qtwebengine

问题 I'm working on porting a Qt 5.5, QWebView project to Qt 5.6 (beta), QWebEngine. I've gone through the porting guide here. My code looks like this: .h file defines _view like so: QWebEngineView* _view; and the .cpp constructor (class inherits from QWidget) has: QVBoxLayout* vbox = new QVBoxLayout(this); _view = new QWebEngineView(this); connect(_view, SIGNAL(loadFinished(bool)), this, SLOT(loadPageFinished(bool))); QString webDir = getReportBasePath() + no_tr("/index.html#") + startingPage; //

问题 I am trying to build Qt using meta-toolchain-qt5 , but when I do this via poky-glibc-x86_64-meta-toolchain-qt5-cortexa7hf-vfp-vfpv4-neon-toolchain-2.0.1.s‌​‌​h , I don't see anything about QtWebEngine in the sysroot directory. I also tried to build Qt using the following command bitbake meta-toolchain-qt5 but it is the same result; I don't have anything regarding Qt WebEngine. How can I build Qt with QtWebEngine support? 回答1: Looking at meta-toolchain-qt5 it inherits populate_sdk_qt5 , which

问题 I have a QtWebEngineWidgets showing some pdf files. I want to change pdf and force QtWebEngineView display automatically and dynamically. The problem I get is the QtWebEngineWidgets does not update, incapabile to display when pdf file path changes. class PdfReport(QtWebEngineWidgets.QWebEngineView): PDFJS = 'file:///pdfjs/web/viewer.html' def __init__(self, parent=None): super(PdfReport, self).__init__(parent) self.PDF = 'file:///Technicalreport/file0.pdf' self.load(QtCore.QUrl.fromUserInput(

问题 Qt WebEngine This link show python wrapper for Qt WebEngine . Please can canyone tell me how can i add this in pyqt5 environment? Thanks!!! 回答1: It seems I got it working: Either install pyqt version 5.10, which still ships the web engine, either install a newer (I use 5.12) and install PyQtWebEngine separately. pip3 install PyQtWebEngine Now these imports work: from PyQt5.QtWebEngineWidgets import QWebEnginePage from PyQt5.QtWebEngineWidgets import QWebEngineView I can't tell you the whys, I

问题 I am trying to build an app in PyQt5 (version 5.6+) in Python 3.6. It contains a web browser, using QtWebEngineWidgets. It works fine on Mac, however, there are problems on Windows. When I run the code on Windows and import the module: from PyQt5 import QtWebEngineWidgets I get the following error: ImportError: cannot import name 'QtWebEngineWidgets' Now, reading some forums it looks like PyQt5.QtWebEngineWidgets is not available for Windows, yet. Is it correct? How can I have a web browser

问题 I'm trying to create a Dialog in Qt which loads a URL (which I do not want to expose to the end-user, hence a Dialog). Once the user has entered their credentials on the page, the server returns a redirect URL which I want to capture. How can I do this? QtWebkit made this easy to do as QWebView had a QNetworkAccessManager object. But with QtWebEngine, the QWebEngineView class does not have this capability. The former also allowed HTTP headers to be set for any requests by using the

问题 I was playing around with QT WebEngine to make a desktop web browser which suits my requirements while working. Unfortunately, I need send some data with the HTTP Header to a site. I came across QWebEngineUrlRequestInfo class' void QWebEngineUrlRequestInfo::setHttpHeader(const QByteArray &name, const QByteArray &value) method but I don't really know how to use it in code. This is my code so far: import QtQuick 2.7 import QtQuick.Window 2.2 import QtQuick.Controls 2.0 import QtWebEngine 1.3
