* request) { QByteArray requestMethod = request->requestMethod(); QUrl requestUrl = request->requestUrl(); QString requestPath = requestUrl.path(); QFile* file = new QFile(requestPath); file->setParent(request); Z_VERIFY(connect(request, &QObject::destroyed, file, &QFile::deleteLater)); if (!file->exists() || file->size() == 0) { request->fail(QWebEngineUrlRequestJob::UrlNotFound); return; } QFileInfo fileInfo = QFileInfo(*file); QMimeDatabase mimeDatabase; QMimeType mimeType = mimeDatabase.mimeTypeForFile(fileInfo); request->reply(QUrl(mimeType.name()).toEncoded(), file); }

anyone have idea?

@JonB Thank you so much! I see this is different than I thought. Works good!

@jiapei1000 Please post the actual error - it should be somewhere above of what you posted.

I have the same problem, but in PyQt 5. Ended up using an alternative solution with an external "keyboard" library that mimics keyboard presses: if self.page().contextMenuData().isContentEditable() == True: #check if an input field was right-clicked self.menus = QMenu() action1 = QAction("Paste text", self) self.menus.addAction(action1) self.menus.popup(event.globalPos()) action1.triggered.connect(self.paste_into_field) def paste_into_field(self): keyboard.press_and_release("ctrl+v")

我也遇到了相同的问题 I had the same problem

@RicTa said in WebEngine Nanobrowser not able to pass Antibot Validation: indeed in the meantime I have open this bug here: https://bugreports.qt.io/browse/QTBUG-107451 please let me know in case I made some mistakes in creating it. thanks a lot for you support Thanks! Your bug report looks fine to me, and I see that you are having a productive discussion with an engineer who is working on Qt WebEngine.

Bug has been logged. https://bugreports.qt.io/browse/QTBUG-107502

did you guys resolve this problem now? I encountered this problem on Qt 5.15.2, when I use following setting: QCoreApplication::setAttribute(Qt::AA_UseSoftwareOpenGL);

Yes, you are trying to link libraries built from different architectures. Those OSX flags were my attempt to see if they would stop building ARM. But it seems that they are still trying to build ARM and link to x86_64.

Did you take a look at this example videoplayer? It appears the widget has to listen to the QWebEnginePage::fullScreenRequested signal.

@nodeepshit said in How to save QWebengine log: I modified the parameters as below, the log did't appear either. Is there any sample project to demonstrate how to achieve this. #include "TestQWebEngineView.h" #include <QtWidgets/QApplication> int main(int argc, char *argv[]) { std::vector<char*> new_argv(argv, argv + argc); new_argv.push_back(const_cast<char*>("--disable-web-security")); new_argv.push_back(const_cast<char*>("--enable-precise-memory-info")); new_argv.push_back(const_cast<char*>("--enable-logging")); new_argv.push_back(const_cast<char*>("--log-level=0")); argc = argc + 4; qputenv("QTWEBENGINE_REMOTE_DEBUGGING", "7777"); argv = new_argv.data(); QApplication a(argc, argv); TestQWebEngineView w; w.show(); return a.exec(); }

Can you enable QWebengine log and see what's hapening when white screen occurs.

Since I guess this is impossible, I will convert the PDF to a image using pdf2image and work with images

There's the MSVC version of Qt according to an answer on this thread: https://forum.qt.io/topic/139011/how-do-i-install-qt-web-engine-for-qt-6-3-1/4
