    webengine != webkit. the first is based on the core of Google Chrome while the other is based on the core of Apple's Safari

    use QT += webenginewidgets

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

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

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

                    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)

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

                        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.

                          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!

                            Did you use online installer or got Qt via distro ?

                            update:
                            should be something like

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

                                    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.

                                      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

                                        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. :)

                                          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.
