Running QtWebEngine with C++

问题

I'm trying out Qt for the first time and want to create a very basic application which loads a website. I want to use Qt WebEngine.

This is my helloworld.pro:

TEMPLATE = app
TARGET = hello
DEPENDPATH += .
INCLUDEPATH += .

QT += webenginewidgets

SOURCES += hello.cpp

And this is my hello.cpp

#include <QApplication>
#include <QtWebEngineWidgets/QtWebEngineWidgets>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QWebEngineView *view = new QWebEngineView(parent);
    view->load(QUrl("http://qt-project.org/"));
    view->show();

    return app.exec();
}

When trying to compile I get the error:

Project ERROR: Unknown module(s) in QT: QWebEngineView
Project ERROR: Unknown module(s) in QT: webenginewidgets

I guess I know that it cannot find the modules, but looking into the qt-documentation it seems as the right way to include them.

I'm running QtCreator 3.4.2 on Qt 5.5.0.

回答1:

It looks like it is only supported on a few compilers right now:

http://wiki.qt.io/QtWebEngine#Q:_On_which_platforms_will_it_run.3F

Try building with one of those configured, and it should work.

My guess is that basically the Chromium project it is built on is very complex with lots of dependencies and QtWebEngine hasn't been backported other compilers yet.

QtWebKit should still be supported most of the time, but QtWebEngine is where things are headed.

Hope that helps.

Webkit package installation can resolve the issue: [apt-get install libqt5webkit5-dev]
