    Hi,

    Based on the name, it should be a layout and not a QFrame.

      Hi
      From the code here
      https://github.com/PacktPublishing/Hands-On-GUI-Programming-with-CPP-and-Qt5

      its a
      QVBoxLayout *webcam about;
      (and code just compiles)

      so maybe bug in book or something like that ?

          Hi
          That is super odd.
          it really is included in the download
          alt text

          Did you move the files around or anything like that ?

          I can see it says

          '..\Chapter09\mainwindow.ui'

          Like its relative to the pro file
          However, the .PRO file says

          FORMS +=
          mainwindow.ui

          so I wondered if you moved the .pro file or anything ?

              @lse123
              Im not sure what you mean but if
              the projects are in different folder, its not an issue that
              they have same names.

              But you really didnt answer if you did anything to the files after download as they do compile fine here?

              So if you are not using the project as it, please tell what you do.

                  @lse123 I can build Chapter09 without issues - but I only opened Chapter09 project. But I noticed that there is Webcam.pro.user after git clone - this should not be part of the repository!
                  Try to delete Webcam.pro.user file, delete build directory and rebuild.

                      Do you use Qt Maintenance Tool?

                            I would try to change the mirror, you might be hitting a faulty one.

                                    you can also download offline installer
                                    https://www.qt.io/offline-installers
                                    Its bigger up front download but the same things that gets installed.
