Unknown module(s) in QT: webkitwidgets

Nite Coder

Sorry, I did do that, I just wrote it down wrong. Its still is an error.

//My actual .pro file
TEMPLATE +=app
QT+= webenginewidgets
CONFIG+= c++11

mpergand

Try:
QT += widgets webenginewidgets

Nite Coder

It still won't work. Is it my version? Qt 5.10.1

Look at the .pro file of the DemoBrowser in the Examples folder that come along with Qt.

Nite Coder

I did. That's what was in the .pro file.

//Simple Browser .pro File

TEMPLATE = app
TARGET = simplebrowser
QT += webenginewidgets
CONFIG += c++11

HEADERS += \
    browser.h \
    browserwindow.h \
    downloadmanagerwidget.h \
    downloadwidget.h \
    tabwidget.h \
    webpage.h \
    webpopupwindow.h \
    webview.h

SOURCES += \
    browser.cpp \
    browserwindow.cpp \
    downloadmanagerwidget.cpp \
    downloadwidget.cpp \
    main.cpp \
    tabwidget.cpp \
    webpage.cpp \
    webpopupwindow.cpp \
    webview.cpp

FORMS += \
    certificateerrordialog.ui \
    passworddialog.ui \
    downloadmanagerwidget.ui \
    downloadwidget.ui

RESOURCES += data/simplebrowser.qrc

# install
target.path = $$[QT_INSTALL_EXAMPLES]/webenginewidgets/simplebrowser
INSTALLS += target

Hi
Make sure to delete the build folder
and re-run qmake from build menu to make sure .pro file is 100% parsed again.

Nite Coder

What is the build folder? Sorry if I am asking a lot of, probably pointless, questions. But I appreciate the help.

mrjj

@Nite-Coder
All questions are fine.
The build folder is where it puts all generated files. all the .o files etc.
Its normally located on same level as the project folder.
and named something like
build-PROJECTNAME-Desktop_Qt_5_10_1_CompilerName-Debug

if you are using shadow build. you can see it in projects
alt text

If issue finding it then
Open project
Right click on any file in proejct
select Open containing folder
The file explorer should come.
Go one step up/ back
you should see folder. ( that is if u did build the project)

Nite Coder

Okay, I did that and it still didn't work. I deleted the build folder and re-built it.

mrjj

@Nite-Coder
ok so we know u 100% have
QT += webenginewidgets

I wonder if its installed ?
It has to be selected during install if not whole group was selected.
If you used the online installer, you can use
MaintenanceTool.exe in Qt folder.

Nite Coder

Okay, I have the Maintenance Tool. But it is a .dat file. Do I have to run a chmod command to get it running? And what would the chmod command be. Thanks for upvoting me mrjj!

mrjj

@Nite-Coder
Hmm. I just releasize you are on linux. :)
Did you use online installer or got Qt via distro ?

update:
should be something like
alt text

Nite Coder

I used the online installer after using the distro's repositories. Would that affect anything?
Edit: I got the .dat and .ini

mrjj

@Nite-Coder
So you dont have the ".exe" ?

Nite Coder

No I don't...

Im not 100% sure but i think easy route to install extra Qt version from
online to get the tool. ( and install in local user folder, NOT system wide folder )
If wonder if we can just copy exe. but i fear .dat is not updated.

Nite Coder

@mrjj
What is the local user folder?
And...
So you want me to install Qt again with the online install

I just managed to copy the .dat file so I could rename it o .exe. It opened up an archive manager and displayed an error message saying it couldn't open the file as a PE archive

mrjj

@Nite-Coder
well just in our home folder.
Not in /opt or anywhere rest of system might look for so files etc.
(just to be safe. not sure it matters)

Well it seems to be suggested that.
Else wait a few hours and maybe someone know how to apt-get it directly or
something faster.
we could also just try to copy my version and see but im not sure it has its right ini file and dat file then.
maybe you can apt-get webengine directly, but im not sure under which name/deb file.

the .dat file is NOT the exe. :)

Nite Coder

Thanks for the help mrjj! I upvoted you on every post : ) (Thanks for the upvote!) I think I'll wait. The apt-get method seems to be the best idea. But I'll try installing it again.

mrjj

@Nite-Coder
I agree. Its pretty normal to use distro Qt and for say unity i think it was
also needed for integration. So i assume there is some other way.
