module "QtWebEngine" is not installed

[rostik]

Hi,
Two things come to my mind:

• QT += webengine
• #include <QtWebEngine/qtwebengineglobal.h> and QtWebEngine::initialize(); in your main.cpp

[ejos]

Thanks for the reply. But still I find the same issue even after including ur suggestion :(:(

@ejos Which Qt version are you using ?
Did you select it while installing Qt ?

[ejos]

yes. I am using Qt 5.4

I could find the QtWebEngine folder inside the Qt/src/qml

[p3c0]

@ejos Ok. Do you see QtWebEngine folder under gcc_64/qml (not src) ?
On my Linux system complete path is /opt/Qt5.4.1/5.4/gcc_64/qml/QtWebEngine viz. Qt installed directory.

[ejos]

Yes I am able to find.

@ejos Well I'm also not sure why it not works on Mac. May be someone else with that platform knowledge would answer. Or try reinstalling it once. QtWebEngine is supposed to work on Mac too. https://wiki.qt.io/QtWebEngine

[ejos]

While using QWebEngineView , Is there an option like QDeclarativeContext / QDeclarativeEngine where to QML context is set from CPP file.

[p3c0]

@ejos No, atleast I haven't come across. QWebEngineView is a pure C++ class.
Did you try reinstalling ?

[ejos]

haven't tried yet, will do that.
After including the includes QtQuick or QQml in the header file getting errors as below

kindly help to resolve this issue

@ejos What did you include and where ?

[ejos]

The issue was with mismatch of QDeclarativeView and QQuickView use simultaneously. The issue is resolved once I changed all QDeclarativeView to QQuickView.

Thanks for replies
