qtwebengine

问题 I'm using the new Qt5.4 with the module QtWebEngine and from what I see mainFrame() doesn't exists anymore. How to get the contentSize/size of the page and how to render it now? I tried with the setView and view but doesn't work. 回答1: Check if the QWebEnginePage::geometryChangeRequested signal does what you want. Also you display a QWebEnginePage by creating a QWebEngineView (it's a QWidget ) and calling QWebEngineView::setPage(yourPage) . 回答2: I couldn't find any native Qt method for that,

问题 I made a simple web browser but when I access to https://get.adobe.com/jp/flashplayer/ It says Adobe Flash Player is already installed, but disabled However as I read http://doc.qt.io/qt-5/qtwebengine-platform-notes.html It says that pepper flash plugin should be automatically loaded if there is a proper dll file. I checked my C:\Windows\System32\Macromed\Flash\ and I'm sure that I have a pepflashplayer32_21_0_0_213.dll there. Then I also set QWebEngineSettings *websetting =

问题 I'm creating an application using QWebEngineView and QWebEnginePage. I was wondering if there is a way to active the Web Dev Tools? I need to debug the html, javascript code like you do it using Google Developer Tool on Chrome. If it is not possible in QT 5.4 does anyone know when it is planned to be included in future versions of QT ? 回答1: add these line to your code #ifdef QT_DEBUG qputenv("QTWEBENGINE_REMOTE_DEBUGGING", "9000"); #endif after launching your application start google chrome

问题 I'm looking to replace QWebKit with QWebEngine in my headless renderer. I initialise the page with load() and connect a slot to loadFinished() to generate the final .PNG image. This used to work fine with WebKit but fails with QWebEngine . Code is as follows... _webView = new QWebEngineView(); .... // Render the HTML to an image QPainter painter(&image); _webView->page()->view()->render(&painter); painter.end(); I receive the following errors : "Asking for share context for widget that does

问题 I have the following method in one of my C++ classes (using QtWebEngine): QString get() { QString result; view->page()->runJavaScript("test();", [this](const QVariant &v) { result = v.toString(); }); return result; } It is to execute test() JS function and return the result of this invocation. Unfortunately, the callback is asynchronous and the program crashes. How can I make it work? 回答1: The callback is asynchronous because the JavaScript execution occurs not only in another thread but in

问题 I'm trying to use protobufs v 3.3.2 with Qt 5.9.1. This works with some Qt applications, but only if they are command line programs. Once I create a GUI application with Qt and protobufs, I get this error: [libprotobuf FATAL /home/mkraus/Documents/dev/star385/build/linux-desktop-debug-libs/protobuf/src/src/google/protobuf/stubs/common.cc:78] This program was compiled against version 2.6.1 of the Protocol Buffer runtime library, which is not compatible with the installed version (3.3.2).

问题 Saving an image of a webpage with a WebEngineView works fine, but when I want to scroll and save another image, the resulting image does not show the website has been scrolled (it shows the top of the webpage). My question is: how do I scroll down in the QWebEngineView then save a screen shot that shows the correctly scrolled webpage? I take a screenshot at the top of the webpage, scroll down ~700 pixels, wait for a javascript callback to trigger which then takes another screenshot. The

问题 I have an application (audio player for http://vk.com) which uses OAuth 2.0 authorization. What i did was that i implemented QtWebEngineView object and used it to open an authorization page. Basically, it looks like currently i'm using quite a big class for such a little job. Anyway, i need to make a static build of my application — unfortunately, from my researches i've discovered people saying that making a static build of QtWebEngine-dependent application is not possible for some reasons.
