Project ERROR: Unknown module(s) in QT: webkitwidgets

Cobra91151

Hi! I get the error: Project ERROR: Unknown module(s) in QT: webkitwidgets when included QWebView

.pro

QT += widgets core gui network webkitwidgets webenginewidgets concurrent

.h file

#include <QWebView>

or

#include <QtWebKitWidgets/QWebView>

Also when hover on the include it displays: No such file or directory

Qt version: 5.7.1.
I can't use QWebEngineView because it breaks my application theme. How to include QWebView? Thanks.

Hi
Please see here
https://forum.qt.io/topic/76739/webkit-status-2017

Its no longer part of the official download.

@mrjj

Thanks. Also I have checked C:\Qt\5.7\msvc2015\mkspecs\modules directory and qt_lib_webview.pri module exists but not qt_lib_webkitwidgets.pri. So I need to build it by myself?

mrjj

@Cobra91151

Hi,
There is downloads as link says
https://github.com/annulen/webkit/releases

So i think there is no need to build one yourself if you can find the right version

There is
qtwebkit_tp4_qt57_msvc2015_x64.zip
which might suit you fine?

Cobra91151

@mrjj

Ok. I need x86. So I have downloaded the qtwebkit_tp4_qt57_msvc2015_x86.zip.

For example:
Path: C:\Qt\5.7\msvc2015

So I need to copy it to the Qt directory?

mrjj

@Cobra91151
Thats a good question how to correctly install.
But yes, it should be copied into place so the module etc works
but never tried it myself :)

There is no install doc in zip or anything like that?

Cobra91151

@mrjj

Yes. It compiles. Thank you.

@mrjj

The problem now is with the object:

test.h
QtWebView *mapBrowserView;

Errors:

error: C2143: syntax error: missing ';' before '*'
error: C4430: missing type specifier - int assumed. Note: C++ does not support default-int

So it doesn't work. I think installation should be different.

Using QtWebKit in your project
https://github.com/annulen/webkit/wiki/Using-QtWebKit-in-your-project

I will try to compile it.

Cobra91151

@mrjj

It's all already compiled, so I don't need to recompile anything. It seems I have circular include QtWebView but I included it only once. It's strange.

mrjj

@Cobra91151
Ok, i assume it would be precompiled as else no reason for compiler versions.

It seems I have circular include QtWebView but I included it only once. It's strange.

You can turn on Include view and see if something shows up

My includes screenshot:

Maybe this project has (https://github.com/annulen/webkit/releases) circular include, or bugs in the code.
Also I have downloaded qtwebview-opensource-src-5.7.1 from official Qt source. But I don't know where to install it? Is there any documentation link how to install submodules? Thanks.

Hi, normally you would do
qmake
make
make install

for such a source zip

Cobra91151

@mrjj

I will try it. Thanks.

@mrjj

I get 'qmake' is not recognized as an internal or external command, operable program or batch file. when running on qtwebview-opensource-src-5.7.1 (Developer Command Prompt for VS2015)?

I have these files after extraction from archive:

Should I copy these files to the path: C:\Qt\5.7\Src\qtbase and qmake
make
make install?

Cobra91151

@Cobra91151

I have reinstall Qt 5.7.1 and my .pro include is QT += widgets core gui network webview concurrent

test.h
#include <QtWebView>

But the error is the same when initialize QtWebView *mapBrowserView;

QtWebView is not the class, it is the namespace, image:

Cobra91151

Now I have figured it out - Qt WebView provides a way to display web content in a QML application but I'm developing Win API application only for Windows OS. So it will not work.

Cobra91151

So here is how I have fixed it:

Copy the contents of the archive qtwebkit_tp4_qt57_msvc2015_x86.zip to C:\Qt\5.7\msvc2015;
Include webkitwidgets to .pro file;
Include #include <QtWebKitWidgets/QWebView>
Initialized the QWebView *mapBrowserView; object;

Now it's all compile and work.

As far as I know there is no extra documentation available.
