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

[Cobra91151]

@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.

@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

@mrjj

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:

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

Now it's all compile and work.

@Cobra91151 Hi i also face same issue, you have any Qtwebkitwidgets install setup document?

[vadak]

@vadak Hi @mrjj ,i am facing one issue related to QT:webkitwidgets unknown module ,please help to solve this issue and now i am using QT5.7 and OS windows10 and i downloaded qtwebkit_tp4_qt57_msvc2015_x64.zip .
any setup document need for this? i am new to QT.

[mrjj]

@vadak

Hi
Did you try to copy as Cobra91151 wrote ?

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

[vadak]

@mrjj,no i am not copying anythink from @Cobra91151 ,and i also faceing same issue but i don't know how to add qtwebkit_tp4_qt57_msvc2015_x64.zip to my Qt5.7 MSVC2015 compiler.

[mrjj]

So you didnt try like he wrote ?

[vadak]

@mrjj yes

[mrjj]

Ok but you should to that then.
and dont forget to run qmake from build menu when you change the .pro file.

[vadak]

so i need copy this qtwebkit_tp4_qt57_msvc2015_x86.zip to C:\Qt\5.7\msvc2015; to qtbase is enough and i need following below step is enough? . and i will give qmake ?.

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;

[mrjj]

@vadak

Why not try it. ? ( i have not)

He says to unpack the zip to that location (Copy the contents ). not copy whole zip file.
he says it then worked for him.
And after you alter your .pro file, you must run qmake from build menu.

[vadak]

@mrjj issue is resolved ,thanks for your support.
